Sauna Bath?

In this striking scene a man reaches out from the interior background to draw the woman inside with him.
The viewer is also brought into the act as they spy not only upon the encounter between the man and the woman,but also upon several more women in a third room that opens to the right, while the sense of public space is expanded even further to the outside world through the window on the left, where a harbor is visible.
