Specs

This is where a barrel sauna stops being a hot box and starts being a small building. The Saaren 330 is divided into two rooms with a glass door between them: a proper hot room at the far end, and a changing room in front of it. Add the covered terrace at the entrance and you have three distinct spaces in 3.3 metres. The difference that makes is practical rather than luxurious. Somewhere to leave clothes and towels that is not the hot room. Somewhere to sit and cool down that is not the lawn. A door between the heat and everything else, so the hot room stays hot when someone comes and goes. Anyone who has used a single-room barrel in a British February will know exactly why that matters. Spruce or thermowood — your choice Nordic spruce is the traditional barrel timber: pale, clean-grained, and the reason a new barrel sauna looks the way it does. It is the more affordable build, and it needs treating and re-treating to stay looking new outdoors. Thermowood is timber kiln-treated at 180–220°C in a low-oxygen chamber. That is not a surface coating. It changes the wood itself, closing the cells so it absorbs far less moisture — which is what stops outdoor timber cupping, twisting and splitting through a British winter. No chemical preservatives are involved. It arrives a deep honey-brown and weathers to a stable silver. Choose your timber above. The benches follow the shell: alder with spruce, thermo-aspen with thermowood.

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 go wood-fired — the traditio
