Urinals must have the rim at a maximum height of __________ above the finished floor.

The correct answer is that urinals must have the rim at a maximum height of 17 inches above the finished floor. This height is specified to ensure accessibility for individuals, particularly those who may require assistance or are using mobility devices. The guideline aims to provide equitable access and convenience for all users, emphasizing the importance of compliance with the Americans with Disabilities Act (ADA) requirements.

Setting the rim at 17 inches helps accommodate a wide range of users, promoting both safety and hygiene in public restrooms. Other heights may not be compliant with accessibility standards or could pose challenges for certain individuals. This specific measurement reflects best practices in plumbing design, ensuring facilities are usable for everyone.
