PRIVATE There's something that looks like a chair filled with water. Since you're mortal again you're going to need that quite a lot more than you're used to. Sit on that chair, do your business, and then push the silver lever down to replace the water. After you're done, wash your hands in the basin. There's a lever to turn on the water and some soap to rid your hands of germs. The water may get hot depending on how far left the handle is turned, so be mindful of that. If the water is hot enough, it could hurt to touch.
