Product Overview
The Hamat SIO-3322DATR-BL is a 33-inch SiOStone granite-composite topmount kitchen sink with rounded offset bowls, a 60/40 layout, a 4-inch low divider, and a black finish. The larger bowl provides space for cookware, baking sheets, food preparation, and everyday cleanup, while the smaller bowl can remain available for rinsing, soaking, or separating tasks. The rounded bowl transition and low center divider make it easier to maneuver larger items across the sink than a traditional offset double bowl with a full-height partition.
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 one pre-drilled faucet hole plus four additional pre-scored locations, allowing the installer to open only the positions needed for the 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, large-bowl orientation, faucet-hole plan, drain and disposal locations, and exact color before ordering.

FAQ
What is the benefit of the 4-inch low divider?
It keeps the bowls separate while allowing large cookware and baking sheets to extend across the center more easily.
Are the bowls equal in size?
No. This is a rounded 60/40 configuration with one larger bowl and one smaller bowl.
Are the bottom grids included?
The CWG-1517 and CWG-1115 grids are optional unless the product listing explicitly states otherwise.
What should I verify before ordering?
Confirm the SIO-3322DATR-BL SKU, black color, cabinet width, bowl orientation, faucet-hole layout, drain connections, and optional accessories.
