Closet Flange

In Plain English

The circular fitting in the floor that the toilet bolts onto and drains through.

Definition

The fitting that connects the toilet's base to the floor and the drain pipe below, also known as a toilet flange. It provides a watertight seal via a wax ring between the toilet and drain, and anchors the toilet to the floor with closet bolts. The flange must be set at the correct height relative to the finished floor to ensure proper sealing.

Example

The tile installer raised the floor height by 3/8 inch, requiring an extension ring on the closet flange to maintain proper height.
