building outdoor sauna

[saltwater cowboy]

Hey Guys,
plan on building an outdoor sauna in the near future. Got a wood stove already( thanks Alberta diver) now looking for what type to build. Me and a friend built a stick built one for him and he insulated and lined it with reflective foil and deck cedar. Tried it Friday night and it worked great. 165 degrees F and a roll in the snow at -20.
Thinking I would like something to be more rustic like a log cabin. Anyone have any ideas?
I think square cedar logs would be great with a green metal roof. Anyone know where to get those logs and prices or any other type of decent priced logs ?
PS, it is amazing how good beer goes down in a wood fire sauna !!!
