Collapsible and folding shower

So I saw this video and it gave me the idea, I could do that with coroplast.

Supplies:

$79 shipped collapsible 3' x 3' utility tray/improvised shower pan

Expensive, I know, but there just isn't a comparable product out there I could find.

$64 for 3 corrugated plastic sheets/improvised folding shower stall

You can also use campaign signs, same material, and free. I called a plastics distributor about clear sheets and they're 3 times the price, so scratch that. I will update when I finish the project. Just imagine a shower stall made of sign material, folded and zip tied together that can fold flat.

$15 2 piece screw together shower drain


I will simply cut a hole in the middle of the tub, apply some plumbers putty, and screw the shower drain together, creating a seal.
