How To Install a New Bathroom Faucet? Step-By-Step
Your bathroom faucet may vary depending on the number of holes in the vanity top or sink. The basic installation procedure is the same for all faucets, including single handles or center set faucets.
Here are the step-by-step instructions on how to install a new bathroom faucet:
Required Tools & Equipment
The following tools and materials you will need to complete this DIY project:
- Adjustable wrench
- Philips head screwdriver
- A new faucet
- Plumber’s Putty
Step 1: Choose A New Faucet
If your sink where you want to install a new faucet has three holes within 4 inches distance, you will need a center-set faucet. You can also pick a single-hole faucet having a deck plate to hide the vacant holes. This faucet will include a spout, handle, valves, and other important components.
For a sink with holes distant 8 inches, you will need a widespread faucet consisting of a handle and a hot and cold water valve.
Choosing a faucet labeled WaterSense is highly recommended to ensure water and energy conservation.
Step 2: Shut Off the Water Supply
- Find the main water shut-off valve and turn it off.
- Turn on your old faucet to drain excess water.
- Keep a bucket and towel beneath the drain pipe to collect water.
- Remove the P-trap from the underside of the sink connected to the drain.
- First, unscrew pipe connections, then unscrew metal nuts.
- Use a basin wrench to disconnect the water supply lines attached to the faucet valve.
Step 3: Remove the Old Faucet
- You will find plastic lock nuts under your sink.
- Turn those nuts in the counterclockwise direction by hand.
- If they are hard to unscrew, use a wrench to make them loose. Remove nuts and rubber washer.
- Remove the old faucet from the mounting holes and also detach the rubber gasket.
- If the sealant is hard to remove, use a putty knife to pry the old faucet.
Step 4: Clean The Area Before Installing New Faucet
You will see a lot of dirt and buildup under the sealant of your old faucet.
- Pour water and add soap to clean the area.
- Use a soft sponge or at least an abrasive pad to scrub the hard stains and limescale.
- If there is tough residue on the sink, scrape it off with a putty knife.
Step 5: Install New Faucet & Align It
- Install a new bathroom faucet after assembling its components by following the manufacturer’s guidelines.
- Add the plumber’s putty at the bottom of the faucet.
- Place your faucet gasket at the tailpiece by keeping it between the sink and the base of the faucet.
- Put the assembly inside mounting holes and press the faucet over the sealant for better grip.
Note: You can also use Silicone caulk to seal the edges extra waterproof.
Step 6: Thread Washer & Basin Nut
- Thread washer and basin or lock nuts on the valve tailpiece.
- Tighten the nuts using a wrench or by hand. Avoid over-tightening.
- Adjust the bathroom faucet on holes and keep it centered on top of the sink.
- Tighten all nuts with a basin wrench but be careful of over-tightening.
- Clean the extra putty from the base and add a new plumber’s tape to connect lines.
Step 7: Install New Drain Pipe
- If your new faucet has a drain pipe, install it to replace the old drain.
- Use a plumber’s putty around the drain hole and fix the new stopper.
- Beneath the sink, insert a rubber gasket and tighten the nut on the drain pipe.
- Screw the P-trap at the end of the drain pipe to complete the drain assembly.
Step 8: Restore Water Lines & Run A Test
- Reconnect the water lines and move the shut-off valve in a counterclockwise direction.
- Turn the handles on the faucet to allow water to flow through the spout.
- Keep the water running for a minute to check for leaks. If there are no leaks, the installation process is complete.
