According to Article 100, a bathroom is required to have which of the following?

In residential wiring and building codes, the definition of a bathroom is key, particularly as outlined in Article 100. A bathroom is defined as a space containing a basin, which refers specifically to a wash basin or sink. This is central to the purpose of a bathroom, as it is a fixture for personal hygiene.

While a shower, toilet, or bathtub may also be present in a bathroom, the essential requirement that defines it according to Article 100 is the inclusion of a basin. Thus, recognizing the specific terminology and definitions in building codes is crucial for understanding the minimum requirements for a bathroom. The presence of a basin meets this definition and serves the functional role expected in such spaces, emphasizing hygiene and personal care.
