The Agrippabad was built in the 1950s and modernised between 1998 and 2000. After 23 years of operation, it is now due for another modernisation and redesign: the sauna and fitness area are to be redesigned in line with contemporary requirements and adapted to current functional and technical demands. In the interests of sustainability, the concept includes largely preserving the existing building fabrics. The technical infrastructure will also be modernised and updated in terms of energy efficiency. The construction work is scheduled to start at the beginning of 2025 and will take place while the swimming pool and administrative areas remain in operation.
