Short answer: the Model G2 is a 4-person outdoor cabin with 1.65” Nordic Spruce walls and a limited lifetime warranty for $4,990. The heater is not included. It is a good shell at a fair price, as long as you add the heater and wiring to your budget.
What size heater does it need?
The interior is 67.3” x 58” x 80.9”. Multiply and divide by 1,728 and you get about 183 cubic feet. Harvia rates its 4.5kW heater for 100 to 210 cubic feet and its 6kW for 170 to 300, so the G2 sits where the two overlap. My rule of thumb: when a room falls in the overlap and stands outdoors, take the larger heater, because an outdoor cabin loses more heat in winter. Confirm with the dealer.
A 6kW heater draws 25A at 240V and needs a dedicated circuit. The lighting runs on 120V, so the electrician brings two feeds.
Will it fit, and can you build it?
The exterior is 82.5” wide, 75.2” deep, and 86.4” tall at the front, about 43 sq ft. The maker describes assembly as a 2-person, 2-day job using interlocking beams. The door opening is 27.2” wide and 66.6” tall, so most adults duck slightly to enter.
Our data doesn’t state the weight. Ask before you plan the base.
Does wall thickness matter?
The walls are 1.65” thick. Thicker solid wood holds heat better and moves less with the seasons. Outdoor Sauna Wall Thickness explains how much difference it makes.
What the listing leaves out
The limited lifetime warranty goes to the original retail purchaser, but the dealer listing doesn’t spell out the terms. Ask for the document.
How it compares
You get the same $4,990 price as the indoor SaunaLife Model X2, with double the capacity. You give up nothing obvious on paper. The Dundalk MiniPOD costs $5,957 with a 4.5kW heater included. Bottom line: the G2 wins if your heater and wiring quote keeps the total under that. See the Home Sauna Buying Guide.
