Karran QU-720-CN Quartz Double Bowl Use

Karran QU-720-CN undermount sink is a 33-1/2 inch wide by 20-1/2 inch deep quartz concrete double 50/50 bowl sink, so it fits common kitchen layouts where a centered, equal-bowl work area is needed. The sink is manufactured from 80 percent crushed quartz plus 20 percent acrylic resin, creating a dense quartz composite that supports routine kitchen work. External bowl depth of 9 inches provides working room for larger pots while still fitting typical cabinet spaces that match this footprint. Internal bowl dimensions of 14-3/8 inches by 17-1/4 inches by 9 inches and 14-3/8 inches by 16 inches by 9 inches divide the workspace into two equal-depth bowls, which helps separate prep and cleanup tasks. The sink bowl surface has a matte finish, giving a non-gloss work surface suited to everyday kitchen use.

Quartz Sink Details That Support Daily Work

• The external bowl dimensions of 33-1/2 inches by 20-1/2 inches by 9 inches define the cutout and cabinet space, helping plan cabinet sizing and countertop layout for this specific sink footprint.
• The internal bowl dimensions of 14-3/8 inches by 17-1/4 inches by 9 inches and 14-3/8 inches by 16 inches by 9 inches set usable bowl capacity, so installers and users know how much room is available for washing, rinsing, and stacking items.
• Manufactured from 80 percent crushed quartz plus 20 percent acrylic resin, the sink uses a quartz composite structure that supports a solid-feeling basin for repeated kitchen use.
• The 1-1/4 inch by 3/4 inch machined resin matrix rim creates a defined mounting edge, giving a uniform surface for undermount bonding beneath compatible countertops.
• A 3-1/2 inch waste opening matches standard drain sizing, simplifying drain component selection and helping the installer align plumbing with typical kitchen waste fittings.
• The sink bowl surface has a matte finish, providing a non-gloss working surface that supports consistent appearance under varied kitchen lighting.

Undermount Quartz Sink Installation Factors

This Karran quartz double bowl sink requires undermount installation, so it is mounted from below the countertop for a seamless transition at the rim. The sink may not be top mounted, which directs installation planning toward an underside-support method. It can only be installed in new countertops, not existing countertops with an existing sink cutout, so layout is set during new fabrication. The sink may be undermounted to all stone products, so it aligns with stone countertop fabrication workflows. A 1/8 inch overhang is recommended at the countertop edge, but the sink can also be flush installed, giving fabricators a defined range for edge detailing around the bowls.

Using This Quartz Double Bowl Sink In Projects

Where This Karran Quartz Sink Fits Best

This Karran quartz double bowl sink belongs in kitchen projects that specify a 33-1/2 inch by 20-1/2 inch undermount layout, because those external dimensions guide both cabinet selection and stone fabrication. Being part of the quartz sinks product class, it uses an 80 percent crushed quartz plus 20 percent acrylic resin construction that supports a solid basin feel in residential or light commercial kitchens that match its size. The concrete color presentation groups it with contemporary stone and quartz countertop designs that coordinate with similar tones. Equal 9 inch bowl depths, with internal footprints of 14-3/8 inches by 17-1/4 inches and 14-3/8 inches by 16 inches, serve kitchens needing two full-depth work zones, such as one bowl for soaking and one for rinsing.

Details That Support Consistent Installation Results

The 1-1/4 inch by 3/4 inch machined resin matrix rim on this sink gives fabricators a predictable bonding surface, which supports repeatable undermount attachment across multiple installations using similar adhesives. The requirement for undermount installation, with no top mount option, focuses installers on a single method, reducing variability in how the rim meets the underside of stone countertops. Being undermountable to all stone products keeps fabrication steps consistent for granite, quartz, or other stone materials that match its size. The 1/8 inch recommended overhang defines a small, precise reveal, while the option for a flush install allows variation in edge detail where design calls for it. A 3-1/2 inch waste opening uses standard kitchen drain sizing, which helps coordinate cutout placement with typical plumbing rough-ins. Digital templates for CNC machines are available at www.karran.com, so shops using CNC equipment can align sink cutouts and rim details directly to the manufacturer-provided geometry.
