A Gray Quartz Apron-Front Sink for the Modern Farmhouse Kitchen

The Karran QA-740-GR is a single-bowl apron-front farmhouse sink in a Gray quartz composite finish, designed to undermount into granite, quartz, or solid surface countertops in kitchens where a neutral, contemporary palette sets the tone.

Key Features

• Apron-front farmhouse profile with the front panel exposed at the cabinet face for a classic, built-in look.
• Single bowl design with 31 inches of interior length and 9 inches of bowl depth for a generous work basin.
• Gray quartz composite construction blending natural quartz with acrylic resin throughout.
• Undermount installation into granite, quartz, or solid surface countertops, with a minimum 36-inch cabinet width required.
• 3-1/2 inch drain opening compatible with standard basket strainer fittings.
• cUPC and IAPMO certified for plumbing compliance in residential and commercial applications.

One Deep Basin, Front and Center

An apron-front sink makes its front panel part of the kitchen's visual composition rather than tucking it behind the countertop edge. That exposed apron is the defining feature of the farmhouse look, and the single bowl format gives a continuous, uninterrupted workspace suited to large pots, sheet pans, and busy prep sessions. Gray sits between the extremes of black and white, making it a practical match for countertops in concrete tones, warm whites, or veined quartz where a neutral basin blends without disappearing.

Gray Quartz Composite, Through and Through

The sink body is built from natural quartz blended with acrylic resin, a dense composite material with color that runs throughout rather than sitting on a surface coating. The Gray finish holds its tone even as the sink wears in, and the quartz composite surface resists staining and keeps food residue from bonding to the bowl. The material is non-porous, so it does not harbor bacteria the way a porous surface can. Because this is a quartz composite, not a ceramic or vitreous material, it takes a different installation path than a fireclay or cast-iron farmhouse sink.

Planning the Installation

This sink is undermount only and is designed for new countertop fabrication. It is not intended to drop into an existing cutout from a previous sink, so it belongs in a remodel or new build where the countertop is being fabricated to fit. The 34-inch overall width requires a minimum 36-inch base cabinet. It is designed to undermount into granite, quartz, and solid surface countertops. Confirm the base cabinet is built for a farmhouse apron-front sink before ordering, since an apron-front profile requires a cabinet with a recessed or modified face to accept the exposed front panel.
