A conscientious worker gets his nutrition from a IV bag, and has both a catheter and a colostomy bag so he does not get interrupted by pesky trips to the bathroom.
The silly toilet-in-a-box is not needed.
As an aside, years ago I was working at a company where the owner was absurdly cheap. The toilet seat in the office toilet developed a small crack. The fear was that it would finally fail while in the midst of taking a dump.
The boss was in favor of getting the most mileage he could from the old seat.
I decided to use my woodworking skills to solve this dilemma.
I went the the shipping department and got an old wood skid that was too broken up to be useful. I used three slats and some too long nails and glue to make a “toilet seat topper” that could rest on top of the soon-to-fail toilet seat.
By the end of the day the owner had seen it. The following day we had a new seat.
I should note that I dispensed with any rounding over or smoothing out operations. The lumber was simply cut to size.
The joinery was sort of a half lap design that left the surface on two levels. It took less than 10 minutes to construct.
