This Gozney Roccbox vs Ooni Karu 12 comparison breaks down the key differences so you can decide with confidence.
The Gozney Roccbox and Ooni Karu 12 are two of the most popular high-performance portable pizza ovens on the market. Both reach 500°C, both produce excellent Neapolitan-style pizza, and both are built to a genuinely high standard. The differences come down to fuel flexibility, weight, and overall experience.
Quick Verdict
Buy the Gozney Roccbox if: you want a premium, ultra-portable gas oven with a thick stone and exceptional insulation, and you don’t need wood-firing capability.
Buy the Ooni Karu 12 if: you want the flexibility to cook on wood, charcoal or gas, and are comfortable with a slightly larger, heavier oven.

| Weight | Around 20kg | Around 12.5kg |
| Max temperature | 500°C | 500°C |
| Stone thickness | 30mm cordierite | 10mm cordierite |
| Preheat time | Around 25-30 minutes | Around 15 minutes |
Build Quality
The Roccbox is built to a higher specification than the Karu 12. Its stainless steel shell with silicone jacket is exceptionally well insulated – the exterior stays cool to the touch even at full temperature, which is an important safety feature. The 30mm cordierite stone is significantly thicker than the Karu 12’s 10mm stone, which means better heat retention and more even cooking across the base.
The Karu 12 is well-built for its price point and uses quality materials, but the difference in stone thickness is noticeable in practice. The Karu 12’s thinner stone can drop temperature more quickly between pizzas if you’re not actively managing the fire or flame.
Fuel Options
The Ooni Karu 12 is a genuine multi-fuel oven. Out of the box it runs on wood and charcoal; the optional Ooni gas burner (around £60) converts it to gas in seconds. This flexibility is the Karu 12’s strongest selling point – you get the romance and flavour of wood-firing when you want it, and the convenience of gas when you don’t.
The Roccbox runs on gas as standard. A wood burner attachment is available separately from Gozney, but it’s a less natural experience than the Karu 12 on wood – the Roccbox is fundamentally designed around gas. For pure gas performance, the Roccbox’s burner is excellent, producing an intense, wide flame that heats the cooking chamber evenly.
Weight and Portability
At around 20kg, the Roccbox is notably heavier than the Karu 12’s 12.5kg. The Roccbox is still considered portable, but the weight difference is meaningful if you’re planning to carry it to the park or put it away in a cupboard after each use. The Karu 12’s folding legs and lighter weight make it the more genuinely portable option.
Temperature and Cooking Performance
Both ovens reach 500°C. In practice, the Roccbox’s thicker stone holds temperature more consistently, which shows up most clearly when cooking several pizzas in a row. The Karu 12 requires more active management of the fire between pizzas to maintain stone temperature.
At peak temperature, both ovens cook a Neapolitan pizza in 60-90 seconds with regular turning. The results are comparable – blistered crust, leopard-spotted cornicione, and the slightly smoky base that comes from very high-heat cooking.
Price
The Roccbox is the more expensive oven, reflecting its premium build and heavier stone. The Karu 12 is significantly cheaper, though adding the gas burner closes the gap somewhat. Check current prices:
Which Should You Buy?
The Roccbox is the better oven in terms of build quality and heat retention. If you’re committed to gas cooking and want the most premium portable pizza oven experience available, it’s worth the extra money. The thick stone, exceptional insulation and professional-grade burner put it slightly ahead on pure performance.
The Ooni Karu 12 is the more versatile choice. The ability to cook on wood gives you an experience the Roccbox can’t fully replicate, and the lower price and lighter weight make it more accessible. For most buyers, the Karu 12 represents better overall value.
Also worth considering: if budget is flexible, the Ooni Karu 16 offers significantly more cooking capacity than either of these 12-inch ovens for not a great deal more money.
