Karran 31-3/4"W x 19-3/4"D Quartz Black Single Bowl Undermount Sink Kit - QU-670-BL-PK1

Karran QU-670-BL-PK1 Sink For Busy Kitchens

Karran QU-670-BL-PK1 sink is a 31-3/4 inch wide by 19-3/4 inch deep single bowl quartz undermount unit that provides a generous work area, helping installers and users handle large pots and everyday prep in one continuous basin. As part of Karran's quartz sinks line, it is made from 80% natural quartz crystals and pure acrylic resin, so the bowl combines stone-like rigidity with a stable, uniform structure that suits repeat installations. The quartz black color delivers a deep, rich tone that ties into dark or contrasting countertop designs, while UV stabilization keeps that color looking consistent over decades of use under normal kitchen lighting. The 9 inch deep bowl creates extra vertical clearance, giving more room to stack cookware and reducing splash during heavy sink use.

Quartz Sink Details That Support Daily Use

• Being made from 80% natural quartz crystals and pure acrylic resin creates a dense, solid surface that stands up to regular kitchen tasks, which is useful on projects where the sink sees constant loading and impact from cookware.
• The quartz black material uses natural quartz and pure acrylic resins to provide deep and rich color, so designers can rely on a uniform black tone that supports consistent visual results across multiple installations.
• UV stabilization in the quartz construction keeps the color looking like new for decades, which matters in kitchens with strong ambient light where fading would otherwise cause callbacks or appearance issues.
• The durable quartz material is completely non-porous, preventing the spread of germs and bacteria, which supports hygienic food prep zones in residential kitchens and simplifies client explanations about cleanliness.
• Smooth, non-porous material means food residue will not stick or stain the surface, so cleaning becomes a quick wipe-down task and reduces long-term staining concerns in high-use kitchens.
• Daily cleaning is simple with just a cloth and soapy water, which reduces the need for special cleaners and supports straightforward maintenance instructions after installation.

Undermount Quartz Sink Fit And Installation Use

This quartz black single bowl unit is designed for installation under solid surface, granite, and quartz countertops, so fabricators can integrate it cleanly into common premium kitchen tops. The undermount design lets water and debris be pushed straight from the countertop into the bowl, which streamlines cleanup on islands and long runs. A minimum cabinet size of 36 inch base cabinet is required, giving installers a clear sizing reference when planning layouts and checking cabinet runs. The rear drain location leaves more room in the cabinet below, which helps route waste lines and position additional under-sink components in tight bases. An approximate weight of 31 lbs keeps the sink substantial yet manageable during positioning, templating, and mounting.

How This Quartz Black Undermount Sink Performs

Where This Karran Quartz Sink Works Best

This Karran 31-3/4 inch wide by 19-3/4 inch deep single bowl quartz undermount sink is built for kitchens using solid surface, granite, or quartz countertops, so it suits mid to upper tier residential projects. The 9 inch deep bowl provides enough space for large cookware and baking sheets, which helps in meal-prep heavy homes that load the sink with oversized items. With its rear drain location, the sink shifts plumbing toward the back, opening more room below the bowl for storage or additional components such as filtration housings. Heat safety up to 535 degrees F allows the quartz material to withstand rapid changes in temperature from hot and cold water, which supports everyday kitchen behavior when users move boiling pots or run alternating water temperatures. The natural quartz and pure acrylic resin build gives the sink deep and rich color, so modern black or mixed-material kitchens gain a strong visual anchor at the wet zone.

Details That Support Consistent Results And Workflow

The durable, completely non-porous quartz construction prevents the spread of germs and bacteria, which gives installers a clear hygiene benefit to present when specifying this sink in busy family kitchens. Because the smooth, non-porous surface resists food residue sticking and staining, daily cleanup is reduced to a quick rinse and wipe, supporting clients who want low-maintenance work areas. UV stabilization keeps the black quartz color looking like new for decades, which matters when aligning the sink with dark faucets or hardware and expecting long-term color coordination. The rear drain location leaves more room in the cabinet below, improving workflow for plumbers who need space for traps and additional lines. Heat safety up to 535 degrees F protects against thermal shock from hot and cold water changes, which reduces risk during normal use. Designed for undermount installation under solid surface, granite, and quartz countertops, the sink integrates flush with those materials, delivering a clean transition that fabricators can repeat across multiple kitchens using the same model.
