How to Change Bathroom Sink Faucet: A Comprehensive Guide

Replacing a bathroom sink faucet is a relatively simple plumbing task that can be completed in an hour or two with the right tools and materials. Here's a step-by-step guide to help you through the process:

Materials you'll need:

New bathroom sink faucet
Basin wrench
Adjustable wrench
Plumber's putty
Teflon tape
Flashlight (optional)

Step 1: Turn off the water supply

Locate the water supply valves beneath the sink or behind the access panel. Turn the valves clockwise to stop the flow of water to the faucet.

Step 2: Remove the old faucet

Use a basin wrench to loosen the nuts that hold the faucet in place. If the nuts are too tight, use an adjustable wrench to provide additional leverage. Once the nuts are loose, carefully remove the old faucet from the sink.

Step 3: Clean the sink and faucet mounting surface

Use a damp cloth to clean the sink and the area where the new faucet will be mounted. Remove any old plumber's putty or debris.

Step 4: Install the new faucet

Apply a bead of plumber's putty around the base of the new faucet. Place the faucet over the mounting holes and tighten the nuts finger-tight. Use a basin wrench to further tighten the nuts, but do not overtighten.

Step 5: Connect the water supply lines

Apply Teflon tape to the threads of the water supply lines. Connect the hot water line to the hot water valve and the cold water line to the cold water valve. Hand-tighten the nuts, then use an adjustable wrench to further tighten them by about a quarter turn.

Step 6: Install the handles

Insert the handles onto the stems and tighten the set screws with an adjustable wrench. Do not overtighten.

Step 7: Turn on the water supply

Slowly turn on the water supply valves and check for leaks. If you find any leaks, tighten the nuts or connections as necessary.

Step 8: Test the faucet

Turn on the faucet and check that the water flows smoothly and that the temperature is correct. Adjust the handles as necessary.

Tips:

If you're not comfortable working with plumbing, consider hiring a licensed plumber.
Use a flashlight to inspect the underside of the sink and behind the faucet for any obstructions or leaks.
If the faucet leaks at the base after installation, tighten the nuts around the mounting holes further.
If the faucet leaks at the connections to the water supply lines, tighten the nuts on the lines.

By following these steps, you can successfully replace your bathroom sink faucet and enjoy a fresh, functional update to your bathroom.
