In order not to encounter an annoying situation when time and money was spent on buying plumbing, but it doesn’t fit in the intended place, it’s still necessary to determine the size of the bathroom sink before going to the store — such a technique will save money and nerves. Do you agree?

We will figure out how to cope with this task correctly by studying the issue in more detail. In the article, we identified the parameters that should be guided by, gave tips on choosing the optimal sizes of plumbing and placing a sink in the bathroom.

Significant measures of a plumbing fixture

Beautiful forms, original ideas in the catalogs of famous manufacturers - all this throws into shock when you have to choose a washbasin. Often you want to comply with the latest trends in terms of design, surprise friends and get maximum comfort during operation.

The main criteria by which to navigate, measuring the sink, there are only four. It is they who play an important role in the selection of a product - if you overlook it, then subsequently the product will clearly disappoint.

Shell measurements
An example of taking measurements from a standard sink. Explanations for the scheme: L - washing length, B - product width, H - depth

Among the important parameters there are such:

  • product depth;
  • distance to drain;
  • width;
  • length.

Depth. This is a measure from the top of the structure to the inside of the bowl. It is he who indicates the convenience of further operation - it is not worth taking less than 15 cm. Regardless of how attractive the designer's idea is.

Distance to drain. The parameter affects whether the product will fit well in its designated place, given the location of the communication taps. Measured from the top cut of the bowl to the most protruding bottom point in the bottom. The measure is removed on the outside.

Width - this is the number of centimeters from the outside of the device, to the extreme inside, which will be in contact with the wall of the room.Here it should be guided precisely by measurements taken over the product, including the sides.

Sink length
If we take the indicators of width and length along the inner walls of the bowl without taking into account the width of the bead, it is likely that the chosen option simply will not fit into the niche allocated to it in the bathroom

Length. Measure should be taken from right to left - from the right wall to the left, including the sides. Otherwise, the sink will protrude strongly beyond the allocated space.

These are all standard values ​​that the manufacturer indicates in the passport to his product. If you do not want to ask the consultant for an accompanying document, all measurements can be performed using the tape measure. They have to be compared with the parameters characteristic of your bathroom.

How to determine the correct size?

The measurements of a product ideally suited to a particular bathroom depend on the availability of free space - the more it is, the easier it is to find the right thing.

Regardless of the dimensions of the room, you should carefully approach the depth of the bowl, because too small will be extremely uncomfortable.

Distance to drain
The distance to the drain hole from the upper edge of the washbasin must be at least 15 cm. Otherwise, splashing water when washing hands is guaranteed

The market offers products with a length of 40 to 70 cm or more. The width of the sinks is 30 to 60 cm or more. As for these parameters, for comfortable use, you should choose a device that has at least 25 cm in length and width.

Here we are talking about the size of the bowl - do not confuse it with the overall dimensions of the product, helping to determine whether it will fit into the designated opening.

For a compact bath, more suitable small sink - it is convenient to use and does not take up much space. If you choose a large one that is installed on a suspended countertop, then in addition to this design, something else is unlikely to enter.

Moreover, large-size mounted solutions require the availability of free space - the more it is, the more elegant the product looks.

With close placement, the expected effect will not work - there will be a feeling as if the bathroom is cluttered and a lot of unnecessary plumbing has been installed in it.

In a spacious bathroom, it is advisable to install a massive or original sink. It can become a highlight of the interior, which will catch the admiring gaze of guests and friends who come to visit.

Unusual sinks on a pedestal
Unusual sinks on the pedestal can become the central point of the bathroom - attention, enthusiasm and respect for the owner of such a miracle are provided. No one will even think whether it is convenient to use this model.

We should also mention a parameter such as height - we are talking about the distance from the floor to the top side of the device. This feature is important if purchased. model with stand, on legs or on a pedestal. After all, you just can’t shorten all this - you can damage the product by inexperience.

Therefore, you should be guided that the optimal figure is from 80 to 96 cm. After all, over the sink you have to wash your hands, wash yourself and carry out other hygiene procedures. And this means that it should be convenient for the user with his growth to put his bent hands under a stream of warm water.

It turns out that the height is completely dependent on the growth of family members about to buy a new washbasin to equip the washbasin.

For mounted models, this option is not relevant when selected. Here, the question of height can arise only during installation work.

For mounted models, installation height is important
When mounting mounted models, you should always focus on the growth of potential users - people with a height of 155-167 cm will be extremely uncomfortable to use a refined sink suspended 95 cm from the floor

Therefore, it is important even at the stage of wall cladding to put labels at the right height so that no decorative tile elements with voluminous and protruding patterns prevent the washbasin from being installed close to the wall.

What else affects the choice of product

In addition to sizes, a lot of other factors affect the choice of the buyer. Among which are functionality, completeness, color, material, shape of the product. Some consumers want a device from a well-known company, while others value the original design. They are not interested in convenience, the main thing is that the sink should impress with its originality.

Functional holes

For a simple buyer, an important criterion is the functionality of the washbasin. The holes provided for during manufacture are responsible for this.

These include:

  • drain;
  • overflow;
  • hole for the mixer;
  • slots for fasteners.

If all sinks have an outlet for used water, then not every plumbing manufacturer provided protection against flooding of the lower neighbors.

Overflow sink
It is advisable to choose a model with overflow - this hole is located on one of the side walls. In the event of a bowl overflow, excess waste liquid will leave it, falling into the sewer rather than onto the floor

Concerning mixer selection, then you should pre-determine the model in order to have an idea of ​​the required number of slots.

For mounted models, 2 holes are made on the rear wall during production, so that it is convenient to fix the product. The same rule is observed for washbasin sinks that are to be placed on the pedestal - anyway, they are pre-fixed on the wall.

When you purchase a sink with an insufficient number of holes, you can drill the necessary ones. This will require skill - one awkward movement will ruin everything. Despite the fact that the structure can withstand up to 100 kg weight without problems, the glaze is easily scratched.

Additional accessories to the device

A caring manufacturer of sanitary fixtures tries to satisfy the needs of customers as much as possible.

Therefore, together with the prefabricated washbasin capacity, it can supply a protective mesh to the drain hole, bottom valve cork for overflow, if the model assumes its presence, siphon, dowels, bolts, nuts, gaskets made of plastic or rubber.

All these devices are designed to simplify the process as much as possible - you do not have to go around and pick up the necessary components for installation separately.

When surface models for countertops, all parts are also supplied, as well as with the construction mounted in the pedestal.

One minus - all this significantly affects the final cost of the sink. You should be prepared for such a turn, because buying cheaper fasteners can result in a sink falling with further unpleasant consequences.

Product shape and material

As for the form, here the choice is extensive. In addition to rectangular, round, oval and trapezoidal, asymmetric and corner models.

The decision to purchase this or that device completely depends on the preferences and dimensions of the bathroom - the more the latter, the more diverse the range of suitable models.

Material is also important - manufacturers offer both natural and polymer options. Moreover, plastic structures in terms of beauty and functionality are not much inferior stone products or glass models.

When considering options, it should be remembered that a sink for $ 500-2500 can also easily crack, as well as for 50.

How not to screw up during the repair?

So that after installing the necessary plumbing fixtures do not have to regret and stumble on the corners of the furniture in the bathroom, it is better to take into account a number of mistakes made by others.

The most unpleasant problem will be the size of the sink chosen for the bathroom. It can not only spoil the mood with its appearance, knocking out of the overall harmonious picture, but also bring a number of troubles.

Possible problems:

  1. Too small a product is inconvenient to use. Especially when the family is quite large men.
  2. A large washbasin can clutter a room if its area is up to 8 m2.
  3. The overall hinged product must be mounted on the wall, ready for the upcoming load - this is at least 150 kg on the front edge of the sink.
  4. Height is simply obliged to be optimal for all family members in order to ensure comfort during operation.

It is important to immediately stop the flight of your imagination if the apartment has a combined bathroom of 4-6 m2, no matter how much I would like to get a unique design device. In such a situation, it is advisable to stop on small sinks.

For greater convenience, apply various techniques and innovative solutions that make the room as functional as possible.

The option of using a sink combined with a drain tank has one significant minus - if the family consists of stunted people and the drain tank is high, then using this good of civilization will be extremely inconvenient.

When the growth of consumers is more than 160 cm, such a wash basin will be very useful. Especially if the bathroom does not differ in size.

Separately, it is worth considering the problem that concerns mounting outboard models. It is extremely important to carry out all the work after the additional strengthening of the wall.

This is especially true for bathrooms whose walls are sutured with plasterboard sheets. So that such a coating can cope with the load when using the washbasin, it will have to be strengthened by putting a few more metal profiles.

    When I did the repair, I didn’t even think about the fact that the sink might not fit, but it happened just like that. I had to go change. The seller asked what the reason for the replacement was, and when he found out, he offered a sink with a "superstructure" above the washing machine. It turned out to be really convenient - now there is much more free space in the bathroom. In the morning there is a place where you can conveniently put shaving accessories, toothpastes, etc., do not try to fit everything on a patch.

      Alexander, it's funny to buy a sink and not think about whether it will fit or not. How did you even change it ?! It's all your fault!
      We had another problem: the sink was installed about 7 years ago, everything was fine, everything was fine, but then I wanted to make it built into the “cabinet”, and this is already stealing space. Anyway, it turned out to be expensive, they decided, like you, to install a new sink above the washing machine. It seems like it has become more spacious in the bathroom, and a “new surface" for use, but for those who have the machine open upwards, this option is categorically contraindicated (or you still have to change the washing machine).
