Bold Black and Built to Fit a 33-Inch Base Cabinet

The Karran Q-350-BL is an equal double-bowl undermount kitchen sink finished in black quartz composite, sized to drop beneath a 33-inch or wider base cabinet. Its two matched bowls and flush-under-counter install make it a natural fit for kitchens where a strong color statement meets practical layout.

Key Features

• Matte black quartz composite construction delivers a consistent, through-body color that holds its look against daily use.
• Equal 50/50 double bowl splits the sink evenly so one side can soak while the other stays clear for rinsing or prep.
• Undermount installation into laminate, solid surface, or granite countertops keeps the counter edge clean and uninterrupted.
• Minimum 33-inch base cabinet required, with a 32-1/2-inch overall width and 19-inch front-to-back depth.
• cUPC and IAPMO certified for North American plumbing code compliance.
• 3-1/2-inch drain opening on each bowl accepts standard waste fittings.

Two Equal Bowls, One Seamless Counter Edge

A 50/50 split means both bowls carry the same 14-1/4-inch length and 8-1/2-inch depth, so there is no smaller side to work around. One bowl handles a soaking pot while the other stays free for rinsing vegetables or draining pasta, and the undermount profile keeps the countertop surface running straight to the bowl without a rim to trap debris. For kitchens where workflow and visual cleanliness matter equally, the equal-bowl layout earns its place.

Black Quartz That Anchors the Kitchen

The matte black finish is built into the quartz composite itself rather than applied as a surface coating, so chips and scratches do not reveal a different color underneath. Quartz composite is dense and non-porous, which means food residue and liquids stay on the surface where they are easy to wipe away. The color reads as a grounding anchor in a light kitchen or as a continuous tone in a darker scheme, and it coordinates naturally with black pulls, matte hardware, and dark stone counters.

The Right Kitchen for This Sink

This sink is the right call for a new kitchen build or a countertop replacement where the designer or homeowner wants the sink to contribute to the color palette rather than disappear into it. Because it is an undermount, it is designed for new countertop fabrication and is not a drop-in replacement for an existing cutout. It bonds cleanly into laminate, solid surface, or granite. Cabinet shops and installers specifying for a client who has chosen black or two-tone hardware will find it coordinates across Karran's line, which offers this model in multiple finishes.
