Looking Beyond the BMMXBI 19.8In Half-Moon Ceramic Pizza? 6 Alternatives Worth a Look

How each alternative compares

Kamado Joe 15-Inch Ceramic Pizza Stone

The Kamado Joe 15-Inch Ceramic Pizza Stone targets Classic Joe 18-inch grills rather than the Big Joe series. Its 0.24-inch thickness makes it significantly thinner than the BMMXBI’s 3.27-inch heat deflector. You get a dedicated baking surface instead of a thick insulator. This stone weighs only 2 pounds, compared to the BMMXBI’s 7.6 pounds. It fits smaller grills and offers precise heat distribution for crust texture. Choose this if you own a Classic Joe and want a traditional pizza stone. You sacrifice the thick heat retention and smoking capabilities of the thicker deflector. The white ceramic material provides a clean look but requires different maintenance than the green BMMXBI option.

Kamado Joe Classic Joe I 18-Inch Ceramic Grill

The Kamado Joe Classic Joe I is a complete 18-inch ceramic grill, not just an accessory. It weighs 188 pounds and stands 18.9 inches tall. This is a dedicated cooking appliance, whereas the BMMXBI is a replacement part for existing grills. You gain full control over airflow and ceramic heat retention. The grill includes a side shelf and Blaze Red finish. It suits smokers who want a standalone unit rather than an add-on. You pay for the entire structure, including the heavy ceramic body. The BMMXBI stone is lighter and fits into your current setup. Pick the grill if you need a new primary outdoor cooker. Stick with the BMMXBI if you already own a compatible Big Joe model.

MeWeBlue 36-Inch Magnetic Wind Guards

The MeWeBlue 36-Inch Magnetic Wind Guards serve a different purpose entirely. They are stainless steel shields for Blackstone griddles, not ceramic stones for kamados. The guards measure 16.9 inches in length and weigh 1.49 pounds. They protect your griddle from wind while adding minimal bulk. This product does not help with pizza baking or indirect heat in a kamado. You would choose this for outdoor griddle cooking in windy conditions. The BMMXBI stone is for heat deflection and moisture retention in ceramic grills. There is no overlap in function or compatibility. Select the wind guards if you own a large Blackstone unit. Ignore this item if you are looking for kamado accessories or pizza stones.

Pit Boss 4-Burner Portable Lift-Off Propane Griddle

The Pit Boss 4-Burner Portable Propane Griddle is a gas-powered cooking surface. It measures 63 inches long and 37 inches high. This unit uses propane fuel, unlike the charcoal-dependent kamado accessories. You get a large cooking area with separate burner control. It is designed for high-heat portable outdoor grilling and easy cleanup. The BMMXBI stone is a passive ceramic component for indirect cooking. This griddle is an active heat source with a hard cover included. Choose the Pit Boss if you need portable power and versatile cooking options. The BMMXBI stone is for users who already have a kamado grill. These products serve different fuel types and cooking styles. You cannot use the griddle as a heat deflector for pizza.

Onlyfire 18-Inch Stainless Steel Cooking Grate System

The Onlyfire 18-Inch Stainless Steel Cooking Grate System expands capacity on 18-inch Kamado Joe Classic grills. It weighs 14.2 pounds and is made of stainless steel. This system provides dedicated indirect heat zones for pizzas and vegetables. It is designed for Classic Joe models, not the Big Joe series. You get a robust solution for cooking large roasts or expanding your cooking space. The BMMXBI stone is a half-moon ceramic deflector for Big Joe grills. The Onlyfire grate is a metal system for a different grill size. Choose the grate if you own a Classic Joe and need more indirect space. The BMMXBI stone fits Big Joe I, II, and III models. These items are not interchangeable due to size and material differences.

COMVIEE 20-Inch Cordierite Heat Deflector Plates

The COMVIEE 20-Inch Cordierite Heat Deflector Plates are a direct alternative for Big Joe owners. It fits Kamado Joe Big Joe I, II, and III models. The size is 20 inches, slightly larger than the BMMXBI’s 19.8-inch diameter. This deflector provides reliable indirect heat for baking or roasting. You get a cordierite material option instead of the standard ceramic. The COMVIEE plate lacks specific weight and color data in the provided specs. It serves the same function of preventing burnt bottoms and retaining heat. Choose this if you prefer cordierite or need a slightly larger footprint. The BMMXBI stone is green and weighs 7.6 pounds. Both products offer indirect cooking solutions for compatible kamado grills. Verify your grill dimensions before selecting either option.
