Redwood Outdoors Cabin
4.0/ 5 our rating

The Redwood Outdoors Cabin is the most complete outdoor sauna kit, with a 6kW Harvia heater, rocks and roofing in the box for about $7,300, but the one-year structural warranty and 12-week-to-4-month lead times are real drawbacks.

  • Cabin shape beats a barrel for headroom and bench layout
  • Two-level seating for hotter and cooler spots

The Redwood Outdoors Cabin is a four-person outdoor sauna with two-level benches and gravity venting that ships with a 6kW Harvia KIP heater, sauna rocks and roofing. As of October 2026, it costs about $7,299. Unlike SaunaLife and Dundalk kits, that price includes the heater, which typically saves $1,200–$3,000. Owner experiences range from a smooth weekend build to long, poorly communicated delays.

Is the Redwood Outdoors Cabin worth it?

The Redwood Outdoors Cabin is worth it if you want a complete traditional sauna at a price close to your real total, and you can wait several months for delivery. The one-year structural warranty is the main reason to hesitate.

Great for

  • Buyers who don’t want to research heaters
  • Groups of up to four
  • Handy owners comfortable with a weekend build

Skip it if

  • You need it installed soon. Lead times run 3–4 months.
  • A long warranty matters. The SaunaLife CL5G has a lifetime warranty.

Heat and performance

The Redwood Outdoors Cabin’s included 6kW Harvia KIP is well matched to its size, with Wi-Fi and larger 8kW–9kW upgrades available. A Seattle owner of the 4-person Thermowood Cabin found the heater’s high-limit switch cut in near 175°F. They prefer about 165°F with plenty of löyly anyway, and Redwood offers a field recalibration to reach the advertised 195°F. The same owner says the walls don’t get hot outside, and that the ceiling is much hotter than the sensor reading.

Size, power and installation

The Redwood Outdoors Cabin needs a 240V circuit for the heater (installed by an electrician) and 120V for lighting, plus a level base. A 4-person cabin owner says, “if you are handy you can do this with a friend in a weekend. If you are not handy, reconsider.” The structure uses interlocking notches with few screws.

Delivery is the bigger variable. Owners report 10–12 weeks typically, while one buyer passed 15 weeks with missed callbacks before hearing it would be another four to eight weeks.

Build quality and durability

The Redwood Outdoors Cabin uses FSC-certified heat-treated wood with two-level benches. One owner says the Thermowood “has a very good firewood smell” and the finish is good. Several Redditors say Redwood sources kits from overseas manufacturers. Treat that as context on price rather than quality. Owners of other Redwood models report exterior trim chipping after a year of Pacific Northwest rain and heater mounting screws loosening, so inspect fixings periodically.

Features and extras

  • 6kW Harvia KIP heater and rocks included
  • Heater upgrades: Harvia KIP Wi-Fi, Spirit Wi-Fi, Virta, Homecraft (8–9kW)
  • Two-level seating for hotter and cooler spots
  • Gravity venting
  • Metal roof kit available (about $299)

What owners say

  • Build: a weekend job for handy owners, “very nice looking” Thermowood.
  • Heat: high-limit cutoff near 175°F out of the box, with recalibration available.
  • Support: “excellent response and customer support” for one buyer. Missed calls and vague delivery updates for another.
  • Trustpilot: 4.3/5 from about 359 reviews. Praise for sturdy kits and responsive service, and criticism of roofing instructions and backorders.
  • Skeptics: some Redditors flag poor past experiences and markup concerns.

Warranty and customer service

Redwood Outdoors offers a 1-year limited warranty on the sauna. The Harvia heater has its own warranty, typically 1 year on elements and 5 years on other components. That’s the shortest structural warranty among our outdoor picks, so inspect every panel on delivery and report issues immediately.

Price and total cost

Cost Typical amount
Cabin with 6kW Harvia About $7,299
Heater upgrade (optional) $300–$1,500
240V electrical + permit $500–$2,500
Base $500–$2,000
Metal roof kit (optional) About $299
Typical total $8,300–$12,000

Redwood Outdoors Cabin vs SaunaLife CL5G

The SaunaLife CL5G costs less upfront ($5,990), but adding a heater and freight usually brings its total above the Redwood Cabin. The CL5G has a lifetime warranty, thermally modified spruce and a glass front. Redwood wins on convenience and lower total cost. Read our SaunaLife CL5G review.

Final verdict

The Redwood Outdoors Cabin is the easiest way to get a complete traditional sauna in your yard, because the heater, rocks and roofing are all in the box. Order early, keep records of every communication, and inspect the kit thoroughly on arrival, given the one-year warranty.
