Product Overview
The Hamat SIO-2420ST-BL is a compact SiOStone granite-composite kitchen sink with a topmount rim, a single bowl, and a black finish. Its 23-5/8-inch width makes it useful for kitchens, prep areas, bars, utility spaces, and remodels where a full-size 30- or 33-inch sink is not practical. The 7-7/8-inch bowl depth provides everyday space for rinsing produce, washing dishes, filling containers, and handling routine cleanup without requiring an oversized sink base.
The sink measures 23-5/8 inches wide by 20 inches front to back and uses a rear-set drain. Moving the drain toward the back helps keep more of the central bowl floor open while allowing the under-sink plumbing to remain closer to the rear of the cabinet. Hamat specifies a 27-inch minimum base cabinet. The sink includes one pre-drilled faucet hole and four additional pre-scored locations, allowing the installer to plan for a faucet and compatible accessories without opening every position. The black color creates strong contrast against light counters and cabinets while coordinating with matte-black, graphite, stainless-steel, or mixed-metal fixtures. Confirm the cabinet width, countertop opening, selected faucet-hole locations, drain connection, and exact color before ordering or cutting the counter.
