Steve posted some details and tips for constructing a simple bathroom in a shipping container cabin.
“The platform is constructed of 2″x6″ cedar boards with stainless steel screws holding it together. The vertical support boards are cut out along the back wall to make room for the plumbing, which runs from under the kitchen cabinets to the shower platform. The tub is a Behrens 35 gallon galvanized steel tub that I got from Amazon, of all places.”
