ah, Haven't seen it myself then
To answer your q about shower caddies, I have one that doesn't need screws to fix it to the wall. It's on a telescopic pole that you screw to tighten into place. Bit like a shower pole?
It was from Next so not too expensive. It goes from bath to ceiling and it's been in place for around 4 years now. No rust, no wear and tear and quite a lot of space for shampoo, cond, etc. Only thing it has trouble holding is the soap but thats cured by using shower gel instead ;-)
