What is the minimum depth required for a lavatory intended for PWD use?

The minimum depth required for a lavatory intended for Persons with Disabilities (PWD) use is established to ensure accessibility and usability for individuals with varying physical abilities. The correct answer of 500 mm is based on guidelines aimed at accommodating wheelchairs and ensuring that users can comfortably approach and use the lavatory without obstruction.

This depth allows adequate space for a wheelchair to maneuver and aligns with existing accessibility standards, which prioritize user comfort and practicality. It helps ensure that the lavatory is not only compliant with building codes but also functional for those who need it most.

Other options may not provide sufficient space for maneuvering a wheelchair or could hinder the accessibility requirements laid out in regulations, making them less suitable for the intended purpose. Thus, the 500 mm depth is crucial in promoting an inclusive environment.
