What is the minimum clearance required for a flushometer from the bottom of the grab bar in an ADA stall?

The minimum clearance required for a flushometer from the bottom of the grab bar in an ADA stall is 1-1/2 inches. This requirement is established to ensure that individuals using the grab bar can have unobstructed access and functionality while maintaining safety and comfort.

In ADA-compliant stalls, the placement of fixtures like flushometers must take into account the functional needs of individuals with disabilities. The 1-1/2 inch clearance allows for safe operation of the flushometer without interfering with the grab bar, which is an important support feature. Ensuring this clearance helps prevent accidents and provides ease of use for individuals who may rely on the grab bar for balance or support while accommodating their personal hygiene needs.

This thoughtful design consideration aligns with the ADA guidelines, which aim to enhance accessibility and usability in public restrooms. The other measurements do not provide the necessary space for safe interaction between the flushometer and the grab bar, thus they do not meet the standard set by plumbing codes and ADA regulations.
