Of course, everyone has his own idea of what a real bath should be. In this case, the picture shows a classic version of a log bath. It is clear that the main thing is the steam room, but the external design also matters. The remarkableness of this building is in the veranda. So already imagine how you can have a wonderful rest after the steam room.
Usually very little space is allocated for a bath, especially if the site is not large. After all, the steam room performs the main function in the bath, and the rest of the extension is just an addition to it.
But in this case, such an extension can serve as a separate resting place, like an ordinary gazebo or porch. So in any case, it is very convenient.
