S-Klubi was founded in the late 1980s by students wanting their own sauna. In the early days, there was a lot of discussion but few activities. The logo was designed in 1983. They began holding social events like Lokajoulut in October 1983. By 1984, Jari Vaario was chair and their goal was to find and renovate a downtown sauna. After a year of fundraising efforts, they were able to conclude 1984 and Antti Ylä-Jääski was selected as the new chair for 1985.
