How to cut a hole in a ceramic sink

Repairing a ceramic sink: how to fix a chip or crack, how to drill a hole

Sinks made of artificial stone do not always have a special cutout, so there is a need to make a hole in the sink yourself. A common obstacle is the fear of damaging or crumbling the sink. Although similar to natural stone in its properties, it is in fact more like plastic: or, better said, a polymer mass mixed with crumbles of stone.

The ratio of the amount of resin to stone chips can vary greatly. Regardless of the proportions, this material is better to drill than stone. However, you should still be careful and cautious. The sink made of artificial stone requires careful attitude: it is not recommended to carry out any work until its temperature is equal to room temperature.

How to drill a hole in artificial stone

Usually the sinks made of artificial stone are supplied with a hole for the mixer, but it is possible that without it, or you need to drill an additional hole for the water filter. What to do in such cases?

You can resort to the help of specialists, but if you feel confident, you can try to drill the hole yourself. But it is necessary to determine the material of the product. this determines what tool to use.

Porcelain stoneware

The strongest and most durable of the whole group. porcelain stoneware. It serves long and durable, tolerates temperature and chemical influences well, that is why it is in great demand. But it is also the most difficult material, it is more difficult to make a hole than other types of artificial stone.

The best option for carrying out the work is to choose a crown for porcelain stoneware. It can be supplied in a set with or without a centering drill.

During work with porcelain stoneware the place of drilling must be constantly cooled down, and the speed of the drill must be at its lowest rpm.

You need to understand which side to drill from and when. If on the front side, after installation, the edges of the hole will turn out even and neat, but there is a danger that the drill will slip and spoil the look, for example, scratch or damage the edge.

If the back side, before installation, it is unlikely to damage the bowl, but it is possible that the hole will have rough edges. Mostly it’s no big deal, because they will be covered by the faucet.

Remember. the farther the hole from the edge of the product. the better. Do not forget about the bowl, so as not to get another, completely unnecessary hole. porcelain stoneware is both strong and very fragile material. Therefore, it is necessary to observe the following rules:

  • Before carrying out the process, fix the sink, put particle board underneath, this will protect the work surface.
  • Drill exactly perpendicularly, otherwise the drill can damage the glaze.
  • To prevent the drill from shifting, the area where you will be drilling, seal the area with masking tape.
  • Wet the drill bit before working, while drilling. sprinkle the place of work with water, for example from a plastic bottle.


Cutter for working with artificial stone

Agglomerate is a softer material. There is usually a nearly pre-drilled hole already on the basin. It needs to be knocked out with a core or drilled out with the router that comes with the sink. If the kit is not enough cutter or core, it is necessary to do the work with a diamond drill bit. The instructions are exactly the same as for drilling porcelain stoneware.


The third option is acrylic. If your sink and countertop have color unity and are a one-piece space, it is acrylic stone. This option is not difficult to work with. Regular drills for work with metal or wood will do. Diameter of the hole under the mixer is 32-35 mm. It can be drilled with a feather drill bit to work with wood. The speed of the drill should be at medium to low speed. When working with acrylic stone, a lot of chips are formed, and from the heated plastic drill bit there is a rather unpleasant smell.

How to work with a stainless steel sink

Often, manufacturers make stainless steel sinks without a hole to accommodate a faucet. As a rule, these sinks are made of solid steel. It is very difficult to drill this sink with an ordinary drill bit. A diamond-coated drill bit is barely enough for one hole (after that, it’s just a highway to the garbage).

For your consideration we offer several variants of how to make a hole for mounting a faucet on a stainless steel sink, though these tips are universal and will work for a sink made of ordinary steel.


To drill a hole in it, you need to use cobalt drills (or tungsten, but they are more expensive) and a punching tool. A punching tool is a tool made of two parts. It consists of a die and a knife, connected with a bolt.

The sink has to be turned upside down before you start. Then follow the following order of action:

Mark the place of installation of the faucet with a pencil or bright marker. 2. In the center of the circle nakernivaem a small indentation, so that the drill does not slip. 3. We make an initial hole with a 5-6 mm drill, and increase it with a drill of appropriate diameter to 10 mm. 4. Install the puncher (punching tool) so that part of the smaller diameter is where the faucet should be. Tighten the bolt until the tapping block cuts a hole.


The second option involves drilling holes only for flexible liners and mounting stud(s). You can use the faucet clamping strip as a template. This option saves you the trouble of buying a nailing gun. But in any case you cannot do without cobalt drills.

Best answers

The same way you drill glass: Around the place of drilling make a ring of plasticine and pour acetone in it, then a simple drill at low speed drill, gradually pouring acetone to the desired level. The difficulty is that the hole is larger than 10 mm. it’s hard to do.

Why drill it?? But with a concrete or glass drill, you can. Just be careful with the diamond wheel

And you have to drill very carefully. Not forgetting that the basin is two layers and the foot is one layer

with a pobedite drill bit, just tape the drill spot down

Use a copper tube of the right diameter, sprinkle with sandpaper and liquid.

Takes a drill bit (diamond. the right diameter) in the drill, at low speed, with water spraying, though first you need to stead the CONDUCTOR out of the tiles, at the same time and will practice. then you put the conductor on the sink, preferably a flat surface, fasten the conductor with tape and drill with water

Do not listen to anyone, but “without impact” of course

Tape the hole with a self-tapping screw. Drill with a simple 6mm drill bit without impact.

Mounting the sink

Fitting the sink into the countertop includes a number of consecutive steps.

Prepare materials and tools

Before proceeding to install the sink, check the completeness of the sanitary product. In the kit must be present all the necessary fasteners, seals. At hand should have: silicone sealant, tape measure, level, Phillips screwdriver, electric screwdriver, jigsaw, drill.

Execute layout

The way of drawing the marking on the countertop depends on whether there is a cardboard template in the kit. Its presence greatly simplifies the work. Using the template, cut out the outer and inner contours of the sink. Then they put it on the countertop, fix it with tape and trace it with a pencil.

If the template is not included in the set, to mark a hole is a little more difficult. First outline the edges of the sink, positioning the sink so that its bowl looks down. Then turn the sink over and place it on the countertop the way it will be installed in the ready-made form. Secure it with masking tape. Align and trace the contour. On how exactly made markings, depends on the correct installation of the product and ease of use. Inside the contour a fishing line is marked for the trimmer of the cut.

Cut the hole

Before you cut the hole for the sink in the countertop, take an electric drill and make 2-3 holes one after another on the cut line, so that you get a single slit. Its length should be such that the electric jigsaw can easily pass inside. Use it slowly and very carefully to cut a hole.

If the jigsaw deviates slightly from the marking line, that’s okay. A deviation of 2-3 mm is allowed. Clean the cut line from dust and “try on” the product. It should fit freely into the hole, but at the same time should not cling and not “stray”. If the shell does not fit completely into the hole, it is slightly enlarged with a jigsaw.

Do not turn the countertop upside down while cutting, otherwise chipping may occur Source

Treating the cuts

If the material used for table tops absorbs moisture, such as wood or chipboard, then the cut line should be covered with an antifungal agent and reinforced with a special sealant that comes with the product. This protects the joint between the sink and the countertop from getting wet and prevents the process of rotting.

Roughen the surface before pretreating it with fine sandpaper. Cover the minor chips with silicone sealant. When this work is done, use a sealer. With the same help we glue the edge of the sink along the edge.

Fix the sink to the countertop

Fix the clips along the inner side of the bowl rim. The sink is placed on a permanent place, carefully press and hold for about 15 seconds. Then with the help of a level, check how evenly the product is installed. If there are no complaints, the excess sealant is wiped off, the sink is fixed in the groove until the sealant finally cures.

Many craftsmen recommend installing clips after the sealant has dried, so that the sink will not slip and will be fixed evenly Source

How to make a hole for the faucet

If you observe caution and accuracy, it is not so difficult to drill a ceramic sink. It is done in the following way:

  • On the place where the faucet will be located, a mark is drawn. That is what you need to drill. Making a hole is a task that, at first glance, is very simple, but it raises a lot of questions, especially for those who are new to it. In no case should you use a drill bit with a tip of pobedite. It doesn’t drill, it just chips the material, peels it. It is better to use a metal drill with a low speed, or maybe even a manual drill.
  • Next, holes are made in the partitions. The impact of the drill bit causes a lot of heating of the ceramic, this heating must be strictly controlled. Use a thin drill bit to work all around the perimeter of the future cavity.
  • Use a soldering iron to make notches, after which you can knock out the plug by hitting it with a hammer.
  • On the edges of the chip it is necessary to pass a jigsaw with a diamond saw in order to even out the hole.
  • The edges of the hole must be trimmed with an abrasive nozzle. In case you do not have one at home, you can also use a round file.

On some models of ceramic sinks the manufacturers specially make special marks. If you hit them accurately with a hammer, they can easily be knocked out. That way you get a ready-made hole for the faucet. The main thing is to strike carefully.

How to avoid mistakes

In contrast to specialists, who often drill the sink from the outside after installing it into the countertop, it is better to make a hole from the back side when working with your own hands. You should do this for a number of good reasons, which include the possibility of the edge of the product chipping, especially if it has too narrow a frame, scratches on its surface, and a host of other negative consequences.

The only significant advantage of drilling from the outside of the sink is the possibility to make a hole for the faucet with the most straight edges. Yes, if the hole is made from the back, its appearance can be visually less attractive, but the sink will remain intact and unscathed, and after installing the faucet, this defect will also not be noticeable.

Two kinds of sinks

The two types of kitchen sinks are the most popular right now:

And with stainless steel, and with porcelain stoneware manufacturers do not rush with drilling holes, leaving these little things to sellers.

For your information! You can arrange to have the holes drilled in the sink sales stores. Price manipulation liftable, you specify the diameter and location, pay and get a finished product with places for mounting faucets.

The problem is solved, it is possible to close the topic under consideration, but there are situations that fundamentally change the original plans. All the more, the desire to do everything with your own hands, and the pleasure that you get from a job well done is incomparable.

Doing it yourself

Simple things can turn the world upside down. Your initial desire to install the faucet on the right side in the corner will be negated if your spouse is left-handed.

hole, ceramic, sink

Apropos of note! In the kitchen, as nowhere else, great importance is given to beauty, functionality, also ergonomics. It is very uncomfortable for left-handed people to open the faucet, which is located on the right, with their left hand. Water gets on the hand.

  • All work with the product perform before installing it on a stationary place, by these simple actions you will prevent deformation of the object and premature deterioration;
  • Put the sink horizontally on a wooden base. Drill a small hole enough 5-6 mm with a metal drill bit to determine with the center of the circle;

Tip! If you use punches and a hammer, the above manipulation is unnecessary.

  • And then there are three ways to choose from:
  • Hammer and punch. Here, everything is simple, you punch with special nozzles manually, the nozzle is initially selected under the diameter of the hole in the sink for a mixer tap or faucet;
  • Specially designed punch. This is a mechanical toy that uses the extrusion method. This punch consists of a threaded pin and two nozzles, a tap and a pressing washer with a wrench head. You put a pin in the hole from the outer side, screw a washer with a head and use a wrench for tightening-pressing. The result of this manipulation is a hole in the stainless steel sink for the faucet;
  • The third way is a special drill called a carrot. The name has so caught on that even on the factory packaging of the product it is not called anything else than a drill bit. a carrot. Drill bit is represented by a cone, with a cutting edge diameter from 6 to 32 and even 38 mm. We will not describe the principle of using the drill, everything is clear.

In a piggy bank! Sometimes the consumer’s choice stops at faucets with large-diameter taps. Sink waste and trap with a big hole requires a big insertion socket. Then there are several ways out: the first is to order a hole in the store, the second is to drill a few holes of smaller diameter around the circumference. Then simply connect them to each other, removing the inner circle with a chisel. True, you will need accuracy and precision of movement.

With what to drill a hole in the stainless steel sink. we’ve disassembled, let’s move on to the stones.

Stone and under a stone

Much more interesting is the topic of drilling the seating holes in stone sinks.

Note! A simple manipulation. work with a drill bit. in practice is not very simple. A drill bit with a pobedite insert is contraindicated for this job, it does not drill as much as it cleaves, shears the material. Not bad showed itself drill for metal, but you need a low speed drill itself (ideally, it is better to use a hand drill). A high rpm will melt the edges.

  • While drilling, the material can heat up quickly, but this is difficult to control. Drilling a hole in an artificial stone sink is best done with a thin drill bit. We work along the perimeter of the entire future nest;
  • The partitions between the holes are recommended to “pass” in two ways:
  • Notch the strokes with an electric soldering iron, followed by knocking out the cork with a hammer;
  • The jigsaw is good for sawing the material. Although this process is longer, but the edge is the most even;
  • Grinding the circumference of the hole is done with a round abrasive nozzle for the entire circumference. If one is not available in the household, use a regular round file.

To the copybook! To drill the hole in the sink made of artificial stone you can also use a diamond drill bit if you have one.

Inform! Some bowls have special marks. These are places where by hitting with a targeted hammer, it is possible to punch a hole. This should be done with caution, the labels themselves are marked with paper stickers, which can slip during transport. Hitting the other point can only lead to the destruction of the material.

Where to cut the hole?

Another important issue that will arise no matter what materials were purchased sink. cut a hole in it from the front side after the installation has occurred? Or you can do it before installation and from the back side?

Each method has a number of advantages and disadvantages.

In the first option, the edges on the front side will be much flatter, but there is a possibility of screwing up the front side of the sink with the drill, and if it has a not wide edge, then split the edge.

In the other option, the risk of ruining the bowl is much less, but there is a possibility of getting a sloppy edge of the hole on the front side. In many cases this is not a problem, since the edges of the hole are covered by a crane. When turning it over, there is a possibility of unintentionally making a hole on the wrong side, thanks to this it is best to highlight the side on which you wish to install the water faucet.

In either method, it is best to put the hole further from the edge of the product, but without hitting the bowl. To do this, at the beginning of the work, you need to put the bottom nut of the water faucet to the sink and highlight its center.

The differences of sinks made of stone agglomerate

If, for example, you bought a sink made of stone agglomerate, it will be a little easier to work with.

Artificial stone sink from agglomerateThe well-known manufacturers in most cases enclose a cutter or core, with which a piece of stone, already drilled, is knocked out, but not to the end. If they are not present, it is an excellent option to use a diamond cutter or drill bit and proceed as when working with porcelain granite.

The forstner cutter can also handle the hole in the stone agglomerate product. But be prepared for the fact that afterwards it will need to sharpen, or even completely discard.

Be sure to read the instructions and operating rules before taking any action, so as not to inadvertently lose the warranty on the product.

Artificial stone

If the sink is implemented as a single unit with a countertop and the same color with it, it is an acrylic decorative stone. Of the materials listed above, this has the lowest density, so it is easiest to work with him. If the acquired sink is made of artificial stone, then the answer to the question what to drill a sink out of acrylic stone is very simple. with traditional drills for metal or wood.

The hole for a typical water tap, in many cases, has a diameter of 35 mm. In a piece of artificial stone it is easy to drill with a feather drill bit for woodwork or a forstner cutter of similar diameter. Work at a low or average speed. When there is a drilling of this material will appear the vast majority of chips, and which is part of an artificial stone plastic emits a bad smell, something like epoxy-based glue.

Sink from acrylic stoneAcrylic stone is the softest of all acrylic stone variants, thanks to that a significant portion of countertops are made of it proper. If there is a need to make a hole in it for a sink or cooktop, it is better to practice in advance on the middle of the cut out part, so as not to damage the entire countertop. Notwithstanding the fact that the artificial stone is easily sawed with a jigsaw, it is undesirable to make a cut with it. During the work with the jigsaw there are often, otherwise speaking, stress concentrators (sharp transitions, sharp angles, small cracks), which affect the life of the product.

If you are considering over what to drill out an acrylic stone countertop, then a great option would be. a router, but it is not always available.

In this variant it is allowed to cut the hole with the jigsaw less than necessary by 5 mm. Once the jigsaw work is complete, bring it to a clean size with a milling machine. On the edges it is necessary to be sure to chamfer R3, it will also reduce stresses, and make a longer life of the countertop.

How not to make mistakes

Suppose you decide to make a hole with a drill and cutter.

Often professionals make a hole when the sink is already installed in the countertop. This solution has only one advantage. the edge on the front side will be straight. And it has many more disadvantages: you can scratch the stone, damage the sink, chipping off the edge and so on.

Therefore, it is better to drill a hole on the back side. But there is a chance that the hole from the outside will have an uneven appearance. However, in this place there will be a faucet, which will cover the irregularities of the edge. There’s no risk of damaging the face of the sink.

There are two fundamentally different methods of work. The first involves working with a drill, and the second involves knocking out the loose casting plugs provided by the design. Consider each of them in order.

Making a hole in an artificial stone sink using a drill, step by step:

On some artificial stone sinks there are cast-in-place plugs that are knocked out during installation. Usually they are marked with a color on the front side. The first thing to do is to install the sink in place in the countertop, but do not fix it.

Then you need to find the right tool and beat the plugs with a hammer. A puncher with a diameter of 8 mm is suitable for this role, but not a screwdriver. The cork must be knocked out from above only: that is, from the front side. A rasp is used to smooth out uneven hole edges.

This way you can make a hole for a faucet.

  • The center is marked and the circle is drawn.
  • Using a drill along the length of the circumference is drilled holes, the distance between which is 4 mm.
  • To prevent cracking during beating out, firmly fix the sink.

If you want to increase the radius of the hole, you must draw another circle of the desired size. From the same face side along the circumference make cuts at a distance of 4 mm. Remove unnecessary parts with a punch or chisel.

Currently, quite often there is a question of how to drill a hole in the granite sink. Such circumstance is connected with the fact that in most cases you buy this sanitary ware, it lacks mounting holes needed to install a mixer or flush actuator switch.

Undoubtedly the easiest option will be the help of specialists, although following the basic recommendations you can perform the described procedure by yourself.
