Wonderboard vs. Easyboard vs. Hardibacker
I'm building a steam shower and had planned on using Kerdi over Wonderboard for the walls and ceiling.
The same manufacturer of Wonderboard also makes Easyboard, which they claim performs the same, but weighs a lot less.
Is there any drawback to using the Easyboard? How about Wonder on the walls and Easy on just the ceiling (to ease installation)?
Any preference for either of these or Hardibacker?
Thanks in advance...
