Redwood Outdoors has become one of the most visible sauna brands in the home wellness market — their barrel saunas and cabin saunas appear in home gym tours, recovery room setups, and backyard wellness installations across the country. The brand has built a strong reputation, but reputation in a fast-growing category can sometimes outrun quality. Serious buyers deserve an honest assessment of what Redwood Outdoors actually delivers.
This review covers build quality, wood specifications, heater options, the full product range, what the ownership experience is actually like, and who this brand genuinely suits.

Brand Background: Who Is Redwood Outdoors?
Redwood Outdoors is a US-based company focused specifically on outdoor saunas — barrel saunas, cabin saunas, pod saunas, and outdoor shower enclosures. Unlike some competitors who import generic sauna kits under a private label, Redwood Outdoors designs their own products with specific attention to the materials and construction details that affect outdoor sauna performance and longevity in real climate conditions.
Their product line is positioned at the quality end of the consumer market — above generic kit-imported barrel saunas and below bespoke custom-built sauna contractors. Redwood Outdoors barrel saunas run $3,500–$7,500 depending on size and configuration, which is above the generic import category but well below commercial or custom sauna pricing.
One important note: "Redwood" is a brand identity choice, not a material specification. Not all Redwood Outdoors saunas are built from redwood lumber — their material specifications vary by product line and are worth examining specifically for each model you're considering.
Wood Quality: Cedar Grade and Construction
Wood quality is the most important long-term durability variable in any outdoor sauna — and the area where the widest variation exists across the market.
Wood species: Redwood Outdoors uses Western Red Cedar as the primary material for most of their product line. This is the correct choice for an outdoor sauna — Western Red Cedar is the industry standard for exterior sauna construction because it's naturally resistant to moisture, naturally antimicrobial, dimensionally stable through repeated heating and cooling cycles, and produces the characteristic aromatic experience traditional sauna users seek. Some models use Canadian Hemlock or Basswood for interior bench surfaces — verify the species specification for the specific model you're considering.
Wood grade: Clear-grade Western Red Cedar — free of knots and structural defects — is the premium specification. Redwood Outdoors uses clear-grade cedar on most models' exterior barrel staves and structural components. Knotted cedar is less expensive and more rustic aesthetically; knots can also become weak points that crack over years of thermal cycling.
Barrel stave thickness: Typically 1.5 inches thick. This provides adequate insulation for maintaining sauna temperatures efficiently in most climates. Thinner staves (1 inch or less) found on lower-cost competitors require more heater work to reach and maintain temperature and provide less thermal mass for the smooth, stable heat experienced sauna users value.
Wood treatment: Exterior cedar surfaces typically receive a UV-protective treatment at the factory, slowing the natural silver-gray weathering process that untreated cedar undergoes with outdoor exposure. Annual reapplication of cedar oil or exterior wood treatment is recommended to maintain the protection. See our seasonal equipment maintenance guide for the full sauna maintenance schedule.
Heater Options and Quality
Electric heater options: Redwood Outdoors partners with established heater brands — primarily Harvia and similar Finnish-heritage manufacturers — for the electric heaters in their sauna kits. Harvia is a well-regarded Finnish company with a strong track record in both commercial and residential sauna applications. Heater wattage is sized to the sauna volume: 3–4 kW for smaller barrel saunas, 6–9 kW for larger cabin and pod saunas.
Electric heater installation requires a 240V dedicated circuit. If your sauna location doesn't have this, factor the electrician cost ($400–$800 for a new outdoor 240V circuit) into your total budget. For the full temperature targeting framework for electric heaters, see our sauna temperature guide.
Wood-burning heater options: Available on select barrel sauna models. Wood-burning creates the most authentic traditional sauna experience — the smell of burning wood, the specific heat quality of wood fire, and independence from electrical service make wood-burning heaters appealing for off-grid installations and purist sauna enthusiasts. Practical requirements: a cord of wood per season of regular use, ash disposal, and ongoing fire management during sessions. Not the right choice for buyers who want push-button convenience.
Product Range: Barrel, Cabin, Pod, Indoor
Barrel saunas: The signature Redwood Outdoors product. The cylindrical barrel design is not purely aesthetic — curved walls reflect heat toward the center more efficiently than flat walls, and the absence of corners eliminates cold spots that form at corner-meeting walls of rectangular saunas. Available in 4-foot, 5-foot, and 6-foot diameter configurations in lengths from 6 to 8 feet, accommodating 2 to 6 users depending on configuration.
The barrel design does have a practical limitation: seating is on curved benches that follow the barrel wall, and the seating position is fixed. Users who specifically want to recline or stretch fully during sessions may prefer the cabin format.
Cabin saunas: Traditional rectangular design with a pitched or flat roof and vertical walls. More floor space per cubic foot than a barrel, more flexibility in seating arrangements, and the ability to add benches in multiple configurations. Larger footprint than equivalent-capacity barrels. Right for buyers who plan to use the sauna primarily with multiple people simultaneously or who want the flexibility of a traditional sauna room layout.
Pod saunas: A newer product category — egg or pod-shaped enclosed saunas that combine the efficient heat distribution of curved walls with a more modern aesthetic than the traditional barrel. More compact than equivalent-capacity cabin saunas. Higher price point than barrels for equivalent capacity. Best for buyers who specifically value the contemporary aesthetic.
Indoor infrared units: Redwood Outdoors' indoor lineup uses the brand name but is a meaningfully different product from their outdoor traditional sauna line — prefabricated panel saunas with infrared panels rather than traditional heaters. For comparison with other infrared options, see our infrared vs. traditional sauna guide and our sauna buying guide for small spaces.
Assembly: What to Expect
Redwood Outdoors saunas ship as pre-cut, pre-drilled kits with labeled components. Assembly is designed for two people with basic construction skills over a weekend.
Typical assembly timelines:
- Barrel sauna (4–6 person): 6–10 hours for two people
- Cabin sauna: 8–14 hours for two people
- Pod sauna: 4–8 hours for two people
The most common assembly challenge reported by Redwood Outdoors customers: fitting the barrel staves precisely during initial barrel assembly. The staves need to be tight enough to seal the barrel against water infiltration while allowing for the seasonal expansion and contraction of the cedar.
Assembly of the electrical components — connecting the heater, running wiring to an exterior disconnect box — should be done by a licensed electrician in most jurisdictions, as electrical work for outdoor applications is typically permit-required.
Redwood Outdoors vs. The Competition
In the outdoor sauna category, Redwood Outdoors competes most directly with Almost Heaven (another US barrel sauna brand) and direct-import generic barrel sauna kits available through Amazon and manufacturer import channels.
vs. Generic import kits: Redwood Outdoors delivers meaningfully better cedar quality, better hardware (stainless steel rather than zinc or galvanized fasteners in most configurations — significant for outdoor longevity), and better US-based customer support. The price premium (typically 30–60% over generic kits) reflects these quality differences.
vs. Almost Heaven: These two brands are the closest competitors in the US market and are frequently compared directly by buyers. Both use quality cedar and offer similar product configurations. Redwood Outdoors tends to have a slight edge in cedar grade consistency; Almost Heaven tends to offer more configuration options within each product category. Either is a quality purchase — if a specific configuration is available from one brand and not the other, that may be the deciding factor.
Who Redwood Outdoors Is Best For
- Home gym owners with outdoor space who want a traditional sauna experience with steam (löyly) capability that indoor infrared saunas don't provide
- Buyers building a contrast therapy setup with an outdoor sauna alongside a cold plunge tub — the outdoor placement makes contrast therapy movement between sauna and cold plunge natural. See our contrast therapy guide and cold plunge buying guide.
- Anyone who specifically wants the aesthetic of a cedar barrel or cabin sauna as a backyard feature
- Buyers willing to invest in a quality outdoor installation that will last 15–20+ years with appropriate maintenance
- Buyers who value a US-based company with accessible customer support over direct import products
Who Should Look Elsewhere
- Buyers whose primary use case is daily post-workout recovery — an indoor infrared sauna is more convenient, easier to maintain, and adequate for the recovery purpose without outdoor installation complexity. See our sauna buying guide for small spaces for compact indoor options.
- Apartment or condo buyers — Redwood Outdoors products are outdoor installations requiring private outdoor space
- Buyers on strict budgets — quality indoor infrared alternatives starting at $1,800–$2,500 deliver excellent recovery benefits at lower total cost
- Buyers who want plug-in simplicity without assembly, electrical work, or ongoing wood maintenance
