Cement Board over Greenboard
Hey everyone, I am a new member here and also a first time home buyer. I took on quite the project about a year ago and plan to make a blog about my home remodeling experience. Enough with that though... Here is my dilemma. I am remodeling a bathroom and installed green board against the studs behind the shower tub. I have not decided if I want to tile or use a surround for the shower. After doing some research I have found that I should use cement board as the backing for both tile or a surround. Will I be ok to place the cement board over the green board and then tile/surround?

There is no need for tile board behind a glued on surround.
And there's nothing to gained by using it.
The surround is water proof, tile board is not.
For a far better look, longer lasting, at least three times as thick go with a nail on surround not a glued on.
It gets mounted directly to the studs and green board covers over the flanges.

After doing some searching I plan to tile the surround. The tub is already secured with the green board attached to the studs. My former father in law is the one who was running the show and thought that was the correct way to do it. What if I leave the green board, attach something like a Kerdi membrane, apply cement board over that, and then tile on the cement board? Will this work?

You will have wall/tub convergence problems if you don't.
