Sense of Self, known as SOS, is Melbourne's largest bathhouse and day spa, housed in a converted warehouse at 30-32 Easey Street in Collingwood. Founded in 2021 by Mary Minas and Freya Berwick, the venue brings together ancient bathing rituals and contemporary wellness thinking in a striking industrial setting. The ground-floor bathhouse features a large mineral magnesium pool heated to 39 degrees, cold plunge pools at 10-12 degrees, a Finnish sauna at 80 degrees, and a traditional Hammam steam room. Guests can explore self-led Hammam rituals combining Sud and Mud treatments for deep cleansing and care. The upper level houses a massage and mindfulness studio offering remedial, relaxation, and pregnancy massages alongside Gua Sha facials. Sense of Self has become a beloved fixture in the Collingwood community and a landmark destination for urban wellness seekers in Melbourne.
