Solo Stove Pi Prime Gas Pizza Oven: Specs, Sizes and Who It Suits

The Solo Stove Pi Prime Gas Pizza Oven is a gas oven in the 12 inch class with a 13 in round cooking surface. Everything below is drawn from published manufacturer specifications and verified owner reports. Where a figure is not something we can stand behind, the row is left out rather than filled with a plausible guess.

A demi-dome chamber built purely around propane, with no compromises made to accommodate a second fuel. That shape is the argument: it pushes heat back down onto the stone rather than letting it stream out of the opening, which is why the Pi Prime holds its floor better than its weight suggests. No fuel swapping, no fire management, no ash. For a cook who is certain they will never burn wood, this is a cleaner design than any multi-fuel oven.

What are the Solo Stove Pi Prime specifications?

What is it good at?

• A chamber shape optimised for one fuel rather than compromised for two.
• Wide mouth for a 12 inch oven, so launching is less tight than the class average.
• Stainless construction and a genuinely simple assembly.
• Fifteen minute preheat with nothing to tend.

What are its real limitations?

• Gas only, permanently. There is no wood path from here.
• No door, so the mouth bleeds heat and the front of the stone runs cooler.
• Twelve inch class, so the practical pizza is around 11 inches.

Who should not buy it: Skip it if there is any chance you will want to cook with wood. Multi-fuel ovens exist precisely because that decision changes for a lot of people after the first season.

How does the fuel type change how you use it?

Propane through the supplied regulator. Because the burner runs continuously rather than in bursts, temperature holds very steadily, which is the practical benefit of the demi-dome shape over an open box.

Gas is the low-effort option and it is the right default for most people. The burner holds a temperature without your attention, there is no ash, and the oven is usable on a weeknight when tending a fire for half an hour is not appealing. What you give up is the small amount of aroma a wood fire contributes, which at a 90 second bake time is genuinely marginal, and the pleasure of managing a fire, which is not marginal at all to the people who care about it. The full comparison is on gas versus wood fired.

What dough suits this oven?

A steady 900F floor suits a straightforward Neapolitan dough at 60 to 62 percent hydration and 250 g balls. If you are coming from a home oven, resist the urge to keep using bread flour here: it browns too fast at this temperature.

At a floor temperature of 850F or above, a 12 inch pizza bakes in 60 to 90 seconds and has to be turned three or four times, because one edge scorches in roughly 20 seconds.

Work the exact weights out rather than scaling a recipe by eye. The hydration calculator turns a ball count and a hydration percentage into flour, water, salt and yeast to a tenth of a gram, and the ball weight calculator sizes the balls for the pizza this oven can actually cook. Dough weight scales with area, not diameter, so a 15 inch pizza needs 78 percent more dough than a 12 inch, not 25 percent more.

What does it need alongside it?

A turning peel is required rather than optional at this temperature. A cover matters too, since the open mouth means rain reaches the stone directly.

Three things are close to mandatory for any oven in this class. An infrared thermometer , because the floor temperature is the number that decides the bake and no built-in gauge measures it reliably. A turning peel , because a pizza has to be spun during the bake and a launching peel cannot do it. And a digital scale , because every dough figure on this site is a weight and none of them can be measured by volume.

Safety, and this is not boilerplate. This oven burns fuel and is for outdoor use only. At working temperature the floor is between 700F and 950F and the shell will burn skin on contact. Keep it at least three feet from fences, walls, awnings and overhanging branches, use long-handled tools and EN407 rated heat gloves , keep children and pets well back, never move a lit or hot oven, and never pour water on a hot baking stone. Water flashes to steam instantly and the thermal shock cracks stone.

How does it compare with the alternatives?

Three ovens worth weighing against it, chosen because they are the ones people actually cross-shop rather than the ones with similar prices.

• Ooni Koda 12: A first outdoor oven for one to four people, where portability matters more than heat retention.
• Gozney Roccbox: Almost everybody. It is the single most defensible first oven for a household of two to five.
• Gozney Arc Lite: A household of two to five who want a 14 inch pizza and good build quality without paying Arc prices.

Which comparisons cover this oven?

A head-to-head is usually a faster read than a specification table, because it puts the trade-off in one sentence instead of two columns. These name the Solo Stove Pi Prime directly, and the rest cover the category decisions that apply to it.

• Solo Stove Pi Prime vs Ooni Karu 12
• Gas vs wood fired pizza ovens
• Indoor vs outdoor pizza ovens
• Home oven steel vs outdoor pizza oven
• 12 inch vs 16 inch pizza ovens

Where does it fit in a complete setup?

An oven on its own does not make pizza. The full kit is the oven, a baking surface if the supplied one is thin, a launching peel, a turning peel, a thermometer, dough containers, a scale, a cutter, fuel, and the items nobody thinks about until they are missing: gloves, a brush for the stone and a cover if it lives outdoors. We have costed that out completely at three budgets on the build pages, and the intermediate build is the one that suits most households.

If you are still choosing rather than confirming, the pizza oven roundup covers the whole category by tier, the oven index lists every model we track with its specifications, and the buying guide works through the decisions in the order they actually get made: fuel, then size, then budget.
