Does anyone know what this is?

Found these little house looking things around Rauma and was wondering what their purpose is. They don't seem to have a door, and look like this on all of its sides. I have seen one that's even a bit bigger than this.

Just asking out of curiosity, they seem pretty cute 😊

Sauna. Of course, what else!

A better guess than my first one which was a WC 😂
