Chapter 6: Plumbing Elements and Facilities Bathing Rooms Fixture Clearances and Clear Floor Space Beyond Door Swing An unobstructed clear floor space 30” minimum by 48” minimum is required in this design because the door swings into fixture clearances (lavatory and bathtub). (In residential dwelling units, a lavatory adjacent to the water closet can overlap a portion of the water closet clearance if the clearance depth is increased by 10”, but keeping the space beside the water closet clear provides better access by allowing positioning for side transfers). Option: Bathtub with a Permanent Seat Bathtubs with a permanent seat require more clearance. The clearance must extend the full length of the bathtub and seat and at least 12” beyond the seat to allow proper alignment for transfer. 31
