shower caddy for sliding door

[ArriettyC]

Any good suggestions for shower storage of shampoo bottles etc? I don't really want to drill into my tiles, but perhaps I will have to! I have had the suction ones, that fall off with a massive crash in the middle of the night! And I have had an expandable chrome pole which soon became rather rusty! I looked at the Lakeland hanging one, but not sure how that would work with sliding doors ...
what do other people do?!

We have the suckers. I like the thrill of them crashing down in the middle of the night, scaring the bollocks off us all and potentially scratching our bath permanently :o

will watch and see what's suggested by less-self-destructive people who like their sanity and bathroom intact! :o

You can get ones that hang over the shower head fixing. There's always loads in tk max. Not tried one yet as we have a fixed head rather than a sliding rail so it looks like it might be a bit fat.
