Karran QU-721-BL-PK1 Sink For Busy Kitchens

Karran QU-721-BL-PK1 sink is a 33-1/2 inch wide by 20-5/8 inch deep quartz black double 60/40 bowl undermount sink designed for installation into granite, quartz and solid surface countertops, so it suits common premium kitchen surfaces. Made from 80% natural quartz crystals and pure acrylic resin, the sink delivers a dense, engineered stone construction that supports long-term use in active kitchens. The durable quartz material is non-porous, preventing the spread of germs and bacteria, which helps keep the sink area more sanitary during food prep and cleanup. The double 60/40 bowl layout gives two working zones, supporting separate washing and rinsing workflows. As part of Karrans quartz sinks product class, this model provides a solid, consistent surface that integrates cleanly with undermount installations and supports a professional finished look.

Key Quartz Black Double Bowl Advantages

• The 33-1/2 inch width and 20-5/8 inch depth size the sink to handle larger cookware while staying within typical residential cabinet runs, helping installers fit it into standard layouts.
• The double 60/40 bowl configuration divides the basin into a larger and smaller work area, allowing users to handle washing and rinsing or prep and cleanup tasks simultaneously without crowding.
• The quartz black finish pairs with granite, quartz and solid surface countertops, giving designers and installers a coordinated look that blends the sink into darker or contrasting tops.
• The durable quartz material is extremely stain, scratch, abrasion and impact resistant, so the bowl surfaces stand up to regular pot, pan and utensil contact in everyday kitchen use.
• The non-porous quartz construction prevents the spread of germs and bacteria on the sink surface, supporting a cleaner working zone around food preparation and dishwashing.
• The approximate 36 pound weight reflects a substantial, rigid build, which helps the sink remain stable once undermounted and supported in a correctly sized cabinet.

Installation Details For Undermount Fit

This Karran quartz undermount sink is designed for installation into granite, quartz and solid surface countertops, so fabricators can cut and polish openings in those materials with predictable undermount support. The minimum cabinet size required is a 36 inch sink base cabinet, giving planners a clear lower-cabinet specification when laying out runs. Rear drain locations provide more storage room in the cabinet below, because plumbing can route toward the back instead of occupying the center area. The sink uses a 3-1/2 inch drain opening size, aligning with common kitchen drain and disposal fittings for straightforward connection. With a weight of approximately 36 pounds, the undermount installation benefits from solid countertop support and proper bracing during setting.

Using This Quartz Black Double Bowl Sink

Where This Karran Quartz Undermount Sink Fits

This quartz black double 60/40 bowl undermount sink is designed for kitchens using granite, quartz and solid surface countertops, so it fits well in higher-end residential or light commercial settings using those materials. The required 36 inch sink base cabinet makes it a natural choice in standard-width base runs, avoiding oversize cabinetry. Rear drain locations open more storage room in the cabinet interior, helping designers keep space for cleaning supplies or pull-out organizers. The 9 inch deep bowls provide plenty of room to accommodate cookware, so larger pots, pans and baking sheets sit lower in the basin rather than crowding the counter. With two bowl sizes, it suits layouts where one side handles heavy scrubbing while the other holds rinsing or soaking tasks.

Details That Support Daily Workflow And Durability

Made from 80% natural quartz crystals and pure acrylic resin, this sink uses an engineered composition that provides consistent density across the bowl surfaces, supporting everyday impact from dishes and utensils. The durable quartz material is extremely stain, scratch, abrasion and impact resistant, so repeated contact from metal cookware is less likely to affect appearance during regular kitchen routines. Heat resistance up to 535 degrees Fahrenheit allows the sink to withstand rapid temperature changes from cold and hot water, helping it tolerate typical shifts between hot rinses and cold fills without stress cracking. The non-porous quartz surface prevents the spread of germs and bacteria, simplifying cleanup because residues stay on the surface rather than absorbing into the material. Rear drain placement also shifts the working area forward, giving users a flatter central base for stacking dishes while plumbing stays toward the back.
