How To Replace Undermount Sink Without Removing Countertop

Replacing an undermount sink without removing the countertop is a challenging but doable task. Here's a step-by-step guide to help you through the process:

1. Gather Your Tools

Before you start, gather the following tools:

Putty knife
Utility knife
Caulk gun
Caulk
New sink
Sink clips

2. Remove the Old Sink

Start by using a putty knife to cut the caulk around the sink's edge. Once the caulk is cut, use a utility knife to carefully score the silicone sealant around the sink's perimeter. Be careful not to cut into the countertop.

Once the silicone is scored, use the putty knife to pry the sink loose from the countertop. Be careful not to damage the countertop or the sink.

3. Clean the Countertop

Once the old sink is removed, clean the countertop thoroughly. Remove any remaining caulk or silicone sealant. The countertop must be clean and dry before installing the new sink.

4. Install the Sink Clips

Place the sink clips around the perimeter of the countertop opening. The clips will help to support the new sink. Make sure the clips are evenly spaced and securely attached.

5. Apply the Caulk

Apply a bead of caulk around the perimeter of the sink opening. The caulk will help to seal the sink to the countertop and prevent leaks.

6. Install the New Sink

Carefully place the new sink into the countertop opening. Align the sink with the clips and press down firmly to seat it. Make sure the sink is level and properly aligned.

7. Tighten the Clips

Once the sink is in place, tighten the clips to secure it. Make sure the clips are tight enough to hold the sink in place but not so tight that they damage the sink or the countertop.
