A Black Quartz Drop-In Sink for a Bold, Low-Maintenance Kitchen

This Karran QT-670-BL is a single-bowl top-mount quartz sink in a deep, matte black finish that installs into any countertop material. At 33 inches wide with a 9-inch bowl depth, it is sized for a standard kitchen workstation and anchored by cUPC and IAPMO certification.

Key Features

• Top-mount installation into any countertop material, including laminate, solid surface, quartz, granite, and tile.
• Single bowl at 29 inches long and 16-3/8 inches wide, with a 9-inch depth that handles large pots and sheet pans without crowding.
• Matte black quartz composite body with color consistent through the material.
• 3-1/2 inch drain opening compatible with standard kitchen drain fittings.
• cUPC and IAPMO certified, meeting plumbing code requirements across the US and Canada.
• Minimum 33-inch cabinet width required for proper support and fit.

One Deep Bowl for Everyday Kitchen Work

A single-bowl sink clears the divider out of the way, giving an unbroken basin that handles baking sheets, stockpots, and roasting pans that a divided bowl cannot. The 9-inch depth keeps water from splashing over the rim during high-volume tasks and leaves room to submerge larger items fully. For a kitchen where the sink sees real daily use, the single-bowl layout earns its keep quickly.

Black Quartz Composite That Holds Its Look

The sink body is a quartz composite, the same dense engineered material used across the Karran QT line. The matte black finish runs through the material rather than sitting only on the surface, so chips and scratches do not expose a contrasting color underneath. Black works as a deliberate design choice in contemporary kitchens and in darker or high-contrast palettes where a white or bisque sink would compete with the color scheme rather than anchor it. The top-mount rim seats against the counter and seals on installation, and because it fits any countertop material, it is not limited to the hard-stone counters that an undermount requires.

Where This Sink Fits Best

This sink suits a remodel or a new build where the countertop is already in place or where a drop-in install is simpler than cutting for an undermount. It is the right call in kitchens with laminate countertops, where undermounting is not an option, and in tile, solid surface, or quartz counters where a top-mount is simply the preferred approach. Cabinet shops specifying or fabricating kitchen packages can use this sink across a wide range of counter materials without steering around compatibility constraints. Homeowners doing their own install will find the top-mount straightforward: drop the sink into the cutout, secure the clips from below, and connect the drain.
