There’s nothing quite so invigorating as stepping out of a hot sauna and jumping into brisk waters. Unless, of course, the sauna happens to be a fully motorized vessel traveling around those cold waters. A successfully funded Kickstarter project by goCstudio, the floating sauna traverses both Lake Union and Lake Washington in Seattle. Guests, who include those who built it and those who backed it, can steam with a 200-degree view before hopping into the surrounding water. The sauna will keep at it year round, and the makers plan on introducing programming to let more of the community on board.
