Step 2: Turn Off the Water Supply

Step 4: Remove the Old Sink

1. Use a utility knife to cut through any sealant or caulk around the edge of the sink.

3. Carefully lift the old sink out of the countertop. You may need a helper for this step, especially if the sink is heavy.

Step 5: Prepare the Area

Step 6: Install the Faucet on the New Sink

1. Follow the manufacturer’s instructions to install the faucet onto the new sink.

2. Use plumber's tape on the faucet threads for a secure, leak-proof connection.

3. Apply a bead of plumber's putty around the faucet base before securing it to the sink.
