Common Ground Wellness Cooperative sits in Portland's Concordia neighborhood, a healing center built around a simple soak-and-sauna routine plus a short menu of wellness treatments. The outdoor courtyard holds a salt-water hot pool, a dry cedar sauna, and a cold shower, all under a clothing-optional policy.
The bathhouse is open daily from 10 a.m. to 10 p.m., with one exception: Wednesdays it doesn't open until 3 p.m. Quiet hours are built into the schedule too, running from 10 to 11 a.m. and again from 9 to 10 p.m. every night, so soaking at those times means keeping conversation to a minimum.
A basic soak-and-sauna pass runs $18 for 30 minutes and scales up to $48 for two hours, with members paying a few dollars less at every tier. Towels aren't included but can be rented for $2.50. Beyond the pool and sauna, the cooperative offers five wellness services - bodywork-style sessions ranging from 30 to 120 minutes - priced separately and also discounted for members.
As the name suggests, this is a cooperative business rather than a typical day spa chain. Walk-ins are welcome, but regulars who sign up for membership get ongoing discounts on both the soak-and-sauna passes and the treatment menu, which is how the place structures its pricing around repeat visits rather than one-off luxury.
