Installation of a sink and connection of communications

A drain is mounted to the bowl and, if provided by the design, a mixer (water tap). All gaskets are installed in the required sequence. Usually the layout of the gaskets is indicated by the manufacturer on the packaging of the mixer and drain siphon. Threaded connections are well pulled with wrenches or, if necessary, an adjustable wrench.

How To Cut The Countertop Under The Sink

When buying kitchen furniture with such a surface, it is advisable to have a finished product that will only require connection to the water supply and sewerage system.

If there are no holes for water supply and sewerage in the structure on which the installation is planned, they should be cut out. They are done in the same way as for washing. It is drilled with a drill and an electric jigsaw cut out the required opening in size. You can use a drill with a special drill. A furniture crown, just take such a drill of the required diameter right away.

For this, the sink is used as a template.

The sink is fitted with a sealing tape supplied with the product. A small gap is left from the edge, which is subsequently filled with a sealant. Installation of fasteners is in progress.

Some manufacturers and manufacturers of sinks include a template with the product itself.

Reapply the sealant to the contact points and allow it to dry slightly, 2-3 minutes. Install the product in place and stretch the fasteners. Fix the worktop together with it in its place and connect the water supply hoses. Connect the drain. Once again go through the joints with a sealant, the excess must be removed.

Before cutting a hole in the countertop for a sink, the required hole is marked.

Necessary materials

The sealant is used to prevent moisture from entering the places of contact between the sink and the countertop. Water can damage the chipboard badly. Different surfaces have their own sealant. When working with an artificial stone, only silicone is used. Sealants containing alcohol are more often used for wood and plastic.

If you decide to cut a hole in the countertop for a sink on your own, you will need a special tool. A “grinder” with a diamond wheel.

The use of a sealant not only prevents unwanted water ingress. This also serves as additional strength to the connection.

If the sink is purchased separately and needs to be installed, it is advisable to entrust this work to professionals.

  • Electric drill
  • Electric jigsaw
  • Wood drill with a diameter of 10 mm.
  • Set of wrenches
  • Brush
  • Adjustable wrench
  • Rasp
  • Screwdriver

When buying kitchen furniture with such a surface, it is advisable to have a finished product that will only require connection to the water supply and sewerage system.

Before cutting a hole in the countertop for a sink, the required hole is marked. For this, a template is made from cardboard or thick paper. Some manufacturers and manufacturers of sinks include a template with the product itself. If the option for installation on a tabletop was chosen and the sides are of sufficient width, you can markup without a template. For this, the sink is used as a template. The top surface is applied to the plane and is drawn around the contour with a marker or pencil. For ease of installation, it is advisable to remove the tabletop. Having retreated inward 0.5. 1 cm from the drawn line, a working contour is drawn along which the cut is made.

It will look more solid, but it will be more difficult to install a sink in it yourself.

Having marked the cutting line, the template is removed and you can start the process of cutting out the place for washing. A drill is used to drill a place for an electric jigsaw file, with a diameter of about 10 mm. For a rectangular or triangular sink, holes are made in all corners. If the product has a round or oval shape, one will be enough for work.

It is not difficult to install a sink in a wood or chipboard countertop, having the required tool and the simplest handling skills.

The hole and the cut are made from the side of the laminate to prevent chipping. Using a jigsaw, carefully cut out the required hole along the drawn contour. The electric jigsaw must be pressed firmly against the surface. The saw blade should run exactly at right angles.

The sink is fitted with a sealing tape supplied with the product.

While doing this work, the inner part to be cut should be supported. Or position the worktop so that the part does not fall off when you finish cutting. The laminate flooring may crack if the remaining and removable parts are abruptly separated. Or part of the chipboard will break off.

You can use a drill with a special drill. A furniture crown, just take such a drill of the required diameter right away.

If there is no place for such an arrangement, or the tabletop was not removed, use construction tape. Sawing is done in this case with stops. A cut is made for 10-15 cm, which is then glued with tape on both sides.

A drain is mounted to the bowl and, if provided by the design, a mixer (water tap).

After the cutting is completed, the sink is preliminarily tried on. It should fit freely, but the gap should not be large either. If it comes in too tightly, you should expand the installation site with a rasp or jigsaw.

Having marked the cutting line, the template is removed and you can start the process of cutting out the place for washing.

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

For ease of installation, it is advisable to remove the tabletop.

How to cut a sink hole in a worktop?

The furniture manufacturing industry provides a huge number of different kitchen furniture to choose from. Sometimes a dishwasher is offered separately, and is installed by the buyer himself. This does not require any special knowledge and skills.

If the sink is purchased separately and needs to be installed, it is advisable to entrust this work to professionals.

The tool for making the right hole is the simplest one. The question of how to cut a countertop for a sink is not very difficult. However, if you do not follow certain requirements during installation, the installed equipment can be damaged.

The sequence and manipulations carried out are similar to cutting a hole in a chipboard.

The tool for making the right hole is the simplest one.

The place for the cutout is selected taking into account the minimum distance for draining water into the sewer and connecting the water supply.

It is better to do this outdoors, as there will be a lot of dust during the sawing process.

The sink can be installed in relation to the level of the work surface in the following ways.

  1. Below the countertop. This arrangement looks very impressive, but it will additionally require the use of a special tool. The sink itself must have a certain shape. In this case, it is fastened from below, with special fasteners. They are usually sold as a set. The open end must be impregnated with a water-repellent agent. Over, it must have sufficient thickness.
  2. On the same level. In this position, it is very important to correctly make the desired depression, equal to the thickness of the bead. It should be perfect around the entire perimeter of the sink to be installed.
  3. Above the worktop level. The tool for this type of installation is the simplest one. No special effort is required for this installation.

You will need to put on protective gloves on your hands, and protect your face with a special transparent mask-shield.

Installing a sink in a structure made of other materials

It is not difficult to install a sink in a wood or chipboard countertop, having the required tool and the simplest handling skills. A countertop made of artificial or natural stone installed in the cooking area will be more durable. It will look more solid, but it will be more difficult to install a sink in it yourself.

Using a sealant not only prevents unwanted water ingress

When buying kitchen furniture with such a surface, it is advisable to have a finished product that will only require connection to the water supply and sewerage system.

Several ways to insert

Let’s consider in more detail how to cut a countertop for a sink. The main task that should be solved correctly when installing a sink is to maintain the geometry of the hole for installation in the worktop. At the initial stage, you should decide which installation method we will use.

There are several types of installation.

The upper edges of the sink are located below the surface of the countertop. Outwardly, this method looks strict and quite attractive, it is used for expensive headsets. When performing it, certain requirements must be met:

  • You should have special tools, washing of certain forms;
  • The cut edges of the countertop must be treated with a water-repellent compound.

Sink insert flush with the worktop. It is important to properly pre-prepare the surface:

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

The sink is installed several above the table top. The method is the simplest and does not require much effort. You can install the sink in this way yourself, with a minimum set of tools.

How to cut a countertop for a sink

Equipping a countertop with a sink is a rather difficult task. If you do not follow the established installation requirements, you can damage both the equipment itself and the covering of your table in the kitchen.

How to do such work yourself

For example, consider the installation of washing equipment in a chipboard worktop. Installation type. Above the table surface. The entire workflow can be decomposed into the following stages:

  • Marking of the future hole;
  • Cutting a hole;
  • Installation of a sink;
  • Sealing of docking points.

Work should begin with the preparation of the necessary tools. Make sure that all necessary hardware is supplied with your sink. From the tools you will need:

  • Construction pencil;
  • Level, corner and tape measure;
  • Drill and drill for woodwork;
  • Screwdriver;
  • Electric jigsaw;
  • Silicone and self-tapping screws.

You can get to work. Make sure that no foreign objects get in your way. It is advisable that the tabletop is not fixed to the pedestal frame. If the table is already assembled, it doesn’t matter, you can cut a hole like that. We carefully carry out the markup. Consider how this is done for a rectangular sink:

  • With a construction pencil, draw two mowing lines perpendicular to each other. There will be a drain hole at the intersection.
  • Turn the sink over, lay it on the countertop and outline its contour. At the same time, do not forget to take into account the level of the sink edge relative to the table doors.
  • We measure the width of the sink rim and draw the inner contour. The cutting will be done along this line.
  • We double-check all the parameters and proceed to cutting.

You need to cut the hole with an electric jigsaw. To insert the file, you need to drill technological holes in the tabletop. Usually they are performed with a drill at the corners of the contour. All drilling work is done on the face of the worktop. This will make it possible to do the job without any kind of chipping of the laminated sections of the table. Now you can take a jigsaw and cut a hole along the inner contour. After that, you should first try on your sink to the hole obtained.

Now you need to clean the edges of the hole. This is necessary so that the uneven edges do not interfere with high-quality sealing of the joints. This work is done with fine-grain sandpaper. After stripping, we perform sealing. In this case, you can use two methods:

  1. Sealant.
  2. PVA glue.

The first method is good, but it should be done with great care so as not to miss sections of the countertop. Best of all, if you do not regret the sealant and apply it with a decent margin. The second method is more difficult. PVA glue should dry for almost an hour. But it reliably protects against moisture penetration.

How to install a sink in a worktop: a simple algorithm

Hello, friends.

In this article, we will consider one very serious operation, which greatly affects the quality of the kitchen set.

It’s about the sink sidebar. We will look at this whole process from start to finish with all its nuances.

Before you embed the sink, you need to decide in which part of the countertop it should be located.

To do this, the countertop must be placed on the lower modules of the kitchen, and the box in which the sink should be placed, from the inside, circle it with a pencil (along the countertop) to determine the internal space for it.

After that, the table must be put upside down, and mark the place for cutting the hole. This is done as follows:

First, the location of the sink itself is determined (it should not go beyond the inner border of the box, otherwise, to insert it, it will be necessary to cut not only the countertop, but also the sides of the box

  • When the position is determined, it is outlined with a pencil along its contour
  • Then, with a tape measure, you need to measure the distance from the edge to the ear, into which the fasteners are attached
  • After that, in case the sink is round, the center of the drawn circle is located. It is located as follows: on the circle, in any place, a point is placed to which a straight part or ruler is attached. To this straight line, you need to attach another part (or a square) with a right angle. In the area of ​​the center, a line is drawn. Then the second point is taken and the same is done. The intersection of two lines will be the center of the drawn circle (yes, sometimes knowledge of geometry can be very useful)
  • Mowing lines (type, diameters) are drawn through the center of the circle. They are needed in order for them, from the edge of the circle, to measure the distance we measured from the edge of the sink to its ear for fasteners.
  • Having made 8-10 such “serifs”, through them, using the same sink, we draw curves (in parts), which form inside the circle we have drawn, another circle, the radius of which is less than the radius of the main circle at the distance from the edge of the sink to its ear. This will be the circle that you need to cut with a jigsaw.
  • We make a hole on the inside of this circle with a large drill (usually, this is a drill with a diameter of 10 millimeters).
  • We insert a jigsaw file into this drill, and cut a hole. Do not forget, when the hole is almost cut, support the cut out part of the countertop, as it can break off, breaking the plastic from the front part.

When the hole is made, the inside of it needs to be covered with silicone, since this place is the most problematic place in the kitchen. It should be protected as much as possible from moisture getting inside the countertop, since in this case, the countertop can simply “break” from moisture. And this is its complete replacement.

So, after the hole is “siliconized”, we begin to prepare the sink for the insert.

To do this, you need to stick adhesive tape on its inner surface, which is always included in the kit (plus fasteners and plus, plastic pipes for draining).

Pay attention before buying a sink: The adhesive tape (which needs to be glued inside), should not be stuck on it. It should be included. Almost all sinks in which adhesive tape was previously glued, it was not glued correctly.

And correctly, it is glued so that there would be a small distance between it and the side of the sink itself (it turns out there, like a gutter), where the silicone is poured.

It turns out at the same time, two barriers: adhesive tape and silicone.

So, when all this is done, and the silicone is poured, the sink is inserted into the hole cut in the countertop (from bottom to top). If the tabletop is located, for example, on two chairs, then one of them can be immediately substituted under the sink, thus fixing it.

After that, fasteners are inserted into it.

I want to note that this is one of the most unpleasant moments when installing a kitchen unit.

The fasteners that attach it to the countertop are usually poor (meaning, poorly thought out). There are almost always problems with it (for this, you need to always have spare versions of this fastener for installation).

There are situations when he simply does not fix the countertop, but climbs to the sink (which happened at the installation, the graphs from which are laid out in this article as an example).

As we did not bend the antennae of the fastener itself, he stubbornly jumped off the tabletop (and, of course, did not fix it).

The easiest way out of this situation is as shown in the figures: you need to insert a piece of chipboard, or something else, between the sink and the fasteners themselves. Thus, the fasteners are fixed and, by twisting, attracts the sink.

But, do not forget one detail: you need to exercise with the installation, if possible, not very long, since the silicone that was poured into the sink, when pressed against the countertop, partially “crawled” out. It should not have time to freeze, because in this case, removing it, you can remove part of the silicone under the sink.

When it is pulled against the worktop, you need to make sure that there are no gaps between it and the worktop. If they are, then it is badly attracted.

At the end of the insert, you need to wipe the silicone protruding from under the sink and the sink itself.

That, in general, is all.

This is where I end up, see you in new articles.

Stage # 3. Edge treatment with silicone gel

The end surfaces of the resulting hole are sanded with a file and emery paper. After alignment, these places are lubricated with silicone sealant. Over, this manipulation must be performed with special care, thus, it will be possible to avoid problems with leaks when using the sink.

The edges of the cutout must be carefully sealed

The sealant must be designed specifically for the material from which the countertop is made. If it is wooden or plastic, then the sealant should be alcohol-based.

Once the ends are filled with silicone, it’s time to insert the sink into the countertop. The fit should be very tight, if necessary, the product can be turned.

Now all that remains is to install the sink in the countertop

The installed fasteners are now tightened. The silicone that will be squeezed out in some amount when the sink is planted must be removed. The structure must be left to dry. Everything, we can assume that the sink under the countertop is finally mounted. But this is not the end of all the work, because the drain fittings have yet to be connected.

What tools will be required for the job?

To do this work, nothing special is needed, all these items are always in the household:

  • Jigsaw or hacksaw;
  • Drill;
  • Screwdriver;
  • Pliers;
  • Clamps;
  • Spatula, brush;
  • Sealant.

To the same list it is worth adding: a ruler, a pencil, a rag.

Stage # 4. Final assembly of all elements

Installation of the mixer requires great care and meticulousness. Although if a hole for a mixer is made in the sink at the production stage, then there will be no particular trouble. If there is none, it means that you will have to make this hole in the canvas of the countertop.

Naturally, this procedure is carried out even during the period when holes are cut out for mounting the sink. Hoses are installed in the mixer, then the product is inserted into the hole of the sink and fixed with special fasteners.

Self-installation of the sink in the countertop. Analysis of the installation technology

Setting up your own home is a creative process that has almost no end. To create the perfect home, you have to invest a lot in the implementation of your creative ideas. Although you can always try to reduce them by doing some work without outside help. For example, with the right approach, self-installation of the sink in the countertop will not be a daunting task. It is even interesting to combine two independent faceless objects into a single logical composition with your own hands.

Installation sequence for a recessed sink

By far the most interesting is the detailed consideration of how to install a sink in a fully recessed countertop. In principle, there is nothing incomprehensible in this procedure, it is not divided into several stages:

Stage # 1. Marking the installation site

The correct marking will be ensured by the template that comes with the sink

The place where the sink for the bathroom with the countertop will be installed is determined. In this case, three conditions must be met:

  • The sink cannot be located right next to the wall;
  • The sink should not be at the very edge
  • The paramount must be on absolute usability.

So, the meaning of this work is that the sink should not fall into the created hole, but it must be firmly and conveniently placed on the countertop. The sink under the countertop is turned over and laid on the surface. The outline is outlined. For this, a pencil is used that is easily erased. Then measurements are taken to determine the distance from the lugs of the fasteners to the edge of the sink.

The resulting dimension determines the distance that deviates from the mowing line of the previously outlined contour inward. Based on the dimensions obtained, a new marking of the inner contour is performed. You can do it even easier: just step back 1.5 cm along the entire outline inside the outline and draw a new reduced outline. Even a person without artistic talent will perform these simple actions correctly. But the resulting inner “figure” is to be cut out.

And if such assistance is not provided by the manufacturer, then you need to act according to the technology described above.

Stage # 2. Cutting along the outlined contour

Cutting a hole with a jigsaw will turn out faster and more accurately

Before the undercounter sink is installed, a hole is prepared. For cutting, ideally, you need to have a jigsaw on hand. Although you can use a simple hacksaw, but then you have to trim the edges. If a hacksaw is used, a hole is first drilled inside the outlined contour close to the mowing line of the marking. It should be large enough to fit the hacksaw blade. Then the unnecessary part is carefully cut out. In this case, it is necessary to minimize the pressure on the decorative coating of the countertop, since when performing this work, chips may appear.

Option # 2. Overhead sink

The installed sink on the countertop is a new word in the arrangement of the bathroom. In this case, the product is simply placed on the countertop, and any flat surface can play its role. Naturally, many special countertops are offered for sale; they differ from the usual ones in that they have recesses.

This sink installation has both pros and cons. So, due to the absence of joints, problems with water leakage are eliminated, and accessories and accessories can be stored on the surface of the countertop. Such a structure can be easily placed over the washing machine. The pipe is fed to the sink in the same way as to the flat wall-mounted sink.
