How to install or replace a bathroom vanity
The bathroom has changed over the years from a modest room to a multipurpose area. Installing a bathroom vanity allows more storage in a limited space.
Prepare the installation
- 1.1 - Turn off the water supply.
- 1.2 - Determine and mark the location of the cabinet, considering that the plumbing coming from the wall should be located at the centre of the cabinet.
- 1.3 - Remove the doors to allowing you more room to work.
Mark the nailing location
- 2.1 - Using a stud finder, determine the location of the studs that will be used for nailing.
Cut plumbing holes in the cabinet
- 3.1 - Measure the exact location of the pipes.
- 3.2 - Mark the size of the openings and make the cutouts with a jigsaw or a hole saw.
Place the vanity
- 4.1 - Move the cabinet in place and make sure that it's plumb and level.
- 4.2 - If it's not level, shim the cabinet along the stud marks on the wall and on the floor.
Anchor the cabinet
- 5.1 - Drill 3/8 in holes through the cabinet, the shims and into the studs near the top of the cabinet. At the top of the cabinet, one screw for each stud should be enough.
- 5.2 - Repeat this step at the bottom of the cabinet.
- 5.3 - Make sure the cabinet is level and adjust with shims if necessary.
- 5.4 - Cut away any protruding shims with a utility knife.
Attach the countertop
- 6.1 - Apply a bead of caulking around the top of the cabinet.
- 6.2 - Lay the countertop on the cabinet while sliding it against the wall and pressing firmly to solidify the joint.
- 6.3 - Let dry and reinstall the doors.
- 8.1 - Apply a bead of silicone between the countertop and the wall to seal against water.
Reconnect the pipes
- 9.1 - Reconnect the pipes and the P-trap, and connect the pipes to the valves.
- 9.2 - Tighten the nuts with a wrench.
- 9.3 - Open the water to verify the watertightness of all connections. Tighten again if necessary.
