Spa Therme Blumau

Rogner Bad Blumau is a resort spa built around the Vulkania thermal spring, with the whole property designed by artist Friedensreich Hundertwasser and billed as the largest inhabitable work of art. Colorful hotel buildings with grass-topped roofs sit across a 420,000 m² site that includes more than 20,000 m² of outdoor lounging space, an 8,500 m² wellness area and over 3,000 m² of water surface, including thermal and outdoor pools.

The spa is set up for overnight guests rather than casual day visitors: access is for hotel guests only, and a therme visit needs to be reserved in advance through the online booking system, with a separate quota available for guests staying in Bad Blumau itself. Facilities on site include a restaurant and café, a relaxation lounge, outdoor baths and the thermal pool complex. The resort positions itself as family friendly as well as suited to couples looking for a quieter stay.

Room rates start at €147 per person per night, including half board with a regional breakfast that can be eaten in a bathrobe, valid through October 22, 2026. The property also runs a geothermal energy system dating back to the early 2000s, recently supplemented by a photovoltaic installation, in line with Hundertwasser's stated philosophy of living in harmony with nature. Treatments such as Hydrafacial skin care are also offered as an add-on to the wellness program. For exact opening hours or same-day access questions, it's best to call ahead or check the booking portal directly.
