How This Gray Undermount Kitchen Sink Handles Daily Tasks
Gray quartz surfaces excel in high-traffic kitchens where functionality meets style. The neutral tone provides visual continuity whether you're preparing morning coffee or hosting dinner parties, while the non-porous surface resists staining from red wine, tomato sauce, and other common culprits that plague lighter sinks. Unlike stainless steel options that show every water spot and fingerprint, the Q-350-GR maintains its appearance throughout the day with minimal attention.
Professional chefs appreciate the heat resistance that allows placing hot pans directly into the sink during intensive cooking sessions. The 530°F threshold exceeds most residential cooking temperatures, preventing the thermal shock damage common with lesser materials. Each equal bowl provides 14-1/8" of width, accommodating large roasting pans and oversized cookware that smaller sinks cannot handle.
Kitchen Designers Pick the Q-350 Gray Double Bowl Sink
Kitchen designers consistently recommend the Q-350 series because it combines the aesthetic appeal of natural stone with the practicality of engineered materials. The 80% quartz content surpasses many competitor products that use 60-70% ratios, providing superior scratch resistance and longevity. IAPMO certification ensures compliance with Uniform Plumbing Code, International Plumbing Code, and National Plumbing Code of Canada requirements, eliminating installation complications and warranty concerns. Professional installers prefer the seamless undermount design that creates clean lines with both laminate and solid surface countertops without visible mounting hardware.
Lifetime Performance Guarantee Protects Your Investment

This warranty protection extends to residential and commercial applications, demonstrating the manufacturer's confidence in product durability. Claims processing requires no warranty registration – your sink receives automatic coverage from installation date.
Professional installation ensures warranty compliance and optimal performance. Karran recommends certified plumber installation to meet local building codes and maintain warranty coverage. The warranty covers repair or replacement at the manufacturer's discretion, with up to $150 installation credit for replacement units. This protection excludes damage from accidents, physical abuse, excessive heat beyond specifications, or improper maintenance.
Your Q-350 Gray Undermount Kitchen Sink Questions Answered
Q: How does gray quartz compare to stainless steel for daily maintenance?
A: Gray quartz requires only soap and water cleaning, while stainless steel needs specialized products to prevent water spots and scratches. Gray naturally hides mineral deposits that show prominently on stainless surfaces.
Q: Can I install this sink myself or do I need professional help?
A: Professional installation by a certified plumber is recommended for warranty compliance and proper sealing. Undermount installation requires precise countertop cutting and secure mounting clips.
Q: Will the gray color show scratches or wear over time?
A: The uniform gray color extends throughout the material thickness, making minor scratches virtually invisible. Quartz hardness prevents most kitchen utensil damage.
Q: Is this sink compatible with garbage disposals?
A: Yes, the 3-1/2" drain opening accommodates standard garbage disposal units with proper mounting hardware.
Q: How do I remove stubborn stains from quartz surfaces?
A: For normal stains, use soap and water. For stubborn stains, apply a 1:15 bleach-to-water solution for one hour, then rinse thoroughly.

A: The Q-350 installs seamlessly in granite, quartz, solid surface, and laminate countertops using appropriate mounting techniques.

A: Gray serves as a neutral bridge color that works with both warm wood tones and cool contemporary palettes, making it ideal for transitional design styles.
