What is the minimum floor space (in inches) required beyond the door swing for a family or assisted use toilet or bathing room?

The minimum floor space required beyond the door swing for a family or assisted use toilet or bathing room is essential to ensure accessibility and functionality.

In this context, the correct choice indicates that the required minimum space is 30 inches wide and 48 inches deep. These dimensions are established to provide sufficient room for maneuvering, especially for individuals who may be using mobility aids such as wheelchairs. The 30-inch width allows for adequate clearance alongside the door, ensuring that it can swing freely without obstruction. Meanwhile, the 48-inch depth provides enough space in front of the fixtures and within the room for comfortable movement and usability.

This standard reflects guidelines intended to promote safety and accessibility in bathroom designs, ensuring that all users can navigate the space without difficulty. Proper space allocation is critical in both residential and commercial buildings, particularly in areas designed for family or assisted use where diverse accessibility needs must be addressed.
