The best pizza stone for Kamado Joe grills is the Hans Grill Circular Pizza Stone for its 15 in cordierite surface and included wooden peel. Choose the Kamado Joe 15-inch ceramic stone when you have a Classic Joe 18 in grill, or move to a 20 in Kamado Joe stone for a Big Joe.

The right match depends on your Kamado Joe model, the stone's diameter and the space left around it. A stone that fits the grill opening can still be awkward if it blocks airflow, sits too close to the sides or leaves no room to handle the pizza.

How we ranked the best pizza stones for Kamado Joe

The best pizza stone for Kamado Joe grills matches the grill model before it adds extra tools or a larger cooking surface. We compared the listed size, material, heat rating, included pieces and stated compatibility, then weighed those details against how a Kamado Joe is normally used.

Kamado Joe's model fit carries extra weight here. The 15 in KJ-PS23 is made for the Classic Joe 18 in charcoal grill and smoker, while the 20 in BJ-PS24 is made for Big Joe I, II and III models.

A general-purpose 15 or 16 in stone can be useful, but it needs a separate clearance check.

Cordierite appears across several picks because it is designed for heat retention and moisture control. Ceramic stones from Kamado Joe are more closely matched to the named grill families, while larger general-purpose stones can work for outdoor setups only when their size and support are suitable.

We did not use prices, star ratings or review counts in the ranking. Our score weighs specs, features and buyer feedback against what you are shopping for.

1. Hans Grill Circular Pizza Stone: Best for most Kamado Joe owners

Hans Grill Circular Pizza Stone: Best for most Kamado Joe owners

Hans Grill Circular Pizza Stone, pizza stones for Kamado Joe grills
9.7/10Our score
  • 15 in round cordierite stone
  • Heat resistant to 1112 F
  • Wooden peel included
  • For oven and BBQ grilling

The 15 in round format fits many grill setups while leaving room to check clearance before cooking. The wooden peel makes this a useful starting set for pizza, bread, pastry and calzone.

See it on Amazon

Pros

  • 15 in round cooking surface
  • Includes wooden peel
  • Heat resistant to 1112 F

Cons

  • Round shape may not suit larger rectangular bakes
  • Hand wash with warm water only

The Hans Grill Circular Pizza Stone is the strongest general pick because its 15 in round cordierite surface fits the size range many Classic Joe owners can consider. Its 0.6 in thickness gives the stone a substantial baking surface, but you should still measure the open area around the heat deflector and cooking grate.

The stone is heat resistant up to 1112 F and is made for oven baking and BBQ grilling. If you use a steel instead, see the pizza steel oven guide.

Hans Grill also describes it for pizza, bread, pastry, pies, frozen pizza and calzone, so it can cover more than one cooking task.

A wooden peel is included, which helps you transfer dough without adding a separate tool to the first order. The care instruction is simple: hand wash with warm water only.

Stains are normal and do not affect the stone's function.

Choose this pick when you want a round 15 in stone with a peel and broad oven or grill use. If your Kamado Joe is a Big Joe, compare the 20 in options below instead.

2. Kamado Joe 15-inch Ceramic Pizza Stone: Best for Classic Joe grills

Kamado Joe 15-inch Ceramic Pizza Stone: Best for Classic Joe grills

Kamado Joe 15-inch Ceramic Pizza Stone, pizza stones for Kamado Joe grills
9.6/10Our score
  • 15 in ceramic pizza stone
  • Compatible with Classic Joe 18 in charcoal grills and smokers
  • Heat deflector required
  • Dishwasher safe

This is the most direct match for the Kamado Joe Classic Joe 18 in grill and smoker. The heat deflector must be used with the stone to help prevent burning.

See it on Amazon

Pros

  • Designed for Classic Joe 18 in models
  • Ceramic construction
  • Kamado Joe system match

Cons

  • Heat deflector is required
  • Stone only is included

The Kamado Joe 15-inch Ceramic Pizza Stone is the clearest fit for a Classic Joe 18 in charcoal grill and smoker. Its KJ-PS23 model is made for Classic Joe, so it removes some of the guesswork that comes with a general-purpose stone.

The ceramic surface is designed to distribute heat and absorb excess moisture for a crisp crust. It is a single stone with a 15 in size, and the care instructions identify it as dishwasher safe.

The key setup rule is the heat deflector. Kamado Joe says the Heat Deflector must be used with the Pizza Stone to avoid burning the pizza, so plan the stone as part of an indirect cooking arrangement rather than placing it directly over the hottest charcoal.

This is the best choice when exact Classic Joe compatibility matters more than getting a peel or extra accessories. For a broader comparison of Classic Joe sizes, see our best kamado joe classic pizza stone guide.

Hans Grill Rectangular Pizza Stone with Peel: Best for rectangular baking

Hans Grill Rectangular Pizza Stone with Peel, pizza stones for Kamado Joe grills
9.4/10Our score
  • 15 x 12 in rectangular cordierite stone
  • Heat resistant to 1112 F
  • Wooden peel included
  • For oven and BBQ grilling

The rectangular shape gives you a different layout from a round stone while staying close to the size of the circular Hans Grill pick. It suits pizza, bread, pastry, calzone and frozen pizza.

See it on Amazon

Pros

  • Rectangular cooking area
  • Includes wooden peel
  • Heat resistant to 1112 F

Cons

  • Needs clearance checks on smaller grills
  • Hand wash with warm water only

The Hans Grill Rectangular Pizza Stone gives you a 14.96 x 11.8 in cordierite surface with a wooden peel. Its rectangular layout can suit breads, pastry and other bakes that do not need a round stone, while the 0.59 in thickness stays close to the circular Hans Grill option.

It is heat resistant up to 1112 F and is intended for oven baking and BBQ grilling. If you are considering a dedicated pizza oven, read our Ooni Karu 2 Pro review.

Hans Grill describes it for Italian-style pizza, pies, pastry, frozen pizza, calzone and artisan bread.

The included peel makes the set easier to use from the start. Hand wash it with warm water only, and expect marks from normal cooking.

Those stains do not change the stone's function.

Choose this pick if the rectangular shape fits your grill better than a round stone. On a Classic Joe, measure the usable grate area and the clearance around the heat deflector before heating it.

Old Stone Round Pizza Stone: Best for high heat in a home oven

Old Stone Round Pizza Stone, pizza stones for Kamado Joe grills
9.2/10Our score
  • 16 in round stoneware
  • Maximum temperature of 1472 F
  • Made from lead-free clay blend
  • Recommended up to 500 F in a standard home oven

This 16 in stone gives you a larger round surface than the 15 in options. Its standard home oven recommendation is 500 F, so check the cooking temperature and Kamado Joe clearance before using it on a grill.

See it on Amazon

Pros

  • 16 in round surface
  • Lead-free clay blend
  • High stated maximum temperature

Cons

  • Do not clean with soap
  • Standard home oven recommendation is up to 500 F

The Old Stone Round Pizza Stone gives you a 16 in round stoneware surface made from a blend of lead-free clays. Its larger diameter may suit a Big Joe-style setup or a large oven, but the extra inch over a 15 in stone makes clearance more important on a Classic Joe.

The stone is listed with a maximum temperature of 1472 F, while its standard home oven recommendation is up to 500 F. That difference means you should match the cooking temperature to the appliance and setup rather than relying on the maximum number alone.

Old Stone describes the surface as absorbing oven heat and transferring it evenly. It can be used for pizza, bread, pastries and vegetables.

Care is a trade-off here. Do not clean this stone with soap, and use a dry cloth according to the care instructions.

Pick it when you want a larger round cooking area and can confirm the Kamado Joe's clearance.

9.0/10Our score
  • 15 in cordierite stone
  • Heat resistant to 1450 F
  • Plastic scraper included
  • For oven and grill

The 15 in cordierite surface is made for oven or grill use, and the scraper helps remove residue from a cool stone. Its 0.6 in thickness is close to the Hans Grill circular option.

See it on Amazon

Pros

  • 1450 F heat resistance
  • Includes plastic scraper
  • For oven and grill use

Cons

  • Scraper is for a cool stone only
  • No peel included

The Unicook 15 in round cordierite stone suits a Classic Joe-sized setup when you want a high heat rating and a compact accessory package. It measures 15 x 15 x 0.6 in and is intended for both oven and grill use.

Unicook describes micro-pores that absorb moisture from dough and support a crisp crust. The stone is heat resistant up to 1450 F, and the included plastic scraper can remove residue from the surface after the stone cools.

The scraper is not a substitute for a peel. You will need another way to move raw dough onto the stone, but the scraper is useful for cleaning off baked residue without using soap or detergent.

Preheat the stone before cooking, and let it heat gradually with the grill. Choose this pick when the 15 in round format works for your Kamado Joe and you want a scraper rather than an included peel.

Weber® Gourmet BBQ System Pizza Stone: Best for Gourmet BBQ System grates

Weber® Gourmet BBQ System Pizza Stone, pizza stones for Kamado Joe grills
8.8/10Our score
  • 16.7 in cordierite stone
  • Carry rack included
  • Fits Gourmet BBQ System cooking grate
  • Designed for Weber charcoal grills

The carry rack and Gourmet BBQ System fit make this a specialized choice for compatible Weber charcoal grates. On a Kamado Joe, verify the grate and clearance before considering it.

See it on Amazon

Pros

  • Carry rack included
  • Cordierite construction
  • Designed for Gourmet BBQ System grates

Cons

  • System-specific fit
  • Rectangular shape needs clearance planning

The Weber Gourmet BBQ System Pizza Stone is a specialized pick with a 16.7 in cordierite stone and carry rack. It fits into the Weber Gourmet BBQ System cooking grate, where the grate helps keep it in place during grilling.

That system match makes it more natural for a compatible Weber charcoal setup than for a Kamado Joe. If you are considering it for a Kamado Joe, measure the grate opening, the stone's 16.7 x 13.2 in footprint and the 2 in stated thickness before using it.

Those dimensions matter for handling as well as fit. The listed footprint is rectangular rather than round, so the available cooking area runs longer in one direction than the other.

Leave room around the edges for safe lifting and for checking the pizza without crowding the lid or the sides of the grill.

The carry rack makes moving the hot stone easier than carrying the stone alone. Cordierite absorbs moisture during cooking, which is intended to support a light, crisp thin crust.

Care is simple in principle, as the instructions call for hand washing. Let the stone cool fully before washing it, and avoid sudden temperature changes that can stress any stone.

Choose this pick only when the grate and clearance work for your grill. For Weber-specific alternatives, compare our best pizza stone for Weber grill guide.

Gyreuni 13 Pizza Stone for Oven and Grill: Best complete starter set

Gyreuni 13 Pizza Stone for Oven and Grill, pizza stones for Kamado Joe grills
8.7/10Our score
  • 13 in cordierite stone
  • Oak peel and serving rack
  • Steel pizza cutter
  • 10 sheets of kitchen parchment paper

This 5-piece set covers the basic tools for moving, serving and cutting pizza. The 13 in round stone may be easier to place in a smaller grill, but it gives you less surface than the 15 and 16 in picks.

See it on Amazon

Pros

  • Five-piece set
  • 13 in size suits tighter spaces
  • Serving rack helps protect a table

Cons

  • Smaller cooking surface
  • More included pieces than some buyers need

The Gyreuni 13 Pizza Stone set is the most complete option for a buyer who needs several basic tools at once. The 13 in cordierite stone comes with a 12 x 17 in oak peel, a 13 in serving rack, a large steel pizza cutter and 10 sheets of kitchen parchment paper.

The smaller round surface can be easier to place in a tighter grill, but it gives you less pizza area than the 15 and 16 in stones. Its 0.6 in thickness is similar to several larger cordierite picks here.

The stone is heat safe up to 1472 F and is made for oven and grill use. The serving rack can help protect a table from a hot stone, while parchment paper gives you an option for handling dough and reducing contact with the surface.

Let the stone cool before cleaning it with warm water and a brush. Never use soap or detergent.

Choose this set when you value the included peel, rack and cutter more than a larger cooking area.

8.3/10Our score
  • 20 in ceramic pizza stone
  • Compatible with Big Joe I, II and III
  • For Big Joe 24 in charcoal grills and smokers
  • Heat distributes evenly and absorbs moisture

This is the purpose-built size for Kamado Joe Big Joe I, II and III grills. Its 20 in diameter needs the larger grill and careful clearance checks before heating.

See it on Amazon

Pros

  • Designed for Big Joe models
  • 20 in cooking surface
  • Ceramic construction

Cons

  • Too large for Classic Joe grills
  • Heavy at 9.6 lb

The Kamado Joe 20-inch Ceramic Pizza Stone is the direct model match for Big Joe I, II and III charcoal grills and smokers. Its 20 x 20 in size is made for the larger 24 in Big Joe family, so it is too large for a Classic Joe setup.

The ceramic stone is designed to distribute heat evenly and absorb moisture for a hot, crisp pizza. It weighs 9.6 lb, which is worth considering when you plan where to store and handle it.

This is a single pizza stone with no peel included. Its 0.31 in thickness is thinner than the Hans Grill and Unicook cordierite stones, so compare how you want to manage heat and handling before choosing between them.

Pick it when your grill is a Big Joe and you want the Kamado Joe model made for that size. For a general comparison, see Best Pizza Stone For Grill For Kamado Grills.

8.0/10Our score
  • 20 in round cordierite stone
  • Compatible with Kamado Joe Big Joe
  • Heat resistant to 1472 F
  • For gas and charcoal grills

The 20 in round format is intended for Big Joe-sized outdoor grills and large gatherings. Its size is generally unsuitable for a standard indoor oven, so measure the grill opening and support surface first.

See it on Amazon

Pros

  • 20 in round surface
  • 1472 F heat resistance
  • Kamado Joe Big Joe compatibility

Cons

  • Large outdoor-only format for most setups
  • No peel or rack included

The Colenza Extra Large Pizza Stone is a 20 in round cordierite stone for large outdoor grills, including Kamado Joe Big Joe models. Its size can support a large pizza or multiple items, but it is generally not suitable for a standard indoor oven.

The stone is heat resistant up to 1472 F and is described for gas and charcoal grills. At 0.6 in thick, it has a deeper format than the 20 in Kamado Joe ceramic stone, so measure the cooking setup and support points carefully.

Only the pizza stone is included. There is no peel or serving rack in this set, so plan a safe way to move and serve a hot pizza before cooking.

Colenza's care instructions call for hand washing with warm water after the stone cools. Do not use soap, detergent or oil.

Choose it for a Big Joe-sized outdoor setup when maximum surface area matters more than included accessories.

How do you match a pizza stone to your Kamado Joe model?

Match the stone diameter to the grill model first, then check thickness and clearance. A 15 in stone is the practical starting point for a Classic Joe, while a 20 in stone is intended for Big Joe-sized grills.

The Kamado Joe KJ-PS23 is specifically for the Classic Joe 18 in grill and smoker. The BJ-PS24 is specifically for Big Joe I, II and III models, which makes those two stones the simplest choices when your grill model matches.

General-purpose stones can still be useful. The Hans Grill Circular, Unicook and Old Stone options offer 15 or 16 in round surfaces, while the Hans Grill rectangular model gives you a different layout.

Measure the open grate area rather than using the grill's name alone.

Also check the stone's thickness. A thicker stone can change the space available for the pizza and may affect how easily you can place the lid or handle the food.

Leave room around the stone for airflow and safe movement.

Should you choose ceramic or cordierite for a Kamado Joe?

Ceramic is the easiest choice when you want a Kamado Joe stone matched to a named grill family. Cordierite gives you more general-purpose options for oven and grill use, often with different shapes and included tools.

The Kamado Joe 15-inch and 20-inch stones are ceramic models designed for Classic Joe and Big Joe grills. The Hans Grill, Unicook, Weber and Gyreuni stones use cordierite, with heat ratings and care instructions that vary by product.

Do not compare heat ratings by number alone. The Old Stone has a stated maximum of 1472 F but recommends up to 500 F in a standard home oven, while Kamado Joe's 15-inch stone requires a heat deflector to help prevent burning.

Your best choice depends on the whole setup: grill model, stone size, support, heat deflector, cooking temperature and care method.

How should you set up and care for a pizza stone?

Preheat the stone with the grill, cook on a stable surface and let it cool fully before cleaning. Avoid sudden temperature changes, oil seasoning and soap when the product's care instructions prohibit them.

Place the stone according to the grill's indirect cooking setup. The Kamado Joe 15-inch stone specifically requires the Kamado Joe Heat Deflector, so include that step before the pizza goes on the stone.

Dusting dough with flour can help it move onto the stone, and a peel makes that transfer easier. The Hans Grill and Gyreuni sets include wooden or oak peels, while the Unicook set includes a plastic scraper instead.

After cooking, let the stone cool before handling it. Several products call for warm water only and warn against soap or detergent.

Stains are normal on some cordierite stones and do not mean the surface has stopped working.

Is a 20-inch pizza stone too large for a Classic Joe?

Yes, a 20 in stone is generally too large for a Classic Joe setup. The Kamado Joe 20-inch stone is made for Big Joe I, II and III grills, while a Classic Joe 18 in grill is better matched with a 15 in stone.

A 16 in stone may fit some larger setups, but do not assume the grill's outside width equals the usable cooking area. Measure the grate opening and account for the heat deflector, stone thickness and space needed to move the pizza.

The diameter printed on a product page can be misleading on its own. A round stone needs clearance on every side, and a rectangular stone needs a different check along its length and width.

Thickness also matters, because a thicker stone sits higher and can reduce the space above the pizza.

Think about the full cooking setup before you buy. The heat deflector, the support surface and the lid all use space inside a kamado grill.

When those pieces sit together, the safe working area is often smaller than the grate alone suggests.

Handling is another practical limit on a Classic Joe. A large round stone is harder to center, harder to lift with a peel, and harder to remove at the end of cooking.

That difficulty grows when the stone is hot and the opening is already narrow.

For a Classic Joe, start with the Kamado Joe 15-inch stone or compare it with the 15 in Hans Grill and Unicook options. Those sizes leave more margin for airflow, for checking the crust, and for moving the pizza without scraping the sides.

The Hans Grill circular option also includes a wooden peel, which helps with the transfer step. The Unicook option includes a plastic scraper for a cooled stone, but you still need a separate way to move raw dough.

For a Big Joe, compare the Kamado Joe and Colenza 20 in stones. Both are described for Big Joe sized setups, and a 20 in surface can support a large pizza or several items at once.

Do not try to force a 20 in stone into a Classic Joe by removing setup pieces. The heat deflector and a stable support are part of safe cooking, and squeezing a stone in place can make the crust cook unevenly.

If you are between sizes, measure twice and choose the smaller stone that still fits your usual pizza. A well centered 15 in pizza will cook more evenly than a 16 in pizza pushed against the edge of the grill.

Check the stated maximum temperature as well, but do not let a higher number override fit. The right size for your grill model and your normal cooking style will matter more in daily use.

Final verdict: which pizza stone should you buy?

The Hans Grill Circular Pizza Stone is the best pizza stone for Kamado Joe grills for most buyers because its 15 in cordierite surface and wooden peel cover the basic setup without locking you to one grill brand.

That balance is why it suits a wide range of home cooks. You get a round surface for pizza, plus a peel for moving dough, without needing to add separate tools right away.

The stone is also described for bread, pastry, pies, frozen pizza and calzone, so it can handle more than one kind of bake.

Pick the Kamado Joe 15-inch ceramic stone if you own a Classic Joe 18 in grill and want the closest model match. It is made for that grill family, and Kamado Joe says the heat deflector must be used with the stone to avoid burning the pizza.

Pick the Kamado Joe 20-inch ceramic stone for a Big Joe I, II or III, or choose the Colenza 20 in stone when a large general-purpose outdoor surface matters most. Both 20 in options need a Big Joe sized setup, so confirm clearance and support before heating.

For a rectangular shape, choose the Hans Grill Rectangular model. Its 14.96 x 11.8 in surface gives you a different layout for breads, pastry and other rectangular bakes, and it also includes a wooden peel.

For a complete starter kit, choose Gyreuni. The 13 in stone comes with an oak peel, a serving rack, a steel cutter and parchment paper, which covers moving, serving and cutting in one set.

Consider the Unicook 15 in stone when you want a higher stated heat rating and a scraper for a cooled surface. It does not include a peel, so plan for that step if you choose it.

Consider the Old Stone 16 in stone when you want a larger round surface for a home oven setup. Remember its standard home oven recommendation is up to 500 F, and do not clean it with soap.

The Weber Gourmet BBQ System stone is the pick to consider only for a compatible Weber grate. On a Kamado Joe, its system specific fit and rectangular footprint need careful measuring first.

For a more general grill accessory, compare the Best Pizza Stone For Grill guide before ordering.

In the end, match the stone to your grill model, your usual pizza size and the tools you already own. That fit will matter more than any single spec when you cook week after week.

Frequently asked questions

What size pizza stone fits a Kamado Joe Classic?

A 15 in pizza stone is the clearest match for a Kamado Joe Classic Joe 18 in grill. The Kamado Joe KJ-PS23 is made for Classic Joe models, while other 15 and 16 in stones may also fit only when the cooking grate, heat deflector and surrounding clearance leave enough room.

What size pizza stone fits a Kamado Joe Big Joe?

A 20 in pizza stone is the intended size for a Kamado Joe Big Joe. The Kamado Joe BJ-PS24 is compatible with Big Joe I, II and III models, while the Colenza 20 in stone is also described as compatible with Kamado Joe Big Joe grills.

Do you need a heat deflector with a Kamado Joe pizza stone?

Use the Kamado Joe heat deflector with the KJ-PS23 pizza stone because Kamado Joe says it helps prevent the pizza from burning. For other stones, follow the grill and stone instructions, and keep indirect heat and clearance in mind before cooking.

Can you use a regular pizza stone on a Kamado Joe?

You can consider a regular stone if its diameter, thickness and heat rating suit the grill. A 15 or 16 in stone is more practical for a Classic Joe, while a 20 in stone belongs on a Big Joe-sized setup.

Always check clearance before heating.

How do you clean a Kamado Joe pizza stone?

Let the stone cool fully, then follow its care instructions. Several picks here call for warm water and no soap or detergent, while the Kamado Joe 15-inch stone is dishwasher safe.

Do not season a cordierite stone with oil or grease.
