What should be the minimum depth of ambulatory accessible toilet compartments?

The minimum depth for ambulatory accessible toilet compartments is established to ensure that individuals with mobility impairments can use the restroom comfortably and safely. A depth of 60 inches provides adequate space for movement within the compartment. This dimension accommodates the turning radius needed for someone using mobility aids, such as a wheelchair or walker, and allows for the installation of grab bars, which are essential for support.

Setting this requirement at 60 inches enables compliance with accessibility standards like those outlined in the Americans with Disabilities Act (ADA), emphasizing the importance of providing a safe and functional environment for all users. The other dimensions listed do not meet the standard as they are either inadequate or exceed the necessary specifications for such facilities. Hence, 60 inches is the correct and recommended dimension for ambulatory accessible toilet compartments.
