    Karran 32-1/2"W x 19-1/4"D Quartz Gray Single Bowl Undermount Sink, 20 Per Pallet - QU-812-GR [Nested 20]

    Description

    Karran Quartz Single Bowl Undermount Sink For Kitchens

    Karran quartz single bowl undermount sink is a 32-1/2 inch wide by 19-1/4 inch deep gray quartz sink designed for undermount installation in kitchen and bath cabinetry. The sink is made from 80% natural quartz crystals combined with pure acrylic resin, creating a dense composite that performs like stone in day-to-day use. This single bowl layout gives one large working basin, which suits washing bigger pots and pans without dividing space. As a quartz sink in a gray finish, it offers a neutral, consistent look that pairs with a wide range of cabinet colors and countertops. The product is part of Karran's quartz sinks line, identified as model QU-812-GR, aligning it with other professional-grade kitchen sink options from the same manufacturer for project standardization.

    Key Quartz Sink Details That Support Daily Use

    • The sink is made from 80% natural quartz crystals and pure acrylic resin, creating a non-porous surface that resists absorbing moisture, which supports straightforward cleanup and reduces places for germs and bacteria to lodge during regular kitchen use.
    • The quartz material is heat safe up to 535 degrees F and can withstand rapid temperature changes from hot and cold water, so typical cooking and cleanup cycles are handled without thermal shock concerns around the bowl area.
    • The durable quartz construction is described as non-porous, which prohibits the spread of germs and bacteria across the sink surface, supporting hygiene standards in residential kitchens and light commercial applications where cleanliness matters.
    • Rear drain locations shift the drain toward the back of the cabinet footprint, freeing more usable cabinet space under the sink area for waste baskets or storage and keeping the trap further from the front of the cabinet.
    • The bowl depth is 9 inches, providing ample vertical space for stacking cookware, soaking baking sheets, and working with large pots while limiting splash over the countertop edge during higher-volume rinsing.

    Undermount Sink Dimensions And Installation Context

    This Karran QU-812-GR quartz gray single bowl undermount sink has an overall size of 32-1/2 inches wide by 19-1/4 inches deep, giving a generous footprint for standard kitchen base cabinets. As an undermount sink, it is designed to be mounted beneath a compatible countertop cutout so the counter edge forms the rim, creating a flush, wipe-down surface at the sink opening. The 9 inch deep bowl works with this undermount setup to give a substantial working depth without overwhelming the base cabinet interior height. With the drain positioned toward the rear, plumbing is oriented toward the back wall of the cabinet, simplifying alignment with wall stub-outs in many kitchen layouts.

    How This Karran Quartz Sink Fits Real Projects

    Where This Quartz Gray Undermount Sink Performs Best

    The Karran QU-812-GR NESTED 20 quartz sink is a single bowl undermount unit sized at 32-1/2 inches wide by 19-1/4 inches deep, making it a practical choice for standard-width kitchen base cabinets needing a full-size basin. Its gray quartz finish helps it sit comfortably in both light and dark design schemes, giving designers and installers flexibility across multiple projects using similar casework. The 9 inch deep bowl gives meaningful working depth for cleanup stations in residential kitchens, break areas, or similar cabinet-based wet zones. Because the sink material is 80% natural quartz crystals combined with pure acrylic resin, it behaves as a composite surface built for regular water exposure and dish handling. The non-porous nature of the quartz construction prohibits the spread of germs and bacteria across the surface, which supports use in settings where easy-to-clean wet areas are important. Rear drain locations suit layouts where under-sink storage or waste systems are planned, as the drain and trap assembly sit toward the back, leaving more unobstructed front space. As part of Karran's quartz sinks class, this model slots into projects that standardize on composite undermount sinks rather than metal bowls, helping maintain a consistent look and feel from kitchen to kitchen.

    Details That Support Reliable Installation And Workflow

    The Karran quartz single bowl undermount sink is engineered with rear drain locations, which helps installers route plumbing against the back wall of the cabinet, reducing interference with pull-out units or front-placed storage. Its 32-1/2 inch by 19-1/4 inch overall dimension offers a defined footprint that works with typical base cabinet spans, simplifying layout and countertop cutout planning. The 9 inch deep bowl offers enough internal height to submerge cookware while still leaving room for standard drain assemblies and traps within the cabinet. The sink's quartz construction, made from 80% natural quartz crystals and pure acrylic resin, yields a rigid basin that supports stable undermount attachment when used with compatible countertops. Being heat safe up to 535 degrees F, the sink handles exposure to hot water and typical cookware temperatures during daily work, which supports predictable performance during installation demonstrations and client handover. Its ability to withstand rapid temperature changes from hot and cold water limits concerns about sudden thermal stress when water conditions fluctuate. As a non-porous quartz surface that prohibits the spread of germs and bacteria, the interior cleans down efficiently at the end of the workday, helping maintain a professional finish for occupants with minimal ongoing effort.
