Types of products and installation methods
There are several options for installing a sink into a countertop. The choice of installation method depends on the design features of the sink. The most common types of sinks are:
| Types of products | Advantages | Flaws | Installation principle |
| Invoices | Budget price category. Easy to install. | Small material thickness. Formation of a gap between the countertop and the sink. | The sink is placed on a free-standing cabinet so that it becomes an extension of the worktop in the kitchen. |
| Mortise | Ease of use. Practicality and durability. | High price. | Inserting the sink into the countertop, into a specially made hole, provides for fastening with clamps and brackets to the inside of the module. |
| Under-desk | Aesthetic appearance. Noise insulation. Durability due to reliable sealing of joints. | Inaccessible due to high cost. Not suitable for all countertop materials. | The sinks are mounted in a cut-out hole, but are fixed below the countertop, forming a single whole with it. |

Kitchen sinks are traditionally made from stainless or enameled steel, as well as from artificial stone and composite materials, which are resistant to external influences and sudden temperature changes.
Under-table mounting
This method implies that the countertop will be higher than the edges of the sink. The installation method is used for furniture made from expensive materials. This allows you to achieve an attractive, sophisticated and strict look.
To perform such an installation, you need to buy a special sink designed for under-table installation. The sink is secured with screws or brackets.
In the case of the most expensive products, special self-tapping screws are included.
A special tool is usually used to cut a hole in the tabletop, but you can also use a regular jigsaw with diamond blades. The edges must be sanded and impregnated with moisture-repellent agents or covered with a special film.
Without the skills to perform such work, it is quite difficult to install an undermount sink. It is advisable to call a professional.
Please note the following during installation:
- You need to buy an undermount sink and the tools to install it.
- If you make a mistake when cutting a hole, the tabletop will most likely be damaged. After this, only the countertop sink can be installed.
The simplest method of installing such a model involves cutting the hole from the inside. The main thing is not to make mistakes in measurements. The sides of the kitchen sink should be flush with the opening. It is unacceptable for them to protrude or relapse.
How to install a countertop sink
The method of installing overhead products has its own peculiarities. The sink is mounted on a separate kitchen module so that its upper part is completely covered. This work is usually not difficult even for beginners. The sink is fixed using L-shaped elements with oblique slots.
Before installing an overhead stainless steel sink on the cabinet, you need to complete the following preparations:
- Purchase at least 4-5 parts for fastening, as well as 15 mm self-tapping screws.
- Connect the mixer in advance.
Instructions for installing an overhead sink:
- Take the prepared fasteners. Attach them to the inner surface of the cabinet. Place marks.
- Focusing on the markings, tighten the screws. They should be located 5 mm above the markings.

Treat the end part of the cabinet with sealant. This will make the sink mounting location more reliable and protect it from moisture and dirt.
Place the product on the screws. Before attaching a stainless steel sink to the countertop, you need to check that it fits as tightly as possible to the cabinet.
Fasten the fasteners firmly. If excess sealant appears, clean it from the cabinet. Connect the water supply.

Mounting a mortise sink
Inserting a sink into a countertop involves a number of successive steps.
Preparing materials and tools
Before proceeding with the installation of the sink, check the complete set of the sanitary ware. The kit must contain all the necessary fasteners and seals. You should have on hand: silicone sealant, tape measure, level, Phillips screwdriver, screwdriver, electric jigsaw, drill.
Carrying out markings
The method of applying markings on the tabletop depends on whether the kit includes a cardboard template. Its presence greatly simplifies the work. The outer and inner contours of the sink are cut out using the template. Then it is placed on the tabletop, secured with tape and outlined with a pencil.

If the template is not included, marking the hole is a little more difficult. First, trace the edges of the sink, positioning the sink so that its bowl faces down. Then the sink is turned over and placed on top of the countertop in the same way as it will be installed when finished. Secure with tape. Align and trace the outline. The correct installation of the product and the ease of its operation depend on how accurately the markings are made. A cutting line is drawn inside the contour.

Cutting a hole
Before cutting a hole for the sink in the countertop, take an electric drill and make 2-3 holes one after another on the cutting line to create a single gap. Its length should be such that an electric jigsaw can easily fit inside. With its help, slowly and very carefully cut out a hole.
If the jigsaw deviates a little from the marking line, it’s okay. A discrepancy of 2-3 mm is allowed. The cut site is cleaned of dust and the product is “tried on”. It should fit freely into the hole, but not cling or “walk around”. If the shell does not fit completely into the hole, it is slightly widened using a jigsaw.

How to embed a sink into a countertop with your own hands?
How to properly and easily embed a sink into a countertop? This question is faced by everyone who has started renovating their kitchen. We will tell you clearly and in detail how to do the installation competently and quickly.
How to install a sink into a countertop?
Often, the installation of the sink is carried out by the manufacturer. But it happens that this service is not listed in the price list. Then this concern falls on your shoulders. But don't worry. You can install the sink yourself, armed with the necessary tools and advice from professionals.
Installing a sink involves several stages. At the initial stage, you must make a hole in the middle of the array, then process the edges. The next stage is inserting the sink, fastening its back side and sealing the distance between the countertop canvas and the sink. The final stage is the supply of water supply and sewerage communications.
The key to a high-quality sink installation is: reliable fastenings, sufficient fit and high-quality sealing. Moisture is a fairly aggressive factor affecting the kitchen countertop, especially if it is made of chipboard. High-quality installation will prevent the tabletop from drying out or swelling, which will extend its service life many times over.

Performing markup
This is quite an important stage. Place the sink in the center of the countertop. Remember that the gap from the edge of the countertop to the side of the sink must exceed 50 mm. If this distance is less than 50 cm, then the sink needs to be deepened.
The distance from the corner plinth should be more than 30 mm so as not to create problems during cleaning. If the dimensions of the countertop allow, then it is better to leave a little space on both sides for household chemicals and a sponge.
If the manufacturer provides a template for inserting the sink, then the task is much simpler. The template is glued to the tabletop and makes marking easier.
If the countertop does not have a template, you should install the sink on it, upside down, and trace along the contours with a washable marker. If there is a sink and a drying compartment or waste tray in one block, then one common hole is cut out.
How to make a hole for a sink?
To make a hole in the tabletop you will need an electric jigsaw. It is suitable for countertops made of wood and chipboard. If the countertop is made of durable materials, then a jigsaw will not cope. First, prepare 4 holes with a diameter of 1 cm in the corners of the rectangle, without crossing the marking line. Then a file with the required tooth length (2 mm) is put on the jigsaw. To avoid chipping on the front surface, choose the opposite direction of the tooth.

Holes are made on the left and right, and then the wooden plank is pulled in with self-tapping screws across the sawn lines so that the cut part does not fall prematurely under the force of gravity. The cut out part is carefully removed, and the exposed edges of the hole and irregularities are coated with liquid silicone.
Installation of sink and connection of communications
Here again you will need liquid silicone. Stepping back a couple of millimeters from the edge of the hole, we apply the silicone in a thickness just above the side of the sink. Stepping back from the first one another centimeter, we apply another flagellum.
After half an hour, the silicone will dry and stop sticking to your hands. Then you need to insert the sink into the hole and firmly press the edges so that the silicone strands take the shape of the sink, and leave for a few minutes. Then the sink is removed and the silicone is checked. If it is not broken, then everything is in order, and the sink will have a reliable additional side.
We attach fittings to the countertop to install the mixer and hose. It is more convenient to attach the siphon to an installed sink. Many sinks have special loops for screw clamps in the shape of the claws. They help tighten the sides to the tabletop more tightly.

Tips from the professionals
The most difficult thing is to make the hole correctly. If it turns out to be larger than expected, the paws will not be able to hold the sink. Saw out the hole, just short of the marking, and if the sink doesn’t fit, a rasp will help you adjust the hole to size.
Different silicones harden differently. Before pressing down the edges of the sink, check how long it takes to tighten the drop in minutes. If you rush, the silicone may burst.
Do not tighten the screws too tightly. Otherwise, the sides of the sink will bend upward.

Connecting communications
At the final stage, communications, cold and hot water are supplied to the plumbing product. First, use a fixing screw and a rubber seal to secure the tap. Experienced craftsmen assemble the faucet before cutting out the countertop for the sink, connect hoses to it and fix it to the bowl.
Water hoses are pulled to the water supply system. Check the reliability of all connections. If necessary, use fum tape. Start the siphon and connect it to the drain corrugation.

Professional advice on installing sinks: what to look for
Experienced installers share the following secrets of their work:
- When installing a mortise sink yourself, you need to check the dimensions of the hole several times. It should not be too large, otherwise the sink will “walk” in the groove and the fastenings will not provide the required strength.
- When installing a stainless steel sink, do not overtighten the screws. This may cause damage.
- Instead of the seals that come with the sink, you can use sealant. You shouldn't save it. It’s easier to carefully remove excess than to deal with leaks later.
- When using a screwdriver, it is important to be careful not to bend the hardware. If you don’t have much experience with this tool, you should give preference to a Phillips screwdriver.

Necessary materials
Before work, you need to prepare a number of materials and tools that are used when installing sinks:
- jigsaw;
- drill with attachments;
- square, ruler, pencil;
- furniture corner, special fasteners for sinks, if they are not included in the delivery package;
- sealant (it is better to take transparent silicone);
- seal for sinks.
When purchasing, unpack the product, check the integrity of the bowl and sides, determine the completeness of the product and the need to purchase the necessary parts. In addition to the fasteners, during installation you will need a siphon and a pipe connecting to the sewer (ready-made kits), fittings in the form of a mixer and connections to it.
Installation features depending on the shape and material of the sink
The insertion process may have its own nuances depending on the selected sink material and its shape.
Installing a corner sink
An important point when installing such a product is cutting out a right angle. In order for an electric jigsaw to easily pass through the corners of the tabletop, several holes are first made in them with a drill, one after another, and they are combined.
You should also pay attention to the fact that the corners of the sink and the connection lines between the inner and outer corners of the cabinet coincide.
Installing a square sink
Installing a sink into a countertop begins with drawing a line that runs parallel to the edge of the countertop. Then make an indent to the width of the sink and draw a second line. In a similar way, two perpendiculars are measured and laid.
Mark the intersection point of the segments that connect opposite angles. The siphon is located in this place.

Installing a stone sink
Sinks made from natural stone, such as granite, do not have faucet or drain holes. The first can be mounted separately to a tabletop or adjacent wall. And it is impossible to do without a siphon.
Carefully making such a hole in a natural stone sink yourself, without sufficient knowledge and experience, is a very difficult task. For this you need an electric drill with diamond bits. For this reason, it is better not to install expensive granite sinks yourself, but to trust specialists.
Step-by-step tapping process
The preparatory work is quite simple, but it takes quite a lot of time. If you properly embed the sink into the kitchen cabinet, then there will be no problems with leaks or swelling of the countertop material.
To get a neat hole you should follow these rules:
- For marking, it is better to use a factory or homemade template.
- You should take a responsible approach to choosing the installation location. It is advisable to decide in advance where the sink will be installed in order to correctly install the pipes. This will also allow you to see which elements need to be trimmed. It should be remembered that the load-bearing elements cannot be touched.
- When using a template, it must be firmly secured to the tabletop so that it does not accidentally move. You will need to cut along the drawn line. When indenting from the contours (if a homemade template is used), the distance to the fasteners must be taken into account. This will allow you to make a hole as close as possible to the parameters of the bowl.
- Some people don't draw the outline when using the bowl template. This is acceptable, but such work is more complex, so it is worth spending more time and drawing an outline on the countertop.
- While making a cut along the cutting line, chips may occur. To avoid this, you can stick masking tape along the contour in advance, which can then be easily removed.
- After cutting is completed, the edges of the hole are processed. For this it is better to use sandpaper.
- At the last stage, it is necessary to treat all edges with silicone sealant. This material will perfectly protect the cut ends from water, which will prevent the tabletop from starting to collapse.
It is advisable to make the minimum distance from the wall to the edge of the sink 10 cm. This will prevent vulnerable areas from being damaged during installation.
The location of the sink in the countertop can be chosen in several ways. But the basic principle that unites them is to respect the geometry of the bowl and hole. It is imperative to take into account the individual characteristics of a particular model.

We install ceramic products
Ceramic sinks have the following feature: one part of the sink is overhead, the other is cut into the countertop. Such models are fastened using a combined method. To ensure the reliability of the structure, both sealant and mechanical fixing devices are used.
In addition, to secure the sink, load-bearing structures are made from wooden blocks. You can do this yourself. Wood should be treated with antiseptic agents.
