Gray Quartz Undermount Sink for a Modern Kitchen Countertop

This Karran 60/40 double-bowl undermount sink is a quartz-composite kitchen sink in gray, designed to mount beneath granite, quartz, or solid surface countertops in a 36-inch or wider base cabinet.

Key Features

• 60/40 double-bowl configuration with a larger left basin and a smaller right basin sized for two-zone kitchen workflows.
• Undermount installation into granite, quartz, or solid surface countertops.
• Quartz composite construction in a gray finish for a clean, neutral kitchen aesthetic.
• cUPC and IAPMO certified for compliance with North American plumbing standards.
• 3-1/2 inch drain opening in each bowl, sized for standard kitchen strainers and disposal flanges.
• Requires a 36-inch minimum cabinet width for proper fit and installation clearance.

Two Zones, One Sink

A 60/40 split gives you two bowls with different sizes rather than two equal halves. The larger left basin handles the bulk work: soaking a stock pot, washing oversized baking sheets, or submerging a colander of produce. The smaller right basin stays free for rinsing, draining, or keeping a second task moving while the main bowl is occupied. Gray is a finish that reads as neutral without disappearing into the background, sitting naturally alongside both cool-toned and warm-toned countertops without competing with the cabinetry.

Quartz Composite Built for Kitchen Duty

The sink body is a quartz composite material, a dense engineered blend that gives the sink the solidity and heft of stone. Gray finishes on quartz composite are forgiving on minor marks and water spotting compared to lighter colors, which suits a sink that sees daily use. Each bowl measures 9 inches deep, so there is meaningful basin depth to work with, whether that means a full stock pot or a tall pitcher fitting under the faucet without being tipped on its side.

Where This Sink Fits

This sink is the right choice for a kitchen remodel or new build where the countertop is granite, quartz, or solid surface and the base cabinet is 36 inches wide or wider. Because it is an undermount sink, it needs to be planned into a new countertop fabrication rather than dropped into an existing cutout. Undermounting keeps the counter surface running cleanly to the bowl edge with no rim to catch debris, which makes cleanup faster on a busy kitchen counter. The gray finish is a practical pick for designers specifying a cohesive, neutral palette, and for homeowners who want a sink that holds its look over years of use without showing every water mark.
