What is the minimum size requirement for a resident bathroom that contains only a toilet?

The minimum size requirement for a resident bathroom that contains only a toilet is 3 feet by 6 feet. This dimension is established to accommodate the toilet comfortably while ensuring adequate space for accessibility and use. A 3-foot width provides enough room for the toilet itself and allows for a standard amount of clearance. The 6-foot length enables proper installation and gives enough space in front of the toilet, which is essential for usability and compliance with safety standards. Thus, this dimension is considered appropriate for residential facilities, ensuring that basic needs are met in a practical manner.
