How Big Is A Commercial Bathroom?

For design of a brand new commercial bathroom or reconstruction of an old one consider these regulations. First of all, think about the size, plumbing standards, and general ergonomic requirements. The average size of a bathroom is 9 ft. by 11 ft.

For instance, Americans with Disabilities Act (ADA) has the larges
impact on bathroom layouts. A 5 ft. unobstructed circle is required for a wheelchair to turn around. Lavatories need least 4 ft. clearance in front. Inward swinging doors need 18" on the side and 5 ft. clear for someone in a wheelchair to open. The list goes on – check it online with the building regulations. What no one tells you is that the fire regulations will dictate the size on regular toilets as well. Likewise the building regulations will affect the size of any new build toilet facilities on a house.
