The Karran Matrix is a 16-gauge stainless steel undermount kitchen sink in a Gunmetal Grey finish, sized at 32 inches wide with a single deep rectangular bowl for everyday kitchen work.
A single bowl this size gives uninterrupted basin space from side to side, which matters when you are fitting a large roasting pan, a tall stockpot, or a full sheet tray under the faucet. There is no center divider to work around. The 9-inch bowl depth keeps water and splashing contained even with deep fills. For a kitchen where one bowl does all the work, the Matrix holds its own.
Gunmetal Grey is a darker, muted finish applied over the stainless surface, distinct from standard brushed silver and from polished chrome. It pairs well with darker hardware, black fixtures, and matte cabinet finishes in contemporary and transitional kitchens. The 16-gauge steel body is thicker than 18-gauge and adds rigidity and sound mass to the bowl. The rectangular form and clean interior keep the look simple and utilitarian.
This is a practical choice for a kitchen remodel or new build where the countertop is being fabricated and the designer or builder wants a single large bowl that does not compete with the hardware finish. It suits contractors specifying stainless sinks for contemporary kitchens with dark or matte-finish fixtures, designers building around a cohesive gunmetal or matte black palette, and homeowners who want a workhorse kitchen sink that does not show the wear a bright finish would. Because it is an undermount, it requires a countertop material that supports undermounting and a new or freshly cut opening sized to the bowl's 32-inch exterior width.
Gunmetal Grey is a darker, matte-toned finish applied to the stainless surface. A standard brushed stainless bowl reads as silvery grey; Gunmetal Grey reads closer to charcoal and coordinates with darker or matte hardware finishes.
Gauge refers to the steel's thickness. At 16 gauge, this sink's steel is thicker than an 18-gauge bowl, which means it is more rigid, dents less easily, and dampens sound better under running water.
Undermount sinks generally require a countertop that supports the mounting method, such as quartz, granite, or solid surface. Confirm that your countertop material and existing or planned cutout dimensions match the 32-inch exterior width before ordering.
The drain opening is 3-1/2 inches, which accepts standard basket strainers and disposal flanges sold separately.
Choose the Karran Matrix in Gunmetal Grey for a single-bowl undermount sink that brings a darker, contemporary finish to a 16-gauge stainless workstation sized for real kitchen use.
