About prices: Site never uses the word sauna or steam; it describes separate ladies' and gentlemen's 'heat and water facilities', open only in the hour before a booked massage, body treatment or facial (not with salon services, and not usable after treatment). Cheapest treatment shown is a 60-minute facial from $280. A bathing suit is required for the heat and water facilities.
