Step 3 · Remove the Old Sink

This is the step most people slow down on. Take it one move at a time — there’s no rush, and you can rewind the clip as many times as you need.

The old sink is held in place by a combination of silicone adhesive and metal mounting clips. First, use a utility knife to carefully slice through the silicone bead between the sink rim and the underside of the countertop. Be thorough and cut all the way around. Next, locate the mounting clips screwed into the countertop's underside. Use a screwdriver or socket wrench to loosen and remove all of these clips. Have your helper support the sink from below, or create a support brace using a 2x4 and a bar clamp. Once all clips are removed and the silicone is cut, carefully lower the old sink and remove it from the cabinet.
