42 inch corner oven slab dimensions

[Frankie125]

I know this must have been covered before, what should the foundation dimensions be to build a corner pompeii oven?

[UtahBeehiver]

Too general of question without knowing type and thickness of insulation, material of dome, material of outer covering. You can do a search for corner builds or look at the FB eplans as well.

All you need is to cut a sheet of cardboard out that is your chosen size. Add all external things like brick, insulation, and enclosure if doing one and you will have your required size. I believe fo my 40" oven i was at 70" x 70". I believe a 42 would have also fit that base. I was on the corner as well.
