A Gray Quartz Undermount Sink Built for the Working Kitchen

This Karran 60/40 double-bowl sink is a quartz undermount kitchen sink finished in Gray, sized for a 36-inch base cabinet and designed to install beneath granite, quartz, or solid surface countertops.

Key Features

• 60/40 double-bowl configuration gives a larger primary basin and a smaller secondary bowl for task separation.
• Quartz composite construction with the heft and matte surface quality of stone.
• Gray finish that works with both cool and warm kitchen palettes.
• Undermount installation into granite, quartz, or solid surface countertops.
• cUPC and IAPMO certified for North American plumbing code compliance.
• 3-1/2 inch drain openings on both bowls, compatible with standard basket strainers and disposal flanges.

Two Bowls, One Practical Split

The 60/40 bowl split gives the larger left basin room to handle full-sized pots and sheet pans, while the right basin stays available for rinsing produce, soaking a cutting board, or keeping a filled colander out of the main workflow. That division is the reason a 60/40 sink suits a kitchen where serious cooking and cleanup happen at the same time. Because it mounts under the counter, the countertop surface runs directly to the bowl edges with no rim or seam above the waterline to trap debris or complicate wiping down.

Quartz Composite in Gray

The sink body is quartz composite, a dense engineered material that has the weight and matte surface of stone without the porosity. The Gray finish reads as a true neutral, pulling toward cool without committing hard to either a warm or cool palette, which makes it a reliable pairing for white, cream, charcoal, and greige cabinet finishes alike. The matte surface handles the visual demands of a working kitchen better than polished alternatives, and the composite body resists the dings and marks that accumulate in a frequently used basin.

Where This Sink Fits

Plan this sink into a kitchen remodel or new build where the countertop is granite, quartz, or solid surface and a 36-inch base cabinet is in the layout. The 33-1/2 by 20-5/8 inch footprint is sized for that standard base width, and at 9 inches deep on both sides it handles volume cooking without being so deep that it becomes awkward to use. It is a strong fit for a main kitchen where the cook wants task-separated bowls, for a designer specifying a neutral sink that holds its ground across multiple countertop and cabinet finish combinations, or for a cabinet shop pre-selecting a sink that will pair cleanly with a quartz countertop package. ADA compliance is not listed for this model, so it is not the choice for an accessibility-driven design.

Common Questions

A Neutral Sink That Anchors the Kitchen Without Competing With It

Choose this Gray quartz sink when the countertop is solid stone or engineered quartz, the cabinet layout includes a 36-inch base, and the design calls for a sink finish that adapts to the room rather than dictating it.
