We stayed at a few tea houses that had en-suite bathrooms (the joy!), but for the most part, the bathrooms were shared with the floor. This meant a few things. One, when you have to go to the bathroom in the middle of the night (and you will . . . a lot), getting out of your sleeping bag, wrapping yourself in a jacket, and putting shoes on to walk down the hall in the freezing cold really sucks. Two, you have to rummage around your room to find toilet paper to bring with you because they most likely won't have any. And three, you'll probably have to squat because the toilet itself is either just a hole in the ground or it's a regular toilet that's extremely dirty.
