A toilet flange, also called a closet flange, is a pipe fitting that connects a toilet to the drainage system while also securing it to the finished floor. A toilet flange securely attaches a toilet to the building's drainage system through an approved connection method. The flange is also anchored to the subfloor with a rust-proof screw keeping it stable and free from movement and then to the toilet with closet bolts.
Closet flanges are typically made of cast iron, ABS/PVC plastic, stainless steel, copper, brass and aluminum. Offset flanges include an elbow that allows the toilet to be fitted and adjusted in bathrooms where the drain pipe is close to the wall or otherwise unusually situated. Flange sizes range from 3” to 4” to 4” x 3”, 3” x 4” - these models have two different diameters. The first diameter is the one that connects to the toilet and the second size is what fits into the drain pipe.
