A Gray Quartz Undermount Kit Built for the Busy Two-Station Kitchen
The Karran QU-810 is a double equal bowl quartz undermount kitchen sink in Gray, measuring 32 by 19-1/2 by 9 inches and sold as a complete -PK1 kit that includes stainless steel basket strainers, a bottom grid, and Luster Pro oil. Designed for undermount installation in quartz, granite, and solid surface countertops, it brings a clean, rimless look to the main wash station in any kitchen renovation or cabinet-shop build.
Key Features
• Quartz composite construction delivers the highly scratch, stain, chip, and heat resistance Karran's 80% quartz / 20% acrylic resin formula is known for.
• Double equal bowl layout splits the 32-inch sink evenly for simultaneous wash-and-rinse or prep-and-wash workflows.
• 9-inch bowl depth accommodates large stockpots, roasting pans, and sheet pans with room to spare.
• Flat mounting rim with no faucet deck mounts cleanly beneath the countertop, with the faucet drilling through the countertop surface behind the bowl.
• -PK1 kit includes stainless steel basket strainers, a bottom grid, and Luster Pro oil so the sink is ready to install and protect right out of the box.
• Gray finish pairs naturally with both light and dark countertop materials and holds its tone against everyday kitchen grime.
Where the Two-Bowl Layout Earns Its Keep
A 50/50 split at 32 inches gives each bowl a working footprint that handles real kitchen tasks: one side for wash water and the other for rinsing, air-drying, or a colander. That configuration suits households that hand-wash dishes regularly, kitchen renovations where a dedicated prep side is part of the design brief, and builder-spec projects where a double bowl is expected at the main sink position. The 9-inch depth means most cookware drops straight in without the awkward tilting a shallower bowl requires. Because the faucet mounts through the countertop rather than through a sink deck, the full width of each bowl stays unobstructed, and countertop drilling can be positioned wherever the faucet's reach works best for the layout.
Quartz Composite in a Color That Works Every Day
Karran builds the QU-810 from a blend of 80% natural quartz crystals and 20% high-performance acrylic resin, a combination the manufacturer describes as highly scratch, stain, chip, and heat resistant. The Gray colorway runs through the full thickness of the material, so normal kitchen wear — utensil drops, pan corners, everyday abrasion — does not reveal a contrasting core. Gray sits in a practical middle ground: it does not read as stark as Matte Black or as fragile-looking as White, and it holds its tone in kitchens with both light stone and darker laminate surfaces. The flat undermount rim keeps no rim visible above the counter, so the countertop material and edge profile stay the visual focus. The included Luster Pro oil is formulated for quartz composite surfaces and is the recommended first step after installation to condition the bowl and maintain the finish over time.
The Right Sink for Countertop Fabricators and Renovating Homeowners
Cabinet shops specifying a sink for a laminate or solid surface countertop build should note that the QU series is a standard undermount line, not Karran's seamless Q Series — the faucet deck is absent and the rim is flat for a clean reveal, but the seamless integration method documented for the Q Series does not apply here. For quartz, granite, and solid surface countertops, this is a straightforward undermount installation with a professional result. Homeowners replacing an existing sink in a stone or quartz counter will find the 32 by 19-1/2 inch footprint compatible with most 33-inch sink base cabinets, though confirming the cutout dimensions against the actual cabinet before cutting is always the right move. The kit format removes the most common after-order friction: strainers and a grid are already in the box.
Does this sink install seamlessly in laminate countertops?
No. The QU-810 is part of Karran's QU undermount series, which is designed for standard undermount installation in quartz, granite, and solid surface countertops. Karran's seamless laminate and solid surface installation method applies to the Q Series, not the QU Series. If seamless laminate integration is the goal, look at the Q Series lineup instead.
Where does the faucet mount on this sink?
The QU-810 has no faucet deck, so the faucet mounts through the countertop surface behind the sink. The number and placement of the countertop drillings are determined during fabrication, which gives flexibility for single-hole, three-hole, or bridge faucet configurations depending on the faucet chosen.
What comes in the -PK1 kit?
The -PK1 kit includes stainless steel basket strainers, a bottom grid sized for this sink, and Luster Pro oil. Mounting clips and a cutout template are not included with QU Series sinks; those are supplied or sourced during the countertop fabrication process.
Will this sink fit a standard 33-inch sink base cabinet?
The QU-810 measures 32 inches wide overall, which is sized for most 33-inch sink base cabinets. Because sink base dimensions and countertop cutouts vary by manufacturer, verify the actual cabinet and countertop opening against the sink's dimensions before cutting.
One Kit, Two Bowls, Ready for the Counter
The QU-810 Gray kit puts a durable, practical double bowl undermount sink into a single order — no separate strainer or grid trip required — so the install can move forward the day it arrives.
