Pure relaxation in an extravagant ambience

Relax and be revived

The BIORHYTHM PRIVATE EDITION sauna is the brainchild of designer and interior architect Nik Schweiger.

His concept of “Biorhythm – Modern Recreation” is reflected in every element of the sauna. He combines material, form and light into a holistic concept and uses organic forms and softly flowing transitions to ensure the sauna embraces the human body like no other.
