A calcium-led sodium chloride spring with sulfate adding a quiet, settled body — the certificate prints it as a Ca·Na−Cl·SO₄ blend. The wellhead is hot (49.2 °C) and cooled to a comfortable 42 °C at the bath, while pH 8.7 puts it firmly in the alkaline range with the slippery 'beauty-water' feel that locals associate with smoother skin. Dissolved solids land at 5,423 mg/kg — moderately mineralized, enough to leave a faint salty tang on the lips and a thin mineral film as you towel off. The bath is served straight from the source: no dilution, no reheating, no recirculation, only a chlorine-based disinfection step kept in for hygiene.
