Why Choose an Undermount Sink?

As an undermount kitchen sink, the Quantum kitchen sink uses clips to mount to the underside of your countertop. This makes for an great contemporary look. This sink also allows you to easily wipe debris into the sink, making cleanup as easy as it gets. However, an undermount sink is more difficult to install – the cutout in the counter needs to fit perfectly so you need ot make sure the sinks dimensions fit your countertops cutout or have your new countertop cut to fit the dimensions of the sink.

Why Choose a Granite Sink?

Granite composite is beautiful and is available in a variety of colors. This material handles very high heats, so putting a hot pan in the bowl is no big deal. The material is also stain and scratch resistant.
