The Karran QAR-750 in Concrete: Industrial Style and Durability
Homeowners who admire the cool, urban look of polished cement-and need a sink that works as hard as they do-will appreciate the Karran QAR-750 in Concrete. Its double equal bowls (34" × 21.25" × 9") offer generous capacity for prep, wash, and rinse tasks, while the retrofit apron-front design slides neatly into any standard 36" cabinet. The neutral concrete shade pairs effortlessly with stainless appliances, reclaimed wood shelving, or bold cabinet colors, giving designers wide creative latitude. Behind the style lies a quartz composite body that shrugs off 535°F heat, relentless scrubbing, and daily dye-laden messes. From loft kitchens to family hubs, this sink balances industrial appeal with the rugged performance that modern cooks demand.
How the Karran QAR-750 Double Bowl Kitchen Sink Outperforms Other Sinks
- 535°F Heat Resistance – Place cast-iron pans straight from the oven without fear of blistering or discoloration.
- Industrial Concrete Color – Neutral gray conceals scuffs and water marks 45% better than glossy white fireclay.
- 70% Noise Dampening – Quartz composite absorbs vibration, so clattering dishes sound 40 dB quieter than in thin stainless basins.
- Scratch-Defying Finish – Rated “Excellent” in ANSI abrasion tests; resist knife nicks and metal racks that mar softer materials.
- Non-Porous Hygiene – Blocks 98% of bacteria penetration, keeping odors at bay between clean-ups.
- Retrofit Installation – Shorter 6" apron fits existing 36" cabinets, saving up to $900 in carpentry changes.
- UV-Stabilized Pigments – Maintains consistent gray tone despite direct window exposure or under-cabinet lighting.
- Rear Drain Placement – Frees valuable space for recycling bins or an RO system in the base cabinet.
- Included Grid & Strainer – Stainless steel grid shields the basin floor; 3.5" basket strainer speeds debris removal.

Made for Heavy-Duty Days in Active Kitchens
Concrete Strength for Busy Households
Nine-inch-deep bowls swallow baking sheets and lobster pots with room to spare. The 50/50 split lets you soak casserole dishes on one side while hand-washing produce on the other. Thanks to the sink’s rear drains, plumbing connects closer to the wall, opening cabinet real estate for cleaners or a pull-out trash can. For families that meal-prep on Sundays, the scratch-defying surface tolerates trays of roasted vegetables, sizzling skillets, and an avalanche of utensils without losing its matte character.
Why Professionals Choose the Karran QAR-750 Non-Porous Quartz Sink
Contractors praise its retrofit apron-proof that farmhouse flair needn’t require a custom base. Compared with leading stainless competitors, installers report 35% faster mounting because the quartz composite’s molded lip seats snugly with minimal shimming. Designers favor the industrial gray palette, knowing it complements both marble veining and butcher-block warmth. Restaurateurs appreciate the sink’s ability to mute clatter during lunch rush, thanks to the dense quartz body that dampens vibrations better than padded steel.

Questions About the Karran QAR-750 Concrete? We’ve Got Answers
Q: Will the gray finish fade over time?
A: No. UV-stable pigments resist color shift even under direct skylights.
Q: Can I install a garbage disposal?
A: Yes. The 3.5" drain opening accepts most standard disposal flanges.
Q: How do I clean stubborn marks?
A: Use a nylon brush with baking soda paste, then rinse. Monthly Luster Pro Oil adds extra protection.

A: Never. The non-porous quartz composite is naturally waterproof.

A: A 36" base cabinet provides adequate support and clearance.
Q: Are undermount clips included?
A: Yes. Clips ship with the sink; seam adhesive is sold separately.
Q: Can boiling pasta water crack the basin?
A: No. The material withstands sudden hot-to-cold thermal shocks without stress fractures.
Q: What is the weight of the sink?
A: Approximately 52 lb-35% lighter than poured concrete models, easing installation.
Q: Does the grid scratch the surface?
A: The rubber-coated feet prevent metal-to-quartz contact.
