A Gray Quartz Undermount Sink For a Modern Kitchen Build

This Karran single-bowl quartz sink undermounts into granite, quartz, or solid surface countertops and brings a Gray finish that works naturally with a wide range of contemporary and transitional kitchen palettes.

Key Features

• Gray quartz composite construction with a consistent color and matte surface throughout the bowl.
• Single bowl undermount design that keeps the counter surface unbroken above the rim.
• 9-inch inside bowl depth for comfortable washing of large pots and sheet pans.
• Designed for granite, quartz, and solid surface countertops only.
• Requires a 36-inch minimum cabinet width for proper fit.
• cUPC certified, meeting North American plumbing standards.

One Deep Bowl, No Rim in the Way

A single-bowl configuration gives the full interior to one task at a time, whether that is soaking a large roasting pan, rinsing produce, or bathing a pet. Because the sink mounts beneath the countertop, the stone or solid surface runs cleanly to the bowl edge with no exposed lip to collect debris. The inside bowl measures 30 inches long by 16-3/4 inches wide and 9 inches deep, making it one of the more generous single-bowl footprints available in this format. The 3-1/2 inch drain opening accepts standard kitchen strainer hardware.

Gray Quartz That Holds Its Look

The sink is made from quartz composite, an engineered material that gives the bowl the density and weight of stone with a matte, color-through finish. Gray sits in the middle of the neutral range, cool enough to complement dark countertops and cabinet finishes without competing with them, and light enough to pair with white or light-gray stone. The matte surface keeps the bowl from looking wet between uses and reduces the visibility of water spots that stand out on a polished surface.

Where This Sink Fits the Project

This is a sink for a new kitchen build or a full remodel where the countertop is being fabricated from scratch. It is an undermount-only sink and must go into a new countertop surface, not an existing cutout. Granite, quartz, and solid surface are the confirmed compatible countertop materials. The sink needs a 36-inch base cabinet at minimum, so confirm the cabinet width before specifying it. It is a strong fit for designers building a neutral, modern kitchen where a cool-gray basin reads as part of the countertop rather than a separate fixture. It is equally practical for a cabinet shop pre-specifying plumbing hardware to a homeowner or contractor, since the cUPC certification satisfies North American rough-in inspections.
