About Stu Brattøra
The operator says the saunas look out over the fjord. Visits are self-service: about 30 minutes before the session a text message brings the code for the door lock, and you let yourself in. Stu began with a single sauna, built by hand inside a Second World War bunker at Østmarkneset, which the company calls Trondheim's first publicly available sauna. The company traded as Bartstua before taking the name Stu.
