Karran Quartz Undermount Kitchen Sink for Transitional and Modern Kitchens in Gray

This Karran single-bowl undermount kitchen sink is built from quartz composite and finished in Gray, a neutral mid-tone that pairs naturally with white, charcoal, wood-tone, and concrete-look countertops. It mounts beneath the counter surface for a clean, uninterrupted look and is sized for a 36-inch base cabinet.

Key Features

• Single-bowl quartz composite construction in a Gray finish that coordinates with a wide range of kitchen palettes.
• Undermount installation compatible with granite, quartz, and solid surface countertops.
• 33-1/2 inch overall width with an inside bowl measuring 31 inches long by 18-1/2 inches wide and 9 inches deep.
• Minimum 36-inch base cabinet required for proper fit.
• 3-1/2 inch drain opening for standard drain and disposal connections.
• cUPC and IAPMO certified for plumbing code compliance.

One Basin, Unobstructed

A single bowl this size handles full sheet pans, large stock pots, and oversize cutting boards that two-basin sinks can't accommodate without splitting the load. The 9-inch bowl depth keeps splashing contained during heavy rinsing, and the undermount profile means there's no rim ledge collecting debris at the counter edge. For kitchens built around batch cooking, entertaining, or serious prep work, an open single bowl keeps the workflow moving without dividing the space.

Gray Quartz Composite: The Material Behind the Finish

Quartz composite sinks are dense and heavy by nature, and this one carries the Gray colorway through the full body of the material rather than as a surface coat. Gray reads differently under different lighting conditions: warmer cabinet pulls and brass hardware tend to shift it toward taupe, while chrome and matte black hardware keep it in a cooler, more industrial register. The quartz composite surface is non-porous, which means it doesn't absorb food residue, and the material holds up to the temperature swings that come with daily cooking use.

Where This Sink Fits

This sink is the right call for a kitchen remodel or new build where the countertop is being fabricated from scratch in granite, quartz, or solid surface. Because it is undermount only, it is designed for new countertop installations and is not suited to dropping into an existing cutout. Designers specifying gray as the through-line in a transitional or Scandinavian-influenced kitchen will find this a straightforward coordinate. Cabinet shops building frameless kitchens with 36-inch sink bases can plan the cutout directly from the 33-1/2 by 21-inch footprint. Contractors sourcing for a full kitchen renovation have the cUPC and IAPMO certifications on hand for inspection.
