Replacement Sink For Bathroom Vanity

Replacing a bathroom vanity sink is a relatively straightforward project that can be completed in a few hours with the right tools and materials. Here are the steps on how to replace a bathroom vanity sink:

1. Gather the necessary tools and materials

New bathroom sink
Basin wrench
Adjustable wrench
Plumber's putty or silicone caulk
Putty knife
Bucket
Rags

2. Turn off the water supply to the sink

Locate the water supply valves under the sink and turn them off. If there are no valves, you will need to turn off the main water supply to the house.

3. Disconnect the water supply lines

Use an adjustable wrench to loosen the nuts that connect the water supply lines to the sink. Be careful not to overtighten the nuts, as this can damage the lines.

4. Remove the old sink

Place a bucket under the sink to catch any water that drains out. Use a putty knife to remove the old plumber's putty or silicone caulk around the base of the sink. Once the old caulk is removed, carefully lift the sink out of the vanity.

5. Clean the vanity top

Use a cleaner and a damp rag to clean the vanity top where the new sink will be installed. Make sure to remove any old caulk or debris.

6. Apply a bead of plumber's putty or silicone caulk

Apply a bead of plumber's putty or silicone caulk around the rim of the new sink. Make sure to apply the caulk evenly and smoothly.

7. Set the new sink in place

Carefully set the new sink in place on the vanity top. Make sure that the sink is centered and level. Press down on the sink around the edges to ensure that the caulk is making a good seal.

8. Reconnect the water supply lines

Use an adjustable wrench to tighten the nuts that connect the water supply lines to the sink. Be careful not to overtighten the nuts, as this can damage the lines.

9. Turn on the water supply and check for leaks

Turn on the water supply to the sink and check for any leaks. If you see any leaks, tighten the nuts on the water supply lines until the leaks stop.

10. Finish the installation

Once the sink is installed and there are no leaks, you can finish the installation by caulking around the edges of the sink. Use a caulk gun to apply a bead of caulk around the sink and smooth it out with your finger.
