Modular Fireplaces
Stone Age Manufacturing's modular fireplaces use reinforced concrete with steel and fiber reinforcement for superior durability. Designed to meet UL-127 and ULC-S610 safety standards, these units offer strong drafting performance to minimize smoke spillage. Available in five series with 41 configurations, they suit indoor and outdoor applications while maintaining structural integrity across climates.
Wood-Fired Ovens
Our wood-fired pizza ovens and smokers combine traditional masonry techniques with modern engineering. Constructed from heat-tolerant concrete, these kits deliver restaurant-quality performance at a fraction of imported oven costs. The range includes four dedicated ovens, three combo units, and a barbecue smoker designed for lifelong durability and flavor-enhancing wood cooking.
Outdoor Kitchen Islands
The patented Cabinet Component System features lightweight, fiber-reinforced concrete panels with galvanized steel brackets. This modular approach allows infinite layout configurations while maintaining structural strength. Kits assemble in minutes, accommodate any appliance brand, and accept all masonry finishes for seamless integration with existing outdoor spaces.
Fire Pits
Stone Age Manufacturing fire pits use the same reinforced concrete formulation as our fireplaces, with integral feet for mobility and clearance. Available in four models, these units offer spacious fireboxes that assemble quickly. Convertible for gas operation, they balance durability with flexibility for casual outdoor settings or permanent installations.
Masonry Accessories
Complementary accessories enhance functionality and aesthetics across all product lines. Firebox extensions, chimney caps, and thermal blankets improve performance, while backsplash kits and radiused components enable custom finishes. Ready-mix solutions and specialized tools support proper installation for both professionals and DIY builders.
