Learn how to install a bathroom vanity yourself for a simple bathroom upgrade
A new bath vanity can add style to your bath décor, and may also provide more storage and counter space. This project guide outlines the steps you can follow when replacing a bathroom vanity or installing small bathroom vanities.
Tip: Remember to allow for more bathroom space when installing bathroom vanities with tops or a double sink vanity.
What You Need
• Put the vanity in place and trace the outline on the wall.
• Use a stud finder to locate the studs and mark.
Tip: Double vanities require more space and plumbing considerations when installing. Consult manufacturer's instructions for details. If you're installing a bath vanity with top, include the countertop in your measurements.
• Position the vanity into place.
• Level vanity and shim at the floor if necessary. Hold level against the edge until it’s plumb.
• Measure, mark and drill holes for drain and supply pipes.
Tip: If you're installing a vanity without a top, you must also measure for the bathroom countertop you’ll be installing later. Measure the cabinet’s depth and width, adding one inch to each measurement for the top.
• Attach the vanity to the wall using 3-inch drywall screws.
• Check for level again before trimming the shims with a utility knife.
• If there are large gaps at the wall or floor, attach quarter-round moulding along the wall or floor edge with finishing nails.
Follow manufacturer’s instructions and install and secure the bath faucet to the vanity top.
• Dry-fit the vanity top over the vanity.
• Make sure the wall is straight and there are no gaps between the wall and vanity.
• Follow the manufacturer’s instructions to secure vanity top to vanity.
• Apply silicone caulk to the top of the cabinet before vanity top is set into position and firmly press down.
• Check to make sure vanity top is level and flush to the wall.
• Add backsplash and sides splash if necessary.
• Reconnect the faucet supply lines to the water supply and reconnect the trap.
• Turn on the water supply and test for leaks.
• Install the pop-up drain.
