For those looking for high-design heating options for the colder months, these three outdoor saunas offer an escape in the comfort of your own backyard.

Tapping into the long-celebrated tradition of the Finnish sauna, architect Rodolfo Dordoni designed the Cabanon for Italy’s Effe to be a destination unto itself. Corrugated aluminum exterior walls (painted Orange, Moss or Cement) withstand even harsh climates, while the interiors are lined with heat-treated aspen wood in smooth or boiserie textures. Inspired by Le Corbusier’s cabin with the same name, the outdoor sauna comes in five versions (three with a deck, two without); practical touches like a hand-held shower and hooks for robes and towels enhance the experience.

Burg Giebichenstein University of Art and Design Halle students Emil Löber, Friedrich Gerlach and Sophia Reißenweber developed the award-winning Mobile Sauna prototype as a place where people can gather and relax on campus. Far from conventional, the microarchitecture is super lightweight and can be easily transported thanks to its clever wheelbarrow-inspired construction: The steel tube standing frame turns on an axis to become a drawbar to pull and move the unit. Translucent polycarbonate walls blur the divide between indoors and outdoors, three wooden benches accommodate up to five inside, and the external fire is fed waste wood from the German university’s model construction workshops.

Specializing in modern and sustainable prefab cabins and homes for both residential and hospitality settings, U.K.-based Koto recently released this flat-pack design for the outdoors. Made from quality eco-responsible timber with charred timber exterior cladding, the striking structure delivers a traditional sauna experience in lightweight panels that are easily assembled on site by a small team. All structural boards come precut, numbered and pre-finished, and include insulation, a vapour barrier and a breather membrane. With crisp, minimalist lines, the outdoor sauna is a true expression of the brand’s attention to detail and expert blending of Scandinavian and Japanese design principles.
