Visits to a spa are indeed one of those few relaxing moments we enjoy in our busy urban lives. Take this spa in Bad Essence for one. A paradigm shift away from probably just about any spa you might’ve visited before, this one called the Sole Arena is a simple wooden construction, which on entering, lets users breathe in air with a touch of salt. Inspired by local history, the Sole Arena spa makes good use of the fact that Bad Essence is a place known for its thermal springs and salt production. The aerosols in the air help clear respiratory diseases, and the Sole Arena has users breathe in air laden heavy with salts!
