A 32-Inch Undermount Sink Built for Two-Station Kitchen Work
The Karran QU-711 is a large/small bowl quartz composite kitchen sink that undermounts beneath stone, quartz, and solid surface countertops. Its offset bowl layout pairs a deep primary wash basin with a smaller prep bowl, letting a single sink handle two tasks at once without interrupting the countertop's clean, seamless look.
Key Features
• 80% quartz / 20% acrylic resin construction delivers a scratch-, stain-, chip-, and heat-resistant bowl that holds up to daily kitchen use.
• Undermount installation positions the sink beneath the counter, leaving no exposed rim and making the countertop easy to wipe clean.
• Large/small offset bowl configuration dedicates most of the interior to the primary wash station while keeping a shallower prep bowl within reach.
• 9-inch bowl depth on both basins accommodates stock pots, large mixing bowls, and baking sheets comfortably.
• Matte Black finish integrates with dark or contrast hardware schemes and resists showing water spots and residue between cleanings.
• No faucet deck means the faucet and any accessories mount through the countertop, keeping the sink profile uncluttered.
Where the Offset Layout Earns Its Place
An equal double bowl splits the cabinet evenly and works well when two people are at the sink at the same time. The large/small layout takes a different approach: the larger bowl handles everything that needs full submersion or heavy scrubbing, and the smaller bowl is always available for draining a colander, soaking a cutting board, or running cold water while the main bowl is full. For households that cook frequently, that separation removes a constant source of conflict at the sink. In a kitchen with a disposal, the smaller bowl is often the right side to drop it into, keeping the larger basin unobstructed. Cabinet shops and designers specifying for clients who entertain or cook daily will find the asymmetric layout addresses real workflow friction the moment it is installed.
Quartz Composite in Matte Black
The QU-711's bowl is formed from quartz composite, a material that handles the heat, impact, and abrasion that a kitchen sink takes every day. Unlike a coated or painted surface, the Black finish runs through the material, so edge nicks and minor abrasions do not expose a contrasting layer underneath. The matte surface texture sits between gloss and rough: it does not show fingerprints or water deposits the way polished finishes do, and it cleans with a soft cloth and standard household cleaners. The composite material does not require sealing and will not corrode or rust. For designers pairing the sink with dark faucet finishes such as Matte Black or Gunmetal Grey, the bowl reads as a true, dense black rather than a surface coating.
Right for These Kitchens and Installers
The QU-711 fits a 36-inch sink base cabinet and suits new construction and full kitchen remodels where the countertop is being fabricated fresh. Because it undermounts, the countertop material needs to be stone, engineered quartz, or solid surface with a finished edge — this is not the sink for a laminate counter where the cutout edge cannot be exposed. Homeowners renovating with a quartz or granite top and looking for a bold contrast piece will find the Matte Black practical as well as visual. Contractors and cabinet shops pricing out kitchens where the client wants a departure from stainless should put this on their short list for a hardworking, low-maintenance alternative.
Does the faucet mount on the sink or on the countertop?
On the countertop. The QU-711 has no faucet deck, so all faucet holes and accessory drillings go through the counter material behind the sink. That keeps the sink itself clean-lined but does require the countertop to be drilled during fabrication.
Which bowl is larger — left or right?
The SAP description references a left-side large bowl and right-side small bowl orientation. Confirm the handed orientation from the product documentation or contact us before specifying, as bowl orientation can affect the disposal location and plumbing layout.
Does this sink come with a drain, grid, or template?
The QU-711 is a bare sink. Drains, grids, mounting clips, and a paper template are not included and must be purchased separately. Karran publishes DXF cutout files for CNC shops that prefer them over a paper template.
Is quartz composite the same as granite composite?
Not exactly. Karran's quartz composite is 80% natural quartz crystals bound in 20% acrylic resin. Some competing sinks use granite particles in a similar resin system. The materials look and perform comparably, but this sink is quartz composite — not granite composite, stone, or solid quartz.
Can this sink go into a laminate countertop?
No. The QU series is designed for undermounting in stone, engineered quartz, or solid surface countertops where the cutout edge can be finished and left exposed. For a seamless laminate installation, Karran's Q Series is the right choice.
One Sink, Two Tasks, Zero Compromises on the Counter
The QU-711 brings a professional-grade quartz bowl to kitchens where the counter look matters as much as the workflow, delivering an offset layout that handles prep and cleanup simultaneously without a rim breaking up the countertop surface.
