Float On (Portland): Sometimes things just click into place. Float On took only 152 days to go from a conversation over beers to the opening day of a 4-tank float center on Hawthorne Blvd. in Portland, OR. The largest float tank center on the West Coast. Our grand scheme is to give everyone the chance to float, as regularly as they care to. We offer some of the lowest rates in the country ($50 for 90-minutes), and have all sorts of programs to help people get in the tanks.
