Karran Quartz Undermount Sink For Two-Station Kitchen Workflows
The Karran QA-760 is a large/small bowl quartz composite undermount kitchen sink in Concrete, offering a practical two-basin layout for kitchens where prep and cleanup share the same space. Its 34-inch footprint and 9-inch bowl depth make it a capable primary sink for demanding everyday use.
Key Features
• Quartz composite construction — 80% natural quartz crystals and 20% acrylic resin deliver a surface that is highly resistant to scratches, stains, chips, and heat.
• Large/small bowl configuration — an offset two-basin layout dedicates the larger bowl to washing and the smaller bowl to prep, disposal, or draining.
• Undermount installation — the flat mounting rim sits beneath the countertop for a clean counter edge that wipes down without catching debris at the sink border.
• Concrete finish — a warm, neutral tone that coordinates with grey, white, and mixed-material countertop palettes.
• 9-inch bowl depth — accommodates large pots and sheet pans without forcing awkward angles at the faucet.
Built for Separate-Task Kitchens
A large/small bowl layout works best when the kitchen handles more than one job at a time. The larger basin takes on the heavy lifting — soaking, scrubbing, and rinsing full-size cookware — while the smaller bowl stays free for a separate task: draining pasta, staging produce, or housing a disposal. That division keeps the workflow moving without waiting for one bowl to clear before the other can be used. The 9-inch depth means large stockpots and roasting pans sit far enough below the rim to fill and rinse without splash-over.
Quartz Composite in a Concrete Tone
Karran's quartz composite formula — 80% natural quartz, 20% acrylic resin — produces a dense, non-metallic bowl that resists the wear patterns common to kitchen sinks: scoring from utensils and cookware, staining from coffee and acidic foods, chipping at the bowl edge, and heat from pots pulled directly off the burner. The Concrete color runs through the full thickness of the material, so minor surface wear does not expose a different tone underneath. It pairs well with natural stone slabs, engineered quartz countertops, and poured-concrete surfaces, and its neutral grey sits between warm and cool without pulling hard toward either.
Where This Sink Fits Best
This sink is a good fit for kitchen renovations and new builds where the countertop is quartz, granite, or solid surface and the design calls for an undermount installation. Cabinet shops and designers specifying a kitchen with a 36-inch or larger sink base will find the two-bowl layout easy to work into a standard run. Homeowners who hand-wash cookware regularly, or who want a dedicated disposal side, will get direct use out of the offset bowl split. The Concrete finish is particularly well-suited to contemporary, transitional, and industrial-style kitchens where greys, whites, and natural wood tones are already in the palette.
Frequently Asked Questions
What countertop materials work with this sink?
The QA-760 is an undermount sink designed for quartz, granite, and solid surface countertops, where the countertop edge can be finished and the sink attaches with clips or fasteners from below. It is not the right choice for laminate — if you need a quartz sink for a laminate or solid surface top with no visible seam, look at Karran's Q Series instead.
Does the sink come with a drain, grid, or mounting hardware?
Included components should be verified at checkout. Karran Q Series spec sheets note that templates and clips are not included with standard undermount models. A drain assembly and bottom grid are typically purchased separately for this series — confirm the pack suffix on the SKU you order.
Which bowl is the large bowl, and which is the small?
The SAP model description notes a left-hand large bowl and right-hand small bowl orientation as configured. Verify the exact layout with the spec sheet before installation to confirm it matches your cabinet run and faucet plan.
Is the Concrete finish resistant to discoloration over time?
Karran describes its quartz composite as highly stain resistant. The Concrete color runs through the body of the material, so it does not rely on a surface coating that could wear away. Routine cleaning with a non-abrasive cleaner is all that is needed to maintain the appearance.
Can this sink be installed by a homeowner, or does it need a professional?
Undermount sinks in stone and quartz countertops are generally installed by a countertop fabricator as part of the countertop installation. The countertop needs to be cut, finished, and the sink attached from below — a process that typically requires the fabricator to have the physical sink on-site before cutting.
The Right Bowl Split for a Working Kitchen
The QA-760 brings a practical two-station setup to kitchens that need both a main wash basin and a dedicated prep or disposal side, finished in a Concrete tone that holds its own in modern and transitional designs.
