    Description

    Karran Quartz Undermount Sink For Compact Kitchens

    Karran quartz undermount sink defines this Karran 24-3/8 inch W x 19-1/8 inch D single bowl undermount sink in gray, giving installers a precise, compact option for smaller kitchen layouts where every inch of cabinet space matters. The sink is designed for installation into quartz, granite and solid surface countertops, so it drops directly into the solid-surface projects where Karran quartz sinks are typically specified. Its single bowl undermount format creates a continuous countertop surface, which simplifies cleanup around the sink edge in everyday use. This model is part of Karran's quartz sinks product class, aligning with projects that already use engineered stone. The sink is described as a kitchen sink in quartz material, so it fits standard kitchen washing tasks. With Karran branding and the QU-820-GR part number, it matches jobs that need a clearly identified, repeatable sink spec on project documents.

    Quartz Sink Details That Support Daily Use

    • The sink is made from 80% natural quartz crystals and pure acrylic resin, creating a dense composite structure that supports demanding kitchen use where the bowl regularly handles pots, pans, and dishware.
    • The durable quartz material is non-porous, preventing the spread of germs and bacteria, which supports hygiene expectations in residential kitchens where food prep and cleanup happen in the same workspace.
    • The material is extremely stain, scratch, abrasion and impact resistant, so the bowl surface better maintains its appearance when it sees repeated loading of cookware, utensils, and cleaning tools over time.
    • The heat resistant rating is up to 535 F, and the sink can withstand rapid temperature changes from hot and cold water, which allows typical kitchen workflows like moving hot cookware and running cold rinses without stressing the bowl material.
    • The sink is gray quartz, providing a neutral, stone-like appearance that coordinates with many quartz, granite, and solid surface countertop colors in contemporary kitchen designs.

    Undermount Sink Fit, Depth, And Drain Layout

    The sink is designed specifically as an undermount unit, so it attaches beneath the countertop, creating a flush transition that supports wiping debris straight from the counter into the bowl. The rear drain location provides more storage room in the cabinet below, because plumbing can be routed toward the back, leaving usable space near the front of the 27 inch sink base cabinet. The bowl depth is 9 inches, providing plenty of room to accommodate cookware and daily dish loads while still fitting within the cabinet height envelope. The minimum cabinet size required is a 27 inch sink base cabinet, which sets a clear casework requirement for layout planning. The drain opening size is 3-1/2 inches, aligning with standard kitchen drain fittings and plumbing terminations at the base of the sink.

    How This Karran QU-820-GR Sink Performs In Use

    Where This Karran Quartz Undermount Sink Fits Best

    This Karran 24-3/8 inch W x 19-1/8 inch D quartz single bowl undermount sink fits into quartz, granite and solid surface countertops, so it aligns with solid-surface kitchens, wet bars, and auxiliary prep areas built around engineered stone. The specified minimum 27 inch sink base cabinet requirement means it suits compact base cabinet layouts often used in smaller kitchens, apartments, or secondary work zones. The rear drain location opens up more storage room in the cabinet below, which is useful in tight installations where space for cleaning supplies or small pullout organizers is critical. With an approximate weight of 29 lbs, the sink has a substantial feel that matches the expectations of a quartz sinks product class while remaining manageable during handling and positioning. The gray quartz finish works with a wide range of stone countertop tones, supporting visual continuity in multi-surface kitchen designs.

    Details That Help Deliver Consistent Sink Installations

    The sink is designed for installation into quartz, granite and solid surface countertops, so fabricators working these materials can cut a consistent undermount opening and expect the sink to integrate cleanly with their standard methods. All external dimensions are approximate to 1/4 inch, which provides a defined tolerance band that helps templating and countertop cutout planning. The durable quartz material is non-porous, preventing the spread of germs and bacteria, which supports long-term performance when users routinely expose the bowl to food residues and standing water. Its extreme resistance to stain, scratch, abrasion and impact means routine use with metal cookware and utensils is less likely to affect the bowl surface, maintaining a predictable appearance across multiple installations. The sink is compatible with most garbage disposals, so standard disposal flanges and mounting hardware can typically be integrated into the 3-1/2 inch drain opening without altering the sink body. The heat resistance up to 535 F, combined with tolerance for rapid temperature changes from hot and cold water, supports workflows where hot pans and cold rinses cycle through the bowl during daily kitchen use.
