Correct use of moisture resistant Purple board in Bathroom?


You can't put Hardi over drywall. (Well I suppose you can) Why would you want to do that? The Hardi is not waterproof and will wick water through to the drywall over time.

I had some reasoning for this, but it's probably faulty.
Yes I'm somewhat sure it is. After all of the above.

Okay Mike, Jaz, I'm out of this one. Take it boys.

OK. you've got some folks confused. Here is what I think. Do the whole bathroom in moisture resistant drywall. It's a damp area prone to growing mold. MMR board is cheap insurance. Put the 5" piece at the bottom where it is mostly out of sight anyway behind a vanity, tub and toilet. Use Schluter Kerdi membrane in the shower area. Tile over it and forget about it.
