The planning of bathrooms and kitchens is 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 separated by 150-200 mm from each other and mounted 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.
Even kitchens have 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.
However, since all connection work and changes to the drinking water installation can only be carried out by specialized 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.
For new buildings: the meter crack decides
For all trades - and also for the installation companies - the meter rip is the decisive measure of all things in the new building. 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 foundations 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
- Art of the building
- Number of persons
At the same time, there are also specifications in this standard for certain distance areas to be complied with. 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 standard-compliant planning can be found in DIN EN 12056 and in DIN 1988.
