how-to-replace-a-bathroom-faucetIt doesn’t take much to give your bathroom a brand new look and feel. In fact, one of the simplest things you can do is replace your old sink faucet with a new one, and your bathroom will automatically feel refreshed without (putting a dent in your wallet).

Materials:

  • Basin wrench
  • Adjustable wrenches
  • Bucket
  • Putty knife
  • Old rags or towels
  • Bathroom faucet
  • Supply lines
  • Silicone caulk
  • Mineral spirits, optional

Step 1: Turn off the water supply valves under the sink. If you don’t see valves under the sink, turn off the main water valve. Then turn on the faucet to relieve any remaining water pressure in the lines.

Step 2: Disconnect the supply lines from the faucet (use a basin wrench if you can’t reach the connections with your hands).

Step 3: Disconnect the lift rod, and then remove the nuts from under the faucet. Now that the faucet has been removed, you will now remove the drain.

Step 4: Unscrew the slip nut on the P-trap. Place a bucket underneath to catch water in the trap.

Step 5: Disconnect the drain flange from the tailpiece (it should unscrew).

Step 6: Clean around the old drain and faucet holes. If needed, mineral spirits can help remove old silicone sealant. Now you’re ready to install the new faucet.

Step 7: Be sure to follow the manufacturer’s instructions for installation. Most installations begin with installing the gasket on the bottom of the faucet. Some require sealant or plumber’s putty. Then put the faucet through the mounting holes in the sink and tighten the mounting nuts.

Step 8: Not all faucets come preassembled, so you may have to attach the handles, which is simple. Just slip the guide ring onto the bottom of the handle, positions it on the faucet base and secure with the setscrew (this is the tiny screw on the underside of the handle). Most faucets come with a hex wrench to tighten the setscrew.

Step 9: Next is the drain — screw the nut all the way down on the drain body and push the gasket over it. Some gaskets are threaded and simply screw into place.

Step 10: Apply just a little bit of silicone caulk (check your packaging as some manufacturers recommend plumber’s putty) under the flange. Position the drain body on the bottom of the sink, making sure the pivot hole is facing the back, and screw the flange on from the top side.

Step 11: Underneath the flange, tighten the nut and gasket. Use mineral spirits to clean up any excess silicone on the top of the flange.

Step 12: Install the drain rod next. Unscrew the pivot nut on the drain body, insert the horizontal rod through the hole in the stopper, and replace the nut. Push the horizontal rod down and secure the lift rod to the strap with the screw. Test the lift rod.

Step 13: Reconnect the supply line to the faucet. If your sink is already in place, use a basin wrench to reach the faucet shanks.

Step 14: Flush the faucet by removing the aerator (this gets rid of debris or sediment in the faucet). Some faucets include a handy little tool to unscrew the aerator. Now turn on the hot and cold water for about a minute. Check all the connections for leaks and retighten if necessary. Then screw the aerator back on.

Please note that when buying a faucet, you need to make sure it will fit your sink. Your sink will have one, two or three holes for the faucet. Plus, the holes will be either center-set or widespread. Make sure you have this information when you’re shopping. When in doubt, take the old faucet to the store with you!
