The SOLO Collection Undermount Sinks from Nantucket Sinks are single-bowl sinks made of 18-gauge or 16-gauge 304 series stainless steel. The sinks are available in several rectangular shapes as well as in a round configuration, and can be installed under any solid surface. Equipped with a sound-deadening rubber padding to reduce noise, the sinks have a Satin finish and come with a mounting kit, a strainer and a cardboard cut-out. Optional bottom grids are available for the NT-KS1415, NT-KS1413 and the NT-KS1410 rectangular sinks.
