In case you didn´t know how japanese showers work. You usually have a whole littler room for you, where you sit down on a little plastic stool with a mirror in front. There you can sit and splay around.
One of the nicest shower rooms I´ve seen so far was this one with a beautiful floor and a rock they build the house around. From the steam and the moist of all the people showering there fern and other little plants grow in there. A real pleasure to get clean in there!
