Waterproof blind for bathroom/shower

[bigbutsrus1]

We are thinking of putting a shower over our bath but the window and current blind will get soaked. Was thinking there may be a type of waterproof blind that fits in runners so no gap if you see what I mean! Anyone have any ideas? Bathroom tiny and no other way around it.

Do blinds that are sprung and in a cassette ( kind of like a velux blind ) and they do them with PVC instead of material - I'd probably advise speaking with them about your particular project - but it might work ! Good luck !!!
