Sagene Folkebad is a public bath at the top of Grünerløkka, completed in 1899, renovated with the City Antiquarian and reopened by the Oslo Sauna Association in spring 2025. Two saunas seat 42–44 people, with bucket showers, cold plunge pools and a 12.5 x 6 m pool open during many sessions. Thursday is a nude day; on every other day swimwear is required. Volunteer aufguss masters hold rituals every Tuesday at no extra cost, and a shared ticket costs NOK 150 for members and NOK 260 for others.
