The Karran QT-812 is a large single bowl quartz composite kitchen sink that installs as a drop-in from above, making it compatible with virtually every countertop material — laminate, granite, quartz, solid surface, and tile. Its 33 by 22 inch footprint delivers a generous single bowl workspace in a Gray finish that blends with contemporary and transitional kitchen designs alike.
• Top mount drop-in installation seats the sink from above into a cutout, fitting new countertops and retrofit projects across all countertop materials.
• Large single bowl configuration provides an uninterrupted 33 by 22 inch basin for washing oversize pots, sheet pans, and large cookware without a divider in the way.
• 80% quartz, 20% acrylic resin construction gives the bowl high resistance to scratches, stains, chips, and heat during everyday kitchen use.
• Gray quartz finish is a uniform-through color, so chips and surface wear do not expose a contrasting substrate beneath.
• -PK1 kit includes basket strainers, bottom grid, and Luster Pro oil so the sink arrives ready for the first use without a separate accessory order.
• 9-inch bowl depth accommodates tall stock pots and deep dish cleaning without splashing onto the counter.
Top mount installation is the practical path for kitchen remodels where the existing countertop stays in place. The visible rim sits on the counter surface and covers the cut edge completely, which means a less demanding cutout — no exposed stone edge to finish, no bevel-bit trimming required. Trace the perimeter, mark the cut line, drill a starter hole, and complete the opening with a jigsaw. The QT-812's large single bowl layout suits households that hand-wash cookware, prep large batches, or simply prefer an open basin without a center divider. It's equally at home in a new build where the buyer wants a durable quartz bowl without a seamless fabrication budget.
Quartz composite combines the hardness of natural quartz crystals with the flexibility of acrylic resin, producing a bowl that resists the impact of dropped utensils, the staining of coffee and wine, and the heat of a pot pulled directly from the stove. The Gray color runs through the full thickness of the material, keeping the look consistent over years of use. Unlike stainless steel, quartz composite does not ring or transfer noise when a pan contacts the bowl. The Luster Pro oil included in the kit maintains the surface's appearance and is Karran's recommended care product for their quartz sinks.
Cabinet shops outfitting a kitchen remodel on an existing laminate or tile counter will find the drop-in method the fastest path to a finished installation. Contractors working across a mix of countertop materials on the same job can specify one SKU with confidence rather than matching a sink to a countertop type. Homeowners replacing a worn drop-in sink get a material upgrade — quartz composite in place of stainless or acrylic — without altering the countertop. Designers specifying a Gray palette in a transitional kitchen get a neutral, matte bowl that coordinates with gray cabinetry, white quartz tops, and brushed metal hardware without competing for attention.
Yes. The top mount method places the rim on top of the counter surface and covers the cut edge, which makes it well suited to laminate. No edge finishing or seamless fabrication is required.
The kit ships with stainless steel basket strainers, a bottom grid, and Luster Pro oil. A drain assembly and faucet are not included and are purchased separately.
The QT-812 is a top mount quartz sink; faucet holes are drilled through the countertop behind the sink rather than through a deck on the sink itself. Confirm the number and spacing of holes with your faucet's mounting requirements before cutting.
Karran QT Series spec sheets do not list a paper template as included. Use the actual sink to trace the cutout perimeter, then mark and cut 1/2 inch inside the line.
Karran's Gray quartz (GR) is a sink-material color, not a coated finish. Coordinate faucets and accessories by selecting Karran's compatible finish finishes separately; exact visual match across materials is not guaranteed.
The QT-812 brings quartz composite durability to the simplest installation path in kitchen sink work — drop it in, clamp it down, done. The large single bowl and included kit make it a one-stop solution for remodels and new builds where performance and ease of fit both matter.
