How to Repair a Pedestal Sink


Replacing your old vanity cabinet with a pedestal sink is one of the quickest and easiest ways to remodel a bathroom . But we should warn you—pedestal sinks can be tricky to put in, even for pros. Often the pipes aren’t in the right spot, making it difficult to fit the pedestal in place and connect the pipes so they look nice. You may discover that there is no floor tile underneath the vanity cabinet, so you will have to patch or replace the floor. And you may also have to patch missing baseboard.

In the following article, we will show you how to handle the most common problems, including how to relocate your drain and water pipes for a neater installation.

You will be able to install a new pedestal sink and faucet in a day even with no previous experience. If you must relocate the pipes, plan to spend a few more days to move the pipes and patch and paint the wall. For this you will need basic plumbing skills like soldering copper and cutting and gluing plastic pipe.

For a complete listing of the tools and materials you will need, see “Tools and Supplies” below. And be sure to contact your building inspections department to see whether a permit is required for this plumbing work.
