Before you order
This page gathers what Cedarbrook publishes about the 5x7 kit, checked Oct 10, 2026, and adds up what it costs to install.
Who should buy the 5x7 kit?
The 5x7 suits someone who wants a square outdoor room with thick walls and the heater in the price. Cedarbrook builds its 4-inch panels of clear western red cedar in Woodinville and Cashmere, Washington, with no glue or plywood, and it rates them at R-20. An 8 kW Finlandia heater and a slant metal roof come with the kit.
Setri's Nordheim Loki seats five for about $2,200 less and heats with a wood stove. Almost Heaven's Blackwater is a bigger cube with Wi-Fi control.
What does it take to install?
The room measures 5 feet 8 inches by 7 feet 8 inches outside and sits on pavers, a slab or a platform you supply. The heater needs a 240V, 40-amp breaker on 8-gauge wire, run by an electrician. Each panel weighs 100 to 150 pounds, so line up help, since Cedarbrook installs only in Washington.

What to know before you buy
Western red cedar, electric, 240V hardwired. These decide whether it suits your space and your electrical panel.
- Western Red CedarWestern Red Cedar is the high-end sauna wood, and it resists rot and insects naturally. It's aromatic and conducts heat poorly, so benches stay cool enough to sit on at 194°F (90°C).
- ElectricAn electric heater holds a steady temperature on its thermostat and needs no chimney. Many models add app or timer control.
- 240V HardwiredA hardwired model needs a dedicated 240V circuit installed by an electrician. Build roughly $600–$2,500 into your total budget for it.
