Guss is Portland’s first river-front mobile sauna experience, offering social sauna sessions centered on heat, cold, breath, and stillness. The business welcomes gatherings such as birthdays, team outings, and winter dips with friends, with drop-in sessions open to guests ages 16 and up. Guss also donates 5% of all revenue to the Human Access Project, supporting efforts to keep the Willamette River clean, safe, and accessible for Portlanders.
