Remodelling a bathroom is one of the most popular do-it-yourself projects, and one that can quickly add to the value of your home. If you're installing a new vanity and sink in your bathroom, you may be confused when it comes time to hook up the plumbing to the sink. Connecting water lines to a bathroom sink is a standard process that any homeowner can master in less than an hour.

Search for the hot and cold water faucet connections that come out of the faucet; they will be high inside the vanity at the back of the sink.
Screw one water line to the hot-water connection and the other water line to the cold-water connection, using your hand to screw the connection on and then tightening the nut with a pair of pliers until it is snug.
Attach the other ends of the water lines to the water supplies at the bottom of the vanity in the same manner, taking care to connect the hot-water line to the hot-water supply pipe directly below it and doing the same for the cold. Tighten with pliers as before.
Turn on the hot-water shutoff valve directly below the new water connection; check the new hot water line for leaks at both the top and bottom connections. Tighten any leaking connection with pliers until the leak stops.
Repeat the previous step with the cold-water shutoff valve, again taking care to check for leaks at each connection.
Tips and warnings
- If your water supply lines are metal, wrap the threads with a 2-inch piece of Teflon tape before connecting the water line.
