Product Overview
The Hamat SIO-3321ST-BL is a 33-inch SiOStone granite-composite kitchen sink with a topmount rim, an extra-large single bowl, and a black finish. Its generous bowl gives home cooks, entertainers, and busy households room for large cookware, baking sheets, serving pieces, food preparation, and everyday cleanup. The 9-1/2-inch depth helps contain water and larger items while maintaining a familiar drop-in installation style.
The sink measures 33 inches wide by 22 inches front to back and uses a rear-set drain. Positioning the drain toward the rear keeps more of the central bowl floor open and can allow the under-sink drain assembly to remain closer to the cabinet wall. Hamat specifies a 36-inch minimum base cabinet. The deck has one pre-drilled faucet hole and four additional pre-scored locations, allowing the installer to select only the openings needed for the faucet, soap dispenser, air gap, or other compatible accessories. The black color provides strong contrast against light counters and cabinets while coordinating with matte-black, graphite, stainless-steel, or mixed-metal fixtures. Confirm the cabinet width, countertop cutout, faucet-hole plan, drain connection, and exact color before ordering or cutting the counter.
