When I went into space for the first time (that was to Planet Pzzxamix to investigate Trebor Snosrap) I was nervous about the whole toilet thing. Extra anxious and shy about such matters, I had envisaged I would spend most flights with all relevant sphincters tightly clenched until the journey ended and I could find a proper toilet.
How relieved I was (in more ways than one) to discover the Space SaniDroid. A sort of auto-loo that allowed you to go in total privacy even with someone else effectively standing right beside you. Shielding you from all potentially embarrassing noises and odours (whether the producer of such or recipient) the SaniDroid was every nervous ‘toileter’s’ relief station.
Of course, everything happens so much more naturally on a spaceship in the 23rd Century where artificial gravity has removed the weightlessness problems associated with excretion. So the SaniDroid has no need to worry about airflows, essential for early space travelers to ‘go’ safely.
The only possible problem with a SaniDroid is linked to unlikely power failure. That has happened to me once. All the lights went out and the body permeable door to the SaniDroid disappeared leaving me potentially visible to everyone whilst engaged in duties on my throne.
