Our cabin in the woods will contain a non-standard bathroom. After years of RV use we are accustomed to the smallish cramped spaces usually allocated to bathrooms in all but the more luxurious RV's. Hence, our bathroom is going to be fairly barebones; a Sun-Mar composting toilet at one end and a shower pan installed in front of it, by the door. The cabin bathroom will actually be larger than that in the RV!! I think we'll be able to shower without elbowing the walls!
We want a shower curtain that can be circled around as in the RV to keep excess water from the door and the toilet.
I have found the source for a variety of curtain tracks, some are hand bendable to whatever curve is needed.
curtainfair.com is the place (http://www.curtainfair.com/shwrtrac/shower_curtain_tracks.htm).
They have a wide variety of tracks and curtains. Worth a look.
Lots of types there.
