The Karran QU-820 is a single bowl quartz composite undermount kitchen sink built for kitchens where counter space is at a premium. At 24-3/8 inches wide, it delivers a full 9-inch deep basin in a footprint that suits narrower sink base cabinets without sacrificing working depth.
• 80% quartz, 20% acrylic resin construction gives the bowl its scratch, stain, chip, and heat resistance in daily kitchen use.
• Single bowl configuration provides an uninterrupted 24-3/8 by 19-1/8 inch interior for washing large cookware without a divider in the way.
• 9-inch bowl depth keeps splashing contained and accommodates tall stock pots and baking sheets with ease.
• Flat mounting rim with no faucet deck means the faucet and any accessories mount through the countertop, keeping the sink profile clean beneath stone or solid surface.
• White finish coordinates with light countertops and cabinet interiors for a clean, unified look.
• Undermount installation leaves no exposed rim above the counter for a flush, wipe-clean transition from counter to bowl.
The QU-820 is the right call when a full-depth single bowl is needed but the cabinet run does not leave room for a 30-plus-inch sink. Secondary kitchens, butler's pantries, and smaller renovation layouts all benefit from its compact width without giving up the bowl volume that makes a single basin practical. It also works well in cottage and in-law suite builds where a single-bowl layout keeps plumbing simple and the cabinet count efficient. Because the faucet mounts through the countertop rather than through a sink deck, the finished look is especially clean on granite, engineered stone, and solid surface tops where a countertop drilling is standard practice anyway.
Karran's quartz composite formula — 80% natural quartz crystals bound in 20% high-performance acrylic resin — produces a bowl that resists the routine abuse of a working kitchen: knife drops, heavy pots set down hard, and the daily cycle of hot and cold water. The White finish runs through the material rather than sitting as a surface coating, so chips and nicks do not expose a contrasting substrate. The flat rim profile is engineered for standard undermount installation in quartz, granite, and solid surface countertops, with a small positive or negative reveal agreed with the fabricator before the cutout is made. No template or mounting clips are included; fabricators typically work from the actual sink or a downloaded DXF file.
Cabinet shops specifying a client's secondary kitchen or compact renovation reach for the QU-820 when the design calls for a single unbroken bowl in a restrained footprint. Designers working with a narrow island or a galley layout appreciate that the undermount profile keeps the counter surface continuous and easy to wipe down. Homeowners remodeling a smaller kitchen get a bowl deep enough to handle genuine cooking tasks without the installation complexity of a farmhouse or workstation sink. It is a straightforward, durable choice for any project where the priority is a clean countertop line and a functional, full-depth single bowl in White.
Through the countertop. The QU-820 has no faucet deck, so the faucet, soap dispenser, and any other accessories drill into the stone or solid surface top behind the bowl. Your fabricator handles those drillings as part of the countertop work.
Karran does not publish a minimum cabinet size on this model's spec sheet, but the 24-3/8 inch overall width typically suits a 27-inch or larger sink base cabinet. Verify with your fabricator against the actual cabinet opening and support ledge before finalizing the cutout.
No. Karran QU Series sinks do not include a paper template or mounting clips. Fabricators can use the actual sink as a guide or download a DXF file for CNC cutouts from Karran's resources.
The QU-820 is documented for standard undermount installation in quartz, granite, and solid surface countertops. Seamless laminate installation is specific to Karran's Q Series, not the QU Series. For a laminate top, the Q Series is the correct fit.
No. The drain and basket strainer are sold separately. Order a drain sized for the standard 3-1/2 inch kitchen bowl opening when you source the sink.
The QU-820 brings a deep, full-capacity single bowl into kitchens that cannot accommodate a wider sink, without trading away the material quality or clean undermount profile that make quartz composite a lasting choice.
