Installing a sink, both in the kitchen and in the bathroom, is a fairly simple task. However, before starting the installation work, it is first necessary to determine the height at which we will attach the purchased ceramic. Therefore, in this article, we will explain the height at which to install, among other things, a kitchen sink, and also what to pay attention to during its installation. We will also answer the question of what size drain is optimal and how to organise the space around the sink so that it is functional and convenient.

If you want to attach your sink at the appropriate height – read this text. Our tips will help you go through the entire installation process without problems, and in addition, you will learn:
- How to choose the installation location for the sink in the kitchen and bathroom?
- How to install space-saving traps and what are their benefits?
- What is the significance of the size of the sink drain and how to avoid problems with its installation?
Sink height – what should you know?
Where exactly we place the sink has a huge impact on daily kitchen use. Of course, its location is directly related to the height of the household members. However, there is an optimal value, namely – 80-85 cm from the floor to its upper edge. This position allows for comfortable dishwashing without excessive bending. It is worth knowing that standard regulations do not unambiguously specify installation parameters, so it can be tailored to the individual needs of users.
Of course, in the case of shorter people, a better solution is to install the sink at a height of about 75 cm, while for taller people – closer to 90 cm. It's all up to you!
At what height should the sink drain be?
An important element is also the height of the sink drain. Most often, we install the drain 50-55 cm from the floor. This solution allows for the correct connection of the trap and saves space. It is worth considering the bottle model, which, thanks to its specific construction, takes up less space under the sink. Thus, you can gain free surface area in the central part of the cabinet.

Sink installation in the bathroom – at what height to install drains?
Similar to the kitchen, the height of the installation of the washbasin is of great importance for comfort of use. Typically, the optimal height is 80-85 cm from the floor, measuring from the upper edge of the washbasin. However, if you are interested in a countertop basin, you must also include the countertop in your measurements.
At what height should the washbasin drain be?
Choosing the right height also matters for attaching the drain to the washbasin. As might be expected, 55 cm also works here, i.e., it should be placed at the same height as the sink. Above this value, water drainage may be difficult, and problems with the installation of the washbasin may also occur.
What to pay attention to during the installation of a sink?
When attaching a sink, remember a few important issues, namely:
- Space functionality – both in the kitchen and bathroom, it is worth planning the installation work so that access to the sink or washbasin is convenient, and connected devices such as a dishwasher do not interfere with daily use.
- Appropriate installation height – choosing the right place largely depends on the height of the users, so it is worth adjusting it individually.
- Type of trap – modern traps are designed to better utilise space under the sink. This is especially useful in small kitchens and bathrooms.
- Plumbing installation – pay particular attention to how the sewage pipes are run and whether they allow for hassle-free installation.
Utility sink – installation height
Do you want to have a washbasin in your garage? Or maybe you need to install a utility sink in the garage? Note that in their case, there are specific requirements regarding the installation height. This type of sink must be attached approximately 85-95 cm from the floor.
In situations where this is inconvenient for us, you can refer to your own preferences. The law does not strictly regulate this, but it is recommended that the drain is located at a height of 50-60 cm, as this facilitates the easy connection of the trap.
What mistakes can occur during the installation of a sink?
Of course, various errors can occur during the installation of a sink. Therefore, it is worth getting to know them to avoid problems after installing the ceramics. The most common are primarily the incorrect height of wall mounting. A too low mounted washbasin may cause the user to bend excessively, and over time this position is particularly uncomfortable.
Washbasin height – what to be careful of?
Another problem is improperly planned water approaches, a wrong drain distance from the floor, or incorrect pipe arrangement may force relocation of the entire installation, or even additional renovation work. And undoubtedly, these are additional costs.
Lack of appropriate space for the trap is also a common installation error, especially in small kitchens or bathrooms. Installing this element can be problematic if the size of the selected model is not taken into account in the work.

Which traps are worth choosing? What can be found in the store?
Choosing the right trap is essential for the proper functioning of the sink or washbasin. Moreover, its shape also allows for effective management of space under it, or in the cabinet. Various types are available on the market, differing in functionality, size, and material of execution.
Pay attention to several popular options.
- Bottle trap – a compact installation element that takes up little space under the sink. It works perfectly in a kitchen with limited space.
- Space-saving trap – an innovative solution that allows better management of the area under the sink.
- S-trap – the traditional trap model that still enjoys greater popularity in older installations.
Remember – space-saving trap and appropriate distance from the floor!
When you want to attach a sink or washbasin, remember to correctly choose the height at which the selected ceramic will be placed. Good placement improves user comfort, and also facilitates sewage connection. So adjust the spot so that people washing their hands can do so smoothly and comfortably.
Meanwhile, a properly determined drain position and the use of modern solutions such as a space-saving trap, significantly increase the functionality of the kitchen and bathroom.
Take care of the sink drain height already in the first stage of renovation work!
As you can see, the installation of a sink or washbasin should be thought out at the design stage to avoid later problems with installation. Mainly follow the principles of ergonomics, as this way you can ensure comfortable use of bathroom and kitchen appliances like a dishwasher.
