How Many Toilet Cubicles Do You Need?

When planning a washroom refurbishment or new project, it is important to understand the regulations governing the number of toilets and facilities required for any given space. There are regulations in place to cover everything from offices and places of work to schools, educational institutions and leisure facilities. These guidelines cover the minimum number of toilet cubicles, urinals and wash basins that are required per person.

We have put together a guide to help you understand the relevant guidelines for your sector.
