Wet Bath Shower Curtain

I have a Northern Lite 10.2 RD with a wet bath. I just purchased it, but it did not come with a shower curtain. I picked one up from Walmart (72 inches long), but it is huge and takes up a ton of space. I don't think a regular sized one should be in there. I search the forums and saw some interesting mods, however, I want to simply install a shower curtain that works, and decide later on maybe modding it. Any help is appreciated.
