What is the maximum height from finished floor to rim for a handicapped accessible lavatory?

The maximum height from the finished floor to the rim of a handicapped accessible lavatory is determined by accessibility standards, specifically those outlined in the Americans with Disabilities Act (ADA). The correct specification allows for a maximum rim height of 34 inches. This measurement is important because it ensures that individuals who use wheelchairs or have other mobility impairments can access the lavatory comfortably and safely. Setting the rim height at 34 inches helps to provide an inclusive environment that accommodates a diverse range of users.

In contrast, the other options suggest heights that exceed the recommended maximum. A height of 31 inches might be too low for some users, while 36 inches and 40 inches are both above the maximum standard, which could limit accessibility. This height regulation is part of broader ADA guidelines aiming to enhance accessibility for individuals with disabilities in public restrooms.
