A Deep Single Bowl Sink Built for Heavy Kitchen Work
The Karran QU-812 is a large single bowl quartz composite undermount sink designed for kitchens where washing volume and uninterrupted bowl space matter most. At 32-1/4 by 19-1/4 inches overall with a 9-inch deep bowl, it mounts beneath quartz, granite, and solid surface countertops and delivers the workhorse capacity a busy kitchen demands — all in a bold Black finish.
Key Features
• Extra-large single bowl provides an uninterrupted workspace that accommodates full sheet pans and large cookware without a center divider in the way.
• 80% natural quartz and 20% acrylic resin construction delivers high resistance to scratches, stains, chips, and heat across the full bowl surface.
• Flat undermount rim allows installation beneath the countertop for a clean, wipe-down counter edge with no visible rim protruding above the surface.
• Black quartz finish resists showing water spots and daily residue while making a strong visual statement against light countertops.
• No faucet deck keeps the countertop plane uninterrupted — the faucet and any accessories mount through the countertop behind the bowl.
What This Sink Is Made For
A 9-inch deep bowl with no center divider is the right tool for kitchens that move volume: batch cooking, canning runs, washing large stockpots, or managing heavy prep without constantly shuffling items around a divider. The full interior is yours to work with. There is no split to compromise on one side or the other, and the depth keeps water from splashing out during aggressive rinsing. Undermount placement keeps the counter edge fully exposed for wiping food debris directly into the bowl — a practical advantage for any cook who values a clean prep surface.
Material and Finish
Quartz composite sinks take the hardest part of the kitchen and give it a material that can match that pace. The 80% quartz and 20% acrylic resin blend is highly scratch, stain, chip, and heat resistant — properties that matter in a single bowl that handles everything from cast iron to acidic prep. The Black color runs through the full composite body, so minor surface contact does not expose a contrasting layer underneath. Because the QU-812 is a quartz undermount model and not a Q Series seamless sink, it installs in the conventional way beneath quartz, granite, and solid surface countertops. Faucet and soap dispenser holes are drilled through the countertop, keeping the bowl itself clean-lined. The drain assembly is sold separately — size and drain configuration should be confirmed before purchase.
Who Should Specify This Sink
Cabinet shops and countertop fabricators specifying for high-use residential kitchens will find the QU-812 a natural fit for clients who cook seriously and want a sink that does not compromise on space or durability. Designers working with dark quartz or stone countertops will appreciate how the Black bowl integrates rather than contrasts. Homeowners replacing a divided sink often choose this configuration once they experience what the full floor area of a single bowl provides. The undermount installation suits any fabricator already routing or cutting countertop openings, and the absence of a faucet deck makes the countertop layout fully flexible.
Frequently Asked Questions
Does this sink install seamlessly in laminate countertops?
No. The QU-812 is a quartz undermount sink in the QU series, which installs conventionally beneath quartz, granite, and solid surface countertops. Seamless laminate installation is specific to Karran's Q Series. This sink's flat rim sits against the underside of the countertop and is secured with the appropriate undermount clips and fasteners for the countertop material.
Is the drain assembly included?
No. A drain or basket strainer is not included with the QU-812 and must be sourced separately. Confirm the drain configuration before purchase.
Where does the faucet mount on this sink?
The QU-812 has no faucet deck. The faucet, soap dispenser, and any other accessories mount through holes drilled in the countertop behind the bowl. This gives the installer and designer full flexibility over hole placement and count.
Can large pots and sheet pans lie flat in this bowl?
The single bowl's uninterrupted interior is designed for exactly that. Without a center divider, the full floor of the bowl is available, and the 9-inch depth provides room to soak or fill tall items without the bowl overflowing at low water levels.
The Right Bowl for Kitchens That Work Hard
For a kitchen built around serious cooking and daily heavy use, the QU-812 delivers the bowl space, depth, and material durability to match. Its Black quartz composite finish holds up to the work and looks sharp doing it.
