The Honka 345 is the largest cabin in the range: 3.44 m long, built from 45 mm log, and partitioned into a hot room and a separate changing room. Two rooms, one building The 3.44 m length splits into a 2.0 m hot room and a 1.3 m changing room. That partition is what makes this cabin work for a group: the changing side stays cool, so the hot room stays hot when people come and go in rounds. It also keeps the heated volume sensible. Heat the whole 3.44 m shell and you would be looking at a much larger heater; heat only the hot room and it is around 8.6 m³ — a size a normal heater handles properly, and comfortably inside what off-grid gas will serve. 45 mm log walls sit between the 42 mm panel cabins and the 70 mm Honka 200 — more thermal mass than a panel build, without the weight and cost of full solid log. Specification Capacity 4–6 people External size 3435 × 2490 mm Layout 2.0 m hot room plus 1.3 m changing room Heated volume approx. 8.6 m³ Walls 45 mm log Weight approx. 1100 kg What's in the box Everything structural. No hidden extras to buy before you can build it: Pre-cut, numbered 45 mm log walls Sauna benches Doors and glazing Partition wall Roof covering Floor and foundation beams Complete fixing kit Ventilation grids Step-by-step assembly instructions 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. The partition is what makes gas work on a building this long. At around 8.6 m³ the heated room sits inside the 8.1 kW envelope — heating the full 3.44 m shell would not. 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 on a cabin this size Adds the Njord heat shield and the Halo guard rail. The heat shield cuts the required clearance to combustible timber from 200 mm to 50 mm. The guard rail stops anyone brushing against the hot stones. Without safety pack Heater and stone cage only. Suits an install where clearance is generous and the sauna is for your own use. Every gas option includes the heater, the Orbis stone cage, and our fitting and commissioning. See the full gas heater range → Or choose electric or wood-fired above Electric — a Harvia heater with a full stone load for soft, steady löyly, integrated controls and a 2-year warranty. At 8.6 m³ take the 8 kW. Needs a dedicated circuit installed by a qualified electrician; budget £400–£1,200 for a garden supply on top of the heater. Wood-fired — a Harvia M-series stove. No electrics at all, a real fire, and the traditional way to run a cabin like this. We fit the flue on installation day. If you are in a smoke control area, check the model against DEFRA's exempt appliance register first — see our smoke control area guide. 2-year warranty Two years on the structure and on the heater, whichever heat source you choose. Covers manufacturing defects and workmanship. Where to put it A cabin like this is a building, not a piece of garden furniture, so it is worth thinking about placement before delivery day rather than after. Orientation. Point the glazing at whatever you actually want to look at — and preferably away from a neighbour's windows. South-facing glass gains useful warmth in winter but can make the room uncomfortably bright on a summer evening; west-facing catches the sunset, which for most people is when a sau
