An Extra-Large Single Basin For Uninterrupted Kitchen Work
The Karran QU-712 is a 32-1/2 by 19-1/2 inch quartz composite undermount sink in White, built around one deep, uninterrupted 9-inch basin. Without a divider to cut the workspace, it handles oversized stock pots, full sheet pans, and large cutting boards that a divided bowl simply cannot accommodate.
Key Features
• Extra-large single bowl delivers an unobstructed 32-1/2 by 19-1/2 inch basin with a 9-inch depth for pots, pans, and prep work that a divided sink cannot fit.
• 80% quartz / 20% acrylic resin construction is highly resistant to scratches, stains, chips, and heat up to 535°F in daily kitchen use.
• UV-stabilized White finish holds its color against natural and artificial light exposure over years of use.
• Standard 3-1/2 inch drain opening accepts common basket strainers and disposal flanges without adapter fittings.
• 25-year warranty backs the sink against manufacturing defects for long-term confidence in the purchase.
• Bottom grid and basket strainer included protect the bowl floor and get the sink ready to use from day one.
Built For the Jobs a Divided Sink Turns Away
A single-bowl layout earns its place in kitchens that regularly deal with large cookware. Full-size sheet pans sit flat on the included bottom grid. A 12-quart stockpot fills and drains without having to be tilted past a center divider. Large cutting boards rinse clean without contorting to fit half a basin. Households that batch-cook, bakers working with large mixing bowls, and anyone who hand-washes oversized equipment will find the uninterrupted footprint does the work that a 50/50 or 60/40 bowl splits between stations.
The undermount installation keeps the countertop surface continuous to the bowl edge, making cleanup straightforward: food and water sweep directly into the basin rather than catching on a rim. The faucet and any soap dispenser mount through the countertop behind the sink, so the deck stays clear.
Quartz Composite Construction and the White Finish
The QU-712 is made from 80% natural quartz crystals bound in 20% high-performance acrylic resin, the same material Karran uses across its QU undermount line. The composite is highly resistant to the scratches, stains, chips, and heat that kitchen use produces, and it handles temperatures up to 535°F. The White colorway is UV-stabilized, so the finish resists the yellowing that can develop on untreated white sinks placed near windows or under sustained light exposure. The surface has a consistent, low-sheen texture throughout the composite body, meaning minor surface wear does not expose a different color underneath.
Where the QU-712 Fits
This sink is sized for a 36-inch sink base cabinet and suits kitchen renovations and new builds where the countertop is quartz, granite, or solid surface. Undermount installation on laminate is not in scope for this model — that path belongs to Karran's Q Series seamless line. Designers specifying a large-format primary sink for a high-use kitchen, cabinet shops roughing in a complete sink base, and homeowners upgrading from a smaller or divided bowl will all find this a straightforward choice. The included bottom grid protects the bowl during heavy use, and the basket strainer covers the standard 3-1/2 inch drain opening without a separate trip to the hardware store.
Frequently Asked Questions
Is the QU-712 suitable for a laminate countertop?
No. The QU series is documented for installation in quartz, granite, and solid surface countertops. For a seamless laminate application, Karran's Q Series is the right line.
Does the faucet mount through the sink or the countertop?
Through the countertop. The QU-712 has no faucet deck, so faucet holes are drilled in the countertop material behind the bowl. Plan hole placement before the countertop is cut.
What ships in the box?
The sink arrives with a bottom grid and a basket strainer. A drain assembly and mounting template are not included; verify the cutout dimensions against the actual sink before cutting.
Does the UV stabilization mean I can install this under a skylight?
UV stabilization is designed to resist color shift from sustained light exposure, which makes a bright, window-adjacent or skylit location a reasonable fit. No material is entirely immune to prolonged direct sunlight, but the stabilized resin holds up significantly better than unstabilized whites.
What is the minimum cabinet size?
The QU-712 requires a 36-inch minimum sink base cabinet. Confirm the cabinet opening before ordering.
One Basin, Ready to Work
The QU-712 clears the countertop of dividers and gives the primary wash station maximum working space — backed by quartz composite durability, a UV-stable White finish, and a 25-year warranty that keeps the investment protected for years of heavy kitchen use.
