A Drop-In Quartz Kitchen Sink Designed for Two-Station Work
The Karran QT-810 is a top mount quartz composite kitchen sink with two equal bowls, sized to fit a standard 33-inch sink base. It installs from above into any countertop material — laminate, tile, stone, or solid surface — making it a practical choice for kitchen remodels where the countertop stays and the sink gets replaced, or for new builds where the fabricator wants a fast, clean installation without seamless bonding. The kit includes basket strainers, bottom grids, and Luster Pro oil so the sink is ready to put to work from the first day.
Key Features
• Quartz composite construction: Made from 80% natural quartz crystals and 20% acrylic resin, the bowl surface is highly resistant to scratches, stains, chips, and heat.
• Equal double-bowl layout: Two identical basins give each side of the sink equal working depth and width, supporting dedicated wash and rinse stations.
• Top mount installation: The sink drops into a countertop cutout and seats on its perimeter rim, compatible with all countertop materials without specialized seamless bonding methods.
• Kit includes basket strainers, bottom grids, and Luster Pro oil: The -PK1 pack delivers the day-one essentials alongside the sink bowl.
• White finish: A clean, neutral color that pairs easily with white or light-toned countertop and cabinetry selections.
• 9-inch bowl depth: Deep enough for full-size cookware and sheet pans without water splashing onto the counter.
Where This Sink Earns Its Place in the Kitchen
An equal double-bowl layout suits kitchens where two people often work at the sink at the same time, or where a single cook regularly runs both wash and rinse water simultaneously. Unlike a large/small configuration that commits most of the interior to one dominant basin, the QT-810 divides the 33-inch footprint evenly — each bowl carries the same capacity. That symmetry also means a grid fits each side without cross-shopping bowl-specific accessories.
The top mount method opens the door to countertop materials that a seamless install does not support. Existing tile, natural stone, or a newly fabricated laminate top all accept this sink without modification to the installation method — trace the cutout, cut, and drop the sink in. Cabinet shops retrofitting sinks into finished kitchens or setting sinks during a countertop-only replacement will find the top mount path significantly faster than an undermount sequence requiring adhesive cure time.
Quartz Composite Inside and Out
The bowl material — 80% quartz, 20% acrylic resin — is not a surface coating. The composition runs through the full thickness of the sink, which means chips and scratches stay shallow and the color holds. Karran describes the material as highly resistant to scratches, stains, chips, and heat, making it a durable daily surface for a busy kitchen. White quartz composite takes on everyday use without the same visible wear rate as a white enamel or porcelain finish, and it does not require the same careful handling that a cast iron sink demands during installation.
The included Luster Pro oil is formulated to condition and protect the quartz surface, and the supplied bottom grids keep the bowls free of contact marks and scoring from heavy pots and pans. Both ship in the kit, so the sink is properly equipped on install day.
The Right Fit for Remodels, Retrofits, and New Builds
Homeowners replacing a worn drop-in sink without disturbing the surrounding countertop will find the QT-810 a straightforward swap. Designers specifying a white, equal-bowl sink for a transitional or clean-lined kitchen have a durable quartz option here rather than a stainless or enamel alternative. Cabinet shops building out kitchens to spec can rely on the kit configuration to minimize on-site sourcing — the strainers and grids arrive in the same box. The 33-inch footprint and 9-inch depth suit the primary wash station in most residential kitchens, and the faucet mounts through the countertop behind the sink rather than through a deck on the sink itself, giving the installer flexibility in faucet selection.
Frequently Asked Questions
Does this sink work with existing laminate countertops?
Yes. The top mount installation method is compatible with laminate, tile, stone, and solid surface countertops. The sink rests on its perimeter rim and seals to the counter surface with silicone, so no specialized bonding process is required.
What does the -PK1 kit include?
The kit includes the QT-810 sink, stainless steel basket strainers, bottom grids for both bowls, and Luster Pro oil. A drain assembly and faucet are not included and are purchased separately.
Is a template included to guide the countertop cutout?
Karran QT Series spec sheets state that no paper template is included. The standard method is to trace the sink rim directly onto the countertop, mark the cut line inside the perimeter, drill a starter hole, and cut with a jigsaw. A DXF file may be available for CNC cutouts.
Where does the faucet mount on this sink?
The QT-810 does not have a faucet deck, so the faucet and any accessories mount through the countertop behind the sink. This gives you flexibility to drill one, three, or four holes to match your faucet's configuration.
What minimum cabinet size does this sink require?
The QT-810's 33-inch overall width is designed for a 33-inch sink base cabinet. Confirm the sink's full dimensions against your cabinet opening before cutting.
Quartz Performance, Drop-In Simplicity
The QT-810 delivers the durability of quartz composite in a format that fits the broadest range of countertops and installation scenarios — no seamless bonding, no countertop-material restrictions, and no day-one parts run to gather strainers and grids. It's a complete, ready-to-install double bowl sink for the kitchen that takes on heavy use without showing it.
