Go wholly unconventional. Think of a doorless shower, the kind that has a little hallway of tile and you go around a corner and there’s the shower. Multiple streams of water all pointed at a reclining chair with a split saddle for a seat and something like stirrups to get your legs elevated enough. A little river of water running underneath which goes to what’s basically a toilet built in to the lowest point of the floor.

It would be like a spa where you get to completely let loose. And after you’re gone your family will be really confused by it, so bonus.

Admit it, this isn’t the craziest idea you’ve ever heard of. Crazier things exist already.
