For a family or assisted-use toilet room, what is the standard number of water closets required?

For a family or assisted-use toilet room, the standard requirement is typically one water closet. This is sufficient to meet the needs of a single-user facility, providing adequate privacy and accessibility for individuals who may require assistance, such as parents with children or individuals with disabilities. The configuration allows for a more inclusive design, ensuring accessibility while also making effective use of space.

Having a single water closet in such scenarios aligns with the goal of accommodating a range of users while maintaining functionality. In contrast, increasing the number of water closets beyond one is generally reserved for larger public facilities where higher occupancy demands may necessitate additional fixtures. Thus, for family or assisted-use scenarios, one water closet is the recognized standard.
