Sätrabastun is a wood-fired public sauna on a raft at Sätrastrandsbadet in Skärholmen, owned by the district and run by volunteer hosts from Sätrabastuns Skötselförening. There is no booking and no membership: visitors pay 40 SEK by Swish at the door and take a queue ticket when it is full. Regular sessions are mixed on Fridays 17–20, women on Saturdays 13–16 and men on Sundays 13–16. It holds 12, and bathers cover up with swimwear, a towel or a sauna kilt.
