Imperial Spas was one of the most modern facilities of its kind in the world at the time. For the first time, a unique system of transporting prepared tubs of peat by means of lifts and internal pavilions to the baths themselves was used.
In the period press it is even said that the baths "miraculously emerge from the floor and after bathing disappear again just as miraculously in the floor".
The entire operation was carried out in such a way that visitors were not disturbed by the smell of peat by the staff. The building is thus full of hidden floors, service areas and technical facilities that were hidden from the ordinary visitor.
