Karran 24-3/8"W x 19-1/8"D Quartz White Single Bowl Undermount Sink - QU-820-WH

Karran Quartz Undermount Sink For Busy Kitchens

Karran quartz undermount sink describes a 24-3/8 inch wide by 19-1/8 inch deep single bowl sink designed for undermount use in kitchen projects, so it suits installers working with compact sink base cabinets. The sink is made from 80% natural quartz crystals and pure acrylic resin, so it provides a dense, solid feel that supports daily use in a kitchen workspace. Its quartz material is non-porous, which stops liquids from soaking in and helps limit areas where germs and bacteria can develop on the sink surface. The quartz construction is heat resistant up to 535 F and can withstand rapid temperature changes from hot and cold water, so it handles hot pots and alternating water temperatures during normal kitchen tasks. This Karran sink is part of the quartz sinks product class, giving installers a specific match when coordinating with other quartz-based kitchen components.

Quartz Sink Details That Support Daily Use

• The 24-3/8 inch width and 19-1/8 inch depth define a compact single bowl footprint, so it works where counter space is limited but a functional work bowl is still required.
• The single bowl design creates one uninterrupted workspace, which simplifies handling larger cookware during washing and rinsing tasks without divider interference.
• The quartz material uses 80% natural quartz crystals with pure acrylic resin, creating a solid composite that stands up to routine contact with dishes and utensils.
• The durable quartz is described as extremely stain, scratch, abrasion and impact resistant, so the surface holds up against common kitchen impacts and cleaning routines.
• The non-porous quartz surface prevents the spread of germs and bacteria, supporting a cleaner, more hygienic sink area in everyday kitchen use.
• The heat resistance rating up to 535 F and tolerance for rapid temperature changes means the sink can take hot and cold water shifts during normal cooking workflows.

Undermount Installation And Cabinet Fit Details

This Karran quartz sink is designed for installation into quartz, granite and solid surface countertops, so it aligns with common hard-surface tops used in kitchen remodels and new builds. The undermount style lets the sink attach beneath the countertop, creating a flush transition that simplifies wiping debris straight off the counter into the bowl. The minimum cabinet size required is a 27 inch sink base cabinet, so installers can plan base cabinet layouts around this dimension when selecting or modifying casework. A rear drain location shifts the drain path toward the back of the cabinet, opening more usable storage space at the front for items such as trays or bins. The 9 inch deep bowl provides extra working depth, so it accommodates taller pots and stacking dishes without crowding the countertop edge.

How This Karran Quartz Sink Works In Practice

Single Bowl Quartz Sink In Kitchen Layouts

The Karran 24-3/8 inch wide by 19-1/8 inch deep quartz white single bowl undermount sink sits within the sinks and accessories category, so it fits directly into kitchen and bath cabinet projects handled by woodworking professionals. Its white quartz finish ties in visually with many quartz, granite and solid surface countertops, supporting cohesive designs when matching light or contrasting surfaces. This sink uses a rear drain location, which pushes plumbing toward the back and leaves more open floor area inside the base cabinet for storage or access to other components. The 9 inch deep bowl is sized to provide plenty of room to accommodate cookware, so tasks like soaking pans or staging dish racks stay inside the bowl rather than on the counter. The approximate weight of 29 lbs defines the mass an installer will handle when positioning the sink under the countertop cutout during installation.

Details That Support Fit, Flow, And Replacement

The sink is designed for installation into quartz, granite and solid surface countertops, so fabricators can cut a single undermount opening specification when working across these materials. The drain opening size is 3-1/2 inches, which is a common opening size that the manufacturer describes as compatible with most garbage disposals, so installers can coordinate disposal selection around that interface. All external dimensions are approximate to 1/4 inch, giving a defined tolerance range that fabricators can use when planning cutouts and clearances around the sink perimeter. The manufacturer part number QU-820-WH and the description QU QZ KITCHEN SINK,UMT SGL 24.37 WHITE specify it as a quartz undermount single bowl kitchen sink, so replacement or reordering stays traceable by part reference. This sink is also identified as a replacement for old WBSC part number KAQU671-BR, providing a direct link when updating older installations to the current Karran quartz model.
