How to Install a Bathroom Vanity

Joseph Pearce -

The bathroom is a room in the home that provides one of the best returns for each dollar invested in renovation. And you can have an updated bathroom without having to spend a lot of money. A new bath vanity will bring style to your bathroom décor, and may provide extra storage and countertop space.

This guide outlines the steps when installation a new bathroom vanity. All you need are basic carpentry and plumbing skills. And if you paint the walls at the same time, you can achieve a stunning transformation.

1. Position the Vanity and Mark Studs

  • Place the vanity flush to the bathroom wall
  • Make light pencil marks around the cabinet (top, side, and corners)
  • Use a stud finder and mark the location of the studs with a pencil (mark lightly right above the cabinet)
  • Level vanity. If necessary, install shims under the base of the cabinet to make sure it is level.
  • Measure, mark and drill holes for faucet pipes.

2. Attach the Vanity to the Wall

Using 2-inch dry wall screws, secure the vanity to the wall studs.

3. Install Faucet

  • Install and secure the faucet to the sink.
  • Place a bead of plumber's putty around sink drain, then set the drain in the sink hole and tighten the nut from below. Remove any excess putty.

4. Secure Vanity Top

  • Dry-fit the vanity top over the vanity.
  • Make certain the wall is right and there aren't any gaps between your vanity and wall.
  • Apply a continuous bead of silicone adhesive around the top edge of vanity, then set the vanity top into place.
  • Check to be sure the vanity top is flat and flush to the wall.

5. Reconnect Water Supply

  • Reconnect the faucet supply lines to the water supply and reconnect the trap. Use Teflon tape for tight and secure connections.
  • Turn on the water supply and test for leaks.
  • Install the pop-up drain.

6. Apply a Bead of Caulking around the Countertop

  • Apply a thin bead of caulk around the countertop edges. Use your fingertip or a damp rag to remove excess caulk.
