Equal Bowls, Zero Compromise, and a Finish That Holds Its Ground
The Karran QU-810 is a quartz composite undermount kitchen sink with two equal-sized bowls, sized at 32 by 19-1/2 by 9 inches and finished in Black. It mounts beneath the countertop with a clean, rimless profile and arrives as a ready-to-install kit that includes stainless steel basket strainers, bottom grids, and Luster Pro oil.
Key Features
• 80% quartz, 20% acrylic resin construction delivers a surface that stands up to scratches, stains, chips, and heat in daily kitchen use.
• Double equal bowl configuration splits the interior into two matched basins, supporting a dedicated wash-and-rinse or wash-and-prep workflow.
• Undermount installation positions the sink below the countertop so crumbs and spills wipe directly into the basin without a rim to stop them.
• 9-inch bowl depth handles tall pots and full colanders without crowding the workspace above.
• Kit includes stainless steel basket strainers, bottom grids, and Luster Pro oil so the sink is ready to drop in without sourcing accessories separately.
• Matte Black finish provides a bold, low-maintenance surface that resists water spots and coordinates with matte and black hardware across the kitchen.
Where the Equal-Bowl Layout Earns Its Keep
A 50/50 bowl split suits kitchens where two tasks routinely run at the same time. One side soaks a stockpot while the other stays clear for rinsing vegetables. One side collects dishes while the other handles a quick hand wash. With 9 inches of depth in each basin, neither side feels cramped, and the equal sizing means neither person working the sink is working the short end. This is a practical layout for busy households, kitchen renovations where the daily volume is high, and any project where the client wants to skip the decision of which bowl gets the larger footprint.
Quartz Composite in Black: What the Material Delivers
Quartz composite sinks in Black are a specific material choice, not just a color preference. The Black finish here is integral to the quartz and acrylic resin body rather than a surface coating, which means chips that reach the surface do not expose a lighter substrate underneath. The material is documented by the manufacturer as highly scratch, stain, chip, and heat resistant, making it durable enough for the daily abuse of a primary wash station. The matte surface of the Black finish also tends to hide water spots and light residue that would be visible on a high-gloss or polished sink. The bottom grids included in the kit protect the basin floor while keeping cookware off the surface.
Who Specifies This Sink and Why
Cabinet shops building kitchens around quartz, granite, or solid surface countertops will find the QU-810 straightforward to specify: it undermounts beneath any of those materials using standard undermount methods, with the faucet drilled through the countertop rather than through a sink deck. Designers working with clients who have chosen matte black fixtures and hardware across the kitchen can treat this sink as the anchor piece that ties the finish story together. Homeowners remodeling a primary kitchen who want the visual weight and durability of a black quartz sink without ordering grids and strainers separately will get everything in one shipment.
Does the QU-810 work with granite and engineered quartz countertops?
Yes. The QU undermount series installs beneath quartz, granite, and solid surface countertops using standard undermount clips and methods. The faucet mounts through the countertop, since the sink has no faucet deck of its own.
Is a paper template or DXF file included for the countertop cutout?
No. Karran's QU Series spec sheets state that no template or clips are included with the sink itself. The kit contents are the basket strainers, bottom grids, and Luster Pro oil. Confirm the cutout dimensions from the spec sheet before fabrication, and have the actual sink on hand before making the cut.
Will either bowl accept a garbage disposal flange?
Disposal compatibility depends on the drain flange used and the installation setup. The sink's drain openings accept standard 3-1/2 inch kitchen strainers and compatible disposal flanges, but confirm the specific flange model fits before installation.
How do I care for a black quartz composite sink?
Routine cleaning with a non-abrasive cleaner and a soft cloth is all the surface needs. The Luster Pro oil included in the kit conditions the material and helps maintain the finish. Avoid harsh abrasive pads, which can dull the matte surface over time.
A Sink That Shows Up Ready to Work
The QU-810 Black kit bundles the sink with the accessories most installers would need to source anyway, so the project moves to install day without a separate accessories order standing in the way.
