How to embed a sink into a countertop - we will work for glory. How to properly install a round, ceramic or stone sink into the countertop with your own hands How to install the sink into the countertop yourself
1 Ergonomics in the kitchen
Food preparation should be accurate and fast. This is primarily influenced by the location of kitchen furniture and appliances. In accordance with the principles of ergonomics, kitchen equipment must be arranged depending on the order of work, that is, from left to right: refrigerator, Dishwasher, sink, stove, and between them work surfaces with cabinets.
The minimum distance between individual devices must be:
- 40 cm between refrigerator and sink, as well as between sink and stove,
- 40 cm between refrigerator and stove.
For right-handers, the most convenient is the placement of individual workspaces from right to left. Regarding the sink, this means that the sink should be on the right and the dryer on the left.
It is best if the sink is mounted near the connection to the water supply and sewerage system.
The drainage system at the sink is made of pipes and siphons with a diameter of 40 and 50 mm.
2 Types of sinks
When choosing kitchen sink attention should be paid to the following factors:
- Spaciousness. It determines the number and size of daily washed dishes.
- Functionality. It is determined by the nature of the work carried out in the kitchen, the number of additional bowls in the sink and wings for drying. If you have to carry out several personal manipulations in the sink at the same time, then these compartments will be very useful.
- Ease of use. You should be comfortable standing and working at the sink.
- Stability and durability. These parameters are determined by the material from which the sink is made.
- Combination with the interior of the kitchen. The sink must match the style, design, color scheme and, of course, the size of the entire kitchen.
In terms of installation, there are two main types of sinks:
- superimposed on the kitchen cabinet (overhead),
- built into the kitchen worktop (mortise).
When installing built-in sinks, it is necessary to accurately cut a hole in the countertop for the selected sink. In the case of chipboard, this is not a big problem, but if the countertop is made of stone, conglomerate or composite, then special cutting tools are indispensable. 
MATERIALS USED FOR THE PRODUCTION OF SINKS
Surface-mounted sinks are made of stainless or enameled steel. The two most common finishes for steel sinks are smooth and linen textured.
Mortise sinks are made from stainless steel, mineral epoxy composites and hard plastics.
Composite sinks often have a spectacular grain structure, reminiscent of polished stone. Sinks made of artificial materials can be completely monochrome. This group of kitchen accessories is characterized by its spectacular appearance and high resistance to abrasion, scratches, dents and high temperatures.
WASHING SHAPES
Steel sinks have the widest range of shapes and varieties. In addition to the usual one-bowl sinks, there are sinks with several bowls (usually 2-4), which can be both shallow and deep, with additional side dryers.

4 Installation of a mortise sink
Mortise sinks are designed for installation in kitchen worktops.
The first step is to cut an appropriate hole in the countertop. In countertops made of wood and laminated particle boards, we cut a hole with a jigsaw on wood.
For countertops made of stone, conglomerates or composites, special devices are used when cutting holes, so this service must be ordered at the time of purchase. In this case, it is necessary to indicate the dimensions of the hole and the exact place of installation of the sink. The size of the hole for the sink is obtained by measuring the length and width of the apron on the bottom of the sink.
ATTENTION
The hole should be 0.5 cm wider and longer than the apron.
1. The apron is used for stable installation of the sink. Some sinks come with a sample sink hole that you only need to draw on the countertop.
2. Cut a hole in the countertop with a jigsaw.
3. Insert the seal under the sink, which is included with the sink.
ATTENTION
Wooden and laminated worktops must be protected from moisture after cutting the hole. We cover the edges of the cut hole abundantly with sanitary silicone. After it dries, you can proceed with the installation of the sink.
Steel sinks are fixed in the hole with clamps. The upper part of the mount is attached to the holes drilled in the sink apron. Bottom part rests on the bottom of the tabletop. Both parts are connected with a screw. Tightening the screw, clamp the mount and fix the sink in the hole.
4. After centering the sink in the hole, fasten the first fastener. We do not twist it to the end, leaving a little free.
5. In the same way, we fasten the mount located opposite.
6. In turn, carefully fasten all the fasteners.
7. The last stage of installation is to tighten all the screws in turn so that the sink rests on the countertop with its entire contour.
8. We set the mounting points for the latches in the hole cut in the countertop in accordance with the drawing attached to the product by the sink manufacturer.
9. We screw the clamps into the designated places. They can be from 6 to 12 pieces. 
10. Glue a self-adhesive sealing tape along the edges of the sink, which, depending on the manufacturer, is included in the kit or sold separately.
11. We fix the sink by carefully inserting it into the hole in the countertop. First, the countertop will rest against the edge of the apron on the tabs of the latches.
12. We squeeze the sink in the places where the latches are mounted. The tabs will snap into place in the recesses made on the sink apron. After fixing is completed, you can proceed with the installation of the mixer and the siphon for draining.
ATTENTION
Precise latches and a precisely cut hole ensure that the sink is properly fixed.
The type of sink and its location largely determine the convenience of cooking and the comfort of the entire kitchen. This is not only a functional item, but also part of the design of the room. Therefore, the choice of a kitchen sink must be approached with all responsibility.
We will help you decide on the optimal model and tell you where it is best to place it. We will also describe how to install a sink in the kitchen without the help of specialists. The installation technology is quite simple, the main thing is to adhere to the rules and requirements outlined in the article.
One of key aspects in the installation is the type of sink, which implies a certain design and fastening device:
- mortise- installed in a specially prepared slot in the countertop, cut to the size of the sink;
- invoices- inexpensive and easy-to-install models, superimposed on a free-standing cabinet.
According to the type of location relative to the countertop, kitchen sinks are divided into desktop, undercounter and mounted.
The first is mounted below the level of the work surface. The latter are mounted on hinged brackets, rarely used due to low aesthetics.

Mounting on mounting brackets. In some cases, special fasteners are sold along with the sink. First, self-tapping screws are baited into the inner walls of the cabinet, on which brackets are hung. Then the screws are screwed in ¾. After that, the sink is installed in the opening with mixing on the mounting bracket.
In the process of maneuvering, it is necessary to ensure that the sink is completely pressed against the pedestal, and the self-tapping screw is fixed in the place where the corner is deepened. Then the screws are screwed in until they stop.
Installation of a free-standing sink is somewhat easier, because. implies in its design the presence of special holes and brackets for fixing
Mounting on wooden bars. This method is used when the previous two are not suitable, for example, due to a countertop defect or the lack of appropriate connectors on the sink. In this case, you will need 4 wooden bars and furniture corners. Using these materials, you can make an installation site.
The height of the bars is selected so that the sink is at the same level as the rest kitchen furniture. The bars are cut to the size of the cabinet and fastened with outside with furniture corners. A home-made design is installed on a cabinet and corners with self-tapping screws with inside screwed to the walls of the underframe.
In the last two ways, you need to take care of tightness. To do this, apply a layer of sealant to the contact points of the pedestal / wooden platform with the sink.

Conclusions and useful video on the topic
This video visualizes the process of installing the sink and will help you see some of the subtleties of the wizard.
Mounting the mortise model:
The installation of a sink is a responsible task, on which the functionality of the workspace and reliability depend. Improper installation can lead to the rapid destruction of the countertop if water begins to penetrate under the sink.
The main thing in installation is high-quality sealing of the joint between the sink and the ends of kitchen furniture.

A kitchen renovation cannot be completed until a sink is built into the countertop. In this article, we will introduce you step by step process sink installation in the kitchen: how to make the correct markup, how to cut a hole in the countertop and how to achieve a really competent sink installation.
How the sink is installed
To self installation Washing should only be started if this service is not included in the price list of the countertop manufacturer. At home, it is quite possible to perform such work, but attention should be paid to some non-obvious points that are known only to professional furniture assemblers.
So, the sink is installed in the countertop using the tie-in method. First, a hole is cut in the center of the array according to the exact dimensions, its edges are properly processed. Then the sink is inserted, its body is fixed to the back side with special fasteners, and the gap between the metal and the countertop is carefully sealed. At the end of the installation, the installation of fine plumbing, a sewer siphon or a waste chopper is carried out.
There are three main requirements for installing a sink: fastening strength, tight fit and thorough sealing against moisture. Most often, chipboard with a thickness of 40-60 mm is used as the basis for countertops. This material is very sensitive to high humidity, which is very typical for the washing area. Due to poor-quality installation, the edges of the hole dry out, which may require replacing the entire countertop or even the entire headset.
Marking
The sink should be centered in the middle of the depth of the countertop, offset to the left and right for the most convenient location. The distance from the side of the sink to the edge of the countertop should not be less than 50-70 mm, otherwise the sink should be moved slightly deeper. It is not recommended to indent less than 30-40 mm from the corner plinth, otherwise it will be difficult to wipe the surface in this place. When installing the sink in a corner section, it is useful to leave an indent of 100-140 mm from both walls in order to get a small space for convenient placement of household chemicals and cleaning supplies.
Some manufacturers supply their products with installation templates, some do not. If there is a template, it must be glued to the front side of the countertop, lightly wetting the surface with water. This will help avoid accidental shifting and markup without assistance. The template usually indicates the width of the side of the sink, otherwise it must be measured and marked for visual control of the porch.
If there is no template, the sink must be turned over and installed on the countertop, carefully observing the indents. The sink should be circled with a water-soluble marker and removed, and then shift the contour line inward by the width of the side. If the bowl does not follow the external contours, which occurs in sinks with a drying tray, the marking lines must be shifted a certain distance on each side. If two sinks or a waste compartment are combined in one block, a common hole is cut out under them.
How to quickly and accurately cut a hole for a sink
We note right away that with a household tool you can cut a hole only in a countertop made of chipboard or solid wood, regardless of the type of coating. Stronger materials such as silicon agglomerate require special cutting tools and fixtures.
First, you need to drill several holes in the countertop with a diameter of 10-12 mm at the marking line, but without crossing it. Usually 4 holes are drilled at diametrically opposite points of the contour or at the corners of the rectangle. Drilling must be started from the front side so as not to tear out a large area when the drill exits.
To cut a hole for a sink, you will need an electric jigsaw, on which a file with a width of at least 8 mm and a tooth length of about 1.4-2 mm is installed. It is better to choose the opposite direction of the tooth so that when sawing there are no chips on the front surface. And although the edge of the sink covers a strip of 12-20 mm from the edge, some countertop coatings behave unpredictably and give a rather long crack.
First, a hole is cut on two opposite sides, then a small plank of chipboard or wood is laid across the cut lines. It is attracted by self-tapping screws to the sawn part of the countertop and keeps it from falling when the cut is completed. After installing the bar, you must complete the cutting of the fragment and remove it. An open cut, all chips and unprotected edges are liberally treated with transparent silicone, leaving a layer of at least 0.5 mm, and allowed to dry.
Sink installation and connection
Almost all sinks are equipped with tape seals, but they are quite hygroscopic and accumulate moisture in themselves, creating conditions for the development of mold. Manual sealing with silicone sealant is required instead of standard seals.
With an indent of 1-2 mm from the edge of the hole, a silicone flagellum is squeezed out onto the countertop in a circle, the thickness of which is 2-3 mm more than the height of the sink rim. Another flagellum is applied with an indent of 10 mm from the first. Silicone should be left for 30-40 minutes until its surface stops sticking to the hands. Then the sink is installed in the hole, its edges are carefully pressed down, giving the silicone the desired shape. The sink should be tightly adjacent to the countertop around the entire perimeter, otherwise it may unscrew a little when tightening the fasteners. After 5-10 minutes, the sink must be removed and make sure that the silicone has not burst or spread. Thus, a double continuous edge is formed on the countertop, which excludes the ingress of water inside, while the sink can be easily dismantled.
Before the final installation and fixing of the countertop, it is necessary to mount fittings on it, access to which will be difficult with a bowl, that is, a mixer and an overflow hose, if any. But the siphon or chopper is much more convenient to attach to the installed sink so that it can be held during installation by the open drain hole.
To fix the sink, steel loops are provided in it, located along the contour of the bowl in an amount of 4 to 10 pieces. They are threaded with screw clamps in the form of paws, the edges of which should be oriented outward. After that, the sink is lowered into the hole and finally leveled, then the screws are tightened, firmly pressing the sides to the countertop.
Tricks of professional editing
The main difficulties in installation arise when making a hole: if the gap between the edge of the countertop and the bowl is too large, the tabs of the fasteners may unbend. If the hand is not firm, it is better not to touch the marking line when cutting, and if necessary, adjust the size with a rasp.
When the sink is pressed down, the silicone should not burst. It is better to squeeze a small drop out of the tube in advance and observe how long it takes for a sufficiently strong film to form on the surface.
The mounting screws should not be overtightened, especially with increased clearance. This leads to the fact that the sides of the sink are not pressed, but are bent upwards. A small gap between the side and the countertop can also be sealed with silicone.
Installing the sink in the countertop can be done in several ways, it all depends on the type of sink design and your personal preferences. About all stages of work on self-assembly we will tell further in our article.
Methods for inserting a sink into a countertop
There are several ways to attach a kitchen sink. If it is a consignment note, then it is attached to a pedestal, specially selected for the dimensions of the washing structure. Sometimes when buying kitchen set an integrated sink option can be offered. In this case, the sink and countertop are one-piece construction. Both items are made from the same material by casting, welding or using glue, followed by grinding of all seams to create a perfectly even and holistic design. However, the price will also be quite high.
Most often they resort to inserting a sink into the countertop. This option has gained its popularity, because you can buy a sink made of various materials: plastic, stainless steel, stone, copper, porcelain stoneware, glass, bronze. Among this variety, there really is something to choose depending on financial capabilities. In addition, such structures can also have different shapes: round, triangular, square, etc.
We offer you to familiarize yourself with three possible options for how to embed a sink into a countertop:
- The top edge of the sink is located below the level of the countertop. It is worth noting that this installation method is more inherent in expensive headsets, since the installation cost is high and is done by professionals. These designs look solid and attractive. If you want to do the work yourself, for installation you need to purchase a milling cutter that can make recesses on the inside of the countertop. The surface of the obtained cutters after sawing out is carefully polished and treated with isopropyl alcohol. is made on polymer glue with fixing with clamps for 12 hours. At the final stage, the edges of the sink are poured with a two-component resin, and after it hardens, the front side is ground to achieve a perfect finish. flat surface.
- flush with the table top. Work on the installation of such a sink must be carried out especially carefully and accurately. First, a hole is cut out, and then along the perimeter, strictly measured according to the parameters of the sink, small grooves are made in the countertop as wide as the edge of the sink. After that, all recesses in the surface are treated with sealant. A sink is superimposed on top so that its edges are located in the same plane with the countertop. The design is fixed in the table top with fasteners.
- Sink with edges over countertop. The most common and easiest installation method. The process takes a little time, and what tool is needed for this and the main stages of work, let's take a closer look.
What tool will you need and how to properly markup
Before starting work, you must make sure that the purchased product is complete. For the correct fastening of the structure, together with the sink, special fasteners must be supplied that will help fix the sink in the countertop, and a sealing tape. It can be in the form of a tube or completely flat. Its edges are treated with a special adhesive composition, which contributes to better adhesion of the elements to each other and helps to seal the joint between the sink and the countertop.
Installation work cannot be done without certain tools, the simplest of which are a pencil, a measuring tape (tape measure) and a ruler. You should take care of a screwdriver or a drill with a drill for wood, optimal size which will be 12 mm. You will also need a Phillips and flat screwdriver for the screws that come with the mount, sandpaper and a drywall knife. You also need to take a jigsaw with a set of wood files. To seal the seams and as a waterproofing, we need a sealant.
When purchasing a sealant, give preference to a transparent composition, and pay attention that the product is sanitary - specially designed for "wet" areas.
Installation of sinks can be done both at the stage and later, when the countertop is already installed. For ease of use of the sink and its stability, it is necessary to choose the right place before marking. It is necessary to step back from the edge at least 60 mm, the structure should not be located close to it. The distance from the corner should be more than 3 mm, so as not to create inconvenience during cleaning later. If possible, it is desirable to provide a place for detergents and sponges.
If the sink consists of two blocks, then a common hole will be cut for it, and not individual ones for each bowl. It is important to measure the distance correctly, especially from the inside of the cabinets, so that the edges do not hit the walls of the headset. When the selected model does not provide space for a mixer, the faucet can be installed on either side of the sink, where it will be most comfortable to use, but as close to the countertop as possible.
If a template is included with the washbasin, then there will be no problems delineating the contours of the structure, and you can easily transfer the outline to the surface of the countertop. If there is no template, cut it out yourself from paper or turn the sink upside down and draw its outlines. For convenience, it is better to work together - one holds the structure, the other outlines it. This will help to avoid displacement of the sink during the preparation of the markup. You can also use clamps. Having fixed the structure motionlessly on the countertop, after the contour has been transferred to the surface, you need to step back from its edge inwards a distance equal to the sides of the sink and draw another, smaller contour. As standard, the distance between the two contours will be 12 mm, although depending on the model of the washbasin, this may vary.
Recommendations for cutting a hole and processing a cut
Before you cut the countertop under the sink, you need to check everything again and only then start work. We take a drill or screwdriver with a drill installed on it and make as many holes in the corners of our contour as there are in the sink (4 for square, 3 for rectangular, etc.). For washing round forms, more holes can be made for the convenience of working with a jigsaw on a curved surface. It is important to remember that the holes must be made on the inside of the outline, and their edges should be in contact with the drawn line.
Perform drilling work from the front side of the countertop. So you can avoid large chips and breaks.
After that, we take a jigsaw, insert the canvas into the hole and slowly begin the sawing process. Remember that the hole for the sink must completely match the outlined outline. Even if it is smaller - after cutting out, you can always adjust its size. After finishing work, you need to insert the sink into the prepared hole for trying on. If there is minimal play, then the work is done correctly. The sink should be removed, and the saw cuts should be thoroughly cleaned with sandpaper.
If the countertop is made of wood, chipboard and similar materials, then the saw cuts must be processed, otherwise if water gets on them, the surface will swell, followed by decay, infection with fungus and mold. To do this, after processing the end face with a grinder or sandpaper, you need to apply protective layer, for which you can use PVA glue or waterproof sealant (silicone). Glue is applied to the cut edges with a thick layer and left to dry completely. If use silicone sealant, then it must be applied in such a way that part of the composition falls on the edge of the cut. After carrying out waterproofing work, you can proceed to the direct installation of the sink.
How to embed a sink - the final touches
At the initial stage, you need to degrease the inner edge of the sink and fix the sealing tape on it. We do this not along the very edge, but retreating a short distance. In some designs, you can see that there is a small recess near the side. It is designed to apply silicone. If there is no groove, then it is necessary to apply the composition with a small flagellum between the edge of the sink and the installed sealant. Also, a small amount of silicone must be applied along the edge of the cut out contour, without going beyond its edges.
At the next stage, fasteners must be installed on the inside of the sides, and it is not worth fixing them to the end, otherwise the sink will not be able to pass into the hole. Now you can proceed to the installation of the structure in its place. To do this, the sink begins to be installed in a hole from the side where the tap will be located. The sink fits tightly on the surface until the two surfaces are completely aligned. Part of the sealant applied to the edges of the saw cut should protrude from under the edges of the washbasin, which must be removed before it completely hardens, otherwise it will be difficult to do it later.
Then you need to take the level and check how smoothly the installation was made. If necessary, the sink can be moved a little so that it sits tightly in place. After that, it is allowed to completely fix the fasteners. Do not tighten fasteners with great force. This can cause the edges of the sink to bulge out. After the mortise sink is installed, you can proceed to fixing the plumbing equipment - installing the mixer and siphon.
Times change, and with them, life. Modern kitchen equipment is significantly different from the stereotypes that have developed over the years, only some accessories remain unchanged. Nothing is complete without a refrigerator, sink and stove kitchen room not now, not decades ago. One of the key parts of the “work triangle” is the sink. And if earlier it was, as a rule, an enamelled overhead construction white color, but now the varieties have increased significantly. Modern kitchen sinks are made of various materials, have different shapes, sizes and design features. The installation of such elements may not always be within the power of the owner. Peculiarities different models, their advantages and disadvantages, as well as tips on how to embed the sink into the countertop - further.
Appearance of a kitchen sink, relevant several decades ago
Do-it-yourself sink installation may involve different technologies. Consider the main constructive types of kitchen sinks.
Overhead kitchen sink can have up to two bowls
Types of kitchen sinks:
- Overlay models. This type is considered the most common due to ease of installation. Even a beginner can handle the installation of an overhead sink. They are usually made of stainless steel and are mostly rectangular in shape. Mounted on top of a kitchen cabinet that does not have a countertop.
- Mortise sinks. Such accessories are installed in a prepared hole in the countertop, which must be cut clearly to the size of the structure. The sink is immersed in a hole treated with sealant and fixed with fasteners.
- Underframe products. Their installation method is similar to the previous one: the sink is installed in a hole cut in the countertop. The only difference is that not all countertop materials can provide an integrated installation type, and cuts of the hole must be carefully processed.
The undermount or integrated kitchen sink provides for a complex type of installation and can generally only be done in a factory setting.
One of the important criteria for choosing a sink is its depth. Sink too deep 20 cm or more) is not convenient to use, as it makes you bend over a lot. small bowl ( up to 15 cm) is bad in that water from an open tap knocking on it will spray around the entire working area.
The choice of height of the mixer to a large extent depends on the depth of the bowl. For example, for a deep sink it is better not to choose a faucet with a high location of the spout, as well as for a shallow one with a low one. All this affects usability.
A tall faucet above a deep sink is inconvenient because the water pouring out of it will spray heavily around
Of all the types of sinks listed above, today's users mostly choose the mortise type. Such sinks are affordable, have a comfortable depth and, importantly, modern appearance.

Why mortise: reasons for choosing
The aesthetic component of the kitchen sink is far from the only criterion for choosing a mortise design. Why do modern consumers love this type of sink so much?
The mortise sink can have both a standard siphon and an enlarged hole, which was originally provided for the installation of a dispenser
Design advantages:
- Possibility of installation in any place. By purchasing a mortise-type product, you do not depend on the cabinet installed under it. The bowl can be embedded in any place, the main thing is to bring communications.
- No moisture. When using an overhead construction, it is impossible to hermetically seal the joints between the modules, the washing unit and the walls. Almost always, water flows into the cracks that form, which is fraught with the rapid destruction of furniture and dampness on the walls.
- The choice of mortise sinks is much wider than in the case of overhead sinks. They can have a different form of functionality, the number of bowls, the material of manufacture and sets of additional accessories.
- Modern appearance combined with affordability. The mortise accessory looks almost like an integrated one, but it costs much less.
Mortise sink may include removable cutting boards, nets for washing products and other accessories
Types of kitchen sinks in shape
The shape of the kitchen sink depends on the number of bowls, type and installation location.
Kitchen units are:
- square;
- rectangular;
- round;
- triangular;
- complex shape.
A complex-shaped kitchen sink is made exclusively to order and, as a rule, has a countertop or integrated type of installation.
Washing structures for the kitchen can have not only a different shape, but also the number of bowls. Standard models are usually equipped with one or two bowls, and atypical examples can have up to four.
Example of a round sink with four bowls, a fruit washing net and a cutting board
Video - Do-it-yourself installation of a sink and faucet
Types of sinks according to the material of manufacture
If earlier kitchen sink accessories were traditionally made only of iron, cast iron or stainless steel, then the modern choice of materials is much wider.
Sink made of artificial stone is the second most popular after stainless steel sinks
So, today on the market you can find shells from:
- natural and artificial stone;
- ceramics;
- natural wood;
- faience;
- of stainless steel;
- enamelled metal;
- glass.
Kitchen sink made of faience or ceramics
The easiest to install are stainless steel sinks. Glass sinks are capricious in care, while earthenware sinks are finicky in operation. Sinks made of artificial stone require regular cleaning, and few people can afford granite sinks.
Installation of a mortise sink: step by step instructions
The process of installing a kitchen sink is divided into several stages. Let's consider the installation of a mortise sink in a countertop using the example of a stainless steel product and an MDF surface.
Step 1. Preparation.
The key to successful work is the correct preparation of materials, tools and everything necessary. When purchasing a sink, do not forget to check its complete set for compliance with the description. Often, during transportation and damage to the packaging, small fasteners can be lost. Check if there are enough clips, if there is a seal, etc.
Do not rush to throw away the included sink template. This is a great help when marking the surface.
From the tool for mounting the sink, we need:
- pencil or marker;
- roulette;
- level;
- sandpaper;
- ruler;
- drill;
- jigsaw;
- screwdriver;
- wrench;
- Phillips screwdriver or a set of bits for a screwdriver.
In addition to the sink and its equipment, you will definitely need a colorless silicone sealant and hardware (there are never many of them).
Step 2. Marking.
If there is a template in the kit, the marking is done quite simply: we cut out the outer contour and the inner diameter of the sink from cardboard (on which everything is drawn in full accordance with the dimensions), apply it to the countertop in the right place and circle it with a pencil. To prevent the template from sliding on the glossy tabletop, it can be attached in some places with tape, as shown in the figure below.
Marking on the tabletop using a cardboard template
In the absence of a template, the markup will be somewhat more difficult to perform. First you need to mark the edges of the sink.
Remember! The sink should not be closer to the edge of the countertop than 10-15 cm.
Next, turn the sink upside down with a bowl, lay it on the table as it will be installed, align it parallel to the edges of the table and circle the outer contour. For convenience, the sink can be fixed in some places with adhesive tape.
Outlining the contour, do not rush and fuss. The correct installation of the device will depend on the markup performed.
We measure the distance from the outer rim to the bowl, remove the sink from the markup and draw a cutting line inside the drawn contour.
Step 3. Hole in the countertop.
Using an electric drill, we make several holes in a row along the cut line. The width of the resulting gap should be such that a jigsaw can easily enter it. Next, we take a jigsaw and carefully follow the cut line, slowly and without fussing.

Electric jigsaw
To prevent the cut-out part of the tabletop from falling with a roar to the bottom of the module, fix it in several places with self-tapping screws.
Important! Never flip the table over. Carry out the cut only from its front side so that chips do not form on the enamel.
When the hole is completely cut out, the screws are removed, and the cut is cleaned of dust and sawdust. A “fitting” is carried out: the sink is first placed in the prepared hole, it is checked that it enters normally, does not “walk” and does not cling to anything.
If washing in some place is difficult, trim the cut with a jigsaw
Step 4. Processing the slice.
Any chipboard absorbs moisture well, so the cut point must be carefully sealed with an antifungal compound and glued sealing tape that comes with the sink. Before processing, all roughness must be treated with fine sandpaper. Proper protection of the cut from getting wet will prevent the tabletop material from rotting and its early destruction.
Instead of antifungal compounds for processing the end cut, you can use PVA glue diluted with water in a ratio of 2: 1. After application, the glue must dry.
If chips appear on the front side of the countertop at the cut point on the plastic during the cutting process, treat them with silicone sealant. Only after that it is possible to glue the end cut with the foam sealant that comes with the kit. We also glue the side of the sink along the edge with sealing tape.
Step 5 Attaching the sink to the countertop.
We process the cut of the sink with silicone sealant, attach clips to the sides of the bowl from the inside. We insert the plumbing fixture into a permanent place and press it well on 10-15 seconds. After that, release, check the level, wipe off excess substance soft cloth and wait for the sealant to fully set, fixing the sink in the groove.
It is better to fix the sink with clips after the sealant has set. This method ensures that the sink does not slip off and, as a result, will not be attached incorrectly.
Step 6. Connecting communications.
How a chipboard tabletop is arranged
First, we install the crane, fasten it with a fixing screw. We connect the hoses leading from the tap to the water supply system. When fixing the faucet on the sink, do not forget to use a rubber seal.
On a note. It is better to assemble the mixer even before installing the sink, screwing the water hoses to it. It will also be more convenient to fix it on the bowl with a rhinestone, until it is fixed on the countertop.
For the strength of all connections when installing the pipeline, use fum-tape.
Do not forget to treat all connections with silicone sealant before installing the siphon and faucet

Features of working with artificial stone
As a rule, stone countertops are made to order in accordance with the preferences of the buyer, and a hole for installing a sink in them is provided in advance. But there are also exceptional cases when, for example, it was originally planned to install an overhead sink in the kitchen, and the countertop had to be solid.
A countertop made of artificial stone is quite difficult to process. It must be handled with care as the material is fragile.
For such work, it is better to invite a qualified specialist with a professional tool who will make a hole of the required diameter with a properly processed cut and install the sink in accordance with all requirements.
If you decide to make a hole for installing a sink on your own, saving on workers, instead of a jigsaw, it’s better to take a grinder and protect your eyes and respiratory tract from stone dust when cutting. The algorithm of work is not much different from installing a sink in a countertop made of MDF.
Note. To work with artificial stone on the grinder you need to install a disc on concrete with laser chips.
Features of installing sinks of various shapes and materials
In the example above, we considered a round or oval sink installation. But what about other products?
Corner washbasins
When inserting a corner sink, the main nuance is the cutout of an even corner. To do this, so that the jigsaw passes through the tabletop easily, several holes are made in a row with an electric drill in the corners, then they are combined together.
The presence of technological cuts greatly simplifies the cutout of a hole in the countertop for a sink of an atypical shape.
Also, when installing a corner sink, it is important that the corner of the sink clearly coincides with the line connecting the outer and inner corners of the pedestal.

Square sinks
When installing a square sink, a line is drawn on the countertop parallel to the outer edge. The width of the product recedes from it and another line is drawn. In the same way, two perpendicular lines are measured and outlined, completely drawing the contour of the sink. Opposite corners are connected by lines, at the intersection of these lines there will be a siphon.
Holes for a jigsaw when installing a square sink are made in the corners of the drawing
Granite products
The design of sinks made of natural stone does not provide technological holes for mounting a drain and a mixer. And if the mixer can be mounted on the wall or on the tabletop separately, then the sink simply cannot do without a siphon. It is very difficult to make such a cut in a stone product on your own, without experience. An electric drill with a diamond nozzle is used to make such holes.
In the case of a granite sink, it is better to entrust its installation to professionals, since, without experience, such an expensive product is quite easy to spoil

For the most part, ceramic sinks for the kitchen are made mainly in a combined variety - part of the sink is laid on, and part is mounted on the countertop, like the mortise model.
Ceramics, like a natural stone, has a rather impressive weight, so for such sinks you need a very strong pedestal and a strong countertop
Ceramic sinks are attached in a combined way - for a stronger fixation. Along with the use of sealant or adhesive, mechanical fixing parts are also used. You can also independently prepare the internal supporting structure. To secure the washing niche, a structure is assembled from wooden bars treated with antiseptic compounds.
When making a sink hole yourself, measure the sink several times before you start cutting. It is better to make sure that your actions are correct at the initial stage.
When making a hole for the sink, cut it out, a little short of the markup. Better later sanding a small notch than not knowing what to do with a large one
Experienced installers advise:
- Do not make the sink opening too large. If the structure will "walk" in the groove prepared for it, you can not even dream of the strength of the fasteners.
- Before using silicone, first check how long the substance will harden by applying it to an open surface.
- Do not overtighten the fixing screws when installing the stainless steel sink too tight. This approach may damage the product.
- If a rubber seals was not included - do not rush to the store. They can be replaced with silicone sealant.
- When tightening hardware using a screwdriver, be as careful as possible. By pulling a little, you can bend the structure. If you are not sure that you can calculate your strength correctly, it is better to use a Phillips screwdriver.
Don't skimp on sealant when installing a sink sink. It is better to wipe the excess from the surface with a cloth than to use a leaky design
The most crucial moment when inserting a sink into a countertop is the marking of the surface, and the most difficult is the preparation of the hole. One wrong stroke with a pencil or one misstep with a jigsaw in hand can simply ruin a new countertop. Do not repeat the mistakes of inexperienced masters, but do everything wisely. Successful installation!
