The cost of replacing a toilet depends on the cost of the replacement toilet as well as the cost of a plumber to install it. Angie's List says that toilet installation rates range between $125 to $260 as of 2014. This does not include the cost of a new toilet.
Certain factors can drive the toilet replacement charge higher and include asking the plumber to dispose of the old toilet and whether other toilet components are in working condition. A replacement service typically provides a new wax ring to seal the drain as well as a new supply line and new anchors.
