And thankfully people don't pay too much attention.
It must be true, when you really think about it, that atoms in the water that you drink, have been through the digestive systems of other humans - and other living things. They've gone in one end and come out the other. I have an inkling that xkcd has even run a strip or a What If about it... But in space, in the Oort Cloud, needs really must, and out of necessity, people drink their own pee.
Recycling of basic, rather than processed resources, must be an absolute societal basic at the very edge of interstellar space. With the exception (probably) of cometary mining, there's no more water around unless you have alchemical processors - and those things don't run cheap.
I guess most places wouldn't begrudge thrillseekers and travellers some basic water rations (apart from despotic asteroids or criminal waystations); they might not include showers or baths as part of basic accommodation though. Going a step further, a simple bath might be considered a luxury - a spa retreat might be half a day just having a good soak.
If you have the rights or the firepower to defend a cometary ice body - or some other source of water - then you might be on to a winner economically... Or you might have painted a big target on yourself.
