A cubic sauna is a cubic sauna with right or rounded corners, known for its open space, spaciousness and good views. Large mirrored windows made of insulated glass panels provide privacy while offering unobstructed views of the surrounding landscape. This feature enhances people’s experience of nature while making the interior more spacious and airy. During the day, the large windows allow ample daylight to enter the sauna; at night, the warm lighting system in the room makes the sauna look very beautiful and comfortable.
