Illinois Plumbing Code Practice

For public use, what type of water closet bowls are required, and what type of seat should be installed?

1. Round bowls and wood seat

2. Elongated bowls and anti-microbial plastic open front seat

3. Square bowls and cushioned seat

4. Oval bowls and metal seat

The correct answer is: Elongated bowls and anti-microbial plastic open front seat

The requirement for public use water closets is based on health, hygiene, and usability considerations. Elongated bowls are preferred for public restrooms because they provide greater comfort and are more accessible, particularly for a wider range of users, including individuals with mobility challenges. The choice of an anti-microbial plastic open front seat further enhances hygiene by reducing the risk of bacterial growth and facilitating easier cleaning, which is especially important in public facilities where many different users might come into contact with the seat. The open front design encourages cleanliness while minimizing contact with the seat itself, promoting better sanitary practices. Other options, such as round bowls or materials like wood and cushioned seats, do not meet the same standards for hygiene and accessibility that are essential in public restroom facilities. These alternatives may not address the varied needs of the public adequately, nor do they offer the sanitary benefits required in environments with heavy usage.
