| Installation | Almost Heaven lists a 240 V, 40/45 A hard-wired connection for the 8 or 9 kW electric heaters. For the 8 kW KIP, the dials version of the KIP manual calls for a 40 A double-pole breaker. It specifies 8/2 copper wire with 90°C insulation. Harvia's KIP manual lists a 33.3 A draw at 240 V. A licensed electrician must do the wiring, and the heater is wired permanently, with no plug or pigtail. The dials manual says not to use a ground fault interrupter (GFI), citing the heater's UL listing. The LED light plugs into a standard 110 V, 15 A outlet, or an electrician can hard-wire it. Build on a firm, level base such as concrete, pavers, decking or stone. On bare ground, set the cradles on pavers. Assembly takes a drill, rubber mallet, hammer, framing square, screwdrivers, utility knife, level and wrench. You'll need two or more people to lift heavy pieces. Almost Heaven doesn't state an assembly time. Almost Heaven's installation partner, Pure Install, charges from $1,400, with final pricing in a custom quote. That covers assembly, setup and a site walkthrough. Electrical connection is an optional add-on and must be done by a licensed electrician. Delivery is scheduled separately, and unloading the flatbed is your job. Almost Heaven says 2 to 4 people can offload it piece by piece in 1 to 2 hours. You can also rent a forklift. Expect a call 1 to 2 weeks before delivery. | The 9 kW Spirit heater runs on 240 V single-phase power and has to be wired by a licensed electrician. Almost Heaven's Spirit guide calls for a 50 A double-pole breaker and 8/2 copper wire rated 90°C. Don't put it on a ground fault interrupter (GFI). The guide cites the UL listing and says a GFI will damage the heater. The heater's power unit goes in a dry spot or a ventilated weatherproof enclosure, never inside the sauna. Almost Heaven's FAQ says cabins need a prepared foundation, and concrete is typically best. The manual asks for a firm, level base that holds 1,000+ lb, with pavers if it sits on the ground, plus a moisture barrier and anchoring. It also says to check local building codes. The tool list includes a cordless drill, rubber mallet, level, ladder and a table or skill saw. Heavy pieces take two or more people to lift. No assembly time is given. It ships in 8 to 12 weeks with curbside delivery. Larger models come by flatbed, which you unload yourself, piece by piece with 2 to 4 people or with a forklift. The LED light bar's manual says its power supply plugs into a 110 V outlet. Almost Heaven's installation service starts at $1,400, and electrical hookup costs extra. |

It says not to treat the interior unless the product is approved for saunas. | Nordic spruce inside and out, in 1 5/8 in planks, with linden interior fittings. The window is double-glazed and fixed. The outer wooden door locks, and Almost Heaven describes the doors as insulated. The roof ships with roofing felt only, and the manual says to finish it with shingles or metal roofing that you buy separately. Don't paint or varnish the outside.
