Proper planning for water connections


The planning of bathrooms and kitchens is also often tricky, because the corresponding water connections must be planned in advance. What you should pay attention to, when it comes to planning the water connections, and what you should know, you can read in this post.

Minimum dimensions and specified heights

Corner valves must always be 150-200 mm apart from each other and must be installed at a specific height. Washbasins are always exactly 88 cm high, measured from their upper edge. These standard dimensions - and many more - are mandatory. This often complicates sanitary planning because you can not always do what you want.

For kitchens, too, there are certain minimum dimensions that must be adhered to. Here, however, it is easier to cope with the standard dimensions and installation depths, and there are fewer problems in planning the water connections correctly.

But since all connection work and changes to the drinking water installation can only be carried out by specialist companies - this is stipulated by law - you should always leave the planning to a specialist company. It's also about water pressure, the calculation of tapping points and other highly complex things when planning the installation in a house. As a layman you have hardly a chance to ever really look through and make mistakes.

In the new building: the meter crack decides

For all trades - and also for the installation companies - the meter rip is the decisive measure of all things in new construction. The meter is placed near the door in any room by the site supervisor or construction polisher and serves as a binding measure of further work, including for sanitary installations.

Standardized basics for planning

There is also a mandatory standard for the planning of floor plans in the sanitary and kitchen sector: DIN 18022. Among other things, it requires that planning be based on certain criteria:

  • Number of sanitary facilities
  • Type of building
  • Number of people

At the same time, there are also specifications for certain distance surfaces to be complied with in this standard. All built-in appliances such as fans and lights are also included in the planning, which must also have certain lateral clearances, as well as tapping points for drinking water and water connections.

Further regulations for standardized planning can be found in DIN EN 12056 as well as in DIN 1988.
