How to Enjoy the Perfect Sauna
Heat Up the Sauna & Prepare Cold Bath
Before using the sauna, we need to prepare the cold bath (about 2 hours) and heat the sauna (about 1.5 hours). Since these two preparations can be done simultaneously, we recommend starting about 2 hours before your intended use for optimal comfort.
Prepare Your Body
Take a shower and remove all jewelry and accessories. Hydrate well before entering the sauna.
Enjoy the Sauna
Stay in the sauna for 10-15 minutes. Add water to the stones for löyly. Listen to your body and exit when you feel ready.
Cool Down & Relax
Step outside to the wooden deck for fresh air cooling. Relax on the lounge chairs and experience the perfect "totonou" state.
