How To Replace Undermount Sink

Replacing an undermount sink can be a challenging but rewarding task. Undermount sinks are installed beneath the countertop, which gives them a sleek and modern look. However, this also makes them more difficult to replace than top-mount sinks. If you're planning on replacing your undermount sink, here's a step-by-step guide to help you get the job done.

Step 1: Gather Your Tools and Materials

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

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

Step 2: Remove the Old Sink

Once you have your tools and materials, you can begin removing the old sink. To do this, follow these steps:

Turn off the water supply to the sink.
Disconnect the water lines from the sink.
Disconnect the drain line from the sink.
Loosen the screws that are holding the sink in place.
Carefully remove the sink from the countertop.

Step 3: Clean the Countertop

Once the old sink is removed, you'll need to clean the countertop. This will ensure that the new sink will adhere properly. To clean the countertop, use a sponge and a mild detergent. Rinse the countertop with clean water and allow it to dry completely.

Step 4: Apply Plumber's Putty

Once the countertop is clean and dry, you can apply plumber's putty to the rim of the new sink. Plumber's putty is a pliable material that will help to seal the sink to the countertop. To apply plumber's putty, simply roll it into a rope and place it around the rim of the sink.

Step 5: Install the Sink

Once the plumber's putty is in place, you can install the new sink. To do this, carefully lift the sink into place and align it with the countertop. Once the sink is in place, press down firmly to secure it. Use a wrench to tighten the screws that are holding the sink in place.

Step 6: Reconnect the Water Lines

Once the sink is installed, you can reconnect the water lines. To do this, simply screw the water lines onto the sink. Make sure to tighten the connections securely.

Step 7: Reconnect the Drain Line

Next, you'll need to reconnect the drain line. To do this, simply attach the drain line to the sink and tighten the connection.

Step 8: Caulk Around the Sink

Once the sink is installed and the water and drain lines are reconnected, you can caulk around the sink. To do this, simply apply a bead of caulk around the perimeter of the sink. Use a caulk gun to apply the caulk evenly.

Step 9: Remove Excess Caulk

Once the caulk is applied, you'll need to remove any excess caulk. To do this, simply use a damp sponge to wipe away the excess caulk. Allow the caulk to dry completely before using the sink.

Step 10: Turn on the Water Supply

Once the caulk is dry, you can turn on the water supply to the sink. Check for any leaks. If you find any leaks, tighten the connections until the leak stops.
