Click the PHG wetrooms link in my signature.. much better prices on Marmox boards..and easy to cut with a utility type knife.
Guys,
I hate to go against the grain, but i have to ask. I'm all for using the correct products, i agree ply is not a great substrate and both deano and Ed are correct in their recommendations.
However, from what the op posted i've taken this to be a stud wall built out into the room to create an enclosure space. So, with no "outside" influences (i.e no outside walls, rooms to effect any tempreture etc) would the following not be sufficient?
As long as the studwork is built well and there are plenty of regular fixings to a rigid frame. Insulate the cavity in the wall. This will keep tempreture consistant within the cavity and prevent any warping of the ply. If you then tanked the face of the ply, better yet the wall all the way round. Would the tanking not only waterproof the wall, provide a means of a de-coupler but also insult the ply from any heat transfer from using the shower?
I completely agree the ply shouldn't of been used in the first place, but, if the op really didn't want to take it out or if it was too much hassle. Do you think what i'm suggesting would be sufficient?

It may work it may not but removing and re doing now is a lot better than re doing the job after it is all finished. Just my opinion

Ok everyone. I think you have me convinced. I've pretty much got my head round taking the face off all of the fin wall and box frames that i've built and replacing them with backer board. Probably hardiebacker as i can just get it from B&Q. The wedi board sounds handy but i haven't seen any here in Northern Ireland. I'm usually a belt-and-braces type in my DIY so i'd rather do the job properly.
The only thing not done properly then will be the jointing tape at the back vertical corner. As i said, the back wall is already tiled so i wont'be able to re-apply the tape when i replace the ply side wall. I will however use silcone in the corner joint between the tiles so hopefully this will allow for any movement.
Some day this job will be done!
