This is just my experience, but that experience includes travelling through some remote areas in less developed countries. Water to wash is usually the first upgrade on the tech tree- It’s unlocked right after you dig a hole in the ground. Grinding xp to get plumbing will make life nicer, but to start with you just need to gather enough resources for a bucket.
Added water infrastructure? My guy, the connection for the cistern is right there. The added infrastructure is literally a tee piece and the hose.
That is fair, though in places with unreliable water I doubt that using water to flush or a bidet would be the first priority.
