How to Install an Undermount Kitchen Sink · Step 2 of 10
In this video
With the plumbing disconnected, you can remove the disposal unit itself. First, support the unit from underneath with your hands, a bucket, or a block of wood, as it is heavy. Locate the metal mounting ring at the very top of the disposal, where it connects to the sink flange. Grip the ring or its tabs and rotate it counter-clockwise. This will unlock the disposal from the mount. Once unlocked, carefully lower the unit and remove it from under the sink.
Goal: Detach and remove the disposal unit
- If the ring is stuck, you can insert a screwdriver into one of the tabs for extra leverage to help turn it.

FAQs
What specialized tools are essential for installing an undermount sink that I might not already own?
You'll definitely need a basin wrench for reaching tight plumbing nuts, a quality caulk gun for sealant application, and sturdy bar clamps (like the BESSEY Clutch Style) to hold the sink firmly in place while the adhesive cures. These ensure a secure and watertight installation.
What are the most critical safety steps to take when removing the old sink and working with plumbing?
Always turn off the water supply to the sink completely before starting. Keep a bucket and towels handy for residual water, and if a garbage disposal is present, ensure its power is disconnected at the circuit breaker to prevent accidental activation and electrical hazards.
The project is rated 'beginner' with an 8-hour estimate; is this realistic for someone with limited DIY experience?
While rated beginner, 8 hours is an optimistic estimate for a first-timer. Plan for a full day or even two half-days to account for unexpected plumbing issues, meticulous dry-fitting, and allowing adequate adhesive curing time. Don't rush the sealing and clamping steps.
What common mistakes should I watch out for to ensure a leak-free and secure undermount sink installation?
The most common mistakes are insufficient adhesive/sealant, improper clamping leading to gaps, and not allowing enough curing time for the sealant. Ensure a continuous, thick bead of 100% silicone around the sink rim, use all recommended mounting clips, and keep the sink firmly clamped until the adhesive is fully cured.
