Installing a Bathroom Vanity Sink


Bathroom vanity cabinets

Installing a bathroom vanity sink in a vanity is simplified by the fact that the supply lines and the drain are all hidden within a cabinet, according to the most referred Fort Worth plumbing experts.  If the cabinet has no back, simply attach it to the wall so it encloses the plumbing.  However, if the cabinet has a back, measure and cut three holes for the two supply lines and the drain.

A high-quality vanity cabinet is made of hardwood to resist water damage.  A less expensive cabinet made of laminated particleboard will quickly disintegrate if it gets wet.

A vanity top typically is a single piece comprised of a bowl, countertop, and backsplash. Acrylic or plastic vanity tops are inexpensive, but they scratch and stain more easily than other materials.

Plumbing Pro Tip of the Week

Tip #1  The stop valves and drainpipe should be in place and close enough together to be enclosed by the cabinet.  If your vanity cabinet has a back (many do not), remove the handles from the stop valves.  Ten measure and cut holes for the drain and the two supply pipes.

Tip #2  Slide the cabinet into place and check it for level in both directions.  If necessary slip shims under or behind the cabinet.  Drive screws through the cabinet framing into wall studs to secure the cabinet.

Tip #3  Set the vanity top upside down on a pair of sawhorses and install the plumbing, which will include:  a faucet, drain body, and pip-up assembly.  Check the manufacturer’s instructions for details.

Tip #4  Set the top onto the cabinet and check that it is centered.  Remove it, apply caulk or adhesive along the top edge of the vanity, and reinstall the top.

Tip #5  Connect the supply tubes to the stop valves and then connect the trap and drain assembly.

PLUMBING TRADE SECRETS:  A vanity cabinet can be installed anywhere as long as the stop valves and drain line fit inside.  A single-piece vanity top rests on top of the cabinet and is typically held in place by its own weight and a bead of caulk or adhesive applied to the top edge of the cabinet.
