There is no insulation behind either, and that is the design rather than an economy. The mass of the timber is the insulation, which is how a traditional barrel works: it takes longer to bring up than an insulated cabin and it sheds heat faster once the fire is out. What you get in return is a cabin that behaves like a sauna rather than like a heated room, and a shape with no corners for heat to sit in.\u003c\/p\u003e\n\u003cp\u003eThe door opening measures 169 x 59cm. The door itself is timber as standard, and a tempered glass door is available at no extra cost if you ask when you order. Choose a full glass front and the glass door comes with it, because the door is part of that wall. The cabin weighs 650kg; add the heater, the stones and four adults and the loaded figure is close to a tonne, which is the number to design the base around rather than the cabin weight on its own.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThermo treated Scandinavian spruce only.\u003c\/strong\u003e This cabin is also built in untreated spruce and we do not offer it. Thermo treatment is kiln modification with heat and steam rather than chemicals; it raises dimensional stability and resistance to rot, which is what a timber cabin standing in a British garden through a wet January is actually up against. It weathers to silver grey under UV, a surface change rather than a structural one.\u003c\/p\u003e\n\u003ch3\u003eThe heater, and the only decision that matters\u003c\/h3\u003e\n\u003cp\u003eThree heaters, all Harvia, all supplied with split face stones.

It needs a dedicated circuit installed and certified by an electrician: 8kW at 230V is about 35 amps, nowhere near a 13A plug, and a room containing a sauna heater is a special location under Approved Document P, so the work is notifiable in England. That visit is a separate cost.

Four people sit on two 600mm benches facing each other across a 686mm walkway, and the half height window in the rear wall, which is what Panorama means on this cabin, puts the garden behind you rather than a blank wall.

The wall is a single 40mm stave with nothing behind it, so the room loses heat faster than a cabin with insulated walls and takes longer to reach temperature on a cold night. Harvia's own sizing rule adds half again to the room volume for uninsulated timber walls, which takes the 5.6 cubic metre room to 8.4, and that is why the heater in the price is 8kW rather than the 6kW a cabin this size would otherwise carry.
