Black Quartz Undermount Sink for a Bold, Hardworking Kitchen
The Karran QU-720 is a double equal bowl undermount kitchen sink in Black quartz composite, built for kitchens where a dark, design-forward finish needs to hold up to the demands of daily cooking and cleanup. Its 80% quartz and 20% acrylic resin construction delivers lasting durability in a color that reads as intentional in any contemporary or two-tone kitchen.
Key Features
• Black quartz composite construction blends 80% natural quartz crystals with 20% acrylic resin for a dense, hard-wearing bowl interior.
• Double equal bowl layout divides the sink into two symmetrical basins, keeping wash and rinse stations clearly separated.
• Undermount installation positions the sink below the countertop edge for a clean sightline and easy counter-to-bowl wiping.
• Highly scratch, stain, chip, and heat resistant surface holds its Black finish through years of everyday kitchen use.
• No faucet deck on this undermount model, so the faucet and any accessories mount through the countertop rather than the sink.
Where the Double Bowl Format Earns Its Keep
A double equal bowl configuration works best when two tasks need to happen at once. One side holds a soak or a cutting board rinse while the other stays clear for washing. For households that hand-wash dishes, the separation between wash water and rinse water is practical every single day. The symmetrical layout also suits kitchens where neither cook wants to claim one side as dominant prep space. At 33-1/2 inches across, the sink fits comfortably in a standard 36-inch sink base cabinet with clearance for the faucet drilling behind it in the countertop.
A Finish That Works as Hard as the Material
Black is the most unforgiving finish in a kitchen, which is exactly why material quality matters here. The quartz composite body is described by Karran as highly resistant to scratches, stains, chips, and heat, so the color stays consistent rather than dulling from abrasion or fading from the heat of a rinsed pot. The finish is integral to the material rather than applied on top, which means minor surface contact does not expose a lighter substrate underneath. This is an indoor sink intended for standard kitchen environments.
The Kitchen and the Buyer This Sink Fits
Cabinet shops and designers specifying a dark kitchen — black cabinetry, dark hardware, matte or smoked countertops — will find the Black quartz finish coordinates without competing. Homeowners renovating a contemporary kitchen who want a sink that reads as a design choice rather than a utility item will appreciate the consistency of color across the full bowl interior. Contractors working in solid surface or quartz countertop installations will mount this as a standard undermount, with the reveal and countertop material confirmed before cutting. The QU-720 is not a seamless series sink; it installs as a conventional undermount in quartz, granite, and solid surface countertops.
Frequently Asked Questions
Does this sink install the same way as a standard undermount, or does it need special fabrication?
The QU-720 is a conventional undermount sink. It attaches beneath the countertop using clips or adhesive appropriate to the countertop material, with the reveal direction and amount agreed with the customer before cutting. It does not use the seamless bevel-bit method associated with Karran's Q Series.
Where does the faucet mount on this sink?
This model has no faucet deck. The faucet, soap dispenser, and any other accessories mount through holes drilled in the countertop behind the sink.
Will the Black finish show water spots or residue more than a lighter color would?
Dark sinks do tend to show mineral deposits more visibly than lighter colors. Routine rinsing and drying after use keeps the finish looking its best. The quartz composite surface is non-porous, so residue wipes away rather than soaking in.
Is a drain, grid, or template included with this sink?
This SKU is a bare sink. Drains, bottom grids, and cutout templates are sold separately. Confirm the drain size and compatible grid model before ordering accessories.
What countertop materials work with the QU-720 undermount installation?
Karran documents the QU Series for undermounting in quartz, granite, and solid surface countertops using the standard undermount method. Laminate countertops are not an appropriate substrate for this series.
A Sink That Commits to the Design
The QU-720 in Black delivers a double bowl kitchen sink that looks deliberate from day one and stays that way, backed by quartz composite construction built to resist the everyday wear that shows up first on dark surfaces.
