Have you heard of a system for RV campers that lets the user take long showers using the same filtered water over & over? Has anyone heard of or used such a set up? Any recommendations?
Here’s some of what I’ve found so far. Loopz: https://hamwells.com/en/loopz/

Something to note us that most of these systems are severely undersized in RV installs and require constant maintenance to use. Even with “special” soaps the particulate load is much higher than even multiple 20in big blue filter is ready for with repeat use and the phosphate levels in the water can get crazy high super fast.
A full grey water treatment system could work, but sizing for 100-200 gallons a day is way larger than most people anticipate.
