A traditional sauna is the dry-heat-and-rocks sauna, the original recovery ritual. The heat source is a sauna heater filled with stones; pour water on the stones and the room fills with soft, breathable steam. You choose dry heat, steam, or both in the same session. At Seven Seas, every traditional sauna in the lineup is a Tylö cabin from one of three collections, the indoor Halmstad™ Collection, the outdoor Lulea™ Collection, or the premium-aspen Reflection™ Collection, paired with a Tylö heater built around IntelliAir™ heat management and ThermoSafe™ touch-safe siding.
