I have hollow stud partition walls with 12.5mm thick aquapanel plasterboard which is then tiled over with 10mm thick tiles on a bed of tile adhesive.
So we are looking at 25mm - 26mm thick "wall" before getting through to the cavity.
Given that this shower curtain is going to get dragged open and shut all the time, I don't want the wall fixings working loose.
Can anyone recommend a good quality STRONG cavity wall fixing that will accommodate the thickness of the tile as well as the thickness of the aquapanel that will hold up the shower curtain rail?
Wing type cavity fittings are out as I don't have a ceramic drill of sufficient diameter to make a hole large enough to push the wings through like these here: http://www.toolstation.com/shop/p27061 plus covering up the excessively large hole with the shower curtain rail is going to be impossible as its of this type of shower curtain:
