I spent some time contemplating the analog of a shower or a bath and generally washing oneself and how that would look in a zero gravity based environment.
My favorite idea is "water" injected into a contained environment to produce a particular pressure and or flow setting with a scuba type hose for breathing. All liquid is evacuated through the base and an air jet helps produce a drying effect plus clear out the capsule before exiting. The same water is recycled as much as possible after a filtering desalinization and any chemicals used for the washing process would be closely matched with the recycling process. I toyed with the idea of multiple pods in a spindle rotating to simulate gravity but I'm not sure it's worth the effort since you can produce a type of pressure through controlling the liquid syrup injected into the limited space.
