A Gray Quartz Undermount Sink for a Working Kitchen

This Karran quartz kitchen sink is a 60/40 double-bowl undermount in Gray, sized to fit a 36-inch base cabinet and designed to mount beneath granite, quartz, or solid surface countertops.

Key Features

• 60/40 double-bowl layout gives a larger main basin for everyday washing and a smaller secondary bowl for prep or soaking.
• Quartz composite material with a consistent gray color throughout the body.
• Undermount installation into granite, quartz, or solid surface countertops.
• Requires a 36-inch minimum cabinet width to fit the 32 by 21 inch footprint.
• 3-1/2 inch drain opening in each bowl.
• cUPC and IAPMO certified for plumbing compliance.

Two Bowls, One Practical Split

A 60/40 split puts a deeper, wider main bowl on the left for pots, pans, and dish volume, and a narrower right bowl alongside it for rinsing vegetables, defrosting, or keeping one side clear while the other is in use. It is the configuration that suits a kitchen where the sink is doing real daily work, not just occasional light use. Both bowls share the same 9-inch depth, so neither side feels cramped when a deep stockpot is involved.

Gray Quartz That Holds Up in Use

The sink is made from quartz composite, an engineered material that carries its color through the full body rather than as a surface coating. The Gray finish reads as a cool mid-tone that coordinates naturally with white, concrete, or dark cabinetry without demanding an exact color match. Quartz composite is dense and non-porous, which means the surface resists staining and food residue does not grip the way it would on a softer material. Because the sink installs under the counter, there is no exposed rim to trap water or grime at the bowl edge.

Where This Sink Fits

This is a sink for a primary kitchen installation where the countertop is being fabricated new. It requires a countertop that supports undermounting, specifically granite, quartz, or solid surface, and it is designed for new construction or a full counter replacement rather than a drop-in swap into an existing cutout. Designers specifying a gray-toned kitchen will find the finish versatile across a wide range of cabinet colors. Cabinet shops and contractors setting up a full kitchen build can confirm fit against the 32-inch width and the 36-inch minimum cabinet requirement before the counter goes in. The sink is cUPC and IAPMO certified, which satisfies plumbing code requirements in most North American jurisdictions.
