Black Quartz Undermount Sink for a Two-Task Kitchen Workflow

The Karran Q-360 is a 60/40 double-bowl undermount kitchen sink in black quartz composite, sized for a 33-inch or wider base cabinet and designed to mount beneath laminate, solid surface, or granite countertops.

Key Features

• 60/40 bowl split gives a larger primary bowl and a dedicated smaller bowl for separate prep or rinse tasks.
• Black quartz composite construction with a dense, non-porous surface throughout.
• Undermount installation into laminate, solid surface, or granite countertops.
• IAPMO certified for verified plumbing product compliance.
• 3-1/2 inch drain openings in both bowls accept standard waste fittings.
• Requires a minimum 33-inch cabinet to fit the 32-1/2 by 21-inch footprint.

A Sink Built Around the Way Kitchens Actually Work

The 60/40 split is the workhorse configuration for a reason: a larger left bowl handles big pots, sheet pans, and soaking, while the right bowl stays available for rinsing produce or holding a colander without crossing tasks. If your kitchen workflow means the sink is doing two things at once, this configuration keeps both going without interference. The undermount install removes the rim from the picture entirely, so wiping the counter straight into either bowl is a one-motion task.

Black Quartz Composite That Holds Its Look

The sink is made from quartz composite with a black finish that runs through the material rather than sitting on top as a coating. The surface is non-porous, which means it does not absorb liquids or harbor food residue the way a textured or porous surface can, and cleanup stays straightforward. Black reads as intentional here rather than decorative: it works equally well anchoring a monochromatic kitchen or contrasting with light countertops where the exposed apron of the bowl adds visual weight under the counter edge.

Where This Sink Fits the Project

This is the right sink for a remodel or new-build kitchen where the designer or homeowner wants a matte black undermount that does not disappear into the background. It mounts beneath laminate, solid surface, or granite countertops, which covers most residential and commercial kitchen countertop materials. Cabinet shops and installers planning the rough-in should note the 33-inch minimum cabinet width requirement. The IAPMO certification makes it a straightforward spec for projects that require third-party plumbing-product compliance documentation. Both bowls share a 3-1/2 inch drain opening, a standard size that works with commonly available waste fittings.
