{"product_id":"ursa-outdoor-sauna","title":"URSA Outdoor Sauna: 3 to 4 Person Garden Sauna","description":"\u003cp\u003eThe URSA is the cabin in the middle of the range and the one most households end up with. Four people sit on two tiers along the back wall, the top bench 1.9 metres long and 625mm deep, and look out through a wall of darkened glass with a glass door in it. At 2,700 by 2,010mm it needs a real corner of the garden, and at 2,466mm tall it clears the 2.5 metre boundary cap by 34mm, which is close enough that the base decides the planning answer.\u003c\/p\u003e\n\u003cp\u003eA wall of glass ought to be a heat problem, and in a thin walled cabin it is. The URSA gets away with it because the other three walls are 55mm cross laminated timber, layers of wood bonded crosswise so the panel stays stable and holds heat the way a solid log wall does. The floor is 60mm of the same, designed to balance moisture and resist mould. Outside is thermally modified pine, inside is knot free thermo aspen and alder, and a roof overhang on the side gives you somewhere to hang towels out of the rain.\u003c\/p\u003e\n\u003cp\u003eTwo heaters, and the decision is not how much heat you want. It is whether you would rather call an electrician once or sweep a flue twice a year. The electric option is the 10.5kW Huum Hive Mini with its glass fronted UKU WiFi controller and 150kg of stones; the stone mass is the point, because 150kg holds heat and gives soft, lasting steam rather than the sharp dry heat of a small heater working hard. It connects to 400V three phase at 3 × 16A, or to a dedicated single phase circuit of around 50 amps, and we confirm the right connection for your supply before you order. The wood option is the Huum Hive Flow Mini, supplied with a through the ceiling flue kit, protective bedding, a spill guard and stones. It needs no electrical supply at all, and the ritual starts earlier, with a fire.\u003c\/p\u003e\n\u003cp\u003eThen one more choice: natural thermo pine, or the same cabin stained black. The black finish is a special order with a longer lead time, which we confirm before you commit. Everything else is already decided and already in the price.\u003c\/p\u003e","brand":"Tarnfell","offers":[{"title":"Electric, Huum Hive Mini 10.5kW \/ Natural thermo pine","offer_id":55193643647318,"sku":"TF-URSA-ELEC-NAT","price":21572.0,"currency_code":"GBP","in_stock":true},{"title":"Electric, Huum Hive Mini 10.5kW \/ Black","offer_id":55193643680086,"sku":"TF-URSA-ELEC-BLK","price":22172.0,"currency_code":"GBP","in_stock":true},{"title":"Wood burning, Huum Hive Flow Mini \/ Natural thermo pine","offer_id":55194812842326,"sku":"TF-URSA-WOOD-NAT","price":22111.0,"currency_code":"GBP","in_stock":true},{"title":"Wood burning, Huum Hive Flow Mini \/ Black","offer_id":55194812875094,"sku":"TF-URSA-WOOD-BLK","price":22711.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/9720\/0982\/files\/tarnfell-ursa-outdoor-sauna-01.webp?v=1788443574","url":"https:\/\/tarnfell.com\/products\/ursa-outdoor-sauna","provider":"Tarnfell","version":"1.0","type":"link"}
