I think a good approach would be to have a stainless steel one,
with sufficient slope included, and using an end trough type drain
in it. I would make it of actual human usable size as well. I'd have
it installed in [under?] the floor with a liftup/foldup floor panel
covering it when not in use. You can install a surround type shower
curtain rod or track on the ceiling above the shower area. I don't
think it would be excessively costly as there is not that much material
involved and the fabrication of it should be straightforward.
While this is not what I described, this is another approach [great idea
to me] to the problem of providing a usable sized shower area in a 'smaller'
TT. Here is a link to a South African Off Road Caravan that has a novel
approach to providing a shower area with a molded in, low profile, shower
pan as a part of the floor. They use a SS chain bottom-weighted [within the hem]
shower curtain to keep the curtain within the shower pan perimeter lip.
