Step-by-Step: How to Replace a Bathroom Sink Faucet
Here’s a simple process to follow:
1. Turn Off the Water Supply
Locate the shut-off valves under the sink. Turn them clockwise to stop the water flow. Open the faucet to drain any remaining water.
2. Disconnect the Supply Lines
Use an adjustable wrench to unscrew the hot and cold water supply lines. Keep a bucket handy to catch drips.
3. Remove the Old Faucet
Loosen the mounting nuts under the sink using a basin wrench. Lift the old faucet out carefully.
4. Prepare the Sink Surface
Clean any old plumber’s putty or residue to ensure a smooth installation area.

5. Install the New Faucet
Place the new faucet into the sink holes. Use plumber’s putty or silicone sealant to create a watertight seal.
6. Tighten the Mounting Nuts
Secure the faucet in place from underneath using a wrench. Ensure it’s level and stable.
7. Reconnect Water Supply Lines
Attach the hot and cold water lines to the faucet. Wrap plumber’s tape around the threads for a tight seal.
8. Test the Faucet
Turn on the water supply and check for leaks. Run both hot and cold water to ensure proper flow.
