{"product_id":"steam-oak-kaari-240-terrace-sauna-pod","title":"Steam \u0026 Oak Kaari 240 Terrace Sauna Pod — 4–6 Person with Covered Terrace","description":"\u003cp\u003eThe Kaari 240 Terrace is the same 4.05 m oval shell as our Kaari 240 Panorama, in a simpler configuration: a \u003cstrong\u003ecovered open terrace\u003c\/strong\u003e 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.\u003c\/p\u003e\n\n\u003cp\u003eConstruction follows the rest of the range: \u003cstrong\u003e42 mm side walls\u003c\/strong\u003e, thermo-aspen benches, stainless steel bands, and the heater on a dividing wall between the hot room and the terrace.\u003c\/p\u003e\n\n\u003ch3\u003eThe layout is the point\u003c\/h3\u003e\n\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003cp\u003eHeating the whole 4.05 m shell would mean roughly \u003cstrong\u003e15 m³\u003c\/strong\u003e 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 \u003cstrong\u003e7 m³\u003c\/strong\u003e: quick to temperature, steady once there, and comfortable on a sensibly sized heater.\u003c\/p\u003e\n\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch3\u003eWhy thermowood matters here\u003c\/h3\u003e\n\n\u003cp\u003eSpecify 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.\u003c\/p\u003e\n\n\u003cp\u003eOn 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.\u003c\/p\u003e\n\n\u003ch3\u003eSpecification\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCapacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4–6 people in the hot room\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eExternal size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4050 mm L × 2400 mm W × 2200 mm H\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLayout\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHot room plus covered open terrace — heater on the divider\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHeated volume\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eapprox. 7 m³ (total shell approx. 15 m³)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSide walls\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e42 mm thermowood\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRear wall\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e28 mm thermowood\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDoor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1650 × 590 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWindow\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e770 × 570 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBenches\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eThermo-aspen — stays cool to the touch at temperature\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRoof\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBitumen shingles — black, red, green or brown\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBands\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eStainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDelivery\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFlat-packed on pallets — ask us for the exact crate list\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\u003ch3\u003eWhat's in the box\u003c\/h3\u003e\n\u003cp\u003eEverything structural.
