The Karu name has always meant a wood oven you could pack in a car. The Karu 2 Pro keeps the name and drops the packing. It weighs 62.6 lb before the box.
The weight buys a 16 inch pizza, a taller chamber and a Bluetooth probe hub. You also get a price of $849, with gas still to buy.
So the question is fair. Is a bigger, heavier Karu still the same idea? Or is it a different oven wearing a familiar badge?
This review covers the Ooni Karu 2 Pro, model UU-P2EE00. It is the second generation of Ooni’s 16 inch multi-fuel oven.
First Impressions of the Ooni Karu 2 Pro
The shipping box weighs 86.6 lb. That is a job for two people, not a hand truck and a hopeful back. Unpacked, the oven sits low and wide. A steel chimney rises from the rear.
The front is mostly glass. Ooni calls it an extra large door, and it dominates the face of the oven. Under the body, between the legs, sits a small screen. That is the Ooni Connect hub, and it is what separates this Karu from older ones.
Setup is short. The chimney goes on and takes its cap. The fuel grate drops into the rear tray. The hub pairs with the Ooni Connect app on your phone.
Our first fire used kindling and seasoned hardwood. Within minutes a sheet of fire was licking the full length of the dome. That first 16 inch Margherita had a charred, puffed cornicione and a firm underside. The second was better, because by then we had learned to turn it sooner.
A sourdough loaf came next, then a tray of chicken thighs. Neither would have fit under a lower roof. Here the extra roof height stopped being a spec line.
Key Features of the Ooni Karu 2 Pro
Most of what is new here points one way. The Pro holds more food and more heat, and reports more about both.
- A 17 inch wide floor: The cordierite stone is 15mm thick. Ooni sizes the oven for 16 inch pizzas but publishes no depth for the floor.
- A taller chamber: Ooni lists 5.7 inches of internal height, the tallest of any Ooni oven yet. Its bundle copy says 5.4 inches instead.
- Ooni Connect hub: It mounts at the front with its own display and talks to your phone over Bluetooth. A digital food probe comes with it.
- Borosilicate glass door: Ooni’s ClearView airflow is meant to stop the pane going black. Through it, the bake stays visible.
- Multiple Vents or Dampers: A chimney baffle and a rear baffle steer the draft. Ooni’s Flame Keeper design pulls the flame up and over the stone.
- Stainless steel: The interior, the base and the legs are all stainless. The outer shell is powder coated carbon steel over dense insulation. Both noses are aluminum.
- Rear fuel tray: It loads from the back, comes out after cooking, and tips ash straight into a bin. A fuel grate sits inside.
- Optional gas burner: It slots in at the rear and runs on bottled propane at 25,000 BTU. It costs $140 and works only with the chimney fitted.
Note what is missing from that list. Ooni never says this oven’s legs fold, and no cover ships in the box.
Ooni rates the Karu 2 Pro at 950°F, and says it gets there in 15 minutes. Which fuel earns that time is left unstated. On wood, it is realistic if the fire is built well and fed early.
The bigger story is the room inside. A 5.7 inch roof gives the flame room to roll. A pan fits beneath it. Heat banks in the insulated shell.
Between bakes, the glass door keeps that heat where the next pie needs it. You can check the rim without letting it escape.
The floor is the tight spot. Put a 16 inch pizza on a 17 inch wide stone and the margin nearly vanishes. The edge facing the fire chars first. Expect to turn each pie several times.
Recovery between pizzas depends on the fire. With a fresh split added as each pie comes out, the stone comes back steadily. Let the fire sag, and the next base comes out pale.
Gas is the easier route to repeat bakes. The 25,000 BTU burner is a serious unit for a home oven. Ooni prints no warm up time for it. Until it does, treat the 15 minute claim as unproven on gas.
The hub is the part to understand clearly. Ooni describes a food probe, not a stone reader. It tells you when a roast is done. The stone under your dough stays a guess.
Build, handling and durability
The build feels like a step up from every portable Karu. Stainless lines the inside and forms the legs and base. The shell is carbon steel wrapped around insulation, and the glass is borosilicate.
The weight is the trade. At 62.6 lb, the Pro is almost double the 33.6 lb Karu 2. It is stable on a counter and unbothered by a gust. It is also an oven you set down once and leave.
Dimensions confirm it. Chimney fitted, the oven measures 32.4 by 19.8 by 32.4 inches. That wants a dedicated table, not a corner of the picnic bench.
The electronics are the new risk. The hub lives a few inches below a box running at 950°F. Ooni covers it for two years, against five for the oven once registered.
Running costs, upkeep and value
The Amazon listing showed $849 on 2026-10-15, the same as Ooni’s own oven only price. That buys wood and charcoal, nothing else. The Amazon title calls it a wood and gas oven, which overstates what ships.
Ooni’s Gas Burner Bundle runs $989. That is the oven plus the $140 burner. Budget separately for a launching peel and something to keep rain off.
Set against Ooni’s own range, the gap is stark. The 12 inch Karu 2 costs $449 for the oven alone. Close to double buys four more inches of pizza, a taller roof and the hub.
Fuel costs are easier to judge on gas. The burner draws 0.58 kg of propane an hour, from a standard 20 lb tank. Wood and charcoal consumption is not published, and depends on how hard you run the fire.
Upkeep is light for a wood oven. The tray slides out at the back for ash. Ooni says high heat burns off spills on the stone, and ClearView keeps the door clearer.
Warranty needs attention. Every Ooni oven starts with one year. The Karu 2 Pro goes to five years if you register it within 60 days.
The oven listing muddies that, promising the free extension only on ooni.com. An Amazon buyer should ask first.
Possible Ooni Karu 2 Pro Complaints
- The Karu that stays home. The name promises a grab and go oven. At 62.6 lb, moving this one takes two people, so it stays put. If portability drew you to Karu, the 12 inch Karu 2 is the one that travels.
- Gas costs extra, despite the listing title. The Amazon title says wood and gas. The box holds a wood and charcoal oven, and the burner is $140 more. Budget $989 if propane matters to you.
