Black Quartz Undermount Sink for a Bold Kitchen Install

This Karran single-bowl undermount sink brings a deep black quartz-composite basin to kitchens where the finish is meant to make a statement. It mounts beneath quartz, granite, or solid surface countertops and delivers a full 9 inches of bowl depth in a 32-1/2 inch footprint.

Key Features

• Matte black quartz composite construction gives the sink a consistent, through-body color that holds its look under daily use.
• Single deep bowl at 9 inches inside depth handles large pots, sheet pans, and full-size cutting boards without splitting workspace.
• Undermount installation into quartz, granite, or solid surface countertops for a clean, rimless counter edge.
• Minimum 36-inch cabinet width required for proper fit and clearance.
• 3-1/2 inch drain opening accepts standard kitchen drain assemblies.
• cUPC certified for plumbing code compliance across the U.S. and Canada.

One Basin Built for a Working Kitchen

A single bowl at this depth gives you unbroken workspace from wall to wall inside the sink. There is no divider to work around when you are washing a roasting pan, filling a tall stockpot, or washing items too large for a divided basin. The 30-inch interior bowl length and 16-3/4 inch interior width make it a practical choice for a primary kitchen sink where the cook handles volume and scale, not just a quick rinse. The 3-1/2 inch drain opening fits standard kitchen strainer assemblies without adapters.

Quartz Composite in Matte Black

The sink is made from quartz composite, a dense engineered material that holds color through the body rather than relying on a surface coating. In matte black, that means the finish does not depend on a layer that can chip or wear through to a different color beneath. The non-glossy surface also diffuses light, so water spots and fine scratches are less visible than they would be on a polished or high-gloss black surface. Quartz composite handles heat from a pan pulled directly off the stove and resists staining from everyday kitchen use.

Where This Sink Belongs

This sink is a natural fit for kitchens designed around black and dark-toned palettes, particularly where the hardware, appliances, or countertop veining already pull toward black or charcoal. It works well with waterfall quartz countertops, honed granite slabs, and solid surface in dark colorways because the undermount installation lets the countertop material read uninterrupted to the bowl edge. Because it requires a minimum 36-inch cabinet base and installation into a new countertop, it is best planned into a new build or a full kitchen remodel where the counter is being fabricated to spec. Designers specifying black sinks for a cohesive dark kitchen will find this SKU ships on pallets of 20, making it practical for multi-unit residential projects.
