Whats the difference between an undermount or overmount sink?
An undermount sink sits below the cutout in the granite or marble. The stone overlaps part of the sink’s rim, which provides for very easy care and maintenance. A topmount sink sits above the granite or marble with a lip or flange of the sink overlapping the stone. See examples: A drop in sink has a lip that folds over the countertop and is therefore resting on top of the cutout. Fasteners underneath the countertop securely mount an “undermount” sink so that a polished edge of granite, marble etc. is exposed above the sink. An undermount sink cutout requires more polishing and installation labor than a drop-cutout and is therefore a more expensive option. Click picture below to see different mounting styles!
