On Apollo missions, that lasted less than two weeks, astronauts used fuel cells for electricity and water. Combining hydrogen and oxygen. Any mission to Mars would require quite a few supply ships for these and other supplies. The international space station relies on solar cells for most if not all it's electricity. It seems to me a Mars mission would quickly be far enough from the Sun to make solar insufficient to keep a crew comfortable. I guess the only thing left is nuclear. But nuclear requires heavy shielding. So heavy, I doubt it is a viable choice just to get it into earth orbit. I don't think the ISS uses nuclear. Finally, the last I looked, NASA (or anybody) had not invented washing machines for space. They could use "current" washing machine technology but that would require hauling heavy detergent and bleach.
As the article shows, astronauts would not be very clean.
There's some science for Hotshoe.

Water on the Space Station | Science Mission Directorate
Rationing and recycling will be an essential part of life on the newly-populated International Space Station. In this article, the first of a series about the challenges of living in orbit, Science@NASA explores where the crew will get their water and how they will (re)use it.
