The Karran QU-812 is a large single-bowl quartz composite undermount sink built for kitchens where an uninterrupted basin is the priority. Arriving as a complete -PK1 kit, it includes stainless steel basket strainers, bottom grids, and Luster Pro oil so installation day requires one fewer trip to source accessories.
• 80% quartz / 20% acrylic resin construction delivers a bowl that is highly scratch, stain, chip, and heat resistant through everyday kitchen use.
• Large single-bowl configuration provides one uninterrupted basin that accommodates sheet pans, stockpots, and large cutting boards with ease.
• Undermount installation positions the sink beneath the countertop, leaving a clean wipe-to-drain edge with no exposed rim collecting debris.
• Gray finish reads as a neutral that pairs equally well with light stone, dark quartz, and laminate countertop surfaces.
• Kit includes basket strainers, bottom grids, and Luster Pro oil, so the essential components arrive together.
• No faucet deck on the QU Series, meaning the faucet and any accessories mount through the countertop rather than the sink.
A divided bowl forces a choice every time an oversized pot or a full sheet pan needs to be washed. The QU-812 eliminates that compromise. The 9-inch depth gives enough clearance to submerge large cookware fully, and the generous footprint makes it a strong fit for busy primary kitchen stations in both new construction and gut-renovation projects. Cabinet shops building islands or perimeter sink runs benefit from knowing the QU-812 fits a 36-inch minimum base cabinet, keeping it compatible with standard residential cabinetry.
Because the QU Series mounts beneath the countertop, it pairs well with quartz, granite, and solid surface countertop materials. The faucet mounts through the countertop, so the buyer selects a single-hole or spread-fit faucet based on the countertop drilling rather than any holes in the sink itself. Professional installation is recommended for undermount applications.
Karran's quartz composite formula combines 80% natural quartz crystals with 20% high-performance acrylic resin. The result is a non-metallic bowl that does not ring, does not show fingerprints, and does not chip under normal kitchen loads. The Gray color runs through the full depth of the material, so minor surface abrasion does not expose a contrasting base. The included Luster Pro oil is formulated to refresh and protect the quartz surface as part of routine care, extending the bowl's appearance over years of use.
Homeowners who cook regularly and want a single large basin without the maintenance concerns of stainless steel will find the QU-812's quartz composite surface easier to live with. Designers specifying a gray sink that holds its look in a kitchen with mixed finishes can rely on the neutral tone without worrying about spotting or surface wear changing the color story. Cabinet shops and contractors building out sink cabinets in production runs benefit from the kit format: the grids and strainers resolve before the order ships, and there is no separate accessory order to coordinate. The 32-1/4 by 19-1/4 inch footprint fits standard 36-inch sink base cabinetry, making it a predictable spec for both custom and semi-custom installations.
No. The QU-812 is a QU Series sink, which is a standard undermount design with a flat mounting rim. Seamless integration in laminate and solid surface is a Q Series capability. The QU-812 undermounts conventionally in quartz, granite, and solid surface countertops.
The kit ships with stainless steel basket strainers, bottom grids, and Luster Pro oil. Clips and a paper template are not included with QU Series sinks, and a drain assembly is a separate purchase.
The QU-812 has no faucet deck and no pre-drilled holes. The faucet mounts through the countertop. The number and layout of faucet holes are determined by the countertop fabricator based on the buyer's faucet choice.
Yes. Karran's quartz composite construction carries the color through the full depth of the bowl. Light surface abrasion does not reveal a different underlying color.
The QU-812 requires a minimum 36-inch base cabinet to accommodate its 32-1/4 inch overall length.
The QU-812 in Gray delivers a large, durable single bowl with the undermount profile designers and fabricators expect, bundled with the accessories needed to finish the installation cleanly and move on to the next task.
