A Gray Quartz Undermount Sink Built for Asymmetric Bowl Work

This Karran quartz undermount kitchen sink pairs a larger and a smaller bowl in a 60/40 split, finished in Gray, and installs beneath granite, quartz, or solid surface countertops for a clean, rimless look at the counter surface.

Key Features

• 60/40 unequal double bowl with a deeper large side for soaking and a compact second bowl for rinsing or prep.
• Gray quartz composite material for a neutral, contemporary tone that pairs with a wide range of countertop finishes.
• Undermount installation designed for granite, quartz, and solid surface countertops.
• 3-1/2 inch drain openings in both bowls, sized for standard basket strainers or disposal flanges.
• cUPC and IAPMO certified to meet plumbing code requirements.
• Requires a minimum 36-inch base cabinet to fit the 32-inch overall length.

How the 60/40 Layout Works for You

The 60/40 split gives the large bowl a 17-1/8 inch length and a 9-inch depth for soaking pots and stacking dishes, while the smaller bowl at 11-1/2 inches handles rinsing produce, filling a pitcher, or keeping a colander in place without crowding the main basin. For anyone who spends real time at the sink, this division of labor keeps both sides useful rather than forcing everything into equal halves that are almost big enough for either task but perfect for neither.

Gray Quartz Composite and What It Means for the Kitchen

Gray sits between the warm and cool ends of the neutral palette, making it one of the more versatile sink colors for kitchens that want something more interesting than white but less committed than black. The quartz composite material carries that tone consistently through the body, so chips and wear do not expose a different color underneath. As an undermount, the sink mounts below the counter surface with no visible rim, which keeps wipe-down from counter to bowl direct and unobstructed.

Where This Sink Belongs

This is a primary kitchen sink for a 36-inch or wider base cabinet in a new build or full kitchen remodel, where the countertop is being fabricated new. Because it is undermount only, it cannot drop into an existing cutout sized for a top-mount or drop-in rim. It suits designers and cabinet shops specifying for a contemporary kitchen that calls for a gray-toned, rimless basin, and remodelers building a stone or solid surface counter who want the two-basin flexibility of a 60/40 layout without going to a full equal double bowl. The cUPC and IAPMO certifications mean it meets the plumbing code requirements most jurisdictions require for permitted work.
