This is a picture of my friend's toilet (Nancy, France). There should be heater's in and out, toilet's in and out, and a basin's in and out. But, water in will be shared and water out are as well. Though, I don't understand how it becomes so complex. I have a impression that I could find easily such unnecessary complex things in France.. It is just my impression. Well, I experienced one of the train system in England was also unnecessary complex.
