Karran QU-711-BI Undermount Sink For New Tops

Karran QU-711-BI undermount sink is a 32-1/2 inch wide by 19-1/2 inch deep quartz double 60/40 bowl unit designed for new kitchen countertops. The sink is manufactured from 80% crushed quartz plus 20% acrylic resin, creating a rigid, stone-like basin that supports everyday kitchen use. Its external bowl dimensions help planners layout base cabinets and clearances accurately. The internal large bowl measures 17-1/2 inches by 15-3/4 inches by 9 inches, giving extra room for larger pots or pan washing. The smaller 11-3/8 inch by 15-3/4 inch by 9 inch bowl provides a dedicated space for rinsing or prep work without tying up the main bowl. A 1-1/4 inch by 3/4 inch machined resin matrix rim supports a stable undermount bond to the countertop. The sink bowl surface has a matte finish, which presents a subdued appearance in bisque color while maintaining a consistent working surface.

Quartz Double Bowl Details That Support Workflows

• The 32-1/2 inch by 19-1/2 inch external dimensions define the footprint, helping installers size base cabinets and align the sink within the run.
• The 60/40 double bowl layout uses a larger and a smaller basin, letting users separate washing and rinsing or prep tasks in everyday kitchen work.
• The large bowl interior size of 17-1/2 inches by 15-3/4 inches by 9 inches accommodates bulkier items, reducing crowding while cleaning larger cookware.
• The smaller bowl interior of 11-3/8 inches by 15-3/4 inches by 9 inches offers a contained space for food prep or light cleanup without occupying the main basin.
• The 3-1/2 inch waste opening connects to standard 3-1/2 inch sink drains, simplifying drain component selection and rough-in planning.
• The matte finish on the sink bowl surface provides a low-sheen work area in bisque, supporting a more understated look in the finished kitchen.

Undermount Quartz Sink Installation And Fit Details

This Karran quartz double bowl undermount sink is designed for undermount installation only, which means it is secured to the underside of the countertop for a clean edge at the cutout. The sink can only be installed in new countertops, not in existing countertops with an existing sink cutout, aligning it with remodels that involve new tops or new construction. It may be undermounted to all stone products, so fabricators can plan for granite, quartz, or other stone-type materials. The 1-1/4 inch by 3/4 inch machined resin matrix rim provides a consistent bonding surface against the countertop underside. A 1/8 inch overhang is recommended, but the sink can also be flush installed, giving fabricators flexibility to follow the preferred reveal style for a particular project.

How This Quartz Double Bowl Sink Fits Kitchens

Where The Karran Quartz Double 60/40 Bowl Works

This Karran quartz double 60/40 bowl sink is part of the quartz sinks product class, placing it in kitchen layouts that call for a stone-composite basin. Its external bowl dimensions of 32-1/2 inches by 19-1/2 inches suit many standard-width kitchen base cabinets, helping designers integrate it into common cabinet runs. The undermount requirement pairs well with solid stone countertops, and the ability to undermount to all stone products supports use with engineered quartz, granite, or similar tops. The bisque color and matte finish on the sink bowl surface offer a neutral, muted look that can coordinate with a range of cabinet and countertop combinations. The 60/40 bowl split with one larger and one smaller basin serves kitchens where users want a primary wash side and a secondary prep or rinse side in the same sink footprint.

Details That Support Repeatable Countertop Fabrication

The sink is manufactured from 80% crushed quartz plus 20% acrylic resin, giving fabricators a consistent material structure around the 1-1/4 inch by 3/4 inch machined resin matrix rim for bonding. All external dimensions are approximate to 1/4 inch, guiding shops to treat the listed dimensions as layout references during templating and CNC programming. A 1/8 inch overhang is recommended for installation, which offers a clear reference when setting reveal expectations with clients and aligning the cut edge. This sink may be undermounted to all stone products, allowing stone shops to standardize mounting procedures across different stone countertop lines. Digital templates for CNC machines are available at www.karran.com, helping CNC-based shops integrate the exact cutout shape and mounting details into their digital workflow for repeatable processing.
