Bathing indications
The facility publishes general bathing indications. These are general hot-spring references, not a guarantee of personal treatment effects.
District-wide figures such as 22.1°C, 230 L/min and 26.5 Mache units per kilogram are not facility-specific measurements and are not used as such. Tattoos, fake tattoos and tattoo stickers are prohibited.
