A floating hydrotherapy spa built on a restored 1943 US Navy workshop barge moored at Ship Point in the Inner Harbour, next to the Harbour Air seaplanes. Three saunas vary in temperature and look out over city or ocean; two take water on the rocks and one is dry. The free-flow circuit adds two cold pools, two hot mineral tubs and a salt-scrub shower. Guests must be 19 or older and reservations are highly recommended. Opens 8am Friday to Monday, 9am Tuesday to Thursday.
