Icosauna packed for travel and set up beside a campervan

A proper sauna that travels

Somewhere between a tent, a Platonic solid and an excellent sauna.

Icosauna packs small enough for a campervan or suitable car, assembles in about 15 minutes and turns a good campsite into a very good campsite.

The structure is a rigid icosahedron made from 25 wooden rods and 11 ASA hubs. In the centre hangs the flying dodecahedron: a stone heater carrying approximately 50 kg / 110 lb of sauna stones.

Dense löyly and condensation inside the Icosauna portable sauna

Built for löyly

Hot stones. Hot steam. Cool structure.

The suspended mass of hot stones produces dense, humid löyly. Steam rises into the upper part of the sauna and condensation runs across the clear cover. It gets wonderfully foggy in there.

It is not a dry little camping tent pretending to be a sauna. It likes water. A lot of it.

Suspended dodecahedron sauna stone heater inside Icosauna

The flying dodecahedron

Of course an icosahedral sauna needed a dodecahedral heater.

The flat-packed heater hangs from a chain in the centre of the structure and holds approximately 50 kg / 110 lb of sauna stones.

We recommend an 8 kW gas burner to preheat the stones from below: approximately 45 minutes in mild weather or around 60 minutes in cold weather.

Important: the burner is for preheating only. Keep the sauna ventilated while heating and switch the burner and gas supply completely off before anyone enters.

Icosauna icosahedron frame showing its triangulated wooden structure and ASA hubs

Seriously strong geometry

25 pieces of wood. Triangles all the way down.

An icosahedron is triangulated in every direction, making the frame remarkably rigid despite being lightweight and demountable.

The structure is strong enough for four grown men to hang from it at the same time. We know because that's the kind of product testing we believe in.

No floppy cube. No tent poles pretending to be architecture.

Portable freestanding Icosauna outdoor sauna beside water without guy lines or ground anchors

No guy lines. No ground anchors.

Freestanding means freestanding.

Approximately 50 kg / 110 lb of sauna stones hang low in the centre of the triangulated frame. No stakes to hammer into frozen ground. No ropes to trip over.

In a tornado, we recommend postponing the sauna.

Tested by actual humans

“I thought it was a bit absurd at first, but it’s honestly a beautiful piece of kit. It's stupid strong. It packs down well, sets up fast, and the steam is excellent.”

FAQ

Things sensible people ask before buying a geometric sauna.

Probably. The longest components are the wooden rods at 1500 mm / 59 in. Icosauna is designed for campervans and motorhomes and fits many cars with suitable cargo space or folded rear seats. No trailer required.

About 15 minutes. One person can assemble the 25 wooden rods and 11 hubs into the frame and fit the two-part cover without special tools.

No. Icosauna is a freestanding triangulated structure. Once loaded, approximately 50 kg / 110 lb of sauna stones hang low in the centre.

The kit includes the complete frame, two-part cover, dodecahedral stone heater and suspension/assembly hardware. You provide suitable sauna stones, a suitable high-output gas burner and cylinder, water and seating.

An 8 kW gas burner heats the suspended mass of stones from below. Expect approximately 45 minutes in mild weather and around 60 minutes in cold weather. The burner is for preheating only: keep the sauna ventilated while heating, then switch the burner and gas supply completely off before anyone enters.

Icosauna is portable, has no foundation and can be assembled or taken down in about 15 minutes. Rules for temporary structures vary by location, so check the regulations where you plan to use it.

For people who don't need another camping gadget

Build an icosahedron next to your campervan and take a sauna inside it.

This is the logical next step.
