Karran quartz undermount sink in model QU-820-BL is a 24-3/8 inch wide by 19-1/8 inch deep black single bowl that mounts below the countertop, creating a clean edge that simplifies wipe-down and helps installers deliver a seamless look. The sink is made from 80% natural quartz crystals and pure acrylic resin, so the material combines stone content with a stable binder that works well in everyday kitchen use. This quartz construction is described as durable and non-porous, so the bowl surface resists absorbing moisture in normal use, which supports hygiene expectations in residential kitchens. Heat safety up to 535 degrees F means the sink can handle hot water and typical cookware temperatures without material failure under stated conditions. The single bowl is 9 inches deep, so it provides meaningful working depth for soaking, rinsing, and handling larger cookware in one basin.
This Karran 24-3/8 inch by 19-1/8 inch undermount quartz sink is designed to sit beneath the countertop cutout, so installers can create a continuous counter-to-sink transition that supports efficient cleanup. The rear drain locations shift the plumbing toward the back of the cabinet, which opens more usable floor space in the front area of the base cabinet for storage plans. With a 9 inch deep bowl, the sink layout provides enough depth to manage stacking dishes or soaking items while keeping splashing more contained inside the basin. The non-porous quartz material and black finish work together as a single molded bowl, giving buyers a consistent appearance that matches the stated color and material across the entire sink interior.
The Karran QU-820-BL black single bowl undermount sink suits kitchen and bath cabinetry projects where a quartz sink from the quartz sinks product class is required. Its 24-3/8 inch width and 19-1/8 inch depth match layouts needing a compact footprint with a full-size working bowl. The 9 inch deep basin allows installers to specify this bowl in designs that call for generous washing depth without moving to a double-bowl configuration. Non-porous quartz construction that prohibits the spread of germs and bacteria supports use in food-prep and clean-up zones where hygiene is a design priority. Rear drain locations pair well with cabinet layouts that rely on clear front-to-back space for pull-out storage or larger cleaning supply containers under the sink base.
The combination of 80% natural quartz crystals and pure acrylic resin creates a quartz undermount sink structure that supports daily use where repeated loading and cleaning cycles are expected. Heat safety up to 535 degrees F and resistance to rapid temperature changes from hot and cold water help the bowl tolerate real-world faucet use without material failure under described conditions. The undermount configuration allows fabricators to polish the countertop edge over the 24-3/8 inch by 19-1/8 inch opening, giving users a smooth transition so debris can be wiped straight into the sink. Rear drain locations change where the trap and waste line sit, preserving more open floor area in the cabinet for storage. The 9 inch deep bowl gives vertical working space that helps when soaking baking pans, tall stock pots, or multiple dishes at once. As a quartz sink in black, this model also supports design schemes that call for a dark, uniform sink surface integrated into the countertop plan.
