Buy the standard Gozney Dome Gen 2 if you want a 16-inch deck, a stone you can replace yourself, and parts support that will still exist in two years; step up to the Dome XL Gen 2 only if you regularly cook for a crowd and have permanent room for a 161 lb oven. The outdoor pizza oven market tends to treat the Dome as one product, but the name now covers three very different ovens.
The original Dome (Gen 1) launched in April 2021. The simplified gas-only Dome S1 followed in October 2023, and both are now discontinued. Gozney replaced them on October 15, 2025 with the two-model Dome Gen 2 Series: the standard Dome Gen 2 and the larger Dome XL Gen 2.
Peak temperature does not separate the three. All of them sit in the same heat class, with Gen 1 and Gen 2 both landing in the low- to mid-900s °F. What actually differs is usable cooking area, whether the floor stone comes out without a fight, and how much of the oven can be serviced instead of replaced.
Here is how the three compare at a glance:
| Gozney Dome Gen 1 | Gozney Dome Gen 2 | Gozney Dome XL Gen 2 | |
|---|---|---|---|
| Status | Discontinued | Current flagship | Current large-format flagship |
| Cooking area | Not listed | 398.2 sq in | 519.9 sq in |
| Pizza capacity | 1 × 16 in | 1 × 16 in or 2 × 10 in | 1 × 18 in, 2 × 12 in or 3 × 10 in |
| Pan capacity | Not listed | 1 × 10×14 in + 2 × 8 in | 2 × 10×14 in + 2 × 6 in |
| Cooking floor | 30 mm cordierite, not user-removable | 30 mm removable, two pieces | 30 mm removable, two pieces |
| Weight | 128 lb | 136.7 lb | 161 lb |
| Maximum temperature | ~500°C / low-900s °F | 950°F | 950°F |
| Replaceable components | Limited | 25+ | 25+ |
| Built for | Deal hunters who can source parts | Most backyard cooks | Large-group entertainers |
What Actually Changed Across the Three Domes
Gozney sells the Gen 2 redesign on heat, but the temperature ceiling barely moved. The numbers that changed are space and serviceability.
Standard Gen 2 carries 398.2 sq in of cooking area, which Gozney rates at more than 40% above the original Dome. The XL measures 519.9 sq in, which Gozney puts at 90% more than the original. Extra floor converts into capacity: the standard model fits one 16-inch pizza or two 10-inch pies, while the XL takes one 18-inch, two 12-inch, or three 10-inch pizzas, or two 10×14-inch pans plus two 6-inch pans.
Both Gen 2 models move to a 30mm cordierite floor that lifts out in two pieces without tools. The Gen 1 floor was not designed as a user-removable part, and that single change does more for long-term value than any peak-temperature claim. Gozney states that more than 25 Gen 2 components can be replaced or serviced, the stone included.
The burner is the third shift. Gen 2 uses a lateral rolling flame that curves around the chamber instead of consuming usable floor, and that repositioning is what frees the extra deck. Both models share the same control set: incremental low-to-high flame adjustment, push-turn ignition, real-time floor and air temperatures, a cook timer, and two meat probes on a rechargeable USB-C quick-swap battery. The console works without an app.
Construction is consistent across the pair, with three-layer commercial-grade insulation inside a ceramic-coated aluminized-steel shell and 304 stainless-steel burner and internal components. Both arrive fully assembled, though Gozney recommends four people for unboxing because of the weight. Body colors are Bone and Off Black only, and there is no Olive Gen 2.
Gozney Dome Gen 1: What You're Buying Second-Hand
The original Dome launched in April 2021 and is discontinued. What you find today is residual retailer stock or a used unit, which makes the buying math different from a new oven.
- Weight: 128 lb / 58 kg
- External: 28.9 in W × 24.9 in D × 26 in H
- Internal: 21.65 in W × 18.5 in D × 7.5 in H
- Mouth: 16.2 in W × 4.7 in H
- Cooking floor: 30 mm / 1.2 in cordierite
- Capacity: one 16-inch pizza plus a small side dish
- Construction: 304 stainless-steel internal shell, ceramic-bonded exterior, dense calcium and magnesium-silicate insulation
- Fuel: wood-capable and dual-fuel configurations, with propane the principal bottled-gas version and natural-gas variants in some markets
- Instrumentation: integrated digital temperature monitoring and two meat probes
Gozney's historical guidance for the Gen 1 put live-fire cooking at up to 500°C, roughly 932°F, and US marketing commonly rounded that class of oven to about 950°F.
The Gen 1 was the more versatile of the two flagship generations in one specific sense. It supported Gozney's Flex Fire wood-and-gas approach and a line of accessories for baking, smoking and steaming that the gas-only S1 later dropped. The Rope-Sealed Door and Steam Injector were built to work together for bread baking, and they remain genuine Gen 1 differentiators if you can still find them.
That "if you can still find them" is the problem. Owner discussions through 2026 describe hunting secondary retailers and auction listings for Gen 1 flues, mantels and other parts that are no longer being replenished. Stone cracking is the most frequently reported Gen 1 ownership complaint, and because the original floor was not designed as a straightforward user-replaceable part, the repair path is harder than on a Gen 2. Ignition and flame-retention complaints recur as well, along with reports of difficulty reaching temperature in cold conditions and occasional weak natural-gas flame.
None of that makes every Gen 1 a bad oven. Long-term ownership reports are genuinely mixed: one owner has cooked roughly four days a week for three years with good results, while another describes exterior rim rust and pitting with the interior still functional.
The defensible read is that a cheap Gen 1 can still be an excellent cook, but the discount has to compensate for parts risk. Before committing to one, work through a structured used pizza oven checklist rather than trusting the listing photos.

The standard Gen 2 is the sensible default. It is a few inches wider and about 9 lb heavier than the Gen 1, and its internal height grows from 7.5 in to 8.9 in. That extra height matters more than the width if you want to roast or bake in pans as well as launch pizzas, because taller interiors clear a cast-iron skillet without scraping the ceiling.
Fuel flexibility is real but narrower than it reads. Gen 2 supports wood, charcoal and propane, and Gozney now offers dedicated natural-gas versions in the US, but the fuel type is chosen as a model variant at purchase rather than converted on the bench. Propane and natural-gas Domes use different burners and regulators, so a DIY swap is not a supported job. The fuel comparison guide covers what each option costs you in effort.
US buyers can also look for SKU GMPOBUS1625 (Off Black, propane) if they want to confirm they are getting the standard model rather than the XL.

Gozney Dome XL Gen 2: Specs and Analysis
- Announced September 10, 2025, released October 15, 2025

The XL is the same architecture scaled up, and it exists for volume. One 18-inch pizza, two 12-inch pies, or three 10-inch pizzas. Two 10×14-inch pans plus two small pans. The mouth opens to 18.5 × 5.5 in, which genuinely helps when you are launching a larger pie.
Capacity figures still deserve reading with care. Owners cooking at Neapolitan temperatures report that fitting two or three pizzas is a floor-space specification, not a guarantee of easy simultaneous baking. At 60 to 90 seconds a pie, launching and turning several pizzas becomes the bottleneck long before the deck runs out of room. XL owners make the same point from the other direction: the oven is comfortable for a 16-inch pizza, while a full 18-inch pie needs more careful turning near the flame.
There was never a mainstream Gen 1 Dome XL, so anyone weighing a used XL listing is looking at a Gen 2-era product with no direct predecessor to discount against. A limited 2026 Tonester "Black Orange" colorway exists, but it has sold out, Gozney says it will not be restocked, and it is a cosmetic variant rather than a new generation.

Cooking Area and the Usable Deck
Two numbers get quoted for any Dome, and only one of them tells you how the oven cooks. Cooking area is a floor measurement. Usable deck is the space you can launch into without clipping a burner, and it is the figure that changes when the flame gets rerouted.
The Gen 2 lateral burner curves around the chamber rather than sitting across the floor, which is why 398.2 sq in on a Gen 2 feels roomier than its raw dimensions suggest when you stand it next to the Gen 1's 21.65 × 18.5 in interior. On the Gen 1, the burner arrangement and the mouth geometry leave less clear deck than the interior measurement implies.
Practical pizza size lands below the headline number on every version. A 16-inch oven turns 12 to 14-inch pizzas comfortably with room to maneuver, and a full 16-inch pie is possible but tighter. On the XL, 14 to 16-inch pizzas are the comfortable range, and an 18-inch pie demands attention near the flame. If you are still deciding how much oven you need, the pizza oven sizing guide walks through capacity against working room.
Stone, Insulation and Serviceability
All three Domes use a 30mm cordierite cooking floor, so the material itself is not a differentiator. What changed is who can take it out.
On Gen 2, the stone comes free in two pieces without tools, and Gozney lists more than 25 replaceable or serviceable components. On Gen 1, the floor was not designed as a simple user-removable part, which is why owner reports of a cracked Gen 1 stone tend to end in a more involved repair than the same fault on a Gen 2.
Insulation differs by generation too. Gen 1 uses dense calcium and magnesium-silicate insulation inside a ceramic-bonded exterior. Gen 2 steps up to three-layer commercial-grade insulation behind a ceramic-coated aluminized-steel shell with 304 stainless internals. In practice, heavier insulation means slower warm-up and slower cool-down with better heat held in between, which suits a permanent patio installation more than a knock-down-and-pack-away setup.
One maintenance rule applies to all three: keep the cooking floor dry. Gozney recommends a waterproof cover during non-use for exactly this reason, and the same care applies whether you own a 2021 or a 2025 oven. The pizza stone care guide covers the cleaning rules that keep a cordierite floor alive.
Owner-Reported Problems Worth Knowing About
On the Gen 1, the three recurring themes are stone cracking, ignition and flame retention, and parts sourcing. Difficulty reaching temperature in cold weather and occasional weak natural-gas flame show up as well, though operating conditions clearly shape those reports.
The Gen 2's single most common operational complaint is ignition behavior. Some owners say the propane unit regularly needs a second attempt, or requires holding the control in for roughly 30 to 60 seconds while the thermocouple warms. Separate 2026 reports describe the pilot lighting without establishing a full burner flame, with some users tracing it to obstruction or insects in the gas plumbing and others receiving warranty help.
One owner's direct comparison found the original Dome more even, describing the Gen 2 burner as small relative to its larger chamber, with slower recovery and hot-cold spots. That is a single owner's view rather than a majority position, and other long-term users report strong heat recovery and low heat loss on the same oven, so treat it as a genuine disagreement rather than a verdict. Separately, several standard-Dome owners report a loose or wobbly mantel fit, while at least one XL owner in the same discussion had no such problem.
The XL has no meaningful defect pattern attached to it. Early launch-period threads contain isolated reports of delivery delays, accessory backorders, scratches, and one broken stone alongside plenty of units that arrived in perfect condition.
One safety note deserves repeating because owners miss it constantly: the Gen 2 Door is for baking, smoking and slow roasting, and Gozney explicitly states it must not be used while the gas burner is lit.
Fuel Options and Setup
Gen 2 and the XL run on wood, charcoal and propane, and Gozney now sells dedicated natural-gas versions in the US. The choice is made at purchase, because propane and natural-gas models use different burners and regulators, and there is no supported field conversion.
That point matters, because community threads still suggest a DIY propane-to-natural-gas swap on these ovens. The advice ignores both the supply-pressure differences and the warranty consequences, and it is not installation guidance anyone should follow. If you want natural gas, buy the natural-gas variant. If you are choosing between the two fuels, the gas versus wood-fired breakdown covers the trade-offs.
For buyers who genuinely intend to cook over wood, the optional Wood-Fire Control Kit adds powered airflow and gets you closer to gas-like control of a live fire. It does not make wood as effortless as turning a dial, and it is close to pointless for anyone who defaults to propane.
Accessories Worth Buying
Start with the essentials and leave the rest until you know how you actually cook.
- Weather cover. This is the first purchase rather than the last, because Gozney's own guidance calls for keeping the stone dry on a heavy outdoor appliance. The pizza oven cover guide covers the fit differences between generations.
- A launching peel and a turning peel. A 16-inch perforated peel for the launch and an 8-inch turning peel for mid-bake quarter-turns. The peel guide has sizes by oven.
- An infrared thermometer. Even with Gen 2's built-in floor sensing, an IR gun lets you check several points across the deck and confirm recovery between pizzas. Options are in the thermometer guide.
- Mantel. Repeatedly described as the most useful dedicated accessory once you move past pizza into pans and staging food. Check the fitment, given the wobble reports on the standard model.
- Wood-Fire Control Kit. Worth it if you cook with wood regularly; unnecessary for gas-first owners.
- Door. Useful for baking and slow roasting, subject to the live-flame restriction above.
- Neapolitan Arch. Narrows the mouth for faster heat retention in cold or windy weather, but it also reduces working clearance and divides opinion. Optional.
- Stand. Convenient and purpose-built, though owners frequently describe it as expensive and some build their own support instead. Alternatives are covered in the tables and stands guide.
Which Dome Should You Buy?
For most backyard cooks, the standard Dome Gen 2 is the correct answer. It gives you a 16-inch deck, two-pizza capacity in a pinch, a stone you can swap yourself, and the accessory ecosystem that will keep receiving support. It is also the version that best balances footprint against output for a normal household.
Buy the Dome XL Gen 2 if you host regularly and have a permanent spot for it. The 519.9 sq in deck and 18-inch capacity are real, and the XL is the only Dome that comfortably handles 12-inch pizzas two at a time. Be honest about whether you can launch and turn at that pace, because the extra floor does not fix a slow workflow.
Consider a used Dome Gen 1 only if the price is genuinely low and you have verified that the accessories and spare parts you want are still obtainable. It remains a capable oven, and some experienced owners prefer its heat distribution, but the floor is harder to replace and the support picture is shrinking.
On fuel, gas-first buyers should take a propane or natural-gas Gen 2 and stop there. Buyers who want live fire as the point of the oven should budget for the Wood-Fire Control Kit from the start.
One comparison worth making before you commit: if smoking and grilling are your main goals and pizza is secondary, a kamado is the better tool. The Dome is at its strongest when high-temperature oven cooking and pizza dominate, and the brand comparison puts it against the Ooni and Blackstone alternatives.
Frequently Asked Questions
Q: Is the Gozney Dome Gen 1 still worth buying?
Only at a real discount. The Gen 1 still cooks excellent pizza, and some owners have run theirs for years with no trouble, but the floor is not designed for simple user replacement and parts have become harder to source since the Gen 2 launch. Price the risk in, and verify that any accessory you want actually exists before you buy.
Q: Can you convert a propane Dome Gen 2 to natural gas?
No. Propane and natural-gas Domes are separate model variants with different burners and regulators, and Gozney does not support a field conversion. Buy the fuel configuration you need at purchase, and treat any DIY conversion advice on forums as unsafe rather than thrifty.
Q: Does the Dome XL actually cook two or three pizzas at once?
It physically fits them, but simultaneous Neapolitan baking is a workflow question rather than a space question. At 60 to 90 seconds per pizza, launching and rotating several pies is the limiting factor, and owners report that an 18-inch pizza needs careful turning near the flame even on the XL. The capacity is real for pan cooking and slower bakes; treat the two and three-pizza figures as floor space.
Q: Can you use the Dome Gen 2 door with the gas burner on?
No. Gozney states that the door is intended for baking, smoking and slow roasting, and it must not be used while the gas burner is lit. It is a recurring source of owner confusion, so confirm the restriction before your first cook rather than after.
Q: Do you need the Gozney stand?
Not strictly. The oven works on any stable, heat-tolerant surface, and the official stand is widely described as expensive. A purpose-built stand does make the taller Gen 2 and XL easier to work with and keeps the oven at a comfortable launch height, which matters more as the oven gets heavier.
Conclusion
The Dome family is now a clean two-way choice between the standard Dome Gen 2 and the Dome XL Gen 2, with the discontinued Gen 1 sitting off to the side as a value gamble. The Gen 2 generation did not raise the temperature ceiling in any meaningful way. It fixed the two things that actually shorten an oven's life and limit its output: usable deck space and the ability to replace a cracked stone without a fight.
For most buyers, the standard Dome Gen 2 is the pick. It fits a 16-inch deck, handles two 10-inch pizzas, supports wood, charcoal and propane, and comes with a serviceable architecture that the Gen 1 never had. The Dome XL Gen 2 is the right upgrade for households that host often and can commit permanent patio space to a 161 lb oven, provided they can actually keep up with the bake pace the larger deck invites.
The Gen 1 still turns out great pizza, and some long-time owners prefer how it distributes heat. But a used unit is a parts-and-support decision as much as a cooking decision, and that calculation gets worse every year now that the model is out of production.
If you are still weighing the wider field, start with the best outdoor pizza ovens roundup and the used buying guide if a second-hand Gen 1 is on your shortlist. For everything the current generation needs on day one, the cover guide and the stands guide cover the two accessories owners most often wish they had bought alongside the oven.
