Sauna, shower and shelter in one building. The Isle 300 puts a proper outdoor shower behind a slatted privacy screen, a covered terrace to stand in while you cool down, and a glass-fronted sauna room — so the full hot-cold-rest cycle happens without going back indoors. That is the difference between a sauna you use in July and one you use in February. The screen takes the wind off, the roof keeps the rain off, and the shower is two steps from the door rather than across a wet lawn. Built from 70 mm solid logs and stained black, it is the most substantial cabin in our Estonian range — 950 kg of timber before a heater goes in it. Why 70 mm logs matter Most garden saunas are built from 42 mm boards. The Isle 300 uses 70 mm interlocking logs — two-thirds thicker, and a different kind of structure. Solid log walls hold heat as thermal mass rather than just resisting its escape: the building warms through, then radiates back. It is why traditional Nordic saunas were built this way, and why this one holds temperature after the heater cycles off. It also means the cabin feels solid. There is no flex, no drumming in the wind, and no sense of a panel building.

We can advise on what is needed. Run it on gas — no electrician, no cable across the garden This is the option almost nobody else offers, and for a lot of gardens it is the one that makes a sauna possible at all. A FinSteam gas heater runs on a standard propane bottle — the same sort you would use for a patio heater or a barbecue. No armoured cable, no trench across the lawn, no electrician quote you had not budgeted for. If your garden has no power at the far end, this is how you still get a sauna there. Pick a gas option above and we fit the flue and commission the heater on installation day. You do not need to arrange anything with anyone. Which gas option? Botnia 81 Our standard 8.1 kW gas heater. Everything you need to run the sauna. Aurora 81 The premium version of the same 8.1 kW heater — better finish and detailing. And then: safety pack, or without? With safety packrecommended Adds the Njord heat shield and the Halo guard rail. The heat shield lets the heater sit closer to the timber wall; the guard rail stops anyone brushing against the hot stones. If you have children, guests, or you are renting the sauna out, choose this one. Without safety pack Heater and stone cage only. Suits a private install where clearance is not tight. Every gas option includes the heater, the Orbis stone cage, and our fitting and commissioning. See the full gas heater range → Or choose an electric heater The Isle 300 takes a wall-mounted heater in the sauna room, which keeps the bench space clear. Our Harvia Wall is black steel with a full 20 kg stone capacity for softer, steadier löyly, integrated controls and a 2-year warranty — and black suits the stained exterior. Harvia Wall 6 kW Rated 5–8 m³ — the sensible default for this sauna room. Harvia Wall 8 kW Rated 7–12 m³. Faster to temperature, and worth it if the garden is exposed or you want regular winter use
