​Removing an undermount sink looks simple from above, but the sink is usually held in place by a combination of silicone adhesive, mounting clips, rails, or a support frame beneath the countertop. If you remove it the wrong way, you can crack stone, chip the cutout edge, damage plumbing, or deform the sink rim.

​Measuring correctly for an undermount sink is one of the most important steps before ordering or fabricating a countertop. Unlike top-mount sinks, an undermount sink is installed beneath the countertop surface, which means the cabinet opening, countertop cutout, and sink dimensions must work together precisely.

​Installing a top mount sink on granite countertops is a common solution in residential kitchens, rental properties, and commercial projects where durability, serviceability, and installation efficiency are priorities.

​An undermount apron sink combines two demanding installation requirements in one system. The sink must be supported structurally from the cabinet, while the rim must align precisely under the countertop cutout, and the apron front must sit cleanly against the cabinet face with the correct reveal.
