Building a New Shower What to Use??

tuchodi

I am going to build a new shower in a ensuite bathroom. I am going to use the Kerdi system so my question what kind of wall board should I use on the inside of the studs (drywall or plywood). Pros and Cons for both.

I'd use cement board. I always use cement board. I know Schulter shows drywall, but in case the installation gets a pin hole in the kerdi, I use cement board.
Plywood is totally inappropriate due to possibly warping, among other reasons. Other reason is that I personnally don't like it.

The reason I suggested plywood is that I have lots of 3/4" GOS that I was thinking of using. Do you think that it will warp as the Kerdi is supposed to be completely waterproff. I realise that anything can happen such as a hole in the membrane but if carfully installed it should be 100% waterproff.

I agree with Ron 100%--Cement board-

It's like an insurance policy--You hope you never need it but you'll be glad you do if something goes wrong.

You will have a lot of time and money sunk into this shower by the time you finish-

will the cost of a few sheets of durrock matter that much?

I do what I do because it works, not because I have an excess supply of a specific building item. You can do whatever you want to do, I don't really care.
I should, but I don't.

Thanks for the responses. OK you have convinced me even is you don't really care (Ron6519). I value everyones opinions thats what these forms are for. I was not really trying to save a lot of money just use material I had so it doesn't go to waste, will have to come up with another project for the plywood. Cement Board it is!!!!

Pulling teeth from a chicken easy.
Sometimes you need to just get their attention.

You sure have differant chickens than were we come from. Look at the teeth on that one bit right through that 3/4" plywood.
