This undermount sink is constructed of high quality 18 gauge SUS304 Stainless Steel. It is a stylish and practical addition to your kitchen with its offset bowls - large (left) bowl measuring 17-3/4'' L x 18-1/2'' W x 9'' D, and small (right) bowl measuring 10-1/2'' L x 16'' W x 7'' D. This sink features extra insulation to aid in sound dampening and reinforced plates to ensure the sink will stand the test of time. The brushed satin finish helps camouflage small scratches that could appear overtime with daily use and the offset drain with a diameter of 3.5'' helps with quick drainage. The sink strainer (STRAINER-200) is sold separately.
