Quite enjoyed the writing and it’s a fun topic to think about.
Would doing a daily “submarine shower” [0] be the best strategy here for maximising cleanliness? This would be use fifteen seconds with water on to get as wet as possible all over, turn water off and apply soap and shampoo, then water on for the last 15 seconds. (Note I’ve never actually tried this so ymmv)
Those are generally known as "Navy showers," as opposed to "Hollywood showers."
(In one scene in The Hunt for Red October the sonarman Jones aboard the USS Dallas was told to take a Hollywood shower when he went off-watch as a reward for having detected and tracked the Red October.)
We used to do that as a way to conserve our minimal hot water, and while I can't say I enjoyed it per se, it was more satisfying to have a real blast of water when you could, than just dribbling it out at a paltry rate. And you were able to get clean.
