Who hasn’t heard of the famous Japanese toilets?
Not every toilet has this kind of panel right?
As most toilets already have, this one also has the option to flush two different quantities of water. That tap in the top lets you wash your hands after using the toilet, and at the same time using that water to flush the next time! It’s said that the Japanese people use a lot of water, so this is a really nice method to save water!
Oh, and another interesting point is that the toilet seat is warm in the Winter 😀
