A Generous 32-Inch Basin for the Hardest-Working Kitchen Station
The Karran QU-812 is a large single bowl undermount kitchen sink in quartz composite, sized at 32-1/4 by 19-1/4 by 9 inches and offered here in White. It undermounts beneath stone, quartz, and solid surface countertops with a flat concealed rim, giving the finished counter a clean edge and the cook an uninterrupted basin deep enough to handle full-size cookware.
Key Features
• Quartz composite construction (80% quartz, 20% acrylic resin) delivers high resistance to scratches, stains, chips, and heat during everyday use.
• Large single bowl layout at 32-1/4 by 19-1/4 inches accommodates sheet pans, stock pots, and oversized cutting boards without a center divider in the way.
• 9-inch bowl depth contains splashing and fits tall pots upright under a running faucet.
• Flat-rim undermount design positions the sink beneath the countertop for a wipe-clean edge and no exposed rim ledge to trap debris.
• White finish coordinates with light cabinetry, tile, and countertop colors across traditional and transitional kitchen styles.
Where This Sink Does Its Best Work
A single bowl this wide earns its place at the primary kitchen wash station, where divided bowls tend to limit what fits inside. Sheet pans lie flat on the bottom. Stock pots and roasting pans drop in without wedging against a divider wall. Meal-prep cleanup, hand-washing large serving pieces, and rinsing produce all happen in one basin without switching sides. The 9-inch depth keeps the spray inside the bowl even when the faucet runs at full pressure, which matters more when there is no second bowl to block the splash.
This is also a natural choice for kitchen renovations where the countertop is stone, engineered quartz, or solid surface. The flat rim sits flush against the underside of the slab, and the faucet mounts through the countertop behind the sink rather than through a deck on the sink itself, which is the standard path for undermount stone installs.
Quartz Composite Construction and the White Finish
Karran builds these bowls from 80% natural quartz crystals bound in 20% acrylic resin. The blend produces a dense, non-metallic surface that resists the day-to-day punishment of a working kitchen: hot pans set down from the range, staining from coffee and red wine, the constant scraping of knives and metal utensils. Resistance does not mean indestructible, but quartz composite holds up notably well compared to coated steel or porcelain surfaces that chip and show wear at the rim.
The White finish suits kitchens where the sink needs to recede into the design rather than become a focal point. It pairs cleanly with white or grey countertops, subway tile, and painted cabinetry, and it reads as neutral enough to sit beside stainless appliances without clashing.
A Good Fit for Contractors, Designers, and Serious Home Kitchens
Cabinet shops and contractors building kitchen projects around stone or engineered quartz countertops will find the QU-812 a straightforward spec: the undermount profile is compatible with the installation methods standard for those materials, and the quartz composite surface does not require the care protocols that a polished stainless or cast iron bowl demands. Designers specifying for a transitional or traditional kitchen get a proven material in a classic finish. Homeowners doing a renovation get a basin large enough to handle a full household's dishes and cookware without regret about choosing a divided bowl. Note that template and mounting clips are not included with this sink and are sourced separately for the countertop type.
Frequently Asked Questions
Does the QU-812 work under a granite or engineered quartz countertop?
Yes. The flat rim is designed for undermounting beneath solid stone, engineered quartz, and solid surface countertops. The faucet mounts through the countertop rather than through the sink, which is the standard approach for those materials.
Is a template or mounting hardware included?
No. Template and mounting clips are not included with the QU-812. Your fabricator or countertop installer will supply the appropriate fastening method for the countertop material.
What is the minimum cabinet size this sink requires?
The overall width of the QU-812 is 32-1/4 inches. Verify the minimum cabinet size with Karran's specification sheet for this model before ordering, since cabinet fit depends on the overall sink dimensions and your specific base cabinet configuration.
Is a drain or grid included?
The QU-812 in this listing is a bare sink; a drain, basket strainer, and bottom grid are sold separately. Karran offers model-matched accessories — confirm compatibility by model number before ordering.
Can quartz composite handle hot pots set directly on the surface?
Karran describes quartz composite as heat resistant. Routine contact with warm cookware is within normal use, but sustained extreme heat from a pot directly off a high burner is outside the intended use for any composite sink surface.
One Basin, No Compromises
The QU-812 gives a serious kitchen a proper work sink: deep enough for tall cookware, wide enough for full sheet pans, and built from a material that holds its look through years of daily use without demanding special care.
