How wide and deep must water closet compartments be for floor-mounted units?

The requirement for the width and depth of water closet compartments for floor-mounted units is specified to ensure adequate space for user comfort and accessibility. The correct dimensions are established in the International Plumbing Code to provide sufficient room for operation while maintaining privacy.

A width of 30 inches is considered the minimum needed to allow for the door to open without obstructing the space and to ensure that users can comfortably access the unit. A depth of 60 inches provides enough clearance in front of the toilet for seated use as well as maneuverability. This standard allows for the necessary space to place fixtures appropriately without overcrowding, ensuring they meet user safety and comfort requirements.

These specifications balance practicality and functionality while also addressing the need for accessibility in restroom designs, thus the answer of 30 inches by 60 inches meets the code requirements effectively.
