Karran Quartz Undermount Sink For a Two-Station Kitchen Workflow
The Karran QU-810 is a double equal bowl quartz composite undermount kitchen sink that mounts beneath the countertop for a clean, wipe-across surface. The equal-bowl layout gives you a full-size wash station on each side, making it a strong match for kitchens that hand-wash dishes, need a dedicated rinse side, or like to keep prep and cleanup separate.
Key Features
• Quartz composite construction blends 80% natural quartz crystals with 20% acrylic resin for a highly scratch, stain, chip, and heat resistant bowl surface.
• Equal double-bowl layout divides the sink into two full-size basins, supporting wash-and-rinse or prep-and-cleanup workflows side by side.
• Undermount installation positions the sink beneath the countertop so no rim sits above the surface, allowing countertop debris to sweep directly into the bowl.
• White finish is a uniform color carried throughout the quartz composite, so minor surface wear does not expose a different color underneath.
• Kit includes stainless steel basket strainers, bottom grids, and Luster Pro oil so the sink is ready to install and protect from the start.
Where This Sink Fits the Work
A 50/50 bowl layout suits kitchens where two tasks regularly happen at the same time. One side holds soapy water while the other handles rinsing; or one bowl stays clear for meal prep while the other collects used cookware. The 9-inch bowl depth handles a standard stockpot without the rim interfering. This sink works in new kitchen builds and full counter replacements where the countertop is being cut to size — the faucet mounts through the countertop behind the sink, not through a deck on the sink itself, so the faucet position is flexible.
Countertop compatibility includes quartz, granite, and solid surface. This is a conventional undermount installation, not the seamless series, so the countertop edge is finished and visible above the sink rim.
Construction and Finish
Quartz composite combines the hardness of natural quartz with the workability of acrylic resin. The result resists the daily abrasions of pots, utensils, and cast iron that wear down softer materials over time, and it handles hot pans with the manufacturer's rated heat resistance. White is one of the most common sink colors specified alongside light-toned countertops and white cabinetry — and because the color is part of the composite material itself rather than a surface coating, the appearance holds through years of use. The finish does not require the periodic re-sealing that some stone sinks do.
Who Orders This Sink
Cabinet shops and kitchen remodelers building out a full countertop replacement will find the undermount format straightforward: set the countertop, mark the template, cut, and mount from below. Homeowners redoing a kitchen who want two equally sized bowls without an exposed rim above the counter reach for this model. Designers specifying a bright, neutral sink for a white or light quartz kitchen will appreciate that the White quartz composite reads consistently across lighting conditions and does not shift toward gray or cream.
Frequently Asked Questions
Does this sink include a drain or faucet?
The kit includes stainless steel basket strainers, bottom grids, and Luster Pro oil. A faucet and drain assembly are not included and are purchased separately. Because this is an undermount sink with no faucet deck, the faucet mounts through the countertop.
What countertop materials work with the QU-810?
This sink is designed for undermount installation in quartz, granite, and solid surface countertops. It is a standard undermount, not a seamless-series model, so it is not intended for laminate countertops.
Is a template included for the countertop cutout?
No. Per Karran's documentation for the QU series, a template is not included. A DXF file is available from Karran for shops doing CNC cutouts. Have the actual sink on hand before making the cut.
How does quartz composite compare to stainless steel for everyday kitchen use?
Quartz composite is quieter under running water and does not show water spots the way stainless can. It is highly resistant to scratches, stains, chips, and heat. Stainless offers its own advantages in gauge and finish variety — the right choice depends on your countertop material, cabinetry finish, and workflow.
What is the minimum cabinet size for this sink?
The QU-810 measures 32 inches by 19-1/2 inches overall. Confirm your sink base cabinet dimensions against the actual sink before cutting — cabinet requirements should be verified with the Karran spec sheet for this model.
