What Makes a Grill Island Different from an Outdoor Kitchen?

A grill island is a streamlined outdoor cooking area, typically focused around a grill or smoker, and often designed as a standalone unit or compact cooking station. Outdoor kitchens, by contrast, usually feature multiple cooking appliances, extensive cabinetry, refrigeration, and larger countertops. Our modular approach blurs these lines, allowing you to easily create simple grill islands or expand them seamlessly into more extensive kitchen layouts, entirely tailored to your needs.

If I could give Cornerstone Rocks 10 stars, I’d give them 20. From ordering to delivery to support, Jake and Terry are consummate pros. The instructions were spot on, and when we did have a question, a quick call got us right back on track. My friend and I—two old guys—built a Unity C+ and Unity Z+ Deluxe in an L-shape in just two days. Friends are blown away by the results! The only disappointment? That the build was over—it was that rewarding.
