I spent ages looking for a shower curtain rail for my bathroom. You see, we have a window at one end of the bath, meaning we couldn't have a regular rail that is suspended at both ends. I like alternatives, such as encircling shower rails (either square or circular), but as the bath does not stand away from the wall there was not enough room for one of those. I eventually found the shower rail above from Next, that is fixed at the tap end only.
The shower curtain hooks and curtain are from Restoration Hardware. The shower curtain is two-part, with a decorative banded sateen shower curtain that hangs outside the bath and a clear vinyl curtain liner on the inside to stop water leaking everywhere.
