I wonder if you can dig a hole and set up one of these and bury it with 3 feet of soil on top.
Could be handy for an underground shelter.

I'm interested in the cost to see if it is a cost effective shelter. I could build a 24' x24' shelter with a four inch slab, eight inch block walls, and six inch reinforced concrete roof slab complete with rubber coating and a commercial steel 42 inch door and cement block lined chimney for under ten grand A drain and small septic and drainfield along with a masonry lined chimney could run another three grand.
I'd rather create a pyramid shaped reinforced concrete shelter myself with a central fireplace I could get a permit for a sauna
