How To Replace A Bathroom Undermount Sink

Replacing an undermount bathroom sink is a relatively straightforward project that can be completed in a few hours. Here's a step-by-step guide to help you get the job done:

Step 1: Gather your materials

Before you begin, you'll need to gather the following materials:

New undermount sink
New sink mounting clips
Plumber's putty
Caulk gun and caulk
Wrench or pliers
Utility knife

Step 2: Remove the old sink

To remove the old sink, first turn off the water supply to the bathroom. Then, disconnect the water lines from the sink and remove the sink mounting clips. Once the clips are removed, you should be able to lift the sink out of the countertop.

Step 3: Clean the countertop

Once the old sink is removed, take some time to clean the countertop. Wipe down the surface with a damp cloth to remove any dirt or debris. This will help ensure that the new sink adheres properly to the countertop.

Step 4: Apply plumber's putty

Before installing the new sink, you'll need to apply a bead of plumber's putty around the rim of the sink. This will help to seal the sink to the countertop and prevent leaks.

Step 5: Install the new sink

Once the plumber's putty is in place, carefully lower the new sink into the countertop. Align the sink with the mounting holes and press down firmly to seat the sink in the putty. Once the sink is in place, install the sink mounting clips to secure the sink to the countertop.

Step 6: Reconnect the water lines

Once the sink is installed, reconnect the water lines. Tighten the nuts on the water lines until they are snug, but do not overtighten.

Step 7: Caulk around the sink

To finish the installation, caulk around the perimeter of the sink where it meets the countertop. This will help to seal the sink to the countertop and prevent leaks.
