Product Overview
The Hamat SIO-3322DTR-BL is a 33-inch SiOStone granite-composite kitchen sink with a topmount rim, a 60/40 double-bowl layout, and a black finish. The offset bowl configuration provides one larger working bowl for cookware, food preparation, and everyday cleanup, plus a smaller bowl that can remain available for rinsing, soaking, or separating kitchen tasks. This arrangement offers more room for larger items than an equal-bowl sink while retaining the convenience of two independent compartments.
The sink measures 33 inches wide by 22 inches front to back with a 9-1/2-inch depth and rear-set drains. Hamat specifies a 36-inch minimum base cabinet. The deck includes four pre-scored faucet and accessory locations; these positions are not all pre-drilled, allowing the installer to open only the locations needed for the selected faucet, soap dispenser, air gap, or other compatible accessories. The black SiOStone finish creates strong contrast against light countertops and cabinets while coordinating with matte-black, graphite, stainless-steel, and mixed-metal fixtures. Confirm the cabinet width, countertop cutout, bowl orientation, faucet-hole plan, drain connections, disposal location, and exact color before ordering or cutting the counter.
