6 Best Big Horn Pizza Oven Stones (November 2026)
The best Big Horn pizza oven replacement stones include the Unicook 12"x12" Square Pizza Stone for Oven for a Big Horn 12 in oven, the Unicook 15 x 12 Inch Rectangular Pizza for a wider rectangular floor, and the BIG HORN Gas Pizza Oven for a matched oven and stone.
On this page (6 sections)
The Unicook 12 x 12 in square stone is the clearest replacement match for a Big Horn 12 in pizza oven because compatibility is specified and its stated heat tolerance is 1,450°F. Measure your oven's interior, allow 1 in of clearance on all sides, and check whether the stone's thickness suits the oven floor.
Replacement-stone shopping comes down to fit first, then thickness and heat tolerance. A stone that is too large can restrict airflow or fail to sit flat, even when its material and temperature rating look suitable.

Which Big Horn pizza oven stone is the best fit?
The Unicook 12 x 12 in stone is the best fit-focused option for a Big Horn 12 in oven because the brand names that oven size as compatible. Every replacement still needs a dimension check against the oven's interior.
We compared the stated dimensions, thickness, material, and maximum heat tolerance for each option. Our score weighs specs, features and buyer feedback against what you're shopping for.

The best Big Horn pizza oven stones by fit and use
The six options below cover a specifically named 12 in Big Horn fit, larger rectangular stones, and one complete oven with a stone included. The product badges show which use each item is best suited to.
Unicook 12"x12" Square Pizza Stone for Oven: Best for a Big Horn 12 in oven
- 12 x 12 in square
- 0.6 in thick
- Cordierite
- Heat resistant to 1,450°F
This square cordierite stone is specified as compatible with Big Horn 12 in pizza ovens. It needs 1 in of clearance on all sides for fit and airflow.
Pros
- Compatibility named for Big Horn 12 in ovens
- 1,450°F stated heat tolerance
- Reversible smooth surface
Cons
- Only fits if the oven has enough interior clearance
- Square shape may not suit every oven floor
The Unicook 12 x 12 in square stone is the most direct match for a Big Horn 12 in oven in this group. Its 0.6 in cordierite body has a stated maximum temperature of 1,450°F, and the square shape keeps its footprint compact.
Unicook names Big Horn 12 in ovens among compatible models. It also calls for 1 in of clearance on all sides, so compare the stone with the oven's usable interior rather than relying on the oven's name or outside dimensions.
The reversible smooth surface offers two usable sides. The included scraper can remove residue, and the cooled stone can be hand washed with warm water; dark areas that develop with use are described as normal.
Choose this when your Big Horn oven has a 12 in cooking floor and the measured interior provides enough space around the stone. If the floor is larger or rectangular, compare the next option's dimensions before deciding.
Unicook 15 x 12 Inch Rectangular Pizza: Best for a wider rectangular floor
- 15 x 12 in rectangular
- 0.6 in thick
- Cordierite
- Heat resistant to 1,450°F
This rectangular stone gives you a larger surface than a 12 x 12 in square. Check for at least 1 to 2 in of clearance on every side before considering it for an oven.
Pros
- Larger rectangular surface
- 1,450°F stated heat tolerance
- Reversible surface
Cons
- Requires more floor space than a 12 x 12 in stone
- Unicook advises checking clearance on all sides
The Unicook 15 x 12 in rectangular stone suits an oven floor that is wider than the square replacement. Its 0.6 in thickness and 1,450°F heat tolerance match the square Unicook, while the longer shape gives more room for personal pizzas up to 11 in.
Unicook recommends at least 1 to 2 in of clearance on every side. That makes this a poor guess for a compact oven: measure the inside width and depth and check the available height before considering the swap.
The cordierite surface is reversible, and the included plastic scraper can also cut dough. The stone is intended for fresh and frozen pizza, bread, rolls, and cookies.
For a bundled option, compare pizza stone and peel sets.
Pick this only when the interior dimensions support the 15 x 12 in footprint plus clearance. A 12 x 12 in oven should lead you back to the smaller square option.
BIG HORN Gas Pizza Oven: Best for a matched oven and stone
- 15 in cooking capacity
- Includes a 14.7 in pizza stone
- Gas powered
- Dual side burners
This is an oven rather than a replacement stone, but it provides a reference point for buyers who may be replacing a stone while reconsidering the oven. Its included stone is stated as 14.7 in.
Pros
- Includes a 14.7 in pizza stone
- Oven capacity fits pizzas up to 14.7 in
- Dual control knobs
Cons
- Not a replacement stone by itself
- Outdoor gas oven rather than a standalone baking stone
The BIG HORN Gas Pizza Oven is included as a reference for buyers comparing an oven and its supplied stone, not as a standalone replacement stone. It has a 15 in size designation, fits pizzas up to 14.7 in, and includes a 14.7 in pizza stone.
Its gas oven uses dual side burners and has a stated maximum temperature of 1,070°F. The package also includes a foldable pizza peel, a stainless steel peel, and a propane regulator hose.
This pick may help if your current stone is damaged and you're considering replacing the complete cooking setup. If you only need a stone, compare the replacement dimensions with your existing oven rather than using this oven's size as a universal Big Horn measurement.
If you need an alternate baking surface, compare steel pizza trays for oven baking.
waykea 12" x 12" Cordierite Square Pizza: Best for a 12 in square alternative
- 12 x 12 in square
- 0.4 in listed thickness
- Cordierite
- Heat resistant to 1,400°F
This cordierite square has the same 12 x 12 in footprint as the Unicook pick. Its thickness appears as 0.4 in in dimensions and 0.6 in in size text, so confirm that detail and measure the oven before ordering.
Pros
- 12 x 12 in square footprint
- Cordierite material
- Heat tolerance stated at 1,400°F
Cons
- Thickness details conflict
- Big Horn fit is not specifically named
The waykea square stone gives you another 12 x 12 in option, with cordierite construction and a stated heat tolerance of 1,400°F. Its compact footprint aligns with the size of the Unicook square, though Big Horn compatibility isn't specifically named.
There is a thickness detail to resolve before choosing it: the dimensions give 0.4 in, while the size text says 0.6 in. Confirm the actual thickness and check clearance in your oven, especially if the current stone sits close to the heating elements.
The stone is intended for ovens and grills and can also be used for bread and pastries. It suits shoppers who want a square format and are comfortable verifying both the fit and the thickness.
VEVOR Pizza Stone: Best for an extra-large oven space
- 20 x 14 in rectangular
- 0.67 in thick
- Cordierite
- Heat resistant to 1,450°F
The extra-large rectangular stone has the greatest surface area in this group. It needs a much larger oven floor than the 12 in Big Horn-compatible stone, so measure carefully and keep the stated clearance around it.
Pros
- Largest stone in this group
- Thicker at 0.67 in
- 1,450°F stated heat tolerance
Cons
- Likely too large for many compact pizza ovens
- Needs 0.8 to 2 in of clearance on all sides
The VEVOR stone is the largest option here at 20 x 14 in, with a thickness of 0.67 in and stated heat resistance up to 1,450°F. That surface needs a large oven floor, so it is more relevant to a larger oven or grill than a compact Big Horn model.
VEVOR calls for 0.8 to 2 in of clearance on all sides. Measure both the floor and the space around it before buying, since the stone's large footprint can rule it out even when the heat rating is suitable.
The cordierite stone comes with a plastic scraper and is intended for pizza, bread, pastries, and reheating food. Choose it when the extra surface area fits your cooking space, not just because the stone is thicker.
Old Stone Pizza Kitchen Rectangular Pizza Stone: Best for a home oven or grill
- 14 x 16 in rectangular
- 0.43 in thick
- Stoneware
- Heat resistant to 1,450°F
This rectangular stone is sized for residential ovens, pizza ovens, and grills. Its 14 x 16 in footprint is substantially larger than a 12 x 12 in replacement, so check the cooking floor before choosing it.
Pros
- Heat tolerance stated at 1,450°F
- Designed for ovens and grills
- Can also bake bread and pastries
Cons
- Large footprint for a compact oven
- Stoneware rather than cordierite
The Old Stone rectangular stone measures 14 x 16 in and is 0.43 in thick. Its stated 1,450°F heat tolerance and use in residential ovens, pizza ovens, and grills make it versatile, but the footprint is far larger than a 12 x 12 in replacement.
Old Stone uses stoneware and describes the stone as absorbing and transferring heat evenly. It can also be used for bread, pastries, and vegetables.
Check the interior carefully before choosing this for a Big Horn oven. It fits best when you have a larger rectangular cooking area and want a stone that can move between an oven and a grill.
How do you measure a Big Horn replacement stone?
Measure the oven's usable interior width and depth, then compare those figures with the stone's full dimensions. Leave the clearance recommended for that stone on every side, and check vertical room if the oven has a low ceiling or heating element.
For the Unicook square, allow 1 in of clearance all around. For the 15 x 12 in Unicook, allow 1 to 2 in; VEVOR calls for 0.8 to 2 in.
A stone's nominal size is not the same as the oven's cooking capacity. A pizza may be smaller than the stone, and the oven still needs open space around the stone for airflow.
Does thickness or heat tolerance matter more?
Fit matters first, then thickness and heat tolerance should match how your oven is used. The listed stones range from 0.4 to 0.67 in thick and from 1,400°F to 1,450°F stated maximum heat tolerance.
The temperature figures are maximum stone ratings, not a promise that every Big Horn oven operates at that temperature. Use the oven's own instructions for heating and preheating, and don't exceed the limits for either part.
Thickness can affect the available clearance and how much material must heat through. Check your current stone's height and the room above it before replacing it with a thicker model.
How do you care for a replacement pizza stone?
Let the stone cool fully before cleaning, then remove loose food with a scraper or brush. The Unicook stones call for hand washing with warm water and no detergent; discoloration over time is normal.
Care instructions vary by stone, so follow the directions for the specific material you choose. Our guides explain how to clean a pizza oven stone and what you need to clean a pizza oven stone.
Which Big Horn pizza oven stone should you choose?
Choose the Unicook 12 x 12 in square if you have a Big Horn 12 in oven and its interior leaves the required clearance. Pick a rectangular stone only when you measure enough floor space for its full dimensions, and choose the BIG HORN oven only if you're comparing a complete oven rather than a replacement part.
If another bakeware format suits your oven, compare pizza pans for the oven.
The best Big Horn pizza oven stone is the one that fits the interior with airflow space and suits the oven's clearance. Confirm dimensions before ordering, then use the stone's care directions to maintain it.

Frequently asked questions
What size replacement stone fits a Big Horn pizza oven?
For a Big Horn 12 in pizza oven, the Unicook 12 x 12 in stone is specifically described as compatible. Measure the oven's interior and allow at least 1 in of clearance on every side so the stone fits and airflow can move around it.
Other Big Horn oven sizes may need different dimensions.
How thick should a Big Horn pizza oven stone be?
Thickness alone doesn't confirm a fit. The square Unicook and 15 x 12 in Unicook stones are both 0.6 in thick, while VEVOR is 0.67 in and the waykea dimensions give 0.4 in.
Check the oven's available height as well as its floor dimensions.
Can I use a larger rectangular stone in a Big Horn oven?
Only if the oven's interior floor has room for the stone and the required clearance. The 15 x 12 in Unicook and 14 x 16 in Old Stone are much larger than a 12 x 12 in square.
Measure the usable floor before buying, including space for airflow.
How should I clean a cordierite pizza stone?
Let the stone cool completely, then scrape away loose food and hand wash with warm water if the care instructions allow it. Don't season cordierite with oil or grease, and expect discoloration to develop with use.
