Steam & Oak Timo 320 Sauna Cabin — 4–6 Person with Changing Room and Porch - Pitched roof / 70 mm / Gas — Aurora 81 with safety pack
The Timo 320 is a two-room sauna cabin: a changing room on one side, a proper sauna room on the other, and a covered porch across the front. 3.2 × 2.0 m on the ground. Choose 50 mm or 70 mm walls, and a pitched or flat roof. Two rooms, and an insulated sauna roof You come in through an outer door into the changing room, then through a bronze glass door into the sauna itself. That partition is what keeps the hot room hot when people come and go — the thing a single-room cabin cannot do. The detail we would draw your attention to: the sauna section has an insulated roof element built in — 12 mm boards, 50 mm ISOVER insulation, 12 mm boards. Most garden saunas at this price have a boarded roof and nothing else. Heat rises, so an uninsulated roof is where it leaves; this is the single biggest reason one cabin holds temperature and another does not. Two double-glazed windows (120 × 91 cm and 100 × 60 cm) keep both rooms light. Specification Capacity 4–6 people External size 3200 × 2020 mm (6.46 m²) Layout Changing room, sauna room and covered porch Heated volume approx. 12.5 m³ Walls 50 mm or 70 mm — your choice above Wall height 2210 mm Ridge height 2800 mm pitched / 2530 mm flat Roof boards 19 mm, with an insulated element over the sauna Floor 26 mm boards Outer door 800 × 2010 mm Sauna door 700 × 1900 mm bronze glass Windows 120 × 91 cm and 100 × 60 cm, double glazed Roof covering Not included — ask us and we will quote shingles What's in the box Everything structural, including the parts most suppliers charge extra for: Pre-cut, numbered log walls Sauna benches Outer door and bronze glass sauna door Double-glazed windows Insulated roof element over the sauna section 26 mm floor boards and 19 mm roof boards Foundation beams Complete fixing kit Ventilation grids Step-by-step assembly instructions One thing that is not included: the roof covering. The manufacturer supplies the roof boards and the insulated sauna element, but shingles or felt are a separate item. Tell us when you order and we will quote it with the build rather than leave you to find it. 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. At around 12.5 m³ this is near the top of what a single 8.1 kW gas heater serves well. It works, and it is the largest cabin we will fit gas to — but if you want the room hot fast from cold in mid-winter, the electric 8 kW is the easier answer. 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 if children or guests use it 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 12.5 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 Orientation. Point the glazing at what you want to look at, and away from a neighbour's windows. West-facing catches the evening, which is when a sauna actually gets used. Clearance. Leave at least 300 mm behind and to the sides for air to circulate and for maintenance access. Timber boxed tight against a fence stays damp. Planning permission. Most garden saunas fall under permitted development, but there are limits on size, height and proximity to boundaries. Our planning permission guide covers it. Which heat source? Electric Set-and-forget, thermostat controlled, no fire to tend. Needs a dedicated circuit and an electrician —
