Morning all, I'm hoping for some advice, I need to install a thermostatic shower at the end of the bath (Pictured). At the moment it's plasterboard, I was thinking of replacing it with cement backer board but as the shower head and controls will be mounted to it I was wondering if cement board would be strong enough if the head or controls were knocked by somone. I thought maybe some sort of plastic sheeting instead such as nylon, acrylic etc would be more suitable, the bath surround will either be tiled or clad in bathroom paneling and there will be a glass shower panel attached to the studwork behind the new panel. Or would the cement board be strong enough on it's own? Any thoughts/advice on this please? Thanks Wayne.
