Product Overview
The Hamat SIO-3319DU-BL is a 33-inch SiOStone granite-composite undermount kitchen sink with two equal-size bowls, a low-wall center divider, and a black finish. The 50/50 layout provides separate compartments for washing, rinsing, soaking, food preparation, or keeping clean and dirty items apart. Its lower divider maintains separation between the bowls while making it easier to move long cookware, baking sheets, and oversized utensils across the center than a conventional full-height divider.
The sink measures 33 inches wide by 18-1/2 inches front to back with a 9-1/2-inch depth and rear-set drains. Hamat specifies a 36-inch minimum base cabinet. The undermount rim creates a smooth countertop-to-bowl transition, but the countertop material, cutout, reveal style, clips, adhesive, and structural support must be planned before fabrication. The black SiOStone finish creates strong contrast with light countertops and coordinates with matte-black, graphite, stainless-steel, and mixed-metal fixtures. Confirm the cabinet opening, countertop compatibility, reveal preference, drain and disposal layout, faucet placement, and exact color before ordering or cutting the counter.

FAQ
Are both bowls the same size?
Yes. The sink uses a 50/50 equal-bowl configuration.
What is the purpose of the low divider?
It separates the bowls while allowing longer cookware and baking sheets to extend across the center more easily.
Are the grids included?
The CWG-1315L and CWG-1315R grids are optional unless the product listing explicitly states that they are included.
What should I verify before ordering?
Confirm the SIO-3319DU-BL SKU, black finish, cabinet width, countertop material, reveal style, support plan, and plumbing layout.
