Karran QT-720-BL sink is a 34 inch wide by 22 inch deep drop-in double bowl kitchen sink that creates two equal work bowls, so installers can offer clients separate zones for prep and cleanup in one cutout. The 9 inch external depth gives both bowls useful working depth, which helps contain splashes during everyday use. Internal bowl dimensions of 14-3/8 inch by 17-1/4 inch by 9 inch and 14-3/8 inch by 16 inch by 9 inch define two distinct spaces, so fabricators can plan faucet and accessory locations around real working footprints. Being suitable for top mounting into any type of countertop gives flexibility across laminate, solid surface, stone, and other tops on a single model. The black quartz finish supports dark, modern kitchen designs where sink color needs to coordinate cleanly with surrounding materials.
The sink is suitable for top mounting into any type of countertop, so crews can use a straightforward drop-in cutout without specialized undermount hardware. As a top mount design, the rim sits on the counter, simplifying support across different substrates. All faucets must be sink mounted with this model, so layout planning focuses on drilling through the sink deck rather than the countertop, which can streamline faucet location on dense or brittle surfacing materials. The defined external dimensions of 34 inches by 22 inches by 9 inches allow shops to standardize cutout templates and estimate clearances around backsplashes and adjacent cabinets with predictable results.
The sink provides a double 50/50 bowl layout, so both sides offer comparable working space for flexible kitchen use. Internal dimensions of 14-3/8 inches by 17-1/4 inches by 9 inches on one side and 14-3/8 inches by 16 inches by 9 inches on the other define two substantial compartments for washing, rinsing, or soaking tasks. This equal-style configuration supports homeowners who want one side dedicated to dishes and the other to food prep without changing basin depth. The overall 34 inch width gives each bowl enough span for full-size cookware while still fitting typical kitchen cabinet runs. With a 22 inch depth front to back, installers can align the sink comfortably within standard countertop depths while maintaining room behind the bowl for faucet mounting on the sink deck.
The sink is made from natural granite, quartz, and premium acrylic resins, which creates a composite that brings stone hardness together with resin impact resistance for long-term bowl stability. Because the construction is scratch, chip, and heat resistant up to 530 degrees F, the sink handles normal hot-pan placement and utensil contact during daily kitchen work. The uniform color throughout the material means the black finish is not just a surface coating, so typical wear stays visually consistent during service life. The nonporous surface prevents bacteria buildup in the sink structure itself, which supports routine cleaning practices by not absorbing spills. A 25 years Limited Warranty against manufacturer's defects provides long-term product backing from Karran, giving trade professionals and owners confidence that the sink is supported over many years of installed use.
