Shower Head

[edition]

Hi,

I'm just re-doing our bathroom and I have bought a really heavy fixed shower head! Now my issue is that the wall mounted elbow that I am using has nothing to really mount to as the walls are so thin! It will just rest on the inner skin of the plasterboard for the other side of the wall. This leaves me having to support the arm from the nut on the other face i.e. the tiles side......

Anybody have any good ideas on how to rectify my issue? I'm thinking i'm going to have to put a board up the front under the tiles to stiffen it.......


Thanks for any help!
