How far should the flooring under water closets or urinals extend from the fixture base for public use?

9 inches
15 inches
18 inches
24 inches

The correct answer is: 18 inches

For public use, the flooring under water closets or urinals should extend at least 18 inches from the fixture base. This requirement is in place to ensure proper support and stability for the fixture while also allowing for sufficient space for maintenance and cleaning purposes. This dimension helps protect the surrounding area from potential water damage and ensures a safe and sanitary environment for users. It is essential to follow these guidelines to maintain compliance with plumbing codes and standards. Option A (9 inches) does not provide adequate support and space for maintenance, while Option B (15 inches) falls slightly short of the recommended minimum distance. Option D (24 inches) exceeds the necessary extension distance, which though may offer some extra space, it is not required for compliance with plumbing regulations.
