Undermounted Sinks

An undermounted sink can be one of the most striking features of a new custom countertop.

Whether the countertop is fabricated from granite, engineered stone or solid surface material virtually any sink can be undermounted. There are certain basic guidelines that must be followed.

Since undermounted sinks are supported by brackets mounted within the sinkbase cabinet, the cabinet has to be large enough to accommodate the sink and mounting brackets. If the not the cabinet side panels will have to be modified to accommodate the width of the sink.

Having the proper cabinet depth is also vital. Undermounted sinks use the countertop itself as the faucet deck so there must be enough room behind the sink for the faucet assembly to operate properly. This is especially true when 3 cm backsplash is being installed.

Sink manufacturers determine whether or not their sinks are suitable for undermounting. Though most sinks can be undermounted there are a few exceptions. The flange surrounding the sink must be flat. SSD will not undermount sinks with double or exaggerated rolled edges because they lack sufficient surface to apply silicone for proper adhesion and sealing. We also discourage undermounting stainless steel sinks with integrated faucet decks.

Farm or apron sinks are usually undermounted, however; there are new cast/composite apron sinks on the market that can be top mounted. As a rule farm sinks must be plumbed into the cabinet before templating. The top of the sink rim must be set flush with the face frame and cabinet sides and back to allow the countertop surface to lay flat.

In 1993 Solid Surface Designs, Inc., began business as a factory certified fabricator-installer for DuPont Corian. Since then we have grown to become the region's largest fabricator and installer of Granite, Quartz and Solid Surface countertops.
