A Black Quartz Undermount Sink Built for the Modern Kitchen

This Karran quartz undermount sink brings two equally sized bowls beneath the counter in a deep matte black finish, designed for new countertop installations in granite, quartz, or solid surface.

Key Features

• Equal 50/50 double bowl configuration with matched 14-1/4 by 16-3/4 inch interiors and 9-inch depth in each bowl.
• Matte black quartz composite body made from natural quartz and acrylic resin for a dense, consistent finish.
• Undermount installation into granite, quartz, or solid surface countertops — requires a 36-inch minimum cabinet width.
• 3-1/2 inch drain opening in each bowl for standard disposal and strainer fittings.
• cUPC and IAPMO certified for plumbing code compliance.

Two Equal Bowls, One Clean Surface

A 50/50 split means neither bowl gets shortchanged. Keep one side clear for prep and the other ready for soaking or rinsing, without having to work around a smaller secondary bowl. Because this sink mounts under the counter, the countertop surface runs directly to the bowl edge with no rim collecting water or debris. That flush transition is especially clean when the sink and counter share a dark palette — the black quartz disappears into the stone rather than sitting on top of it.

Quartz Composite in Matte Black

The sink body is a quartz composite — natural quartz blended with acrylic resin — finished here in black. The matte surface keeps the finish consistent even in a hard-working kitchen, where a polished or high-gloss basin would show water spots and light scratches more readily. The color runs through the composite rather than sitting as a surface coat, so minor scuffs do not expose a different layer beneath.

Planning the Right Installation

This sink is designed for new countertop fabrications in granite, quartz, or solid surface. It cannot be dropped into an existing countertop with a pre-cut sink opening, so it belongs in a remodel or new build where the counter is being fabricated to spec. A minimum cabinet width of 36 inches is required. The overall sink footprint is 32-3/8 inches side to side and 19-1/4 inches front to back — measure the cabinet and confirm those dimensions with your countertop fabricator before ordering. The black finish suits kitchens with dark countertops, two-tone cabinet schemes, or any design where a stainless or white sink would read as an interruption rather than a detail.
