Which item is not permitted in a public restroom?

The correct item that is not permitted in a public restroom is a round bowl water closet. In many plumbing codes and standards, public restrooms are often required to have specific types of toilets that accommodate a wide range of users and ensure accessibility, particularly for individuals with disabilities.

Round bowl water closets are typically viewed as less accessible compared to elongated bowl designs, which provide more comfort and ease of use. Elongated bowls are generally required in public facilities to meet universal design standards, as they offer a larger seating area which can be particularly beneficial in accommodating all users, including those with mobility challenges.

In contrast, standard toilets, bar soap dispensers, and hand sanitizer holders are all considered standard fixtures in public restrooms. They are designed to promote hygiene and facilitate cleanliness, making them essential components in preventing the spread of germs and maintaining the health of users in public facilities.
