The Karran Matrix is a 33-inch top-mount single-bowl kitchen sink in a Gunmetal Grey finish, built from 16-gauge stainless steel for a workstation-ready install that drops into an existing countertop cutout.
A single-bowl layout gives the full 30-inch interior length for tasks where a divider gets in the way: rinsing a stock pot, washing a cutting board flat, or handling sheet pans without tipping them. The top-mount install means this sink seats into a countertop cutout from above, so it fits laminate, quartz, granite, and solid surface without special adhesive bonding or below-counter support work. The rim rests on the counter surface and the mounting clips secure it from underneath, keeping the job straightforward for a remodel or a countertop replacement where the cutout is already there.
At 16 gauge, the steel is thicker than the 18-gauge sheets used in many residential kitchen sinks at this price tier. The added thickness reduces flex under load and helps dampen sound when the basin is in use. The Gunmetal Grey finish sets this sink apart from the more common brushed or polished stainless options: the matte dark-toned surface reads as a design choice rather than a default, and it holds up to fingerprints and water spots better than a bright-polished finish in a busy kitchen. The 33 x 22-inch overall footprint fits standard 33-inch base cabinet openings.
This is the right sink for a kitchen remodel or new build where the countertop supports top-mount installation and the design calls for something other than standard brushed silver. The Gunmetal Grey finish works well with matte black or dark-toned hardware, dark stone countertops, and two-tone cabinet schemes where a darker accent makes sense. It also suits a kitchen island or a prep station where a single open bowl gets daily hard use and the top-mount rim keeps the install simple. Cabinet shops and contractors building custom kitchens can spec this sink confidently into any 33-inch base cabinet without needing a special farmhouse or undermount cabinet modification.
The matte Gunmetal Grey finish is more forgiving of water spots and fingerprints than a polished stainless surface. A dry wipe after use keeps it looking clean.
In most cases, yes. A 33-inch top-mount sink drops into a standard 33-inch cutout, so it fits a countertop that already has that opening. Confirm the existing cutout dimensions match the 33 x 22-inch footprint before ordering.
The Matrix is Karran's workstation series, meaning the sink is designed to support compatible workstation accessories such as colanders, cutting boards, and grids that sit across or inside the bowl. Check the Karran Matrix accessory line for compatible add-ons.
The drain opening is 3-1/2 inches, which accepts standard basket strainers and garbage disposal flanges. Drain hardware is sold separately.
The Karran Matrix in Gunmetal Grey brings a deliberate finish choice and a thick 16-gauge single bowl to a top-mount install that works with the countertop you already have.
