What should be the minimum distance from a water closet to a side wall?

The minimum distance from a water closet to a side wall should be at least 15 inches. This requirement is established to ensure adequate space for the user to comfortably use the facility while also allowing for accessibility and maintenance. Spacing considerations are critical in plumbing design for both functionality and building code compliance.

Having a distance of 15 inches minimizes potential obstruction, ensuring that users can enter and exit the space without difficulty. It also accommodates the installation of grab bars if needed, and allows for proper cleaning around the fixture. Such standards aim to create a safe and user-friendly restroom environment.

A distance less than 15 inches could lead to cramped conditions, possibly making it difficult for individuals to utilize the water closet effectively, which is why it's vital to adhere to this measurement in design and planning.
