Hamat – SIO-3319DU-WH – Granite Undermount 50/50 Double Bowl Kitchen Sink, White

Product Overview

The Hamat SIO-3319DU-WH is a 33-inch SiOStone granite-composite undermount kitchen sink with two equal-size bowls, a low-wall center divider, and a white 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 two working 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, mounting hardware, adhesive, and structural support must be planned before fabrication. The white finish creates a bright, clean appearance that can blend with pale counters and cabinets or provide crisp contrast against dark surfaces and hardware. Confirm the cabinet opening, countertop compatibility, reveal preference, drain and disposal layout, faucet placement, and exact color before ordering.

FAQ

Are both bowls the same size?

Yes. This model uses a 50/50 equal-bowl configuration.

Why is the divider lower than a standard double-bowl sink?

The low divider keeps separate compartments while allowing longer items to extend across the center more easily.

Are the grids included?

The CWG-1315L and CWG-1315R grids are optional unless the listing explicitly states otherwise.
