“I ripped out my flushing toilets in both of my bathrooms and made “Humanure” ones. For just pee, I made this. It has a ping pong ball that was decorated by my daughter. It’s purpose is to stop the stink of the pee coming up from the bucket. It moves out of the way and lets the pee down and then reseals itself. Plus the guys get to pee on a face..they seem to like aiming at stuff. I suppose a photo of an ex would be cute too..or your favorite hated person. I keep a pitcher of water on a shelf next to it for the user to wash down the funnel afterwards.
