A Large Quartz Undermount Bowl For Serious Kitchen Work
The Karran QU-812 is a large single bowl quartz composite undermount kitchen sink designed for everyday cooking, cleaning, and prep in kitchens where counter space is prized and workspace in the bowl is never enough. Offered here in White, it ships as a -PK1 kit with basket strainers, a bottom grid, and Luster Pro oil included.
Key Features
• Quartz composite construction blends 80% natural quartz crystals with 20% high-performance acrylic resin for a sink that resists scratches, stains, chips, and heat.
• Large single bowl configuration gives you an uninterrupted 32-1/4 by 19-1/4 inch footprint with a 9 inch depth, accommodating full sheet pans and large stockpots without divider interference.
• Undermount installation positions the sink beneath the countertop so the counter edge wipes clean and no rim traps water or debris above the surface.
• -PK1 kit contents include stainless steel basket strainers, a bottom grid, and Luster Pro oil, so the sink is ready to use from the first day.
• White finish suits both traditional and transitional kitchen designs, coordinating easily with painted cabinetry and light-toned countertops.
Built for High-Volume Kitchen Use
Single bowl sinks earn their place in kitchens where the work is real: roasting pans that will not lie flat in a divided basin, a holiday's worth of produce rinsed under a single stream, or a deep pot that needs to soak overnight without being shifted to a rinse side. The QU-812's 9 inch depth keeps splashing contained and handles the tall items that shallower bowls push out at an angle. The flat undermount rim integrates with quartz, granite, and solid surface countertops using standard undermounting methods, with the faucet and any soap dispenser drilled through the countertop behind the bowl since the sink carries no deck of its own.
Material and Durability
Quartz composite at this ratio — 80% quartz to 20% acrylic resin — produces a dense, non-porous surface that resists the staining and scratching that a glossy porcelain or lighter acrylic bowl would show over time. The White color runs throughout the material rather than sitting as a surface layer, so minor surface contact does not expose a contrasting core. The included Luster Pro oil is Karran's care product for the quartz surface, used to maintain the finish's appearance after installation and periodically as the sink breaks in with use. The bottom grid lifts dishes and cookware off the bowl floor, protecting both the quartz and your dishes during everyday use.
Who This Sink Fits
The QU-812 suits kitchen remodels and new builds where the countertop is quartz, granite, or solid surface and the homeowner or designer is choosing a single bowl for maximum interior workspace. Cabinet shops specifying kitchen packages, designers sourcing a clean white undermount for a painted or transitional kitchen, and contractors installing a full-size sink base will all find the dimensions and mounting method straightforward. At 32-1/4 inches wide, the sink fits a standard 33 inch or larger sink base cabinet. This is a dry-indoor residential installation; pair it with a countertop material and mounting method appropriate for the project.
Frequently Asked Questions
Does this sink install seamlessly in a laminate countertop?
No. The QU-812 is a standard undermount sink. Seamless laminate and solid surface installation is specific to Karran's Q Series. The QU-812 undermounts in quartz, granite, and solid surface countertops using conventional clips and mounting hardware.
Does the kit include a drain or template?
The -PK1 kit includes stainless steel basket strainers, a bottom grid, and Luster Pro oil. A drain template and mounting clips are not documented as included; check with your countertop fabricator about template and clip requirements for your countertop material.
Where does the faucet mount?
The QU-812 has no faucet deck. The faucet, soap dispenser, and any other accessories mount through the countertop. Plan your countertop drillings before cutting the countertop.
What minimum cabinet size does this sink require?
At 32-1/4 inches wide overall, the sink fits a 33 inch or larger sink base cabinet. Confirm the exact minimum cabinet size with the spec sheet or your fabricator before ordering cabinetry.
One Bowl, No Compromises
The QU-812 White delivers a clean, large-format quartz workspace that installs underneath the counter and stays out of the way — exactly what a working kitchen needs when the job is bigger than a divided bowl can handle.
