Cedar ceiling in bathroom?
I want to install a cedar ceiling in my bathroom above the shower over the existing Sheetrock. Is there a vapor barrier needed or will i need any airspace between the ceder plank and the Sheetrock? I want planning on using any sealant on the wood. just tongue and groove planks and brad nail it up. Thanks for any help.

Cyprus,
No, you don't need an additional vapor barrier between the drywall and the cedar boards. However, I wouldn't use untreated cedar in that location. You'll get steam and splashing, and therefore there is the potential for mold and mildew.
Conscientious use of your bathroom exhaust fan every time you shower (and for 10 minutes afterwards) will help.
Remember to use stainless-steel fasteners. Ordinary fasteners will leave rust streaks.
