Gray Quartz Undermount Sink for a Hardworking Kitchen Counter

This Karran quartz undermount kitchen sink delivers a 60/40 double-bowl layout in a warm gray finish, designed to mount beneath granite, quartz, or solid surface countertops and handle the full workload of a busy kitchen.

Key Features

• 60/40 double-bowl configuration gives a larger primary bowl for washing and a compact secondary bowl for rinsing or prep.
• Quartz composite construction blends natural quartz with acrylic resin for a dense, stone-weight body in gray.
• Undermount installation into granite, quartz, or solid surface countertops keeps the counter surface clean and uninterrupted.
• Requires a 36-inch minimum cabinet width for proper fit and installation.
• 3-1/2 inch waste opening on each bowl for standard drain and disposal hardware.
• cUPC and IAPMO certified for plumbing code compliance.

Two Bowls Sized for Real Kitchen Workflow

The 60/40 split means the two bowls are not equal partners. The larger left bowl handles full-size pots, sheet pans, and soaking dishes without crowding. The smaller right bowl stays free for rinsing produce, draining pasta, or holding a colander while the main bowl is in use. That division of labor keeps both sides useful throughout a meal rather than one bowl monopolizing the sink. For kitchens where the single-bowl approach leaves no room to multitask, the offset split is a practical improvement over an equal double-bowl layout.

Gray Quartz in a Countertop Context

Gray is a neutral that reads differently depending on what it sits beside. Against white or light-toned quartz countertops it adds contrast and definition. Against a gray or concrete-look countertop it blends into the surface for a monolithic appearance. The quartz composite body gives the sink heft and a matte, stone-like surface rather than the reflective quality of stainless steel, which means it holds its appearance without showing every water spot or minor scratch the way a polished surface would. Undermounting keeps the counter edge running straight to the bowl rim with no visible flange on top, reinforcing the seamless look regardless of countertop color.

Where This Sink Fits

This is a sink for a primary kitchen installation in a new build or a full remodel where the countertop is being fabricated. Because it undermounts, it is designed for hard countertop materials, specifically granite, quartz, and solid surface, and requires a new countertop rather than an existing cutout from a prior sink. The 32-inch by 21-1/4 inch footprint fits a 36-inch base cabinet. It suits homeowners who want gray in the sink to coordinate with or contrast against the countertop, designers specifying a gray palette, and remodelers replacing an older drop-in with a cleaner undermount profile. It is not ADA compliant, so for accessibility-required applications, a different specification is needed.
