Accessible urinals MUST have an elongated rim at a maximum height of ____" AFF.

The requirement for accessible urinals to have an elongated rim at a maximum height of 17 inches above the finished floor (AFF) aligns with the guidelines set by the Americans with Disabilities Act (ADA). This height is designed to ensure that individuals with disabilities, particularly those who may be using a wheelchair, can use the urinal comfortably and independently.

The specification of 17 inches provides an accessible solution that accommodates a wide range of users, including those with various mobility impairments. This height facilitates convenience and usability without compromising on accessibility standards mandated by federal regulations.

Other height options do not meet the ADA requirements, as they either exceed the maximum allowable height or do not accommodate a broad spectrum of users efficiently. Therefore, having the top of the urinal rim at 17 inches AFF is the correct standard to ensure compliance and proper accessibility in public restrooms.
