What is required to be installed in a bathroom according to Article 100?

In a bathroom, the requirement to install a basin aligns with the definitions and scope outlined in Article 100 of the National Electrical Code (NEC). A basin, commonly referred to as a sink, is essential for personal hygiene and is often considered a necessary fixture in bathrooms.

The inclusion of a basin is vital not just for function but also for ensuring compliance with residential plumbing requirements, contributing to the overall sanitation and utility of the space. It must be installed correctly to allow for safe drainage and prevent potential hazards related to water and electrical systems.

While other fixtures like a shower or toilet are also common in bathrooms, Article 100 specifically emphasizes the importance of a basin as a critical component in this space, which is why this answer is the most suitable choice. This highlights the necessity of including essential fixtures that are recognized as part of standard bathroom installations.
