I'm thinking of using drywall for the inside walls (and catheral

leave the windows open or the door).

How about that drywall for use in showers and around baths? Water
doesn't bother it at all.


That's an idea. How long can it withstand being wet? Or will it
just stay intact no matter what?


It's not waterproof, by any means. It's made with water resistant
resins and mildew reistant paper. It won't crumble as fast as regular
drywall, but it won't stand up to being constantly wet either.

I think we are talking about different stuff.

Probably. The OP mentioned "that drywall for use in showers and around
baths." As far as I know, he's referring to "green board" which is what I
described - drywall with waterproof resins and paper treated to resist
mildew.

You might be referring to "Wonder Board" (generically called "backer
board" around here), which is basically concrete with fiberglass mesh on
the surface. It's hard, durable and mostly impervious to water. However,
it's heavy, expensive (relative to drywall), and has a very coarse surface
that would need to be covered with something to make it smoother.

For a child's playhouse, I'd use plywood for durability, but then again, I
have 4 boys :-)
