My thought was to recess a Big Box Shower Pan down between Trailer Frame Members. Or, modify the Frame a bit as req'd. Make the Shower Pan top level and flush with the CT Floor. Or, keep it simple and set the Pan up on the Floor, un-recessed.
Make an insert of Cabinet-grade Ply that could drop in horizontally to create 'more' smooth Floor in the Pan when not in the Shower. A Porta Potty could sit on that surface, too.
Inside and outside, mount two 45 degree Holders used outside a House to hold small Flags. Or, use some alternate Hardware. For the Shower Curtain Rail, bend Conduit into a 3-sided U shape. Friction fit that Shower Rail, holding the Shower Curtain, into the 2 Flag holders only when Showering. Alternately, make a Shower Rail that hinges down to the CT Wall when not in use. Do the same thing outside the CT, and use an opaque Shower Curtain.
A thin Plastic FRP Panel on the Wall would waterproof this p/t Shower Stall. Hold the Shower Curtain to the Wall with a few Metal Discs sewn-in, and Magnets. Another type of Shower Curtain we have has little Suction Cups integral to it to hold to smooth Tile.
During our new House construction, I lined 3 Shower Walls w/heavy Painter's Plastic. I retained it with top Molding, and just a few Staples around the bottom.
A second opaque Curtain, or even a Pocket Door, could 'wall off' the p/t Bathroom only when in use. At other times, you would gain visual space Psychologically from the 'open', unused Shower area, and thus recycle Bathroom space. How space is always recycled in Japan made an impression on me when I went there on Biz.
