How to cut a countertop for a sink

There are a number of requirements on how to properly install the sink in the countertop. This process must be carried out in accordance with the technology. The choice of the particular installation solution depends on the construction of the sink.

countertop, sink

The following types are the most popular:

  • Overhead products. Considered the most budget-friendly option, which features easy installation of the sink into the countertop. This installation principle is based on the fact that the sink is placed on a freestanding pedestal, making it an extension of the countertop. Sinks of this type have disadvantages. insufficient thickness of the product material and the presence of a gap between them and the countertop, which is inconvenient. Experts recommend choosing an inset sink when there are several separate sections in the kitchen set. If they share a common countertop, the best option would be to use a recessed model.
  • Recessed sinks. The installation of these products is made directly into the countertop. Begin installation work should begin with the preparation of a hole in it. The technology of embedding the sink into the countertop involves attaching the structure to the inside of the module with special brackets and clamps. Recessed models of this type are distinguished by a solid appearance and convenient operation. Despite the fact that they have a high cost, experts with extensive experience prefer them because of their practicality and the ability to prevent the accumulation of moisture between the nightstands.
  • Underbench sinks. The price of these innovative models is so high that it makes them unaffordable for most consumers. The principle of installation of such sanitary ware involves their fixation below the level of the countertop, and therefore they form a single whole with it. Underbench sinks have an aesthetic appearance and good noise absorption. Thanks to effective sealing of joints, these products are characterized by hygiene and durability.

The materials you need

Sealant is used to prevent moisture from entering where the sink and countertop come in contact. Water can severely damage particleboard. Different surfaces require different sealants. Only silicone is used for artificial stone. To wood and plastic more often use sealants containing alcohol.

If it is decided to cut the hole in the countertop under the sink by your own efforts, then you will need a special tool. “angle grinder” with a diamond wheel.

The use of sealant not only prevents unwanted penetration of water. It serves also for additional strength of the connection.

If you buy a sink separately and need to install it, it is advisable to entrust this work to professionals.

  • power drill
  • electric jigsaw
  • wood drill 10 mm in diameter.
  • set of wrenches
  • brush
  • adjustable wrench
  • rasp
  • electric screwdriver

When buying furniture for the kitchen with such a surface, it is desirable to have a ready-made product, which will only require connection to the water supply and sewage system.

Before sawing the hole for the sink in the countertop, you must mark the required holes. For this purpose, from cardboard or thick paper a template is made. Some manufacturers and manufacturers of sinks enclose the template with the product. If you have chosen to install on the countertop and the edges have sufficient width, you can make a marking without a template. For this purpose the sink is used as a template. With its upper surface it is attached to the plane and a marker or a pencil outlines the contour. For convenience of installation it is desirable to remove the tabletop. Step inside 0.5 to 1 cm. from the drawn line, a working contour is drawn, on which the cut is made.

It will look more solid, but it will be more difficult to install the sink yourself into it.

Having marked the kerf line, the template is removed and you can begin the process of sawing out the sinking area. Use a drill to drill a place for the jigsaw blade, about 10 mm in diameter. For a square or triangular washer, holes are made in all corners. If the product has a round or oval shape, one.

Install the sink in a tabletop made of wood or particle board, having the required tools and simple skills to handle it, is not difficult.

The hole and the kerf are made on the side of the laminate, this will prevent it from chipping. Carefully saw out the required hole following the outline drawn with the jigsaw. Electric jigsaw should be pressed tightly to the surface. The saw blade must run straight at a right angle.

The sealing tape that comes with the product is applied to the sink.

When doing this work, support the inside of the part to be sawed out. Or position the tabletop so that when you finish sawing, this part will not fall down. If the remaining and the part to be removed are separated suddenly, the laminate flooring may crack. Or a part of the chipboard is chipped off.

You can use a drill with a special drill bit. furniture drill bit, just take such a drill bit of the required diameter immediately.

If there is no space for such a location, or the tabletop was not removed, use construction tape. In this case, the sawing is done in stages. A cut of 10-15 cm is made., which is then taped on both sides.

To the bowl is mounted drain and, if so designed, a mixer (water faucet).

Once the sawing is completed, the sink is preliminarily tried on. It should fit freely, but the gap should not be large. If it fits too tightly, you should expand the installation site with a rasp or jigsaw.

Having marked the kerf, the template is removed and you can begin the process of sawing out a place for the sink.

Now you should carefully “sand” the inner face, which will be adjacent to the sink. This is done with sandpaper with fine grit. The resulting dust is removed, and a thin layer of sealant is applied to the contact area with a brush.

For the convenience of installation, it is desirable to remove the countertop.

Let’s consider in more detail how to cut the countertop under the sink. The main task to be solved correctly when installing the sink is to observe the geometry of the installation hole in the countertop. At the initial stage, it should be decided which method of installation we will use.

The upper edges of the sink are below the level of the countertop surface. Outwardly, this method looks strict and attractive enough; it is used for expensive sets. When performing it, certain requirements should be observed:

  • you should have special tools, sink of certain shapes;
  • The cut edges of the tabletop must be treated with a water-repellent compound.

Inserting the sink at the same level with the table top. It is important to properly prepare the surface beforehand:

  • The areas that will be in contact with the sink, underwork with a special tool, make recesses equal to the thickness of the sides of your sink,
  • this work is rather complicated, the hole for the sink must be made with great care.

The sink is installed slightly above the countertop level. The method is the easiest and requires no special effort. You can install the sink in this way yourself, having a minimum set of tools.

Marking

  • To proceed to the final installation of the sink, it is necessary to do some mandatory work. First of all it is necessary to measure the pipes and assemble the trap, then holes must be made in the internal structure of the countertop for the sewer and water supply. All these works are performed with a jigsaw or crown. After that the faucet is installed, if a place for it is prepared on the countertop. In addition, if necessary, the hoses are cut. If the faucet will be installed on the sink itself, a place for the equipment is determined on the plumbing fixture and a hole of the required diameter is drilled.
  • Before installing the sink, a sealing tape is put on the sanitary product. it usually comes with the appliance. The tape is fixed near the edge, leaving a special groove free, in which the silicone will be poured. Then the fasteners are installed in their places, which are not pulled out when tightening. they will be fixed firmly after the entire structure will be finally aligned. If the mixer has to be fixed on the sink, it’s turn to install it. The hole is abundantly smeared with silicone, and then the installation of sanitary ware in the hole under the sink is carried out. Before installing the fasteners it is necessary to bend them. To ensure that the sink sits in its place and fits well into the contour of the opening, the sanitary appliance needs to be moved a little. After that you’ll have to climb under the sink and finally tighten the fasteners. While the sealant is in a liquid state, it is wiped off. after some time the composition will set and harden. If there are any gaps, they also need to be sealed with sealant.

How and what is the correct way to cut a hole in the countertop for the sink?

From our article you will learn how to properly cut a hole for the sink in the countertop, what you need to consider and what is better to cut the countertop under the sink.

“To save, so to the full,” reasoned the thoughtful owners. And not only order a budget kitchen, but also plan to cut a hole in the countertop for the sink yourself. True, this operation only at first glance, it seems simple. For a successful result, you need to:

How To Cut a Hole For A Sink In A Laminate Countertop

  • know how to work with this or that material (for example, a quartz countertop will not cause difficulties);
  • Have a set of necessary tools (or know where you can rent it);
  • Understand the nuances, so as not to spoil the product (expert advice is important here).

Only then you can achieve maximum quality and after completing the whole complex of works to enjoy the flawless functioning of the kitchen for many years.

Selecting a sink and preparatory measures

It is not necessary to understand step by step how the installation is performed. There’s also no need to know the exact dimensions. You can probably do without a jigsaw.

But all this will be possible if you ask for help from professionals who will take care of all these issues. But this service isn’t the cheapest, and the price of installation sometimes exceeds the cost of the sink itself. So you can draw your own conclusions. But you’ll have to choose the product yourself. Experts and just experienced home masters advise to opt for a sufficiently deep sink (sink) and not very high selected faucet. Still, the faucet also plays a role in this case.

A deep sink allows you to avoid splashing water, and dirty water, while you’re washing dishes. Plus, a deep product allows you to stack quite a large number of dishes.

Not the least important role is played by the manufacturing material used.

Sinks made of stainless steel are rightly considered the easiest to install. The alternative is enameled steel, but its durability is lower.

To install the sink itself, cut a hole for the faucet, fix it on the countertop under the wood. Made of fiberboard or other materials, you will need to prepare a certain set of tools and materials.

  • Jigsaw. Preferably electric. And buy several interchangeable nozzles at once, because beginners often encounter their breakage due to insecure movements;
  • Self-tapping screws, screwdrivers or screwdrivers. Actually, fasteners and tools for screwing them;
  • Fasteners. Most often, fixtures for sinks and basins are included. Make sure of that when you buy it;
  • Sealant. Be sure to be moisture-resistant, to withstand the further load of water and moisture.

The sealant is applied all around the perimeter of the seating area. That way you will have an effective waterproofing.

If the worktop is made of particleboard or fibreboard, then it is doubly important to use a sealant.

The step by step process of sinking

Preparatory work is quite simple, but it takes quite a lot of time. If you properly mortise the sink into the kitchen cabinet, then there will not be any problems with leaks or swelling of the countertop material.

To get a neat hole, you should adhere to these rules:

  • It is better to use a factory or homemade template for marking.
  • The place of installation should be chosen responsibly. It is desirable to determine in advance where the sink will be installed, in order to properly perform distribution of pipes. It will also allow you to see which elements need to be trimmed. It should be remembered that the supporting elements should not be touched.
  • When using the template, it must be firmly fixed on the countertop so that it does not accidentally move. It will be necessary to cut along the outlined scythe line. When indenting from the contours (if a homemade template is used), the distance to the fasteners must be taken into account. This will make the hole as close as possible to the parameters of the bowl.
  • Some people do not draw the outline when using the bowl template. This is acceptable, but such work is more complicated, so it is worth spending more time and drawing the outline on the countertop.
  • While making a kerf cut, chipping may occur. To avoid this, you can preapply painter’s tape on the contour, which is then easily removed.
  • After completing the sawing, the edges of the hole are machined. It is better to use sandpaper for this.
  • The last step is to treat all the edges with silicone sealant. This material will perfectly protect the cut ends from water, which will not let the countertop start to collapse.

The minimum distance from the wall to the edge of the sink should preferably be 10 cm. This will prevent vulnerable places from getting damaged during the installation.

The position of the sink in the worktop can be selected in several ways. But the basic principle that unites them is to observe the geometry of the bowl and hole. The individual features of a particular model must be taken into account.

sink assembly and connection

Almost all sinks are equipped with band seals, but they are quite hygroscopic and accumulate moisture, creating conditions for the development of mold. Instead of regular seals you need a manual sealing with silicone sealant.

With indentation of 12 mm from edge of an aperture on a tabletop the silicone bundle is extruded along a circle with thickness by 23 mm more than height of a sink edge. Another strip is applied 10 mm away from the first one. Leave the silicone for 30-40 minutes until its surface stops sticking to your hands. Then the sink is installed in the hole, its edges are carefully pressed, giving the silicone the desired shape. The sink must fit snugly against the countertop all around, otherwise it may unscrew slightly when the fasteners are tightened. After 510 minutes the sink must be removed and it must be ensured that the silicone is not burst and does not spill. This creates a double continuous edge on the worktop that prevents water from getting inside and the sink can be easily dismantled.

Before the final installation and fixing of the countertop, it is necessary to mount the fittings, access to which will be hampered by the bowl, that is, the mixer and overflow hose, if any. But it is much more convenient to mount a siphon or a sink sink to the installed sink, so it can be held during installation by the open drain hole.

To fix the sink there are 4 to 10 steel loops located on the contour of the bowl. Screw clamps shaped like feet are inserted into them, the edges of which should be oriented outward. The sink is then lowered into the hole and finally aligned, then the screws are tightened, pressing the rims firmly against the countertop.

To make the right choice, you need to have information, which countertops for the kitchen produce. Options abound: for every taste and wallet. There are simply functional, and there are some that become a decoration of the kitchen. The main criteria for selection are:

  • aesthetic and appearance;
  • waterproofness and moisture resistance;
  • resistance to mechanical damage;
  • compliance with the requirements of hygiene;
  • environmental friendliness;
  • coating resistance;
  • resistance to external factors.

The main and most common materials for the manufacture of countertops are:

Material name Pros Cons
Plastic Affordable price, resistance to temperature fluctuations, easy care, variety of types Looks cheap, if moisture gets inside, there is delamination or bloating, possible toxicity
Wood Good appearance, environmentally friendly, can be arranged in any shape on the worktop, can be easily renovated High cost, need for careful treatment, periodic restoration of the original appearance
Tile Budget option, good appearance, heat resistance, long service life, easy care, environmentally friendly Difficult to care for seams, afraid of heavy objects
Quartz easy care, not afraid of mechanical damage, resistant to temperature differences, hygienic and environmentally friendly, the use of abrasives and detergents for its cleaning, design appeal Difficult to install
Granite Beauty, resistance to big temperatures, not afraid of mechanical damages Imperfect moisture resistance, so need to treat with water repellents, heavy weight, difficult to transport and install, high cost
Marble Hypoallergenic, unique, durable High cost, unstable to temperature changes, the ability to absorb liquid compositions (tea, coffee, juices, etc.).д.), which subsequently leaves stains on the surface, afraid of acidic environment
Glass Does not fear the temperature differences, no need for special care, hygienic, variety of colors and textures High price, afraid of mechanical damages
Concrete Uniqueness, durability, strength, the ability to create different shapes and configurations, color variety, Requires constant care and restoration
Fiberboard Low cost, variety of colors and patterns, exclusivity possible Afraid of temperature changes and mechanical effect, the presence of moisture can cause swelling of the joints
