off-grid indoor shower, no electricity

UPDATE: the plastic shower rings started to break, so I ordered split rings from mcmaster-carr (90905A658) and used them through both shower curtain holes instead of just one. So now instead of 12 rings for one side I only need 6, now it's a lot cleaner and these ones won't become brittle and snap on me https://imgur.com/a/YYCDjMv
