A Deep Single-Bowl Undermount Sink for Industrial-Inspired Kitchens

This Karran quartz undermount sink brings a concrete-finish, single-bowl basin to kitchens where a muted, industrial palette is the design goal. It mounts beneath quartz, granite, or solid surface countertops and is sized for a 36-inch base cabinet.

Key Features

• Concrete color quartz composite that reads as raw and understated rather than bright or polished.
• Single bowl, 9 inches deep for stacking pots, soaking large cookware, or handling bulky prep work without splitting space across two basins.
• Undermount installation into quartz, granite, or solid surface countertops only.
• Requires a minimum 36-inch base cabinet to accommodate the 31-3/4 inch overall width.
• cUPC and IAPMO certified for code compliance in residential and commercial applications.
• 3-1/2 inch drain opening compatible with standard kitchen strainers and disposal flanges.

One Basin, Full Depth

A single-bowl layout gives you one unbroken workspace instead of two divided ones. The 9-inch bowl depth handles a full stockpot without the rim catching on the faucet, and the 29-inch interior length leaves room to scrub sheet pans flat. For kitchens that cook seriously rather than just rinse and stack, a deep single bowl is frequently more practical than an equal-split double.

The Concrete Finish and What It Does in a Kitchen

Concrete as a finish color sits in a neutral, slightly warm gray register that reads closer to raw cast material than to a cool blue-gray. In a quartz composite sink, that tone is consistent through the material rather than a surface coating, so chips and wear do not expose a different color underneath. The finish pairs naturally with matte black or brushed brass fixtures, open-shelf cabinetry, and countertop materials that lean toward stone, wood, or concrete themselves. It is a quieter choice than black but carries more visual weight than white or bisque.

Where This Sink Fits Best

This is the right sink for a kitchen remodel or new build where the countertop is being fabricated new. Because it is an undermount, it cannot drop into an existing cutout from a previous sink installation. It suits a solid surface, quartz, or granite countertop where the fabricator can cut to the bowl dimensions and create a clean undermount reveal. Designers specifying an industrial or transitional kitchen will find the concrete finish useful as a grounding element when the surrounding materials are lighter or more varied. Cabinet shops building custom kitchens around 36-inch base cabinets can specify it without additional width modification.
