How to Change a Faucet in the Bathroom Sink: A Comprehensive Guide

A leaky or outdated faucet can not only be annoying, but it can also waste water and lead to higher water bills. Fortunately, changing a faucet is a relatively simple plumbing project that can be completed in a few hours with the right tools and materials.

In this guide, we'll provide step-by-step instructions on how to change a bathroom sink faucet. Whether you're a seasoned DIYer or a complete novice, we'll make sure you have all the information you need to get the job done right.

Step 1: Gather Your Tools and Materials

Before you begin, gather the following tools and materials:

New bathroom sink faucet
Adjustable wrench or basin wrench
Phillips head screwdriver
Flathead screwdriver
Plumber's putty
Rags or towels

Step 2: Turn Off the Water Supply

Safety first! Before you start working on the faucet, shut off the water supply lines under the sink. There should be two separate valves, one for hot water and one for cold water. Turn both valves clockwise until they are fully closed.

Step 3: Disconnect the Water Supply Lines

Use an adjustable wrench or basin wrench to loosen the nuts that connect the water supply lines to the old faucet. Be careful not to overtighten or you may damage the lines.

Step 4: Remove the Old Faucet

Once the water supply lines are disconnected, you can remove the old faucet. There will be a nut or bolts that secure the faucet to the sink. Use a wrench or screwdriver to loosen and remove these fasteners.

Step 5: Clean the Sink and Mounting Surface

Before installing the new faucet, clean the sink and mounting surface thoroughly. Remove any old plumber's putty or debris. This will help ensure a good seal for the new faucet.

Step 6: Apply Plumber's Putty

Roll a small piece of plumber's putty into a rope and apply it around the base of the new faucet. This will help create a watertight seal between the faucet and the sink.

Step 7: Install the New Faucet

Place the new faucet over the mounting surface and align it with the water supply lines. Tighten the nuts or bolts that secure the faucet to the sink.

Step 8: Reconnect the Water Supply Lines

Hand-tighten the nuts that connect the water supply lines to the new faucet. Then, use a wrench to tighten them another 1/4 to 1/2 turn. Be careful not to overtighten.

Step 9: Turn On the Water Supply

Slowly turn on the water supply valves under the sink. Check for any leaks around the faucet base or the water supply lines. If you see any leaks, tighten the connections accordingly.

Step 10: Test the Faucet

Turn on the faucet and check for leaks. Adjust the water temperature and flow rate as desired. If everything is working properly, congratulations! You've successfully changed your bathroom sink faucet.
