Quick Answer: The BakerStone Pizza Oven Box turns a gas grill into a 700-800°F pizza oven for $139.99-$219.99 depending on series, per bakerstonebox.com’s current pricing. Independent testers at TechGearLab and AmazingRibs.com both rate it favorably, and it measured one of the lowest stone-temperature standard deviations (about 21°F) of any grill insert tested — but owners still report the chamber runs hotter toward the back, so turning the pizza every 30-45 seconds matters more here than on a standalone oven.
BakerStone doesn’t sell a standalone pizza oven — it sells a steel-and-ceramic box that sits over your existing gas grill’s burners with the lid propped open, trapping heat into a low chamber that bakes like a real pizza oven. It’s the cheapest way into genuine 700°F+ pizza if you already own a decent grill. Here’s what the official pricing, independent testing, and real owner feedback add up to.
BakerStone pizza oven by the numbers
- $139.99: the sale price of the Original Series Pizza Oven Box, BakerStone’s core model, per bakerstonebox.com (regular price $159.99).
- 700-800°F: the real stone temperature independent reviewers and owners measure with an infrared thermometer after a ~20-25 minute preheat on a 3-burner-or-larger gas grill — well above a home oven’s ~550°F ceiling per the U.S. Department of Energy.
- ~21°F: the stone-temperature standard deviation TechGearLab-style testing found for the BakerStone, one of the tightest of any grill-top insert tested — evidence that “uneven cooking” complaints are more about turning technique than the box itself.
- 3 series: Basics ($129.99-$169.99), Original ($139.99-$159.99), and Professional ($179.99-$219.99), each adding more insulation and accessories at a higher price, per the brand’s own site.
The BakerStone Original Pizza Oven Box
BakerStone Original Pizza Oven Box
- Steel-and-ceramic chamber lined with a cordierite stone; sits directly over your grill's grates with the lid propped open.
- Reaches 700-800°F at the stone after roughly 20-25 minutes of preheating with all burners on high, per independent testing.
- No new appliance to store — lift it off when you're done and the grill goes back to being a grill.

TechGearLab’s testers called it “an immediate favorite from the first firing” for its control and consistency, and AmazingRibs.com — which reviews independently of manufacturer influence — rated it as one of only two grill-top inserts that genuinely improve the pizza-making process. At $139.99-$159.99, it’s a fraction of the cost of a dedicated outdoor oven, provided you already own the grill it sits on.
The full BakerStone lineup
| Series | Price | Best for |
|---|---|---|
| Basics Series | $129.99 (box) / $169.99 (kit w/ peel + turner) | Cheapest entry, includes tools |
| Original Series | $139.99-$159.99 | Best value — the core model most reviewers test |
| Professional Series | $179.99 (box) / $199.99 (kit) | Extra insulation for back-to-back bakes |
| Indoor Series (stovetop) | ~$139.90 | Converts a gas kitchen range or camp burner instead of a grill |
The Professional Series’ added insulation layer is the one upgrade worth paying for if you’re regularly baking for a group — it holds heat better between pies, so you spend less time waiting for the stone to recover. For an occasional-use box that still hits real pizza-oven temperatures, the Original Series is the better value.
What owners actually complain about
Independent tests and owner reviews across Best Buy, Walmart, and Home Depot converge on a few consistent points, worth knowing before you buy:
- Hotter toward the back: the chamber isn’t perfectly even — the side near the opening runs hottest, so a pizza left in one spot chars unevenly.
- Requires active turning: rotating the pizza every 30-45 seconds is non-negotiable, more so than on a standalone oven with a rotating stone.
- Grease trap and griddle accessories run small: on combo kits that add a griddle, some owners find the grease trap undersized for regular use.
- Storage sleeve wears fast: the included protective cover for the stone is a loose fit and tears with repeated use — worth a separate storage bag.
- Runs your grill hard: sustained pizza sessions mean all burners on high for 20+ minutes; a smaller 2-burner grill will struggle to hold temperature the way a 3-burner-plus grill does.
None of these are disqualifying — TechGearLab and AmazingRibs.com both still recommend it — but they explain why a $140 grill insert isn’t a drop-in replacement for a $500+ standalone oven’s insulation and evenness.
How it compares to other grill-top pizza options
| Option | Type | Max temp | Price |
|---|---|---|---|
| BakerStone Original | Gas-grill insert | ~800°F | $139.99-$159.99 |
| KettlePizza Deluxe | Charcoal-kettle insert | ~800-900°F | ~$250 |
| Ninja Woodfire Outdoor Oven | Standalone all-in-one | ~700°F | ~$350 |
| Ooni Koda 2 | Standalone dedicated oven | ~950°F | ~$499 |
If you already own a gas grill, the BakerStone is the cheapest path to genuine pizza-oven heat. If you grill with charcoal instead, a KettlePizza kit does the same job and runs hotter with more smoke flavor. If you don’t own a grill at all, a standalone box like the Ninja Woodfire or a dedicated oven skips the “already own a grill” requirement entirely.
Who should buy the BakerStone pizza oven
- Buy it if you own a 3-burner-or-larger gas grill and want real 700-800°F pizza without buying a whole new appliance.
- Buy the Professional Series if you regularly cook for a group and need better heat retention between pies.
- Buy the Indoor Series if you want stovetop pizza and don’t have outdoor space at all.
- Skip it and buy a KettlePizza if you grill with charcoal — the insert format is nearly identical but tuned for a kettle instead of a gas grill.
- Skip it and buy a standalone oven if you don’t already own a grill, or if you want a rotating stone and more even heat without managing the turn-every-30-seconds discipline.
Whatever you land on, an infrared thermometer is the cheapest way to confirm the stone’s real temperature — especially useful on a grill insert, where heat varies more by position than it does on a purpose-built oven.
Infrared Thermometer
- Confirms exactly where in the chamber the stone runs hottest, so you know when to turn.

The bottom line
The BakerStone Pizza Oven Box is the least expensive way to get genuine 700-800°F pizza-oven heat if you already own a gas grill — $139.99-$159.99 for the Original Series, tested favorably by both TechGearLab and AmazingRibs.com. The real trade-off is heat distribution: the chamber runs hotter toward the back, so turning every 30-45 seconds is mandatory, not optional. If that discipline sounds like a hassle, a standalone oven with a rotating stone costs more but asks less of you mid-bake.
