How To Remove Old Undermount Bathroom Sink

Removing an old undermount bathroom sink may seem daunting, but it is a manageable task most DIYers can complete with the right tools and a bit of patience. Here's a step-by-step guide to help you remove your old undermount bathroom sink safely and efficiently:

Step 1: Gather Your Tools and Materials Before you start, gather the necessary tools and materials, including a bucket, a wrench, a putty knife, a utility knife, a flashlight, and a pair of gloves. Consider safety first by putting on your gloves and safety glasses if available.

Step 2: Turn Off the Water Supply Locate the shut-off valves for the hot and cold water supply lines under the sink and turn them clockwise to close them completely. Open the faucets to release any remaining water in the lines.

Step 3: Disconnect the Water Supply Lines Use a wrench to disconnect the water supply lines from the sink's faucet. If the connections are old or rusted, you may need to use a penetrating oil to loosen them gently. Place a bucket under the connections to catch any dripping water.

Step 4: Disconnect the Drain Use a putty knife to carefully cut away the old plumber's putty around the drain flange. Loosen the slip nut holding the drain in place and remove the drain assembly.

Step 5: Remove the Sink Clips Use a utility knife to cut through any sealant around the sink's perimeter. Locate the sink clips, usually metal brackets securing the sink to the countertop, and unclip them. Carefully remove the old sink and lift it out of the countertop.
