What is a required fixture in a bathroom as defined in Article 100?

In residential wiring and electrical code, specifically as defined in Article 100, a "basin" refers to a fixture that is necessary in a bathroom setting. The term "basin" typically encompasses sinks, and in this legal context, it is a specification for plumbing and electrical installations within a bathroom.

Article 100 outlines various terms and definitions relevant to electrical installations, ensuring that all necessary fixtures, which provide functionality and comply with safety regulations, are included. The inclusion of a basin in the bathroom is essential as it directly relates to hygiene and usability. While options like a sink, bathtub, and shower are indeed common bathroom fixtures, the term "basin" is the broad definition that aligns better with the regulatory language and intent to cover the required plumbing and associated electrical work in a bathroom. Thus, understanding the definition and regulatory requirements is fundamental for compliance with electrical codes.
