The Kaari 240 Terrace is the same 4.05 m oval shell as our Kaari 240 Panorama, in a simpler configuration: a covered open terrace at one end instead of an enclosed changing room, and a square window rather than the Kaari 240 Panorama's full-height round one. If you like the oval form but would rather sit outside under the roof than have a second enclosed room, this is the one. Construction follows the rest of the range: 42 mm side walls, thermo-aspen benches, stainless steel bands, and the heater on a dividing wall between the hot room and the terrace. The layout is the point The Kaari 240 Terrace splits its 4.05 m length in two: an enclosed hot room at one end, and a covered open terrace at the other, with the heater on the dividing wall. Heating the whole 4.05 m shell would mean roughly 15 m³ of air, which is why saunas of this length are often quoted with 12–18 kW heaters. Because only one end is enclosed, the heated room is around 7 m³: quick to temperature, steady once there, and comfortable on a sensibly sized heater. The covered terrace is the practical part. It is inside the footprint and under the same roof, with bench seating and a table, so the cooling-off half of the session happens out of the rain without adding a separate structure to the garden. Why thermowood matters here Specify the body in thermowood and it 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, and it weathers to a stable silver-brown rather than going grey and rough. On a curved building this matters more than on a square one. Every board in an oval shell is doing structural work as part of the curve, and timber that moves is timber that opens gaps. Thermowood is the reason the shape stays true. Specification Capacity 4–6 people in the hot room External size 4050 mm L × 2400 mm W × 2200 mm H Layout Hot room plus covered open terrace — heater on the divider Heated volume approx. 7 m³ (total shell approx. 15 m³) Side walls 42 mm thermowood Rear wall 28 mm thermowood Door 1650 × 590 mm Window 770 × 570 mm Benches Thermo-aspen — stays cool to the touch at temperature Roof Bitumen shingles — black, red, green or brown Bands Stainless steel Delivery Flat-packed on pallets — ask us for the exact crate list What's in the box Everything structural.

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 partitioned layout is what makes gas work on a building this size. At around 7 m³ the heated room sits comfortably inside the 8.1 kW envelope — a single-volume 15 m³ 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.
