Karran Quartz Undermount Sink for a Gray Kitchen Build

This Karran quartz kitchen sink is a 60/40 double-bowl undermount designed for granite, quartz, and solid surface countertops, finished in gray.

Key Features

• 60/40 double-bowl configuration gives a larger primary basin and a smaller secondary bowl for added workflow flexibility.
• Quartz composite construction for a dense, stone-like body with consistent color throughout.
• Undermount installation into granite, quartz, or solid surface countertops.
• Gray finish that pairs naturally with cool-toned countertops, cabinetry, and appliances.
• Minimum 36-inch cabinet width required to accommodate the 32-inch overall footprint.
• IAPMO certified for plumbing code compliance.

Two Bowls, One Practical Split

The 60/40 split sets this sink apart from an equal double-bowl. The larger left bowl handles pots, sheet pans, and deep soaking jobs where a half-sized basin would feel cramped. The smaller right bowl stays free for rinsing produce, draining a colander, or keeping a dish-soap setup out of the main workspace. It is the configuration that suits an active cooking kitchen where one large basin alone would still leave you wishing for a second one.

Quartz Composite in Gray

The sink body is quartz composite, a dense material that reads as stone without the maintenance demands of natural stone. The gray finish sits in a neutral mid-tone range that works well alongside white, charcoal, or warm-wood cabinetry and holds its own under stainless appliances and cool-toned stone countertops. Because the undermount installation conceals the sink rim below the counter surface, the gray color becomes the visual detail rather than a rim edge, making finish selection more consequential than it would be with a drop-in.

Where This Sink Fits

This is the right sink for a main kitchen build or a full kitchen remodel where the counter is being fabricated new. Undermount installation requires a countertop that supports it, specifically granite, quartz, or solid surface. The sink needs a cabinet of at least 36 inches wide to seat the 32-inch body with room for a proper cutout. It is not a drop-in replacement for an existing countertop with a cutout already in it. Plan it into a new countertop, and confirm the cabinet width and the 19-1/2 inch front-to-back depth against your layout before ordering. The IAPMO certification means it satisfies standard plumbing code requirements for residential installs.
