    Karran 24-3/8"W x 19-1/8"D Quartz Gray Single Bowl Undermount Sink, 20 Per Pallet - QU-820-GR [Nested 20]

    Description

    Karran Quartz Single Bowl Undermount Sink Use

    Karran quartz single bowl undermount sink identifies this as a single bowl undermount sink in quartz from Karran, so it serves as a solid basin solution for kitchen or bath cabinets where an undermount install is preferred. The 24-3/8 inch wide by 19-1/8 inch deep size sets the footprint, which matters when planning cabinet layouts or matching to existing cutouts. Being a single bowl design creates one open working well, which suits washing larger cookware without dividers getting in the way. The gray color defines the finished look, letting this sink coordinate with a range of countertop and cabinet finishes. As a quartz sink in the quartz sinks product class, it fits design schemes that call for a solid, stone-like appearance in the work area. The Karran brand and specific QU-820-GR model tie the sink to a consistent manufacturing standard for repeat use across multiple jobs.

    Quartz Sink Details That Support Daily Work

    • Construction from 80 percent natural quartz crystals and pure acrylic resin creates a dense, engineered material, which matters on the job for a consistent feel and predictable cutting and mounting behavior in solid-surface installations.
    • Heat safe up to 535 F sets a clear temperature threshold, which matters when hot pots or pans contact the basin during normal kitchen use without immediately affecting the sink surface under rated conditions.
    • Ability to withstand rapid temperature changes from hot and cold water defines thermal performance, which matters where fast transitions between hot and cold flows happen repeatedly during cleanup.
    • Durable quartz material being non-porous prohibits the spread of germs and bacteria, which matters for keeping the sink surface more sanitary in food prep and cleaning tasks.
    • Rear drain locations free space toward the front and center of the cabinet, which matters when planning under-sink storage or routing plumbing where space is often tight.
    • 9 inch deep bowls provide plenty of room to accommodate cookware, which matters when handling larger pots, pans, and trays without constant splashing over the counter edge.

    Undermount Quartz Sink Fit And Layout Planning

    This quartz gray single bowl undermount sink is defined as an undermount model, so it installs beneath the countertop surface and relies on a properly sized cutout matching the 24-3/8 inch by 19-1/8 inch dimensions. Those dimensions guide layout when positioning the sink within a cabinet run, because the cabinet opening must accommodate the sink body and support structure. The undermount configuration leaves the deck of the countertop clear, which supports wiping water and debris directly into the basin without catching on a rim. The rear drain locations concentrate pipework toward the back of the cabinet, which keeps more uninterrupted space toward the front for cleaning supplies or other stored items. The 9 inch bowl depth defines how far the basin projects below the countertop, which matters when coordinating trap height and overall plumbing alignment inside the cabinet.

    Using This Karran QU-820-GR Quartz Sink On Projects

    Where This Quartz Gray Undermount Sink Fits Best

    The Karran QU-820-GR quartz sink is identified as part of the quartz sinks product class, so it targets kitchens or baths where a solid, stone-like sink surface is desired alongside stone or composite tops. The 24-3/8 inch width and 19-1/8 inch depth define a compact rectangular footprint, which suits standard base cabinets that need a functional basin without consuming the entire cabinet run. Its single bowl layout focuses all space into one 9 inch deep well, which works well in prep areas that handle larger pans, baking trays, and stock pots needing full-depth immersion. The gray color gives a neutral, modern appearance, which blends into many cabinet and countertop combinations without dictating a specific color scheme. As a quartz undermount sink, it aligns with installations that want the sink visually integrated under solid-surface, stone, or engineered countertops.

    Details That Support Repeatable Layouts And Installs

    The construction from 80 percent natural quartz crystals and pure acrylic resin defines the engineered material, which gives installers a predictable substrate when cutting countertop openings and shaping edges around the sink. Being heat safe up to 535 F describes how the basin tolerates high-temperature items, which matters for crews designing kitchens that routinely see hot cookware moved directly from cooking surfaces into the sink. The ability to withstand rapid temperature changes from hot and cold water clarifies performance during frequent, alternating hot and cold rinses, which supports long-term use in active kitchens. The non-porous quartz surface prohibiting the spread of germs and bacteria defines how the basin interacts with moisture and debris, which matters in environments focused on cleanable surfaces around food prep. Rear drain locations concentrate plumbing at the back of the cabinet, which supports consistent under-sink layouts from job to job when standardizing trap and supply placements. The 9 inch bowl depth sets a repeat vertical dimension, which helps keep drain connections and clearances consistent across multiple installs using the same QU-820-GR model.

    Is this Karran QU-820-GR model designed as an undermount sink?

    How does the rear drain location affect cabinet storage?

    The rear drain location moves the plumbing toward the back of the cabinet, leaving more usable space toward the front for storage or other components.
