Removing the Old Vanity

Start by removing the old vanity. Unscrew the countertop, disconnect the plumbing, and remove the cabinet. If the old vanity is secured to the wall, you may need to cut through the drywall. Be cautious not to damage the surrounding area.

Installing the Vanity Cabinet

Position the new vanity cabinet in place, ensuring it's level and centered. Mark the wall studs and the location of the plumbing connections. Drill pilot holes and secure the vanity to the wall using screws. Attach the vanity to the floor for added stability, if necessary.

Installing the Vanity Top

Measure and cut the vanity top to fit the cabinet. Apply construction adhesive to the cabinet's top surface, then position the vanity top in place. Secure it with screws from underneath. Allow the adhesive to dry according to the manufacturer's instructions.

Plumbing Connections

Install the faucet and drain assembly according to the manufacturer's instructions. Connect the supply lines and P-trap, ensuring all connections are tight and secure. Use plumber's putty to create a watertight seal around the drain.

Finishing Touches

Apply caulk around the perimeter of the vanity top, creating a watertight seal. Allow the caulk to dry completely. Finally, apply silicone sealant to the seam where the vanity top meets the wall to prevent water from seeping behind the vanity.
