What's Involved in the Move

Any unused sections of old pipes are carefully removed and capped off if needed. New pipes are connected to the sewer line and routed to the location. The plumber ensures that these drain lines have sufficient slope and drop for correct gravity flow. The toilet attachment, along with any additional water lines or vent pipes, is installed between floor joists.

Cost Factors

The distance from the sewer pipe to the new location varies. If the drain slope needs to be increased, there may be some rerouting needed which would add to the expense. When moving the toilet drain, the water supply line may also need to be moved. The strength of the floor should be tested to verify it can hold the weight of the toilet long term. If it needs reinforcing, the labor and materials will also add to the project cost.

Benefits of a Professional

Modifying the plumbing of a toilet can be a complex process. For most homeowners, contracting with a professional is generally the best option. In fact, local codes in many areas require a licensed plumber to be employed when working with drain pipes.
