What is the minimum width of a stall of a non-handicapped water closet?

The minimum width for a stall of a non-handicapped water closet is correctly identified as 30 inches. This measurement is established in plumbing codes to ensure a sufficient space for users to access the toilet comfortably while maintaining necessary privacy. Such a dimension allows for effective use of the stall without being too cramped, facilitating an adequate turning radius and consideration for user movement.

When designing commercial or public restrooms, adhering to these minimum width requirements not only helps meet sanitary standards but also aligns with regulations that promote accessibility for all users, including those who may not have disabilities yet still may appreciate a more spacious design. The established standards take into account safety, usability, and convenience, ensuring that facilities function efficiently for the intended public use.
