Is a bathroom needed in a bathhouse? How to make a toilet in a bathhouse: available options and detailed construction technology Bathhouse and toilet under one roof.

Even before starting to lay the foundation of a bathhouse, its future owner should have a clear understanding of what it will ultimately be like. It is important to carefully consider what the structure of the room will be like, its decoration, as well as what the stove and plumbing system will be like.

And only after such a detailed plan has been drawn up, you can safely purchase materials and begin the construction process itself.

It is known that for many of us, a bathhouse is not just a place for washing. Bath procedures are, one might say, a whole ritual. The sauna is a good opportunity to relieve stress, improve your health and have fun with friends. That is why a modern bathhouse has several rooms for such complete relaxation.

Water can be supplied to the washing compartment of the bathhouse if this room is constantly heated. A heater needs to be installed in the shower room. Only cold water is supplied from the house, and it is heated in the bathhouse itself. Faucets for supplying cold and hot water, as well as shower heads are installed. The result is a modern shower room.

The water can be drained into a crushed stone filter. Since this wastewater contains a small amount of BAC, it is considered “gray”, so you can safely bypass the septic tank. A simple sump will do.

Of course, it is important that the shower room has good thermal insulation and is lined with moisture-resistant materials.

Toilet

Many experts agree that a bathroom in a bathhouse is extremely necessary. Especially in winter and especially if children take bath procedures. Of course, there are some nuances here that are very important to take into account.

Firstly, these are sanitary standards. The septic tank must be absolutely complete, because this wastewater is classified as “brown” and must be isolated from wastewater from the shower.

Access to the septic tank must be provided for a sewer truck.. You can also direct the drain into the general sewer system.

Another option is to install a dry closet. By dedicating a separate room or part of the shower room to the toilet, you can make it hygienic. When the bathhouse is not in use, the dry closet can be taken into the house.

Another feature of installing a toilet is, again, related to heating the room. In order for the plumbing to function properly, the bathhouse must be constantly heated.

Arrangement of the utility block

The utility block allows you to make a bathhouse not just a bathhouse, but a building where you can also cook food, receive guests, and relax. This allows you to free up a significant part of the residential building and use a separate room for economic purposes.

Of course, the design of a bathhouse with a utility block should differ in the following parameters:

  • convenient entrances to the premises;
  • good water supply;
  • heat exchange networks;
  • security measures.

It is worth paying special attention to the last point, since you may need to use both the bathhouse and the utility unit at the same time. Therefore, safety rules must be followed. Good thermal insulation of the room, ventilation system and the use of moisture-resistant materials are also important here.

Using block containers

The use of block containers greatly simplifies the construction of bathhouses with a toilet, shower and utility unit. They include everything you need, including suitable furniture. Block containers for bathhouses are lined with wood inside, and their design corresponds to a classic Russian bathhouse. The entire structure is completely fireproof.

In addition, if necessary, such a bath can be easily transported or moved to another location. All necessary equipment is included in the kit.

Toilet in the bathhouse

Toilet in the bathhouse

We will look at when and why to install a toilet in a bathhouse a little later in this article.

Let's start with the main thing - this is the technical side of the issue of installing a bath toilet. The drainage of water and condensed steam in the steam room through pouring floors is very different in chemical composition from sewage from the toilet. Therefore, if wastewater is not transported by sewer trucks to settling tanks, then such wastewater must be separated. Or install a water treatment system designed for large volumes of wastewater.

To operate a toilet in a bathhouse, you need a septic tank, which will filter the wastewater coming from the toilet. And the drains from the bathhouse must also comply with sanitary standards. Simply draining water onto the ground is not only harmful to the site, but is also prohibited by sanitary standards.

If installing a septic tank for sewerage next to the bathhouse is not planned, or does not fit into the budget for building a bathhouse, then a dry closet can be an alternative option - this is a simple and inexpensive solution

Why install a toilet in a bathhouse?

There can be many reasons, and all of them are justified. For example:

  • When you use a sauna in winter.
  • Or do you prefer to relax in a bathhouse with a campaign.
  • When a fence is made around the bathhouse area from a chain-link mesh.
  • When you have small children.
  • When you just want comfort.

If you are going to install a toilet in a bathhouse, then it makes sense to think through this point at the bathhouse design stage, when a floor plan is created and building materials for the bathhouse are calculated. The toilet area for the bath should be separated from other compartments. There should be a wall and a door between them. And the toilet room itself must have a ventilation hood with a pipe. This way your sauna will exude exclusively sauna aromas. And using it will become even more comfortable than a regular bathhouse.

Bathhouse project with toilet

In conclusion, I would like to give an example of a project for a bathhouse with a toilet. The diagram shows a one-story version of a bathhouse measuring 6x5 meters with an open terrace and a toilet in the bathhouse, separated from the rest of the bathhouse premises.

Scheme of a bathhouse with toilet and shower. Dimensions in the photo.

For similar projects of a bathhouse with a toilet, when a flush toilet is installed during the design, it is necessary to calculate the water supply system, water supply and drainage. For example, cold water for flushing the toilet and sink can be supplied from a well or borehole to a tank in the attic of the bathhouse. And warm water comes from an electric water heater, or, even simpler, also from the attic, from a tank located directly above the sauna stove - there are tanks through which the chimney of the sauna stove passes and heats the water during combustion. The main thing is not to forget that there is water there.

How to make a toilet in a bathhouse

Gone are the days when citizens, washing in their bathhouse, ran out of small or large needs “behind the bathhouse.”
Now all such issues are resolved in a civilized manner, because a toilet in a bathhouse is not a luxury, but an urgent necessity.

Of course, if you go to the bathhouse to quickly wash yourself or take a steam bath at high speed, then you don’t need a toilet in the bathhouse. But if you are a fan of bath procedures, then a bath bathroom is the same for you as a relaxation room and a bath veranda.

How to ensure the functioning of the toilet in the bathhouse and how to equip it - more on that below. The first thing that needs to be done, even at the planning stage, is to provide a room in the bathhouse to accommodate the toilet. It is better if it is located inside the bathhouse. Leaving the bathhouse and sitting in a cold annex is not the most pleasant experience.

Water supply to the toilet in the bathhouse

Next, the question arises - how to arrange a water closet in a bathhouse. To do this, add water to the bathhouse. In the case of year-round use of the bathhouse, you should think about how to insulate the bathhouse water supply and ensure the supply of water to the bathhouse all year round. There is a separate article about this on our website “How to arrange a bath water supply.”

A modern toilet in a bathhouse is a quite presentable room with plumbing fixtures

The toilet should also be powered from the bath water supply.

Draining water from a toilet in a bathhouse

Water from the toilet can only be discharged into the sewer. You cannot drain the toilet in the same place you drain the steam room or wash compartment (usually a container in the ground or a pit with a gravel filter).

For a bath toilet, provision should be made to drain water into the sewer system of the house and then into a cesspool, septic tank or VOC.

Toilet in the bathhouse in winter

If you have a heated bathhouse that maintains a positive temperature all year round, there will be no problems with the toilet in the bathhouse.

If you have an unheated bathhouse, which you use all year round, you will not be able to make a water closet in the bathhouse - the water in the tank and pipes will freeze and split both the tank and the toilet.

In this case, you can make a regular village toilet in the extension, but insulate it to make staying in it more comfortable in the winter.

Or you can use a dry toilet, which you will fill only while you are in the bathhouse and empty it after leaving the bathhouse. The liquid in the dry closet will also freeze in an unheated bathhouse.

You can leave a comment.

One of the main purposes of a bathhouse is to have a pleasant pastime. That is why a modern bathhouse should have all the necessary amenities, including a toilet.

All bath toilets can be divided into 3 groups: outdoor attached, mobile and stationary. The choice of a particular option depends on many conditions: architectural nuances, climate, financial capabilities, personal preferences.

Outdoor attached

An attached outdoor toilet is a traditional option that has been used for a long time as the only correct one. And although modern doctors strongly do not recommend its installation, many bathhouse owners are still installing it. And this is not surprising, because such designs have a number of advantages:

  • They can be built at any time, both at the stage of assembling the log house and during the operation of the bathhouse;
  • Eliminates the possibility of unpleasant odors forming;
  • The internal area of ​​the premises is preserved;
  • The entrance to the toilet can be made from two sides;
  • There is no need to empty utility networks for the winter;
  • You can choose any size and design.

Modern technologies make it possible to equip such a toilet quickly and cheaply. And to ensure a comfortable microclimate, an economical heater is installed.

How to attach a toilet to a bathhouse

Consider the option of a wood insulated toilet. The temperature is regulated by a heater. The cesspool is designed for 4 people. It is equipped with sand-lime brick, concrete rings, plastic barrels or concrete mortar. The parameters of the pit depend on the number of users and the frequency of cleansing.

Construction of the structure includes several stages:

  • Decide which wall the toilet will be installed against. When choosing, it is necessary to take into account the layout of the bath rooms and the distance of the cesspool from drinking water. Depending on the characteristics of the soil, this gap should be at least 10 meters on clay soils and at least 50 meters on sandy soils;
  • Mark where the doorway will be located in the wall of the bathhouse;
  • Cut a hole using a chainsaw;
  • Build a foundation for the toilet. Usually, its role is played by 4 columns measuring 40x40 cm, 50-60 cm deep. They are installed on a sand cushion no less than 15 cm high.

When creating a foundation, you need to understand that no matter what measures are taken to increase its stability, this will not protect against the formation of cracks between the base of the toilet and the wall of the bathhouse. To eliminate them, you can use insulating polyethylene foam tubes, tow, foam rubber or construction foam.

The actual construction of the toilet is carried out using frame or frameless technology. In the first case, 5x5 cm timber is used for the frame, polystyrene foam for insulation, and lining for wall cladding.

  • Assemble the frame of the required dimensions. Use nails or self-tapping screws for fixation, and iron corners to provide additional stability;
  • Check the spatial position of the structure: each angle must be equal to 90 degrees;
  • Perform lathing under the roofing;
  • Cover the walls with clapboard or planed tongue-and-groove boards;
  • Fix foam sheets about 2 cm thick on the inside;
  • Cover the walls with fiberboard sheets and wallpaper;
  • Make a pedestal over the cesspool or install a dry closet;
  • Lay a plank floor covering at least 3.5 cm thick. Since the width of the structure is small, there is no need to install floor joists - the boards can be mounted directly on the lower bars of the frame;
  • Cover the roof with any suitable material, for example, a metal profile.

The main part of the work has been completed. Now you can tackle the heating issue. To heat the bath toilet, it is recommended to use a conventional spiral fan. Its power will be enough to warm up a small building in just a couple of minutes. It is better to mount the device switch in the bathhouse itself and turn it on before visiting the toilet.

Mobile dry toilet in the bathhouse

A mobile dry toilet is a modern device that does not require construction work, water supply or a cesspool. To collect waste, there is a sealed container with peat, which is emptied as it is filled. On the one hand, this is quite convenient, but on the other, it is not very pleasant to be in a rest room, the corner of which is occupied by such a device. In addition, to remove recycled waste, you will have to regularly dig a small hole.

Conclusion

A toilet in a bathhouse is a necessary room, which is not at all difficult to make with your own hands. Moreover, for this you do not need to install intricate communication systems, because there are simpler, but no less effective options.

A bathhouse is, first of all, a place for comfortable relaxation, so it should have all the amenities. A toilet in a bathhouse is a necessary condition and its creation must be approached carefully and wisely.

If you ignore this question, there will be many situations in the future in which you will regret your decision. It is better, even at the stage of creating the project, to think about where the toilet will be located and how to connect communications to it.

If this point was not taken into account at the construction stage, then you still don’t need to despair - everything can be corrected. In this article we will talk about how to create a toilet in an already existing one and how to design it correctly. We will also describe in detail all the nuances of this process, provide a list of necessary materials and give useful advice regarding this issue. We hope that after studying our material you will have no questions or doubts and everything will turn out as well as possible.


Determining the location

Previously, bathhouses were built mainly without a toilet, since the toilet was located in the yard and everyone used it. There were no toilets in the houses either - they considered it something unnecessary. But modern man has become accustomed to comfort in everything and is no longer ready to put up with inconvenience even when visiting his own bathhouse. Therefore, installing a bathroom in a bathhouse is very relevant and in demand. The main nuance in this matter is the fact that the bathhouse, as a rule, is small in size, and it is not easy to allocate a space in it even measuring one meter by one meter.

In addition, it is finished with natural wood and the building itself is also often built from wooden logs, so the owners fear that it will be difficult to organize ventilation. After all, wooden surfaces absorb odors very strongly, and the toilet can ruin any vacation. But not everything is so simple here. If you choose the right location for the toilet and comply with all the technology requirements, the result will be quite reliable and acceptable.

So, the toilet must be located so that the entrance to it is not visible from the rest room; it is better to organize such a “nook”. This will not only avoid drawing unnecessary attention to such a delicate issue, but also possible odors will linger. Also, when choosing a place for a toilet, you need to take into account the location of the sewer pipe or septic tank on your site, since you will have to drain the drain exactly there and the shorter the distance, the lower the costs.

It is also worth saying a few words in favor of completely abandoning the toilet in the bathhouse, because such an opinion is quite common and even occurs more often than a decision in favor of comfort. So, a toilet in a bathhouse will lead to the following inconveniences:

  • you will have to increase or decrease the size of the interior spaces.
  • You will have to install a separate cesspool or obtain permission to tap into the sewer.
  • It will be necessary to supply water to the building and organize its safety in the winter, when the bathhouse is rarely used.
  • Purchase of plumbing and finishing costs.

But if all these problems don’t scare you, then let’s move on to the immediate description of the work.


Water supply

If you have already decided on the location and know exactly where the toilet and plumbing will be located in it, then you need to think about how to supply water to this location. This must be done at a stage when plumbing has not been installed and finishing work has not been carried out. If the bathhouse already has a shower, then the problem is reduced and you will only need to redistribute the water supply from this room. But if you go to the bathhouse, then there will be more worries.

The first thing that needs to be decided at this stage is how the bathhouse will be used in the winter. If you rarely visit it or it is located in a country house where no one lives, then the water will have to be drained from the system in cold weather. Otherwise, the water in the system will freeze and the entire structure will become unusable. If you don’t want to drain the water, or the bathhouse is located near the house, then you need to think about the heating system. In large baths, which are often used and in which a lot of time is spent, traditionally, a classic heating system is installed.

If there is no heating in your bathhouse, then you can simply insulate the water supply pipes; for this, special insulating sleeves are put on them at the installation stage. They are sold today in any hardware store. Of course, you can wrap the pipes with insulation and fix it, but this is very labor-intensive. In addition, special couplings will not only protect the pipe from freezing, but also prevent the formation of condensation. Therefore, there is no point in experimenting, especially since such couplings are very inexpensive.


The installation of a water supply must be approached responsibly and carefully, since the entire operation of the bathhouse will depend on the quality of the water supply. For water supply to the bathhouse, you need to use a plastic pipe with a diameter of 3-4 cm. When purchasing the necessary materials, you also need to purchase plastic corners and fittings that will be needed to connect the system. The plastic water supply system is connected using a special pipe soldering iron, so if you don't have one, it's worth thinking about where to get one.

Drain or sewer

Another fundamental point for installing a toilet is draining wastewater, that is, organizing a sewer system. This issue also needs to be resolved at the initial stage, that is, before finishing and installing plumbing. If you have a network sewer system, and you have the right to easily connect to it, then you can consider half the matter solved. You just need to remove the pipe from the bathhouse toilet and connect it to a common sewer pipe. If it is impossible to cut into the general sewer system, then you will have to build a separate cesspool and bring the pipe into it.


In the bathhouse itself, in the toilet, you need to install a pipe to which the toilet will subsequently be connected. To do this, you need to accurately determine its location and prepare the space for work. The fact is that simply running the pipe through a wooden floor will be wrong, as this will create a danger of the floor rotting and the spread of dampness. Therefore, it is better to at least lay the floor in the toilet area with ceramic tiles - make a square of 60 by 60 cm, but it would be more practical to lay the entire floor with tiles. But this is already finishing, and we are talking about drainage.

So, you need to cut a round hole in the floor, the diameter of which should be slightly larger than the diameter of the pipe. Lay a metal mesh on the floor equal in size to the planned tiles (60x60 cm or over the entire floor); the mesh must be shot to the floor with a construction stapler. After this you need to prepare it according to the following formula:

1 part water + 2 parts sand + 1 part cement

You will need a little solution at this stage, so do not overdo it. Now you need to carefully cement the prepared space and let it dry. At the same time, it is necessary to remove the drain pipe and secure it in the hole with a solution, this will ensure the reliability of the structure and prevent the spread of a damp environment. All this work will take about a couple of days to dry. The diameter of the pipe for the sewer outlet is usually 100 mm; this diameter is considered optimal for a toilet. Next, from the bathhouse the pipe is laid directly to the drainage point. If it is a sewer, then the pipe is connected directly to the main line. But if you decide to make a separate pit, then you need to say more about it. To finish the conversation about the pipe, it should be noted that the drain pipe must always run at a slight slope along its entire length. It should be buried approximately 50-60 cm into the ground, depending on the climate in which you live.


Construction of a cesspool

If the pit is made only for the bathhouse toilet, then it should not be very large. In this case, a pit with a depth of 2 m and a diameter of approximately 70-80 cm will be sufficient. You may think that this is too much, but believe me, this option will allow you to safely use the toilet without restrictions, and also resort to cleaning the pit as little as possible. In addition, such a pit takes longer to fill and cleans itself faster. The basic principles for creating a cesspool should be listed:

  1. The edges of the pit must be clearly vertical, this prevents fermentation of waste water.
  2. The bottom of the pit should be covered with a layer of gravel about 10-15 cm, so the water will drain faster and the pit will not deform.
  3. The pit must be closed with a special hatch (concrete or metal) with a lid on it. This will allow you to quickly clean it if the pit is full.

When a cesspool is installed for a residential building, concrete rings are installed in it, which ensures its reliability. But for a small pit designed only for a bath toilet, you don’t have to do this - you’ll only end up with significant extra costs. You can strengthen the walls of the pit with car tires. Once again, it is worth recalling that the drain pipe must enter the hole at an angle.


Septic tank and dry closet

Modern offers ordinary people solutions to the most complex issues, including the simple creation of a bathroom. Therefore, if you have no desire to tinker with the pit and everything else, you can purchase a ready-made dry closet, it includes:

  • A container with antiseptic liquid that solves the problem of waste disposal.
  • Toilet.
  • Drainage cistern.

These are the main components of such a system; they can have different configurations and appearance, but their essence is the same. Therefore, many today prefer such simple and practical devices.


As for the septic tank, everything is even simpler. Today there are many different options for such devices on sale, you just need to choose what suits you. Basically, septic tanks are distinguished by volume, so choosing is not difficult. The essence of this system is as follows: a septic tank is buried in the ground instead of a cesspool. The septic tank contains a special liquid that allows you to efficiently dispose of all waste. After a certain period of time, the septic tank must be cleaned and this liquid in it must be changed, but the period between replacements is very long.

Interior decoration

After you have installed water and sewerage into the bathhouse toilet, you can move on to the interior arrangement of this room. You will have to make some purchases for this work and it is better to purchase everything you need at once. So, here is a list of purchases:

  • Door to the toilet.
  • Toilet and cistern.
  • Ceramic tiles for finishing (you must first take measurements from the surface you will be finishing).
  • Tile adhesive.
  • Hinges and door fittings.
  • Accessories for the toilet (hose for water connection, siphon, circle, etc.).
  • Household toilet accessories (whisk, toilet paper holder, foot mat).

These will be your main purchases; you can add or remove something from the list at your discretion.

Now we need to consider step by step the internal work in the bathhouse toilet:

Laying ceramic tiles. Most often in a finished wooden bathhouse when installing a toilet. If you cemented part of the floor when installing the sewer system, then the work is simplified. If not, then you need to lay a metal mesh on the floor surface so that it covers exactly the distance that you will be tiling. Therefore, you need to prepare tile adhesive as indicated on its packaging. The tiles must be laid very carefully and evenly, checking your work with a building level. If you decide to lay tiles only around the toilet, and not along the entire floor, then the edge of the resulting space must be treated with plastic or metal molding, which is laid immediately under the tiles.


Toilet installation. As a rule, it does not take much time, the main thing is to do everything carefully and in exact accordance with the instructions included with the plumbing fixtures. The fact is that today there are many models of toilets on sale and different requirements may be imposed on their installation. Therefore, it is necessary to connect the tank to the water supply; to do this, you need to remove a special hose from the tank, which will be connected to the water pipe. Therefore, a siphon is installed in the tank, which is a ready-made mechanism, and the system is checked. The toilet bowl at its junction with the floor can be treated with a transparent sealant, this will avoid excess moisture on the floor.

Door installation. You can still install the door at this stage, but it is better to do this at the final stage. The fact is that if you lay tiles in the toilet, the door may get dirty during this work. The door must be installed in one day, clearly leveled and the space between the frame and the wall filled with polyurethane foam. After this, the door cannot be touched for about a day - it must dry.


A bathhouse with a bathroom is both a modern requirement for comfort, and in some cases an urgent need. Of course, toilet equipment creates a lot of additional problems associated with waste disposal, increasing sanitary standards, and most importantly, allocating space in a small building where the dimensions of all rooms are limited. When planning the construction of a bathhouse, you should correctly assess the need for a bathroom in it and the type of such establishment.

Bathroom in the bathhouse - a convenient option for a bathhouse and sauna separate from the house

Why problems arise

First of all, you need to decide whether a bathroom is needed in the bathhouse. Maybe it’s easier to run to an existing toilet if necessary? This issue must be resolved taking into account all the features of the bathhouse itself and its comfort.

Advice! If a stationary toilet is located very close to the bathhouse or it is used quite rarely, then it is not advisable to place the bathroom inside. The same can be said if there is a very small bathhouse in which there is no rest room.

In most cases, the need for a toilet inside a bathhouse is quite urgent. As a rule, private areas are fenced off with an openwork or mesh fence, which does not allow you to run to the toilet undressed, and getting dressed and undressing spoils the entire bathing procedure. If the bathhouse is used in the cold season, then it is generally difficult to do without a warm internal toilet, especially during a leisurely process with relaxation in the relaxation room. The relevance of such an institution is dictated by the presence of children. They definitely shouldn’t be allowed out into the street when they’re hot. Finally, the design of a bathhouse with a bathroom is about providing comfort and increasing prestige, when you are not ashamed to invite friends to take a steam bath in the bathhouse.


The bathroom is more suitable for a large bath or sauna with a relaxation room

What is the problem with placing a toilet in a bathhouse? The following circumstances can be highlighted:

  1. The need for a completely isolated area. Even taking into account the small dimensions of the bathroom, it is quite difficult to find additional space in a small bathhouse.
  2. Increased requirements for sewerage discharge. While wastewater from a bathhouse can be discharged into the soil through drainage wells, this cannot be done with toilet sewage. Feces must not be collected in pits or transported through chutes. They should be immediately collected in storage tanks or discharged outside through pipes. In this case, hydraulic locks are required that can eliminate odor.
  3. Ventilation. The role of ventilation is increasing, and in the bathroom it should have a forced exhaust character.
  4. Isolation. Water vapor should not penetrate into the toilet, which will condense on the structural elements. In addition, increased air temperature is also undesirable, because This all stimulates the spread of odors.

It is necessary to carefully consider the sewerage and drainage system in the bathhouse

Possible designs

In principle, a toilet in a bathhouse can be of 2 types: mobile (portable) and stationary. If the bathroom is organized in an existing structure, then the first option is more suitable. In a small bathhouse built long ago, all the rooms are clearly laid out according to the required area, where there is no isolated “nook” for the toilet. In this case, lightweight standard partitions are installed and a local container is provided for collecting waste.


For an already built bathhouse without a bathroom, you can use a portable dry toilet, separating it with a partition

A permanent bathroom is included in the construction plan already at the design stage. It has its own permanent walls and door. The sewer drain is formed in advance and ensures the operation of the establishment. The option of an attached stationary toilet is possible, when it is built in close proximity to the bathhouse foundation, and the entrance to it is organized from the bathhouse room.


A stationary toilet must be installed at the bathhouse design stage

Mobile structures include mobile cabins and dry closets. Mobile cabins are made in the form of light partitions, and disposable containers are installed to collect sewage, which are emptied after the bath procedure. One of the common options is a powder closet, or dry toilet. In it, the container is filled with sawdust or peat, which absorb sewage. To clean it outside the bathhouse, a sealed, storage septic tank is built, periodically cleaned by vacuum cleaners. This design does not have a sewer drain, but ventilation must be equipped. For this purpose, a ventilation duct with an exhaust fan is installed. Mobile booths are installed in the dressing room or rest room.


The dry toilet is filled with peat or sawdust

A more expensive, but reliable, modern version of a mobile bathroom is a dry closet. It is a mobile, ready-made stall with a toilet. There is no need to connect sewerage to it, because... Sewage is collected using a two-section container. Sections are arranged vertically. The upper compartment, connected to the toilet and water tank, is equipped with a pump that flushes feces into the lower section.


The lower part with a volume of 10-25 liters is designed to accumulate runoff. This storage tank is equipped with a valve and a pipe for cleaning the container. A chemical-type dry closet uses special reagents that break down solid components and eliminate odors. High-quality dry closets are equipped with tank full indicators. Regardless of the speed of filling the container, the effect of chemical reagents lasts for 12-14 days, after which you will have to clean the container and introduce a new portion of the reagent.


Special reagents are used to care for the dry closet.

The electric dry closet is considered the most effective. It costs more, but does not require the use of chemicals, and the filling cycle lasts much longer. In this design, the lower section is divided into 2 compartments - storage units for the liquid and solid fractions, and drying is carried out in the compartment for collecting solid waste. The liquid fraction, significantly diluted with water, can be sent to the drainage system of the bathhouse.


Features of stationary structures

A stationary bathroom in a bathhouse can be in the form of a separate isolated room inside the building or a small extension on the outside. This toilet is equipped with permanent sewerage and ventilation.

An attached bathroom can be built simultaneously with the construction of the bathhouse itself. In this case, its foundation becomes a continuation of the bathhouse base, and the entrance is organized from inside the building. If the toilet is attached to an existing facility, then it is built directly next to the foundation of the bathhouse. There are several options for logging in:

  • from the inside, when a door is cut through the wall;
  • in the vestibule: in order to connect the toilet and the bathhouse, a vestibule (canopy) is also built;
  • from the street: the entrance to the toilet is located on the street, but in close proximity to the bathhouse entrance.

Photo 1. Plan of a bathhouse with an indoor toilet

The combination of a bathhouse and a bathroom (photo 1 clearly illustrates it) with its internal placement is included in the construction design. There are many standard projects that allow you to implement such an idea with the optimal location of all departments. The fact is that the toilet is a rather specific room, and it should not disturb the comfort of vacationers.

Important condition! For a toilet in a bathhouse, a stationary sewerage system is required.

It can have several options:

  1. A separate storage septic tank outside the bathhouse, into which sewage flows through a pipe by gravity. As a rule, it is located near the bath wall, but is isolated and does not emit odors.
  2. General sewer system. The toilet drain is combined with the bath drain from the steam room and washing compartment if a complete local sewage system with several septic tanks is equipped.
  3. Cesspool. This option is only suitable for an attached bathroom.

To remove sewage from the bathhouse, you can build a septic tank or cesspool

Another important requirement for a permanent indoor toilet is the availability of water to flush the toilet. The flushing system can be organized in the following ways: central water supply; own water supply from a well or borehole; storage capacity.


A stationary toilet must have a flush system

Reset organization

Without solving the issue of collecting and disposing of sewage, it is impossible to create a bathroom in a bathhouse. The most reliable and safest in terms of sanitary standards is the construction of stationary septic tanks outside the bathhouse area. They are sealed wells of the required capacity, in which the discharged mass is accumulated and subsequently pumped out by sewer trucks.

In the toilet itself, a standard connection of the toilet bowl to the sewer pipe is provided using standard elements. Next, the pipe is laid in a trench with a slope to ensure gravity flow of liquid (at least 2 mm per meter of length). The depth of its installation must exceed the depth of winter freezing of the soil.

The sewer pipe is connected to a sealed storage tank. A septic tank, as a rule, is made of reinforced concrete well rings with a diameter of 0.9-1.2 m with reliable waterproofing of the joints on the outside. The bottom of the well is filled with concrete 20-30 cm thick and reinforced with steel rods. The top of the septic tank is covered with a concrete slab with a hole for a hatch.

When constructing an attached toilet, a cesspool is often used for drainage. The main requirement for it is the tightness of the bottom and walls. It can be made by pouring concrete, from sand-lime brick followed by plaster, in the form of a metal or plastic container. The construction of an attached bathroom begins with digging this hole and arranging it. The advantage of this method is that there is no need to lay sewer pipes.

nuance! When planning storage tanks of any design, it should be remembered that feces tend to decompose, releasing substances harmful to the human body.

To eliminate the risk of poisoning, it is necessary to provide a ventilation duct for the outflow of gases from the storage tanks, and the outlet should be raised above the roof of the bathhouse.

Features of the arrangement

The toilet must be protected from the penetration of steam and moisture. Waterproofing a bathroom in a bathhouse is an important condition for its arrangement. During construction, the walls of this room must be covered with a layer of moisture-proof material, which, as a rule, is roofing felt or thick polyethylene film. In addition, it is necessary to provide a vapor barrier, for which a layer of polymer film with foil is laid. In attached toilets, there is also a need for thermal insulation. It is made of mineral wool, polystyrene foam and other materials. A corner bathhouse with a bathroom also requires increased attention, where the likelihood of exposure to moisture from the outside should also be taken into account.


The bath floor must be waterproofed

The most important requirement is the organization of reliable exhaust ventilation. In addition to ventilating storage tanks, it is necessary to remove contaminated air from the bathroom itself. The ventilation riser is installed with access to the bathhouse roof at a height of at least 60 cm above it. The riser should not be located in close proximity to the chimney.

The interior decoration of a bathroom in a bathhouse is no different from the arrangement of toilets in an apartment. Ceramic tiles are recognized as the most common facing material. If there is a bathhouse made of timber with a bathroom, then the interior decoration is most often carried out with clapboard, not forgetting about the formation of ventilation gaps.

Design Features

A bathhouse with a bathroom requires a special approach to design, because... Already at this stage, issues of not only the placement of the toilet on the plan, but also the supply of water supply, organization of sewerage and ventilation should be worked out. There are many standard bathhouse designs that you can safely use on your site. You can choose options for large buildings: a two-story bathhouse with a bathroom or a design for a bathhouse with a bathroom and an attic. In such structures, a certain problem arises with ventilation. Thus, a bathhouse with an attic and a bathroom requires the passage of a ventilation riser through the living space, which requires its reliable insulation and placement along the edge of the attic.

Typical popular projects include the following:

  • 6x6 bathhouse (the design with a bathroom is shown in Fig. 2);
  • a bathhouse made of timber with a toilet (Fig. 3);
  • bathhouse with shower and toilet (Fig. 4).

In large buildings, finding a place for a toilet is not difficult. In such projects, it is important to place it optimally relative to other rooms. Naturally, the greatest need for a bathroom arises after a bath procedure during a period of relaxation in the relaxation room, which must be taken into account. However, the use of the establishment should not interfere with other vacationers.

It is somewhat more difficult to allocate space in small buildings, but standard options are provided for them as well. Thus, 4x5 bathhouse projects with a bathroom and even a 2x6 bathhouse project with a small bathroom are available for implementation. In small bathhouses, mobile options are more often installed, especially when the desire to increase comfort arose after several years of their operation.

A bathhouse with a bathroom is not only a tribute to fashion and prestige. With frequent and year-round bathing procedures, organizing such convenience becomes a necessity. The desire for such a little comfort arises especially acutely when there is a rest room, and also when there are small children in the family. It is best to plan a toilet inside a bathhouse at the design stage, but the problem can be solved in an existing establishment.

Before the log house is erected and the first foundation stone for the bathhouse is laid, the owner must have an understanding of how the bathhouse will be equipped from the inside. What kind of rooms will there be in the bathhouse, how will the partitions in the bathhouse be located, and what will they be made of, what will be the size of the sauna stove and the foundation for it.

And only after this, after a detailed drawing of the bathhouse has been drawn up, order a log house and select a sauna stove.

Partitions in the bath

So, what partitions should be installed in the bathhouse, and between what rooms should they be?

Firstly, a partition between the steam room and the washing compartment. Usually, when a five-walled sauna structure is made, it is the fifth wall of the sauna that plays the role of a partition between the steam room and the sink.

If you ordered a log house with four walls, then you will have to make this partition yourself.

It can be made on the basis of a wooden frame, the cavities of which will be filled. In this case, the wall on the side of the steam room is insulated with a foil vapor barrier, and on the side of the washing compartment - with ordinary waterproofing (any of those commercially available will do).

Basalt wool in the partition will prevent the waterproofing from floating due to high temperatures - it will protect against overheating from the steam room side.

The second number is the partition between the washing compartment and the rest room. This wall inside the bathhouse does not need to be insulated, but only provides good waterproofing. The temperature in the washing compartment and the rest room will be approximately the same - comfortable. And humidity levels vary greatly.

The next option for a partition in a bathhouse is the wall between the dressing room and the rest room. If you don’t have a rest room in your bathhouse, then this will be the case.

If this is a wall between the rest room and the dressing room, you can make it in the form of a simple partition from any available material, and then cover it with decorative panels or decorate it.

If this is a partition between the washing compartment and the dressing room, then it should be protected with waterproofing.

Recently, a separate combustion chamber has often been installed in the bathhouse. This allows you to avoid carrying debris in the form of wood chips and dirt from outdoor shoes into the main rooms inside the bathhouse. The combustion chamber is usually made with a separate entrance - it is adjacent to the steam room in the place where the sauna stove is located.

The partition between the combustion chamber and the steam room is often made of brick or light blocks. The brick wall has a right to exist - it additionally accumulates heat from the sauna stove and then gently releases it. But you shouldn’t make a wall of light blocks in a bathhouse - the blocks absorb moisture well, which, with a difference in temperature in the steam room and the furnace room, will lead to cracking of the blocks and their destruction.

The partition between the steam room and the furnace can be made of brick, or it can be combined - a sheathed frame with cotton wool plus brick.

You can also make this partition based on a frame (preferably from non-combustible materials) filled with basalt wool.

Toilet in the bathhouse

In the rest room or in the washing department, you can allocate a small nook for a toilet. A toilet in a bathhouse is a natural necessity for a modern city dweller. For a long time now, city dwellers have been going to the bathhouse not to wash, but to relax their soul and body by taking bath procedures. And, naturally, he stays in the bathhouse for a long time, sometimes in a large and noisy company.

If you have no desire to relieve yourself in the winter outside the bathhouse wall and in the wind, then it’s time to think about how to arrange a toilet in the bathhouse.

Water for the toilet can be supplied if the bathhouse is constantly heated. Then you can equip the most ordinary water closet and do your business in warmth and comfort. The sauna toilet drain (brown drains) should be separated from the rest of the sauna drain (gray drains) and directed into the general sewer system of the house (septic tank or VOC).

Shower in the bath

If it is possible to connect a water supply to the washing compartment, install a heater, taps with hot and cold water, and shower heads - you will get a modern shower room in a bathhouse.

Only cold water can be supplied from home to the bathhouse shower; water can be heated in the bathhouse itself. About that, read the articles on our website.

You can drain the water from the shower directly into the crushed stone filter, bypassing the septic tank or VOC. The effluent from a bathhouse shower will be “gray”—it will not contain enough BAC to qualify as “brown.”

Installing a stove in a bathhouse

The last item on our list, but not the least important, will be installing a stove in the bathhouse. There is a separate article on the website about choosing sauna stoves and calculating their power.

Here we will dwell more on the process of installing a stove in a bathhouse. It would be good if a separate foundation was equipped for the sauna stove. It can be connected to the general foundation of the bathhouse, if it is capital. And you should not connect the stove foundation with the general one if the bathhouse is built on a small strip or on block pillars.

After purchase, a cast iron or steel stove should be heated outside 1-2 times - this will burn off all the factory dirt that is in any sauna stove after production.

The sauna stove should first be heated - “burned out” - outside, and only then installed in its place in the sauna.

Only after this is it worth installing the sauna stove in its rightful place in the steam room. And only after this can you cut a hole in the roof for the pipe. If you do this in advance, you may make a mistake. Sometimes you see a closed hole in the roof next to a pipe - the result of hasty actions by the owner.
