How to Replace an Old Bathroom Sink Faucet

Replacing an old bathroom sink faucet can be a simple and rewarding DIY project. It can enhance the appearance of your bathroom, improve functionality, and potentially save you money on water bills with more efficient fixtures. While different faucet models may have slight variations, this guide provides a general overview of the process with steps applicable to most standard bathroom sink faucets.

Step 1: Gather Tools and Materials

Before embarking on the project, gather the necessary tools and materials. This will ensure a smooth and efficient process. You will need:

New bathroom sink faucet
Adjustable wrench
Channel-lock pliers
Phillips head screwdriver
Flathead screwdriver
Plumber's tape (Teflon tape)
Bucket
Rag or towel
Safety glasses
Optional: Basin wrench

Step 2: Turn Off the Water Supply

Safety is paramount during any plumbing project. Before disassembling anything, turn off the water supply to the sink. Locate the shut-off valves beneath the sink or in the basement or utility room. Turn the valves completely clockwise until they stop. Verify that the water is shut off by turning on the faucet and checking for water flow.

Step 3: Drain the Water Lines

With the water turned off, open the faucet to drain any remaining water in the lines. This will prevent water from spilling during the disassembly process. You can also use a bucket to catch any excess water that may drain from the supply lines.

Step 4: Disconnect the Old Faucet

Now, it's time to remove the old faucet. Begin by disconnecting the supply lines. Using adjustable wrenches, carefully loosen the nuts connecting the supply lines to the faucet. If you have a basin wrench, it can be helpful in reaching those hard-to-access nuts. Once the supply lines are disconnected, remove the decorative escutcheons (cover plates) that conceal the mounting nuts.

Underneath the escutcheons, you will find the mounting nuts. These are typically brass nuts that hold the faucet in place. Use your adjustable wrenches to loosen and remove these nuts. The faucet should now detach from the sink.

Step 5: Clean the Sink and Drain

Now that the old faucet is removed, take this opportunity to clean the sink and drain area. Remove any debris or mineral deposits that may have accumulated over time. This will ensure a clean and fresh installation for the new faucet.

Step 6: Install the New Faucet

The installation of the new faucet mirrors the steps of the old one, but in reverse. Start by applying plumber's tape to the threads of the supply lines. This tape helps create a watertight seal and prevents leaks. Connect the supply lines to the new faucet, ensuring the proper orientation (hot on the left, cold on the right). Tighten the connecting nuts securely but avoid overtightening, as this can damage the threads.

Next, place the faucet on the sink and align the mounting holes. Insert the mounting bolts through the holes in the faucet and secure them with the mounting nuts, found underneath the sink. Tighten the nuts firmly, making sure the faucet is securely fastened.

Finally, attach the decorative escutcheons to cover the mounting nuts. Install the handle(s) according to the instructions provided with your new faucet. Ensure all parts are securely fastened before proceeding to the next step.

Step 7: Turn On the Water Supply

Slowly turn the water supply valves back on, starting with the cold water valve. Check for any leaks at the connection points. If there are leaks, tighten the connections further or reapply plumber's tape. Repeat the process with the hot water valve. Once all connections are secure, test the faucet by turning it on and off, checking for proper water flow and temperature regulation.

Congratulations! You have successfully replaced your old bathroom sink faucet. As you enjoy the fruits of your labor, consider taking a few extra steps. Wipe down any excess water or plumbing tape, and dispose of the old parts responsibly. Now, your bathroom sink is ready to serve you well for years to come.
