Black Quartz Undermount Sink for a Bold Kitchen Design

The Karran Q-350 is a double equal-bowl undermount kitchen sink made from quartz composite and finished in Black, suited for kitchens where the countertop and sink are meant to be noticed together.

Key Features

• 50/50 equal double bowl splits the basin for simultaneous washing and rinsing or soaking and prep.
• Quartz composite construction made from 80% crushed quartz and acrylic resin for a dense, hard-wearing body.
• Matte Black finish runs consistent through the material, so chips and scratches stay less visible than on a coated surface.
• Undermount installation only into laminate, solid surface, or granite countertops.
• 3-1/2 inch drain opening accepts standard kitchen drain assemblies.
• cUPC and IAPMO certified for plumbing compliance in residential and commercial applications.

Two Equal Bowls, One Clean Counter Edge

The 50/50 split gives each bowl equal depth and width, so neither side feels cramped when you're running a full sink. One bowl handles soaking or a colander; the other stays clear for rinsing. Because this is an undermount, the countertop drops straight to the bowl rim with no visible lip or flange above the surface, making cleanup from counter to sink a single wipe.

The 8-1/2 inch bowl depth handles tall pots and sheet pans without splashing over the edge, and the overall 32-1/2 by 19 inch footprint fits into a cabinet opening of 33 inches or wider.

Quartz Composite in a True Matte Black

The Q-350 body is 80% crushed quartz bonded with acrylic resin. That makeup gives the sink the weight and hardness of stone without the porosity of natural stone, and the matte black surface does not show water spots the way a polished finish does. The color carries through the material rather than sitting as a topcoat, which means everyday kitchen wear stays less visible over time. In a laminate countertop the sink can be bonded seamlessly at the rim for a fully integrated look.

Where This Sink Fits Best

This is a sink for a kitchen where a Black finish is part of a deliberate palette, matched to black hardware, a dark countertop, or a matte fixture set. Designers specifying a monochromatic or high-contrast kitchen will find this easier to coordinate than a stainless or white option. It is also practical for cabinet shops and contractors building new kitchens where the countertop is being fabricated to spec, since the undermount profile requires the counter to be built around it. Because this sink is designed for new countertop installations, it is not suited for dropping into an existing cutout from a previous sink.
