What defines a bathroom in terms of plumbing fixtures?

A bathroom is defined by the presence of at least one plumbing fixture, such as a tub, toilet, or shower. This definition is important for various reasons, including building code compliance and ensuring that the space meets the necessary health and safety standards. In residential and commercial settings, the requirements for the number and type of fixtures can vary, but the fundamental requirement is that a space designated as a bathroom must have at least one plumbing fixture. This underscores the purpose of the bathroom as a functional space for personal hygiene.

The other possibilities do not meet the comprehensive definition of a bathroom. For instance, a space with only a shower might not provide the variety of amenities expected from a typical bathroom. Similarly, a toilet with a bidet requirement could be too restrictive, as not all bathrooms are required to include both fixtures. The option that allows for only sinks fails to capture the essence of a bathroom as it does not encompass the variety of fixtures that could be present.
