How To Replace A Bathroom Sink Faucet And Drain

Replacing a bathroom sink faucet and drain is a relatively simple plumbing project that can be completed in a few hours. By following these step-by-step instructions, you can save money on professional installation costs and get the job done right.

Gather Your Materials

Before you start, you'll need to gather the following materials:

New faucet and drain assembly
Wrench
Pliers
Screwdriver
Putty knife
Plumber's putty
Basin wrench (optional)

Turn Off the Water Supply

Once you have your materials, turn off the water supply to the sink. There should be two shut-off valves under the sink, one for hot water and one for cold water. Turn both valves clockwise to close them completely.

Disconnect the Old Faucet

Use a wrench to disconnect the water supply lines from the old faucet. Then, use a screwdriver to remove the screws that hold the faucet in place. Once the screws are removed, you can lift the old faucet out of the sink.

Clean the Sink Basin

Use a putty knife to remove any old plumber's putty from the sink basin. Then, clean the basin thoroughly with a damp cloth.

Apply Plumber's Putty

Apply a bead of plumber's putty around the base of the new faucet. The putty will help to seal the faucet and prevent leaks.

Install the New Faucet

Place the new faucet in the sink basin and tighten the mounting screws. Make sure that the faucet is level and secure. Then, reconnect the water supply lines to the faucet.

Install the New Drain

If you are also replacing the drain, remove the old drain by unscrewing the drain stopper and then the drain body. Apply plumber's putty to the base of the new drain and insert it into the sink basin. Tighten the drain body until it is secure.

Turn On the Water Supply

Once the new faucet and drain are installed, turn on the water supply and check for leaks. If there are any leaks, tighten the connections until the leaks stop.

Finishing Touches

Once you are satisfied that there are no leaks, you can finish the job by installing the handles on the faucet. If your faucet has a separate sprayer, install the sprayer as well.

Congratulations! You have now successfully replaced your bathroom sink faucet and drain.
