I have a converted attic bedroom with a bathroom. I want to install a curtain rod, but one side of the rod has to connect to a sloped wall (the roof). What would be the best way to install a rod in this scenario?
Get a swivel shower rod flange like this:
or this :
It looks like they're available in a range of sizes and finishes so you should be able to find one you like.
At my parent's cottage, they had a similar situation. The tub comes out from the sloped wall, with the shower head on the opposite wall.
They put a corrugated translucent acrylic panel up, cut to fit under the sloped part of the wall, and framed using some PVC c-channel moulding all the way around (you can find all of this at most box stores). The panel is about half the length of the tub.
Then there is a normal (but short) shower rod and curtain up on the other half, which works out to be more or less the same height as a normal shower curtain. As I recall, it's about half the length of the tub (so 2.5') which is comfortable to get in and out of. Some caulking around all the moulding on the inside, and it actually works very well, and looks pretty decent.
Update: Was out there again this weekend, and remembered to take a pic. somewhat low quality as I just had my iPod:
