A Black Top-Mount Sink Built for High-Contrast Kitchen Design

The Karran QT-811-BL is a 33-inch quartz composite kitchen sink in Black that drops into any countertop material from above, making it one of the most flexible sinks in the line for remodels and new builds alike. Its 60/40 double-bowl layout gives you one large working basin and one smaller companion for rinsing, food prep, or overflow.

Key Features

• Top-mount installation into any countertop material, including laminate, quartz, granite, solid surface, and wood.
• 60/40 double-bowl configuration with a larger left basin and a smaller right basin for separating tasks.
• Quartz composite construction in a Black finish with consistent color throughout the body.
• cUPC and IAPMO certified for compliance with North American plumbing standards.
• 3-1/2 inch drain opening in each bowl for standard basket strainer and disposal hardware.
• Minimum 33-inch cabinet width required for proper support and fit.

Two Bowls, One Dominant Basin

A 60/40 split means the left bowl carries the larger share of the sink's interior, giving you room for a full stack of dishes, a large stockpot, or a cutting board set over the basin. The right bowl stays accessible alongside it for rinsing produce, draining pasta, or keeping a drying rack out of the main workspace. For cooks who use the sink as a staging area through prep and cleanup, that size difference is more useful than two equal bowls fighting for the same tasks.

Quartz Composite in Black

This sink is built from quartz composite, an engineered material that combines crushed quartz with resin to produce a dense, matte-surfaced basin. The Black finish runs through the body of the material rather than sitting as a surface coating, so chips and scratches at the bowl walls don't expose a different color underneath. A matte black surface also reads well against both light and dark countertop colors, which is why it's a go-to finish in high-contrast kitchen palettes. The sink carries cUPC and IAPMO certification, confirming it meets North American plumbing code requirements.

Where This Sink Works

Top-mount installation is the practical choice when a kitchen remodel keeps the existing countertop in place. Because this sink drops in from above and rests on its rim, it works on any countertop material without the adhesive bonding, precise undermounting, or countertop fabrication that some other installation methods require. That makes it a strong fit for laminate and tile kitchens where undermounting isn't an option, and equally straightforward in granite or quartz kitchens where the homeowner or contractor wants a fast, clean install. Cabinet shops and contractors specifying for clients who want a statement black sink without a farmhouse cutout will find the top-mount approach keeps install scope predictable.
