The image shows an indoor hot tub in a room with tiled walls and flooring. The hot tub is made of stone and has a small waterfall in the center. There are two windows on the right side of the tub, one on the left side, and a door on the top right corner. On the wall, there is a sign with Japanese text and a red triangle. The room appears to be dimly lit, with a few lights visible in the background.
