How To Replace Vanity Sink

Replacing a vanity sink is a relatively simple plumbing project that can be completed in a few hours. By following these step-by-step instructions, you can save yourself the cost of hiring a plumber.

Step 1: Gather Your Tools and Materials

Before you begin, gather the following tools and materials:

New vanity sink
Wrench
Pliers
Screwdriver
Caulk gun
Caulk
Plumber's putty
Bucket

Step 2: Turn Off the Water Supply

Locate the water supply valves under the sink. Turn off both the hot and cold water valves by turning them clockwise.

Step 3: Disconnect the Water Lines

Use a wrench to disconnect the water lines from the faucet. Be sure to place a bucket under the connections to catch any water that may leak out.

Step 4: Remove the Old Sink

Once the water lines are disconnected, you can remove the old sink. First, loosen the nuts that hold the sink in place. Then, carefully lift the sink out of the vanity.

Step 5: Clean the Vanity

Before installing the new sink, take a moment to clean the vanity. Remove any old caulk or debris from the area where the sink will be installed.

Step 6: Install the New Sink

Place the new sink in the vanity. Center the sink and then tighten the nuts that hold it in place. Be sure not to overtighten the nuts, as this could damage the sink.

Step 7: Connect the Water Lines

Connect the water lines to the faucet. Be sure to use plumber's putty to seal the connections. Tighten the nuts on the water lines until they are snug.

Step 8: Turn On the Water Supply

Turn on the water supply valves under the sink. Check for any leaks at the connections. If you find any leaks, tighten the nuts on the water lines until the leaks stop.

Step 9: Caulk Around the Sink

Caulk the area around the sink to prevent water from leaking out. Apply a bead of caulk to the joint between the sink and the vanity. Smooth the caulk with your finger or a caulk tool.
