The culture of taking a bath in Japan is totally different from the rest of the world. First, you need to take a shower and wash your body well. Only after doing this, can you dip your body into the bathtub. If the plumbing is new, then, as a rule, it’s controlled with the help of a special panel. You don’t need to rotate the tap and adjust the water temperature — all you need to do is turn on the panel and indicate the necessary temperature on it. The water will come through a special drain.

Using the same electronic system, it is possible to redirect used water to the washing machine or to the kitchen sink. Since Japanese people wash before taking a bath, the water after bath procedures remains clean and suitable for second-time use.
