Kuuma Nature SaunaBarretta, Tasmania

Only a few things can make a sauna cooler (pun very much intended); a dip in the Tasman Sea off a bespoke pontoon boat is definitely one of them.

This sauna cruiser was custom-built to be the best damn sweat you’ve ever had, taking the sauna experience to new heights by setting sail to various open water locations in the Northwest Bay of Southern Tasmania.

There’s one wood-fired sauna on board and it’s been carefully designed to maximise your epic surroundings with large, glazed windows, so you can see the Tasmanian landscape clearly (you might be perspiring but the windows won’t be) and direct access to the chilly waters of Snug Beach, Coningham Beach and Howden upon anchoring.

Kuuma—a literal and metaphorical embodiment of ‘warmth’—encourages eager sauna-goers to disconnect from everyday life for the duration of their experience in order to rejuvenate their mind and body. If you’re sceptical, don’t be. Tasmania’s southern waters are cold. Like, 9 degrees cold or, ‘I can’t feel my toes cold’. So you’ll definitely feel alive and ready for anything after taking a dip.

There’s a skipper on board so you don’t have to worry about any technical stuff (phew), and two different session options—going communal or hiring it out for your own private use. Kuuma even offers sunrise saunas in case you’ve ever thought about plunging into freezing water at 6 am on a Tuesday morning.
