Thermal Corvinus

Thermal Corvinus sits on a 14.7-hectare site on the edge of Veľký Meder, near the Hungarian border in southwestern Slovakia, and has drawn visitors since it opened to the public in 1974. Two geothermal wells, 327 meters apart, supply the resort: Well 1 taps zones between 1,626–1,675m and 1,720–1,791m and delivers water at 72°C with total mineralization of 1,098 mg/l and a pH of 7.46, dominated by sodium (301 mg/l) and bicarbonate (763 mg/l) with measurable fluoride and dissolved silicic acid; Well 2 draws from 1,073–1,438m at 56°C with a pH of 7.86 and slightly lower mineralization. The resulting sodium-bicarbonate water is used for joint, spine and muscular ailments across the resort's multiple pools.
