shower membrane

I live in Florida. I'm replacing my walk in shower. Everything I read or see says to use a type of membrane over the Durock, whether its Durock or Kerdi membrane or others?Is this over kill from the way we have always tiled, right on to the Durock?? Will the humidity in Florida be a down side to using a membrane?Maybe sealing the wall too much??Thanks

No -- to all 3.
Durock material isn't water proof --- when it does get wet it just won't inhibit mold growth compared to gypsum based boards --- even green board.
Contrary to popular belief, tile and grout joints (even sealed grout joints) are not waterproof. The Kerdi and similar membrances provide a leak proof watertight barrier to prevent mold and moisture issues behind the tile.

Re: shower membrane

Where are you using the membrane? The thick plastic membrane is used to pour a shower pan, but is not used in the walls. You don't need any kind of moisture barrier on the floor if you are installing a premade shower pan.
