Eurotherme Bad Ischl, Thermal spa complex in Bad Ischl, Austria

Eurotherme Bad Ischl is a spa and hotel complex whose core is the Kurmittelhaus, begun by the municipality in spring 1929 and opened on 28 June 1931 by Federal President Wilhelm Miklas. The listed building was extended in 1952 with an inhalation wing and in 1968 with a hydrotherapy wing, and a 1976 underground passage links it to the Hotel Royal, built with 112 rooms.

The modern thermal complex opened in 2008, continuing Bad Ischl's long history as a healing destination in the Salzkammergut region. The town had already gained recognition in the 1800s for its therapeutic properties.

The Physikarium treatment centre uses four substances found locally: salt, brine, sulphur and brine mud, applied mainly to respiratory complaints, the musculoskeletal system and burnout. The complex belongs to the EurothermenResorts brand of the OÖ Thermenholding, Upper Austria's largest tourism company, together with the baths in Bad Schallerbach and Bad Hall.

The complex stands next to Bad Ischl's railway station square, whose redesign in 2008 cost 1.3 million euros; a new underground car park built the same year serves the centre. The Hotel Royal, with 112 rooms, is linked to the bath house by an underground passage dating from 1976.

The 1931 Kurmittelhaus, now the core of the complex, is a protected monument; the four-star Hotel Royal opened in 1976 with 112 rooms and is linked to the baths by an underground passage built the same year. The Physikarium treats respiratory and musculoskeletal conditions and burnout using local salt, brine, sulphur and brine mud.
