Karran 24-3/8"W x 19-1/8"D Quartz Bisque Single Bowl Undermount Sink - QU-820-BI

Karran Quartz Undermount Sink For Busy Kitchens

Karran quartz undermount sink gives you a single bowl workspace designed for installation into quartz, granite and solid surface countertops, so it matches the look and strength of the solid-surface jobs you install every day. The sink is made from 80% natural quartz crystals and pure acrylic resin, creating a dense, engineered material that works well in demanding kitchen use. Heat resistance up to 535 F means the bowl handles hot pots and rapid temperature changes from hot and cold water without losing its structural integrity in normal use. The durable quartz material is non-porous, so the bowl surface does not harbor germs and bacteria in micro-pores during daily cleanup. Extremely stain, scratch, abrasion and impact resistant construction keeps the bowl performing through repeated dishwashing, pot loading and utensil contact in active residential kitchens.

Quartz Sink Details That Support Daily Work

• Made from 80% natural quartz crystals and pure acrylic resin, the sink offers a solid, stone-like feel that stands up to repeated loading of cookware and dishware in regular kitchen use.
• Heat resistant up to 535 F withstanding rapid temperature changes from hot and cold water, the bowl tolerates typical hot-pan placement and sink flushing without material failure under stated conditions.
• Durable quartz material is non-porous, preventing the spread of germs and bacteria so the interior surface cleans down to a hygienic finish during everyday washing and rinsing tasks.
• Extremely stain, scratch, abrasion and impact resistant construction holds its working appearance as pots, pans and metal utensils are moved, slid and set into the bowl during normal kitchen workflows.
• Rear drain location provides more storage room in your cabinet below, freeing space in the base cabinet for plumbing clearance and under-sink items around the back offset drain line.
• The 9 inch deep bowl provides plenty of room to accommodate cookware, allowing larger pots and baking pans to sit fully in the sink while filling, soaking or rinsing.

Installation Fit, Cabinet Size, And Drain Details

This Karran single bowl kitchen sink is designed for undermount installation into quartz, granite and solid surface countertops, so it integrates cleanly under rigid tops commonly used in higher-end kitchens. A minimum cabinet size of 27 inch sink base cabinet establishes the base width needed for proper undermount support and bowl clearance. The drain opening size of 3-1/2 inch matches standard kitchen drain dimensions, simplifying the connection of strainer bodies and typical kitchen drain fittings. The rear drain location shifts the waste outlet toward the back of the cabinet, which opens up a clearer area near the front for organizing under-sink items. Compatibility with most garbage disposals allows the sink to work with standard disposal units that match the 3-1/2 inch opening and rear-positioned outlet.

How This Karran QU-820-BI Sink Works In Kitchens

Where This Quartz Undermount Sink Performs Best

The Karran QU-820-BI sink is a quartz single bowl undermount unit sized at 24-3/8 inch wide by 19-1/8 inch deep, so it fits well where a compact yet full-depth kitchen sink is required. Being part of the quartz sinks class, it pairs naturally with quartz, granite and solid surface countertops by using the same rigid substrate for a flush undermount reveal. The bisque color tone comes from the quartz and acrylic blend, which supports light-colored kitchen schemes where the sink is expected to coordinate with neutral counters. Approximate weight of 29 lbs reflects a solid construction that provides stability once supported by the countertop and cabinet rails. Rear drain placement and the 9 inch deep bowl combine to create a working zone that keeps dish stacks and soak pans inside the sink footprint while preserving more open space in the base cabinet below.

Details That Support Reliable Use And Replacement

The manufacturer part number QU-820-BI and the reference to replacement for old WBSC part number KAQU671-BL help identify this specific bowl when matching to prior installations or specifying repeat work. All external dimensions are approximate to 1/4 inch, providing a realistic sizing tolerance that matters when cutting or verifying countertop openings and aligning the bowl with existing cabinetry. The drain opening size of 3-1/2 inch and compatibility with most garbage disposals mean the sink connects to standard kitchen drain and disposal hardware that share this opening dimension. Heat resistance up to 535 F, along with the ability to withstand rapid temperature changes from hot and cold water, supports long-term service where hot pots, boiling water dumps and cold rinses happen in sequence. The non-porous, extremely stain, scratch, abrasion and impact resistant quartz material supports repeat cleaning, scrubbing and dish handling without degrading the working surface in normal conditions.
