What must a toilet room have if it installs two or more fixtures that receive human waste?

In a toilet room where two or more fixtures are installed that receive human waste, it's crucial to ensure proper sanitation and hygiene. One of the key requirements is the inclusion of at least one floor drain to effectively manage any spills or overflows that may occur. This helps to maintain cleanliness and provides an efficient method for drainage, especially in case of cleaning or emergencies.

The addition of an accessible hose bibb supports maintenance needs. It allows for easy access to water for cleaning purposes, ensuring that the area can be kept hygienic and properly maintained. Together, the floor drain and hose bibb fulfill critical plumbing standards to promote sanitation in a space designed for human waste.

Other options either do not address the essential requirements for managing waste or do not align with the necessary standards for a toilet room with multiple fixtures. For instance, merely having a urinal and a sink does not ensure proper waste management and does not include provisions for cleanup, while a separate ventilation system, although important for reducing odors, is not a pressing requirement compared to drainage and maintenance access in this context.
