Bathroom walls are a little out of wack... need a shower curtain rod. It needs to be either L-shaped, or round because there is no back wall to the shower.

Tried to mount an L-shaped one, but it isn't flush against the wall.

Should I try a round clawfoot style one and suspend it from joists in the ceiling?

Where can I find a round shower curtain rod for less than several hundred dollars?

Thanks!
