The toilet flange, also called a closet flange, is out of sight, so many homeowners aren’t familiar with it. The flange is a round coupling typically made of cast iron or of ABS plastic that might also have a metal collar on it.
The flange bolts to the floor – either concrete or subflooring such as plywood or O.S.B. The closet flange is the connector between the toilet and the sewer inlet and holds the toilet securely to the floor. When the flange fails, leaking might occur or the toilet might rock slightly from side to side or back to front. If your toilet leaks or wobbles, it’s important to check the wax ring and flange immediately.
A leaking toilet will cause a host of problems you don’t want to deal with including rotting floor boards, mold and the potential spread of dangerous bacteria and odor.

Toilet flanges and wax rings are relatively inexpensive. Most of the cost of replacing a toilet flange is in the labor.
DIY Toilet Flange Replacement Cost: A flange costs $10 to $35 depending on the quality of the material used, with the average being about $24. A wax ring can be had for $4 to $10. Look for one with a gasket attached, and be willing to pay a bit more for it because the gasket will help prevent leaks. An adjustable wrench will cost $10 to $30 depending on its quality.
Hiring a Plumber for Toilet Flange Replacement: Most plumbers have a minimum service call price, and it is usually $100 to $175. The cost of replacing a toilet flange should fall in that range, though the materials might be extra. If the house is older and/or there are problems with the subfloor, the job might be much more difficult and costly.
