Gray Quartz Tone And A Single Deep Bowl Built For 36-Inch Cabinets

The Karran QU-712-GR is a single-bowl quartz undermount kitchen sink in Gray, sized to fit a 36-inch base cabinet and designed to mount beneath granite, quartz, or solid surface countertops.

Key Features

• Gray quartz composite body that holds color through the material, not just at the surface.
• Single deep bowl with a 9-inch inside depth for large pots, sheet pans, and oversized cookware.
• Undermount installation into granite, quartz, or solid surface countertops only.
• Requires a 36-inch minimum cabinet width for proper fit and clearance.
• cUPC and IAPMO certified for residential plumbing compliance.
• 3-1/2-inch drain opening for standard kitchen strainers and disposal flanges.

What the Single Bowl Is Built For

One uninterrupted basin handles jobs that a divided sink cannot. A 30-inch interior bowl length accommodates a full hotel pan, a large stockpot, or a sheet tray without the divider getting in the way. The 9-inch depth keeps water and splatter contained even when the sink is loaded. For a kitchen where serious cooking means serious cleanup, a single bowl of this size is the right tool.

Gray Quartz Composite In The Kitchen

Gray reads as a neutral without being a non-choice. It coordinates cleanly with white, black, and wood-tone cabinetry, and it sits well under both light and dark countertop materials. The quartz composite construction means the gray color runs through the body of the sink rather than sitting as a surface coat, so chips and scratches at the rim or bowl edge stay consistent with the rest of the surface. The undermount profile removes the exposed rim from the countertop plane, which lets the stone or quartz surface run right to the bowl edge and makes wiping the counter directly into the sink straightforward.

Where This Sink Fits Best

This sink is the right call for a new kitchen build or a countertop replacement where the base cabinet is already 36 inches wide and the countertop is granite, quartz, or solid surface. It is an undermount, so it needs a countertop fabricated to accept it and cannot drop into an existing laminate countertop cutout. Designers specifying a neutral palette find gray quartz easy to carry across multiple finishes in the same space. Cabinet shops and contractors building new kitchens can plan it as a standard single-bowl undermount that meets cUPC and IAPMO plumbing certification requirements without additional documentation.
