Real Stories, Real Outdoor Kitchens

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.
