Short answer: the Model X2 is a 1-2 person indoor spruce cabin on a 59” square footprint for $4,990. It is a traditional sauna that fits where most can’t. The heater is sold separately, and the cabin needs two electrical feeds.
What size heater does it need?
SaunaLife recommends a 4.5kW or 6kW electric heater on a dedicated 240V or 208V, 30A circuit. The interior is 54.1” x 51.5” x 78.1”, about 126 cubic feet. Harvia rates its 4.5kW heater for 100 to 210 cubic feet and its 6kW for 170 to 300. By that table, 4.5kW fits this room and 6kW is above the range. Ask the dealer why you’d choose the larger one before paying for it.
A 4.5kW heater draws about 18.8A at 240V and uses up to 4.5 kWh per hour, about $0.83 at 18.34 cents per kWh.
The lighting runs on a separate 120V line. Budget for an electrician to install both.
Will it fit indoors?
The exterior is 59.1” x 59.1” x 80.75”, about 24 sq ft. A height of 80.75” is 6 ft 8.75 in, so it clears an 8 ft ceiling but not a 6 ft 8 in basement soffit. It weighs 948 lbs, which is about 39 lbs per sq ft. That is fine on a concrete slab. On an upper floor, ask a builder.
The maker describes assembly as 4 to 6 hours for two people. The panels still have to get through your doors, so ask for the largest panel size.
Here’s what the spec sheet won’t tell you
Indoor traditional saunas put out moisture and heat. Plan the ventilation and the flooring under and around the cabin. The warranty term isn’t in our data for this model, so ask the dealer.
You get, you give up
You get Nordic Spruce walls, an Aspen bench, an 8mm glass door, and Wi-Fi LED lighting. You give up an included heater and a second seat for comfortable lying down.
How it compares
The Almost Heaven Sutton is a 2-person indoor cabin at $4,667 with a 6kW heater included. That is the tougher comparison. Small Space Sauna lists what fits where.
