A group of friends in Joensuu, Finland built this awesome sauna raft back in 2012. In Finnish it’s known as a Saunalauttaand you can find several other DIY builds online. This particular homemade raft features multiple hammocks, multi-level decks, a tower and of course a fully functional sauna! Pictures on their Facebook page show them lounging on the raft with friends, using the second level deck as a diving platform and even grilling food on a portable bbq.(via: twistedsifter)
