Water handling

The inn says its public baths, guest-room baths and washbasin hot water use 100% spring water, free-flowing without added water or heating and without recirculation. It does not publish a complete disinfection specification for every bath.

The inn's current official pages do not confirm a formal drinking-water permit or a daily drinking amount; do not treat its descriptions of drinking as instructions. Tattoo rules are unconfirmed.
