Portable laundry drying/bath house and mini/portable Rocket stove for winter

Hi all. I'm new to the site. I hope this is the right place to post.

I want to build a 6x6 shower room/drying room for cloths during the winter. I live in a toy hauler travel trailer. So I want to make the bath house easy asimbeling/disasimbeling. I need it to with stand snow. I'm thinking of making it out of the fome insulation bard and pvc for framing. I also have car port frame left over. I might need to use the carport parts. Any suggestions ?

And for the rocket stove I'm going to make this https://permies.com/t/110574/Mini-rocket-stove-wheels-hot Would this work for a space heater ? Or should I make it out of diferant materials for a space heater ?
I also saw a build that used radiators from a car.    I might use a ice chest as a water tank. I could also just heat a few pots of water. What would be better and/or safer ?

Hi Kenneth. First off ... welcome to permies!

I'm sure the rocket stove experts will be along to help you shortly but in the meantime I've added this thread to the natural building thread. I think they might have some suggestions on something better than foam. Enjoy the permies adventure!

Bath house:
I'm going to make this    Just with 10-20 R insulation and maybe some framing(pvc or car port parts) that is easy disassembly. I need it to handel over night snow fall.

roket stove:
I'm going to put it on a piece of ply wood or thickly laminated particale board type of wood with handles to be slightly mobile. I have a part of a 55 drum and some tin sheeting to make the outside shield. Or I can cut a propain taink(cant realy afor to do this) its not the small one but the medium(8lb ?). Does it mater what material I make the burn chamber, heat riser and the gray areas in my picture with ? Perlite/cement, fire brick, cob and ducting that I can find at hardware store's is the materials I can get. I'l be j b welding the tin to the 55 gal drum. Jb weld can handle up to 500 F. Please fill free to edit any of my picture to further explain  ;)
