Karran QT-721-BI-PK1 sink kit is a 34 inch wide by 22 inch deep quartz double 60/40 bowl top mount sink that gives a kitchen two separate working bowls in one cutout. The large and small bowls let installers set up separate zones for prep and cleanup in the same sink footprint, which keeps tasks organized on the job and in daily use. The quartz material is made from 80 percent natural quartz crystals and pure acrylic resin, so the bowls form a solid, consistent surface that stands up to regular kitchen work. The double bowl layout in a single top mount unit helps streamline countertop cutout work while still delivering bowl separation that fits real cooking and cleaning routines.
This Karran quartz sink is designed for installation as a top mount sink in any countertop material, so installers can drop it in from above and rest the rim on the finished surface, which simplifies setting the unit into laminate, stone, or solid surface jobs. The sink requires a minimum 36 inch sink base cabinet, aligning the unit with a common kitchen base width and making layout planning more straightforward when centering the cutout. A drain opening size of 3-1/2 inches matches standard kitchen drain fittings, which helps tie the bowls into typical plumbing components. The sink is pre-drilled with one faucet hole, so a single-hole faucet can be mounted directly, and additional holes are marked on the underside of the faucet deck to guide drilling if an installation calls for extra deck-mounted fixtures.
This Karran quartz double 60/40 bowl sink fits kitchen projects that call for a top mount installation into any countertop material, giving flexibility across remodels and new construction. The minimum cabinet size requirement of a 36 inch sink base cabinet positions the unit squarely in standard kitchen runs, which helps with centering the sink under a window or within a cooking zone. Rear drain locations in each bowl free up more open area in the base cabinet front section, so installers can run plumbing toward the back and leave space for storage or systems mounted near the front. The 9 inch deep bowls support sink-centered tasks that involve tall stock pots, baking sheets, or stacked dishes, since the added depth keeps work inside the basin.
The quartz material is heat resistant up to 535 F and can withstand rapid temperature changes from hot and cold water, so the sink surface handles typical kitchen temperature swings without disrupting daily sink use. The durable quartz construction is non-porous, preventing the spread of germs and bacteria, which supports hygienic cleaning routines on food prep and dishwashing days. The material is extremely stain, scratch, abrasion, and impact resistant, so the basin stands up to regular contact with cookware, utensils, and cleaning tools over time. The approximate weight of 40 lbs keeps the unit substantial yet manageable during handling, which helps when positioning the sink into the countertop cutout from above. The drain opening size of 3-1/2 inches is compatible with most garbage disposals, allowing installers to tie the sink bowls into disposal units that match standard kitchen plumbing layouts.
