WC School toilets
School toilets must be available in sufficient numbers and be quickly and easily accessible. Clean and attractively designed toilet facilities are important for acceptance and use by the students.

Detached from design aspects, the following criteria are key when planning toilet rooms:
- How many students and teachers / staff have to be provided with toilets?
- What is the probability of using the toilets / urinals and hand basins at the same time?
- Where are barrier-free toilets needed? It must also be taken into account here whether individual areas of the school, such as B. the sports hall or the auditorium should be used separately.
- Where is or should the toilet facility be located? The following considerations can play a role here:
- Are they easily accessible from the outside area or the schoolyard?
- Are there student toilets on every floor where classrooms are located?
- Are the toilet facilities for teachers located in the vicinity of the teachers' room or the administration wing, and in the case of large school systems also in the vicinity of the lounge or meeting and preparation rooms?

In the case of boys' toilets or toilets for male employees, at least one third must be designed as a toilet and the rest as urinals.

There should be at least one disabled toilet per toilet facility. This must be kept available in accordance with the requirements for the barrier-free design of toilet rooms.
