Which Chefman pizza oven replacement stones stand out?

The Unicook 12 x 12 in stone leads this group for its square format, cordierite material and clear clearance guidance. The other picks offer different footprints, thicknesses and included tools.

If you need another baking surface, compare steel pizza trays for oven baking.

We compared stated dimensions, thickness where available, material and fit guidance. Our score weighs specs, features and buyer feedback against what you're shopping for.

A higher score reflects a stronger match for a replacement stone search, but it cannot confirm compatibility with your exact Chefman model.

Unicook 12"x12" Square Pizza Stone for Oven: Best for a 12 in square cooking area

9.7/10Our score

• 12 x 12 in square
• 0.6 in thick
• Cordierite
• Requires 1 in clearance on every side

A square cordierite stone with clear fit guidance. Confirm the oven's interior size and leave 1 in around every side for airflow.

See it on Amazon

Pros

• Square shape suits a matching cooking area
• Cordierite
• Fit clearance is specified

Cons

• Needs 1 in clearance on every side
• May not suit ovens with a smaller interior

Unicook's square stone measures 12 x 12 x 0.6 in and is made of cordierite. Unicook names compatibility with some 12 in pizza ovens from other brands, but that does not guarantee fit in a Chefman oven.

The key fit detail is clearance: Unicook asks for 1 in on all sides inside the oven. Measure the full interior, then account for this space and the stone's thickness before buying.

Unicook says the stone can withstand temperatures up to 1,450°F. Its reversible smooth surface can be used on either side, and a plastic scraper is included.

Choose this when your Chefman oven has a square cooking area and room for the stone plus clearance. Skip it if the interior is smaller or the stone would sit against the oven walls.

2

Unicook 15 x 12 Inch Rectangular Pizza: Best for a wider rectangular interior

9.6/10Our score

• 15 x 12 in rectangle
• 0.6 in thick
• Cordierite
• Requires 1–2 in clearance on every side

This rectangular stone gives a longer cooking surface. Check the oven for a minimum of 1–2 in of clearance on all sides.

See it on Amazon

Pros

• Longer rectangular surface
• Cordierite
• Fit clearance is specified

Cons

• Largest footprint among these picks
• Needs 1–2 in clearance on every side

This Unicook stone measures 15 x 12 x 0.6 in, giving it a longer rectangular footprint than the square options. Its stated use is for personal pizzas up to 11 in in diameter.

Unicook calls for 1–2 in of clearance on every side for fit and airflow. That makes careful measurement especially important in a compact countertop oven, where the longer side may be the limiting dimension.

The stone is cordierite and is rated up to 1,450°F. It also comes with a plastic scraper that can cut dough or remove residue after baking.

Choose this if your Chefman model has a rectangular interior large enough for the footprint and clearance. For a smaller cavity, a 9 or 11.5 in stone may be easier to fit.

3

Onlyfire 4 pcs Pizza Stone & Peel: Best for a round stone with tools

9.2/10Our score

• 15 in round cordierite stone
• Includes peel, cutter and spatula
• Stone rated to 2,200°F

The round cordierite stone comes with three pizza tools. Its 15 in diameter needs a large enough cooking area.

See it on Amazon

Pros

• Round stone
• Includes three tools
• Cordierite

Cons

• May be too wide for compact ovens
• A kit includes tools you may not need

Onlyfire pairs a 15 in round cordierite stone with a peel, cutter and stainless steel spatula. For a bundled option, compare pizza stone and peel sets.

The set makes sense if you need those tools too, but its large diameter can rule it out for a compact oven.

Onlyfire gives a maximum temperature of 2,200°F for the stone. The round shape also differs from the square and rectangular stones that may be used in some countertop ovens, so compare the oven's supports and interior shape.

Choose this kit only if the 15 in circle fits with open space around it. The included tools add value for transferring and cutting pizza, but they do not solve a stone that is too wide.

4

waykea 12" x 12" Cordierite Square Pizza: Best for a 0.4 in square stone

8.9/10Our score

• 12 x 12 in square
• 0.4 in thick by dimensions
• Cordierite

A square cordierite option with a stated thickness of 0.4 in in its dimensions. Check oven clearance and compare that measurement with your current stone.

See it on Amazon

Pros

• 12 x 12 in footprint
• Cordierite
• Thinner than the 0.6 in square options

Cons

• The size text gives a different thickness
• No specific clearance guidance

waykea's square cordierite stone measures 12 x 12 in. Its dimensions specify 0.4 in thickness, while its size text says 0.6 in, so verify the thickness before choosing it for a close-clearance oven.

The maker gives a maximum temperature of 1,400°F and describes the stone for ovens, grills and RV ovens. Those uses do not confirm fit in a Chefman oven.

This is a practical comparison for buyers who want a 12 in square alternative. Match its footprint with your oven, then resolve the thickness difference if vertical space is limited.

5

waykea 9” Round Small Pizza Stone: Best for a compact round cooking area

8.8/10Our score

• 9 in round
• 0.3 in thick
• Cordierite

The small round cordierite stone fits a compact cooking area. Its 9 in diameter is suited to personal-size pizzas.

See it on Amazon

Pros

• Small footprint
• Cordierite
• 0.3 in thick

Cons

• Limited cooking area
• May be too small for larger pizzas

The waykea round stone is 9 in across and 0.3 in thick, making it one of the smallest options here. Its cordierite construction is rated to 1,400°F.

That compact size can work for a personal pizza or an oven with limited interior width. Check whether the round stone rests securely in your Chefman oven, since a smaller diameter may not sit on the same supports as a larger square stone.

Choose this for a compact cooking area where a 12 in stone would be too large. It may be too small if you regularly bake larger pizzas.

6

Salomayes 12x12 Inch Cordierite Pizza Stone: Best for RV-style square baking

8.5/10Our score

• 12 x 12 x 0.6 in
• Cordierite
• Includes plastic scraper

This 12 in square cordierite stone includes a plastic scraper. Compare its footprint with the Chefman oven's interior before choosing it.

See it on Amazon

Pros

• Square 12 in footprint
• 0.6 in thickness
• Includes scraper

Cons

• No specific Chefman fit guidance
• Requires clearance checks

Salomayes offers a 12 x 12 x 0.6 in cordierite stone with a plastic scraper. The maker lists use in RV ovens and grills, but Chefman compatibility still depends on your model's interior.

The stone is rated to 1,472°F. Its square footprint is close to the Unicook 12 in option, so compare the stated clearance needs and your oven dimensions before choosing between them.

This pick suits buyers who want a square stone and scraper in one package. Leave room around the stone and make sure the oven can accommodate its 0.6 in thickness.

7

American Metalcraft Pizza Baking Stone: Best for a 13 in ceramic round

8.4/10Our score

• 13 in round
• 0.38 in thick
• Ceramic

A thinner ceramic option with a 13 in round shape. Measure the oven's usable width and height before considering it.

See it on Amazon

Pros

• 13 in round footprint
• 0.38 in thick
• Ceramic construction

Cons

• May not fit a narrow oven
• Material differs from the cordierite options

American Metalcraft's ceramic stone measures 13 in round and 0.38 in thick. Its smaller thickness may help when vertical room matters, but the wider diameter still needs a clear fit check.

The stone is intended for pizza, flatbread and calzones. Its material is ceramic rather than cordierite, so compare the oven's instructions and temperature requirements before using it.

Choose it when a 13 in round shape fits your oven and you prefer ceramic. It is a poor match for an interior that only accepts a square stone or a smaller circle.

8

Nuwave Brick Oven-Style 3pc Pizza Kit: Best for a smaller stone and peel

8.2/10Our score

• 11.5 in stone
• 0.4 in thick
• Cordierite stone with stainless steel tools

The 11.5 in cordierite stone comes with a peel and cutter. Its smaller diameter may suit an oven that cannot fit a 12 in stone.

See it on Amazon

Pros

• Smaller stone footprint
• Includes peel and cutter
• 0.4 in thick

Cons

• Maximum temperature is 1,112°F
• Check the oven's interior shape and clearance

The Nuwave kit includes an 11.5 in cordierite stone, a stainless steel peel and a cutter. At 0.4 in thick, the stone is slimmer than the 0.6 in square options.

Its stated maximum temperature is 1,112°F. Check your Chefman oven's operating guidance and interior shape, since the product is described for other oven and grill setups.

Choose this if an 11.5 in stone fits your space and you want a peel and cutter as well. A kit is less useful if you already have those tools.

9

Round Pizza Baking Stone 9" Diameter: Best for a small round stone

7.9/10Our score

• 9 in round
• Stone material
• Non-absorbent surface

This 9 in round stone has a non-absorbent surface. Its thickness is not specified, so check that detail and oven clearance before choosing it.

See it on Amazon

Pros

• Compact 9 in diameter
• Non-absorbent surface
• Round shape

Cons

• Thickness is not specified
• Material is listed as stone

This round baking stone measures 9 in in diameter, but its thickness is not specified. The material is described as stone, with a non-absorbent surface that resists odors, stains and scratches.

Its small footprint may suit a compact oven, but the missing thickness makes it harder to check vertical clearance. Confirm that measurement before deciding, especially if the Chefman oven's heating elements sit close to the stone.

Choose it only after checking both the oven's interior and the stone's thickness. If you need dimensions that are clearer before ordering, consider one of the other small round options.

How should you measure for a Chefman replacement stone?

Measure the oven's interior width and depth at the level where the stone will sit. If a stone does not fit, compare pizza pans for the oven as another bakeware option.

Then compare the smallest of those measurements with the stone's longest dimension and leave the clearance its maker recommends.

For round stones, check the full diameter and whether the oven's supports hold a circle securely. For square and rectangular stones, check both sides because one dimension may be the limiting one.

Thickness matters too. A thicker stone can reduce space above it, so check the distance to heating elements and any fit guidance in your Chefman manual.

If your oven uses a stone smaller than these options, a pizza pan may be a separate way to bake, but it won't serve as a replacement stone. Confirm the oven's approved bakeware before using one.

Does thickness or material matter when replacing the stone?

Yes. Thickness affects how much vertical space the stone uses, while material and the oven's temperature limits should guide safe use.

For other baking-surface materials, compare pizza steel and cast iron.

Most options here are cordierite, with thicknesses from 0.3 to 0.6 in where stated. American Metalcraft uses ceramic, and the 9 in BAKING STONE does not give a thickness.

Do not assume a thicker or higher-temperature-rated stone is automatically a better match. Fit, airflow, and the oven's instructions come first.

How do you care for a replacement pizza stone?

Let a stone cool completely before cleaning it, then follow its care directions. Many cordierite stones can be scraped and rinsed with warm water, while oil and grease should be avoided.

Food marks and discoloration can be normal on frequently used stones. For more care guidance, read What Do You Need to Clean a Pizza Oven Stone? and How to Clean a Pizza Oven Stone?.

Which replacement stone should you choose?

Choose the Unicook 12 x 12 in if your Chefman oven has a square cooking area and can leave 1 in of clearance on every side. Pick the 15 x 12 in Unicook only if your interior can meet its larger footprint and 1–2 in clearance guidance.

For a compact oven, compare the 9 in round waykea and 11.5 in Nuwave by shape and thickness. If you are also comparing stones for another oven brand, see our guide to the best Big Horn pizza oven stone.

Frequently asked questions

How do I know if a replacement stone fits a Chefman pizza oven?

Measure the oven's usable interior width and depth, then compare those dimensions with the stone. Leave enough side clearance for airflow; Unicook specifies 1 in for its 12 x 12 in stone and 1–2 in for its 15 x 12 in stone.

Also check the space above the stone and whether the oven uses a square or round cooking surface.

Is cordierite or ceramic better for a replacement stone?

Cordierite is the most common material among these picks, while American Metalcraft offers a 13 in ceramic option. Compare the material and maximum temperature for the specific stone with your oven's requirements.

A material label alone does not confirm that a stone fits a particular Chefman model.

Can I use a larger stone if it almost fits?

No. A stone that crowds the oven can limit airflow or contact the oven walls.

Follow the clearance guidance for the stone and leave room around it.

If you cannot meet that space, choose a smaller size that fits without forcing it into place.

How should I clean a cordierite pizza stone?

Let the stone cool fully, then scrape off stuck food and use warm water if its care instructions allow it. Avoid oil or grease on cordierite, and skip soap unless the stone's instructions say otherwise.
