Product Overview
The Hamat SIO-3319SU-BL is a 33-inch SiOStone granite-composite kitchen sink with an undermount rim, a large single bowl, and a black finish. The open bowl gives home cooks and busy households room for cookware, baking sheets, serving pieces, food preparation, and everyday cleanup. Its 9-1/2-inch depth helps contain water and larger items, while the undermount installation creates a smooth countertop-to-bowl transition that makes it easier to wipe crumbs and spills directly into the sink.
The sink measures 33 inches wide by 18-7/8 inches front to back and uses a rear-set drain. Positioning the drain toward the back keeps more of the central bowl floor open and can help keep the drain assembly closer to the rear cabinet wall. Hamat specifies a 36-inch minimum base cabinet. Because this is an undermount sink, the countertop material, reveal style, cutout, clips, adhesive, and support method must be planned before fabrication. The black color creates strong contrast with light counters and coordinates with matte-black, graphite, stainless-steel, and mixed-metal fixtures.
