The Karran QU-820 is a single-bowl quartz undermount kitchen sink finished in Concrete, a cool, muted gray tone that reads as raw and modern rather than stark. It mounts beneath quartz, solid surface, or granite countertops for a seamless edge-to-bowl transition.
A single, uninterrupted bowl gives you the full interior without a divider taking up space in the middle. The 9-inch depth is deep enough to submerge tall stockpots and large roasting pans, and the 22-inch interior length gives you room to rinse a baking sheet flat without tilting it. If most of your sink work is washing large cookware rather than running two tasks at once, this configuration stays out of your way.
The sink body is a quartz composite, an engineered material that uses quartz as its primary component. The Concrete finish gives the bowl a cool, slightly textured appearance that sits between polished stone and raw industrial surfaces. It pairs naturally with poured-concrete countertops, light gray quartz, exposed-aggregate surfaces, and matte black or brushed hardware. The consistent through-color means chips or scuffs, if they occur, do not expose a contrasting base layer beneath the surface.
This sink is the right call for a kitchen designed around industrial, transitional, or Scandinavian-influenced aesthetics where a white or black sink would feel too expected. Designers specifying a muted palette with gray quartz or concrete-look countertops will find the Concrete finish integrates without dominating the surface. It also works for a kitchen remodel or new build where the countertop is being fabricated fresh, since undermount sinks require the countertop to be built around them. The 27-inch minimum cabinet width means it fits a standard 30-inch base cabinet with room to spare, and its cUPC certification satisfies North American code requirements.
The matte, textured character of the Concrete finish is more forgiving of light wear and water residue than a polished or high-gloss surface. For specific care instructions, follow the manufacturer's guidance for quartz composite sinks.
It is designed to undermount into quartz, solid surface, and granite countertops. It is not intended for laminate, tile, or other countertop types that cannot fully support an undermount installation.
A minimum cabinet width of 27 inches is required. The sink's outer dimensions are 24-3/8 inches wide by 19-1/8 inches front to back.
This SKU is configured as 20 sinks nested per pallet, suited to contractors, designers, or distributors specifying the same sink across multiple units in a project or stocking multiple kitchens at once.
Choose the Karran QU-820 in Concrete when the design calls for a sink that brings a grounded, modern presence to the countertop without pulling focus away from the rest of the kitchen.
