Karran quartz undermount kitchen sink describes a 24-3/8 inch wide by 19-1/8 inch deep single bowl undermount sink made from 80% natural quartz crystals and pure acrylic resin, so installers get a rigid bowl that handles daily kitchen use. This Karran quartz sink is designed for installation into quartz, granite and solid surface countertops, giving fabricators a clear fit target for common hard surface jobs. Its quartz material is heat resistant up to 535 F, so the bowl tolerates exposure to hot pots or frequent hot water without softening. The sink can withstand rapid temperature changes from hot and cold water, which helps on sites where users alternate between hot rinses and cold fills. Durable quartz material is non-porous, preventing the spread of germs and bacteria, which matters in kitchens that need a hygienic, easy-to-wipe surface. The sink surface is extremely stain, scratch, abrasion and impact resistant, supporting a long service life under cookware and utensil contact.
This Karran quartz single bowl sink is designed for undermount installation beneath quartz, granite and solid surface countertops, so it fits the standard workflow of solid surface and stone shops. The 24-3/8 inch wide by 19-1/8 inch deep footprint aligns with a minimum 27 inch sink base cabinet, which helps layout planning when pairing sink bases with countertop slabs. A rear drain layout concentrates plumbing toward the back, giving extra room near the front of the cabinet for pull-out trays or other storage systems. With 9 inch deep bowls, the sink provides vertical capacity while still fitting in typical 27 inch sink base cabinets. External dimensions being approximate to 1/4 inch let installers allow for small variances when mounting clips and sealing the rim.
This quartz concrete single bowl sink works in kitchen layouts using quartz, granite or solid surface countertops because it is specifically designed for installation into those materials. The undermount configuration lets the countertop edge run clean to the bowl, which suits stone and solid surface fabrication practices focused on flush, easy-to-wipe edges. A minimum 27 inch sink base cabinet requirement sets clear use in standard base runs where that cabinet size is available. The 9 inch deep bowl offers ample room to accommodate cookware, so residential kitchens that handle oversize pots or baking sheets gain a practical wash zone without multiple basins. The rear drain location supports storage under the sink base, which benefits kitchens where organized under-sink space is important for cleaning products or pull-out bins.
The Karran QU-820-CN sink pairs 80% natural quartz crystals with pure acrylic resin, producing a non-porous structure that resists staining, which reduces call-backs related to surface discoloration. Non-porous quartz material also prevents the spread of germs and bacteria, supporting cleaner long-term use without needing special cleaning steps. Heat resistance up to 535 F helps prevent damage from hot cookware, protecting both the sink and adjacent countertop edge during normal kitchen operation. The sink can withstand rapid temperature changes from hot and cold water, so fabricators do not have to factor in thermal shock as a typical failure point during everyday use. Extremely scratch, abrasion and impact resistant quartz supports durability when customers frequently stack heavy pots into the bowl. External dimensions being approximate to 1/4 inch help installers compensate during cutout fabrication and mounting, lowering the chance of on-site adjustments. The approximate 29 lbs weight is light enough for one or two-person handling under a quartz or granite top, which keeps installation moving efficiently on finish days. Replacement for old WBSC part number KAQU671-BI lets shops swap in this model wherever that earlier part was specified, maintaining continuity in projects that reference the former number.
