While we do not have private showers directly inside the sauna area, guests do have access to showers located in the Vasa Park restrooms. There is one shower available in each restroom, plus an additional shower in the family restroom. Many guests also enjoy cooling off with a refreshing dip in Lake Sammamish between sauna rounds - a core part of the Nordic sauna tradition and one of the most unique parts of the experience at Vihta Sauna.
