Experience relaxation in its most complete form – both inside and outside the sauna. The integrated terrace offers the perfect spot to enjoy a breath of fresh air between sessions, cool down gently, or simply sit back and unwind. Whether you want to relax with a cup of tea, enjoy the evening atmosphere, or chat with friends before entering the sauna again – the terrace extends your wellness experience beyond the cabin itself. This model combines comfort, functionality, and a touch of luxury, making it ideal for anyone who values a relaxing retreat right at home.
