Show answer & explanationAnswer & explanation
Correct answer: A. 34 inches
According to ADA accessibility guidelines, the rim or counter surface of a lavatory must be mounted at a maximum height of 34 inches above the finished floor. This ensures it is accessible for individuals using wheelchairs.
Why the other options are wrong
- B. 32 inches is below the maximum allowed but not the exact specified limit.
- C. 36 inches is too high and would not meet ADA accessibility requirements for a lavatory rim.
- D. 30 inches is too low and not the specified maximum for a lavatory rim.
