This oven's not bad I guess. It's not as nice as a brick built oven. The pre-cast dome is fairly thin and doesn't hold heat well, so I have to keep a good fire going all the time. The upside to that is it heats up pretty fast. I can be at pizza temp in an hour or so, no problem. I use about 1 and a half of the large tupperware bins full of wood in a day. Because I work alone, I usually only make one pie at a time, but there's easily room for two. It's 36" inside diameter.
