Which item qualifies as a fixture in plumbing?

A fixture in plumbing refers to any device that is permanently installed and connected to the plumbing system, contributing to its overall function. A fixed plumbing feature that is part of the structural design meets this definition perfectly, as it is intended to remain in place for the long term and is essential for water supply, drainage, or waste management.

This quality of being fixed and part of the structural design distinguishes it from other options, which either represent movable appliances, such as a stovetop or refrigerator meant for cooking and food storage, or decorative elements that do not serve a functional plumbing purpose. A fixture’s role in ensuring the proper functioning of the plumbing system underscores its importance in any kitchen design.
