Reuse shower curtain
I have recently had a plastic shower curtain (made of non-washable plastic) with motif. Over time, the curtain became quite disgusting (brown / gummy) despite regular cleaning at the bottom. Now I have a new (washable ^^) curtain and have used the old even more: I've cut out the motives (so that the disgusting edge is gone) and stuck them with double-sided tape on the bathroom tiles. Since I am absolutely no crafting person, I was always too much trouble with windowcolor and the like, and so I embellished the ugly tiles :)
These plastic shower curtains are not expensive in the other, they are available with all sorts of motives, so you can beautify his tiles so cheap, if you do not have just a screened shower curtain lying around.
