What type of floors are required in toilet rooms other than in dwelling units?

Toilet rooms outside of dwelling units require floors that are smooth, hard, and nonabsorbent to ensure proper sanitation and ease of cleaning. These characteristics minimize the retention of moisture, which can promote the growth of mold and other harmful microorganisms. Smooth surfaces prevent dirt and grime buildup, making regular cleaning more effective. Hard surfaces resist damage from common bathroom fixtures and usage, while nonabsorbent materials prevent liquids from penetrating, thus reducing the risk of damage and unsanitary conditions.

This specification is crucial in commercial or public settings where hygiene standards must be upheld. The presence of urine or water from washing can lead to serious cleanliness issues if absorbed by flooring materials. Therefore, using flooring that meets these criteria is essential for maintaining a safe and sanitary restroom environment.
