Removing a Vanity with Plumbing in the Floor

Turn off the water supply to the vanity’s faucet by either closing the main water valve or by turning the handles under the sink clockwise. Turn on both the hot and cold water faucets to expel any water left in the pipes.

Place a bucket under the sink’s drainpipes to catch any leftover water in the pipes. Clamp a pipe wrench to the different slip nuts on the sink’s drainpipes, then turn the slip nuts counterclockwise to break the connections.

Move the bucket under the water supply lines under the sink. Clamp an adjustable wrench on the connections between the water supply lines and the water valves under the sink.

Clamp a basin wrench on the water line connections to the underside of the sink’s faucet. Turn the water lines’ connections counterclockwise to remove the water supply lines from the faucet.

Cut through the caulk between the back of the vanity top and the wall with a utility knife. Lift up on the vanity top to remove it from the cabinet. Back out the screws anchoring the cabinet to the wall. Pick up the cabinet and move it out of the bathroom.
