The Karran Matrix is a 16-gauge stainless steel undermount kitchen sink finished in Gunmetal Grey, with two equally sized bowls that mount beneath a solid countertop for a clean, rimless surface line.
Two equally sized bowls mean one side can hold a soaking pot while the other stays open for rinsing produce or washing glassware. Neither bowl is the secondary half of an uneven split, so the sink works the same way regardless of which side you favor. The 9-inch depth gives enough room for tall stockpots and sheet pans without the bowls feeling excessively deep for everyday tasks.
The Gunmetal Grey finish sets this sink apart from the standard brushed and polished stainless options. It reads as a deeper, cooler-toned grey that pairs naturally with matte black or dark bronze hardware and works well against both light and dark countertop materials. The 16-gauge steel body is heavier than standard 18-gauge, which translates to less flex, better sound resistance, and a more solid feel when loading the sink. The sink undermounts beneath the counter, so no rim or ledge sits above the surface to interrupt the worktop or collect debris along the edge.
This is a sink for a kitchen designed with a consistent finish language. If the faucet, pulls, and cabinet hardware run dark, a Gunmetal Grey sink carries that palette into the basin rather than breaking it with a standard bright stainless. It suits a primary kitchen remodel or new build where the counter is being fabricated to accept an undermount, and it works in spaces where the cook regularly uses both sides of a double bowl, such as a high-use family kitchen or a cooking-focused island setup. Because it is an undermount sink, it requires a countertop material that supports undermounting, such as quartz, granite, or solid surface, and the counter should be planned for this sink before the countertop is cut.
The Gunmetal Grey is a finished surface treatment on the stainless steel bowl. It gives the sink a distinctly darker tone compared to standard brushed stainless without a painted or coated look.
Undermount sinks like this one are typically installed beneath quartz, granite, or solid surface countertops. Confirm your countertop material supports undermounting before the cutout is made.
Yes. The sink is a 50/50 equal split. Both bowls measure 14-3/8 inches in interior length and 16-1/8 inches in interior width.
The sink ships without a grid or strainer. Compatible accessories are available separately. The drain opening in each bowl is 3-1/2 inches.
Choose the Karran Matrix in Gunmetal Grey for an undermount kitchen sink that anchors a dark-hardware design and handles the full load of a working kitchen across two equal bowls.
