Blind (City Centre NR1)

I'm having a new bathroom fitted, and I'm after a blind. Doesn't have to be too special - I'm thinking of having made-to-measure blinds installed throughout, in the fullness of time - but for now I need something easy to fit, 87 cms wide, drop of 150 cms. More wouldn't be a problem, but no less. Grey ideally, but the colour is really not the issue - I just want to spare my neighbours' blushes. Anyone out there who can help?
