13.2" x 13.2" x 0.6" Square Cordierite Pizza Baking Stone Perfectly Compatible for Ooni Karu 12 Pizza Oven

This 0.4” thickness fits my new Ooni Volt 12 exactly like the standard stone that comes with the oven, and performs identically. Excellent choice, since it seems like even Ooni itself doesn’t sell a replacement stone on their site (as of today, at least).

Stone was a perfect fit for my ooni oven and worked well

Got this as a replacement for my Big Horn oven. The original didn’t last and it was very thin. This fits the oven flat with the opening even though it’s a little thicker and I cannot really tell any difference with the front of the oven. It heats up quickly for me. Saved the day.

My Ooni 12's pizza stone cracked in half when I tried to gently wash it in the sink. I got this a replacement. It is the same thickness and size and worked as well as Ooni. I have only used it once but will use it again tomorrow. Hopefully, it holds up better than the Ooni stone. Hopefully, my Poolish looks good tomorrow and my dough works out.

Fits koda 12 perfectlyBetter than original

Great quality and perfect replacement for Ooni 12 Koda. Recommend.

Fast service to get the replacement stone. Tried already and it works very well

The stone is half the thickness of the original Ooni stone. Might work well, but I didn't try it. Returned it based on simple logic, thicker stones hold more heat. This stone was 1/2 the thickness of the original Ooni stone so I'm "guessing" it won't hold the same amount of heat.
