2-1/2 feet x 5 feet is the standard bath tub size. 32 inches x 32 inches is the typical size of shower stalls. 2-foot depth is standard for actual space for clothes along a closet wall. 3-foot hallways are standard inside a home. 2-foot deep cabinets in the bathroom are standard. 32-inch doorways are ideal.
This means that if the door width is 32 inches, you must have a passage of 32 inches wide and 32 inches long of clear space leading into the bathroom. Once inside the bathroom, you will need a minimum of 21 inches of space in front of the toilet, sink, tub or bidet and 24 inches of clear space in front of a shower.
