How to Install a Bathroom Faucet

Installing a new faucet is not as difficult as you might think. All you need are some basic tools. Learn how to install a bathroom faucet in this Lowe’s video:

Your sink will have one, two or three holes that will be either centerset or widespread. Make sure you buy the right size and type of faucet for your sink.

For this DIY installation project, you will need a basin wrench, adjustable wrenches, bucket, putty knife, silicone caulk and rags. Follow the manufacturer’s instructions for installation.

Remove the Old Faucet:

1. Turn off the water supply, either at the valves under the sink or at the main valve. Open the faucet to drain any water left in the pipes.

2. Disconnect the supply lines from the old faucet.

3. Disconnect the lift rod, then remove the nuts from underneath, and take out the faucet.

4. Since most new faucets come with a matching drain plug, you will want to remove the old one. Put a bucket underneath to catch any water. Remove the P-trap. Disconnect the drain from the sink. Clean around the old drain and faucet holes if you’re keeping your old sink.

Install the New Faucet:

1. Put the gasket on first, then insert the faucet through the mounting holes and tighten the nuts.

2. Follow the manufacturer’s directions for installing the handles.

3. Take the drain body, screw the nut all the way down on the drain body and position the gasket over it. Apply a small amount of silicone under the flange. Pull the drain body in place with the pivot facing the back and screw the flange on. Tighten the nut and gasket. Use mineral spirits on the top to remove any excess silicone.

4. Install the drain rod by unscrewing the pivot nut on the drain body, inserting the horizontal rod through the hole in the stopper and tighten the nut. Slide on the strap and clip. Insert the lift rod through the faucet into the strap. Push the horizontal rod down and secure the lift rod to the strap with the screw.

5. Reconnect the supply lines to the faucet.

6. Flush debris from the faucet and test for leaks. Remove the aerator. Turn on the hot and old water for about a minute. Check all connections and re-tighten if necessary. Screw the aerator back on, and you’re done.
