You have to decide if you need to hire a professional during a kitchen remodel or bathroom remodel. Some elements of the remodel require their expertise but you can cut the costs some if you complete some of the remodel yourself.

One job you can do on your own during a bathroom remodel is to install a pedestal sink. This is an easy job for the amateur plumber and repairman. Here is how to start:

Before you start demolishing your old sink or tearing apart your bathroom, you should read the instructions on the new pedestal sink to ensure your wall can support it and that your home meets the plumbing requirements for the model you purchased. The installation becomes much more complicated if you need to reroute your plumbing.

If everything is in good shape, you can begin the installation. The first thing to do is to shut off the water valve beneath the current vanity and turn on the faucet to release residual water in the base and plumbing.

Now loosen the bolts to disconnect the drain pipes and disconnect the water lines from the vanity and valves.

Then use a razor blade to cut the sealant that is connecting the vanity to the back wall or backsplash in your bathroom. If the top of the vanity is connected to the cabinet, you will need to run the razor blade along the bottom of the vanity to remove it too. You should now be able to lift the top right off. Then unscrew the vanity cabinet from the back wall and the floor and remove it from the bathroom.

Now is a good opportunity to install new plumbing hardware and valves since it is visible and the vanity is no longer obstructing access. This should eliminate the hassle of repairing old plumbing at a future date after the pedestal sink installation.

The model of pedestal sink you bought might need an additional support bar installed in the wall behind it. To do this you need to cut out a section of the drywall near the top of the sink and saw out indents in the support beams behind in. Then slide in a new horizontal support beam for the pedestal sink. Then repair the wall surface.

You could use this opportunity to paint the bathroom wall or install a tile backsplash behind the sink since there is nothing obstructing access.

Now position the pedestal sink base 10 inches from the wall and set the sink basin on top of it. The basin should be flush against the wall. Adjust the distance of the base from the wall until the basin is flush.

Now mark the anchor holes for the pedestal sink along the back wall and the floor and install hanger bolts on the wall. Leave an inch extending from the wall.

Secure the base to the floor with a lag bolt and washer. Don’t overtighten this bolt.

Now position the sink basin over the lever hanging bolts and connect to the pedestal base. Tighten all the bolts but don’t overtighten.

You can now turn the water on in your bathroom again and run the faucet to ensure that there are no leaks from the bolts or anywhere else there shouldn’t be. If you don’t see any links, the installation is complete.

You can now continue on with your bathroom remodel.
