Did you know the pedestal isn't what supports the sink? See how with the help of our expert tips.

A pedestal sink saves space in a bathroom but may require adding extra wall framing for support. The project will probably require several days: On the first day, install the framing and patch the wall. On the second day, finish the patching and paint the wall. Install the sink on the third day. (If you have a tiled wall, consider cutting into the wall in the room behind the sink to install the framing.)

A pedestal sink that actually sits on the pedestal makes the plumbing installation difficult and repairs nearly impossible. Buy a sink that mounts on a wall bracket and has a pedestal for looks only. Supply lines that are close together can be hidden behind the pedestal. Otherwise, let the plumbing show.

Pedestal Sink

A typical pedestal sink is essentially a wall-hung sink with a decorative pedestal underneath. The bracket must attach to solid framing, usually a horizontal piece of 2x6 or 2x8 lumber. If the bracket happens to be over a stud, notch-cut one stud in order to install the brace.

Step 1: Install Brace

Measure and mark the bracket height. To support the bracket, cut a hole in the wall that spans two studs. Cut a piece of 2x6 or 2x8 to fit between the studs and attach it with screws. Drive the screws at an angle through the brace and into the studs.

Step 2: Patch Wall

Cut a piece of drywall to fit the hole and attach it to the brace with screws. Smooth pieces of drywall tape around the edges. Use a taping blade to cover the tape with joint compound. Allow the compound to dry, then sand until the patch is smooth. Paint the patch.

Step 3: Install Bracket

Set the sink on top of the pedestal and against the wall. Hold the bracket in place and mark the position of the bracket. Install the bracket by driving screws through the wall into the 2x brace.

Step 4: Install Sink

Install the faucet and the drain body on the sink. Lower the sink onto the bracket. Slide the pedestal in place to make sure the bracket is at the correct height, and adjust it if necessary. Hook the supply tubes to the stop valves and attach the drain.

Step 5: Adjust Pedestal

Slide the pedestal under the sink. Stand back to determine if the pedestal looks level and sits squarely on the floor. Adjust it as needed. You may caulk the bottom of the pedestal or leave it uncaulked so it can be removed for cleaning.

Step 1: Prep Countertop

Drill two holes in the countertop, one for the drain and one for the faucet. There is no overflow, so use an umbrella drain (shown) that covers the drain but does not close it. Apply silicone sealant and anchor by tightening the nut from below.

Step 2: Install Faucet Unit

The faucet unit comes with flexible supply tubes already attached. Apply silicone sealant to the bottom of the faucet and drop the lines through the hole in the countertop. Anchor the faucet from below by tightening the nut and leveling screws.

Step 3: Supply Tubes and Finish

Wrap the threads of the stop valves with pipe-thread tape and attach the supply tubes. Make a tailpiece from a section of trap and attach it with a rubber washer and trap nut.
