    Karran 32"W x 19-1/2"D Quartz White Single Bowl Undermount Sink - QU-712-WH

    Description

    Karran QU-712-WH Undermount Sink For New Countertops

    Karran QU-712-WH undermount sink is a quartz white single bowl sink designed for new kitchen countertops, so installers get a defined cutout plan on fresh stone work without dealing with an existing opening. External bowl dimensions of 32-1/2 inches by 19-1/2 inches by 9 inches create a generously sized work area, giving room for larger pots while maintaining clear edges for sealing to the countertop. Internal bowl dimensions of 30 inches by 15-3/4 inches by 9 inches define the actual usable basin space, helping lay out faucet, waste, and surrounding cabinet clearances accurately. The sink bowl surface has a matte finish, which affects the final look at the counter and provides a consistent appearance across the interior. Manufactured from 80 percent crushed quartz plus 20 percent acrylic resin, this sink uses a dense composite material that supports everyday kitchen use where impact and thermal changes are common.

    Quartz Sink Details That Support Daily Use

    • Manufactured from 80 percent crushed quartz plus 20 percent acrylic resin, this composite construction provides a solid-feeling bowl, which supports regular kitchen work where dropped utensils and hot water cycles are routine.
    • External bowl dimensions of 32-1/2 inches by 19-1/2 inches by 9 inches set the overall footprint, guiding cabinet selection and allowing layout of neighboring appliances and base units around a known sink size.
    • Internal bowl dimensions of 30 inches by 15-3/4 inches by 9 inches define the working basin, helping determine how cookware fits and how much depth is available for filling, soaking, and rinsing tasks.
    • A 3-1/2 inch waste opening matches a standard drain size, simplifying drain selection and allowing straightforward connection planning beneath the sink cabinet.
    • The sink bowl surface has a matte finish, which gives the interior a consistent non-gloss appearance that influences light reflection at the counter and the visual match with surrounding surfaces.
    • All external dimensions are approximate to 1/4 inch, so designers and fabricators can plan tolerances in their stone cutouts and cabinet layouts around the stated sizes.

    Undermount Installation And Rim Design Details

    Undermount installation is required for this Karran quartz sink, so the bowl mounts beneath the countertop for a flush interior transition that supports easy wiping from counter into basin. The sink may not be top mounted, keeping the installation method consistent with stone fabrication workflows focused on undermount hardware. This sink can only be installed in new countertops, not existing countertops with an existing sink cutout, which directs it to remodels or new builds where the fabricator controls the cut shape. The 1-1/4 inch by 3/4 inch machined resin matrix rim provides a defined bearing surface against the underside of the stone, supporting adhesion and alignment along the countertop edge.

    Using This Quartz Undermount Sink In The Kitchen

    Where This Karran Quartz Sink Fits Best

    This Karran quartz kitchen sink is part of the Quartz Sinks product class, aligning it with stone and solid-surface style installations where composite bowls are preferred. The sink may be undermounted to all stone products, so fabricators working with granite, quartz, or similar materials can specify a single bowl option that suits those tops. A recommended 1/8 inch overhang at the countertop edge provides a small reveal of stone over the bowl, guiding polish and edge detail decisions at the shop. The option for flush installation allows the stone edge to meet the sink rim directly, supporting design choices where a continuous line from countertop into bowl is desired.

    Details That Support Clean Mounting And Layout

    Single bowl undermount installation keeps the working area uninterrupted, which simplifies faucet and accessory spacing along the back of a 32-1/2 inch wide opening. The 1-1/4 inch by 3/4 inch machined, resin matrix rim is engineered as a uniform surface around the perimeter, helping maintain consistent support under all stone products during bonding. A 3-1/2 inch waste opening focuses the drain location within the 30 inch by 15-3/4 inch interior, so base cabinet plumbing and disposal planning can follow standard kitchen layouts. Digital templates for CNC machines are available at www.karran.com, allowing shops that use CNC equipment to align their cutting paths with the sink geometry. Being a quartz white sink in the kitchen and bath cabinet accessories category ties it directly to cabinet and countertop packages, giving designers a defined bowl option that coordinates with other Karran components.
