What type of water closet bowls are required for public or employee toilet facilities?

Public or employee toilet facilities are required to have elongated type water closet bowls primarily because they provide greater comfort and hygienic benefits compared to other styles. Elongated bowls are generally recommended in commercial settings as they allow for better ergonomics and are more accommodating for all users.

Moreover, the design of elongated bowls helps in reducing splashing, which can help maintain cleanliness in public restrooms. The International Plumbing Code acknowledges these factors, making it a standard requirement for public facilities to ensure a universally accessible and pleasant experience for users.

Other types of bowls, such as round or compact types, may not offer the same level of accessibility or comfort, making them less suitable for high-traffic public or employee areas. The elongated type stands out as the most appropriate option in aligning with the principles of accessibility and user comfort established in plumbing code guidelines.
