Cedar Saunas
Cedar Saunas
Cedar is the gold standard material for sauna construction — used across traditional, infrared, barrel, and hybrid saunas alike. Western red cedar and Canadian cedar contain natural oils that resist moisture, regulate humidity, and release a distinctive warm aroma when heated. Whether you're choosing an indoor infrared model, an outdoor barrel sauna, or a full traditional steam room, cedar wood elevates the experience and outlasts almost any alternative.
- Natural Moisture Resistance: Cedar's oils and tannins resist warping, cracking, and mold without chemical treatment — critical in the high-heat, high-humidity sauna environment
- Stays Cool to the Touch: Cedar's low thermal conductivity means interior surfaces, benches, and walls remain comfortable even at 170–190°F
- Natural Aromatic Properties: Heated cedar releases compounds that create the distinctive sauna scent — part therapeutic, part atmosphere
- Used Across All Sauna Types: Cedar is the standard wood for traditional Finnish saunas, infrared panels, barrel staves, and hybrid sauna cabinets
- Long-Term Durability: Quality cedar saunas last 15–20+ years with basic maintenance — one of the best long-term investments in home wellness
- Pre-Cut Assembly: Most cedar sauna kits use tongue-and-groove panels that assemble without special carpentry skills
Frequently Asked Questions
What makes cedar the preferred wood for sauna construction?
Cedar contains natural oils — primarily thujaplicins — that make it exceptionally resistant to moisture, mold, and insects without any chemical treatment. More importantly for sauna use, cedar has low thermal conductivity, meaning the wood surfaces stay comfortable to touch even at high operating temperatures. It also holds its shape through repeated heat-and-cool cycles better than most alternatives, and releases a natural aromatic scent when warmed that enhances the sauna atmosphere. These properties together make it the standard choice for sauna interiors, benches, and barrel stave construction across the industry.
What types of saunas use cedar construction?
Cedar is used across virtually every sauna type. Barrel saunas are almost universally built from cedar staves — the curved wood construction is both structural and aesthetic. Traditional Finnish saunas use cedar for interior benches, walls, and ceilings. Infrared saunas like the Finnmark and Maxxus models use cedar for the cabinet and interior surfaces that surround the heating panels. Hybrid saunas like the Medical Breakthrough Nature series also feature cedar interiors. The heating technology varies; the material standard doesn't — cedar is the consistent choice across all of them.
What's the difference between Western Red Cedar, Canadian Cedar, and other wood types used in saunas?
Western Red Cedar (Thuja plicata) is widely considered the premium sauna wood — it has the highest natural oil content, the most pronounced aroma, and the best dimensional stability under heat cycling. Canadian Cedar is often used interchangeably with Western Red Cedar since most is sourced from British Columbia. Hemlock is a common mid-range alternative: lighter in color, odorless, and structurally sound, but without cedar's aromatic or antimicrobial properties. Nordic spruce and abachi are used in European and African sauna construction respectively. For outdoor saunas or barrel construction where moisture resistance is critical, cedar is strongly preferred over hemlock or spruce.
How difficult is it to assemble a cedar sauna?
Most cedar sauna kits are designed for DIY assembly using pre-cut, pre-drilled tongue-and-groove panels. Assembly typically takes 4–8 hours with 2 people and basic tools — a drill, level, rubber mallet, and screwdriver. The wood assembly itself doesn't require carpentry expertise. The electrical connection for the heater does require a licensed electrician in most jurisdictions, particularly for 240V installations. Barrel saunas follow a similar pattern: stave assembly is mechanical and manageable, but the heater wiring needs professional handling.
What electrical requirements do cedar saunas have?
It depends on the heating type, not the wood. Cedar infrared saunas like the Maxxus 2-person model typically run on a standard 120V/15–20A dedicated circuit. Larger infrared models (3–4 person) often require 240V/20–30A. Traditional cedar saunas with electric heaters need 240V/40–60A depending on heater wattage (typically 4.5–9kW). Barrel saunas with wood-burning heaters require no electrical connection at all. Check the specific model's spec sheet — the cedar construction has no bearing on the electrical requirements.
Can cedar saunas be used outdoors year-round?
Yes — cedar's natural weather resistance makes it one of the few sauna woods genuinely suited to year-round outdoor exposure. Barrel saunas in particular are almost always cedar and designed for permanent outdoor placement. For box-style outdoor cedar saunas, a weather-resistant roof and proper drainage are important, but the wood itself handles temperature extremes, rain, and snow well. In very harsh climates (sustained below-zero winters), storing the sauna under a covered area or applying an exterior stain every few years extends the lifespan. Untreated cedar will weather to a silver-gray patina over time — cosmetically different, but structurally sound.
How do I maintain a cedar sauna interior?
Cedar sauna interiors need very little maintenance. Wipe down benches and walls with a damp cloth after sessions and allow to air dry with the door open. Avoid soap, bleach, or chemical cleaners on interior cedar — they're unnecessary and can damage the wood's natural properties. If benches develop a rough texture over time, light sanding with 220-grit sandpaper restores them. Never apply varnish, paint, or sealant to interior cedar — the wood needs to breathe, and coatings can off-gas unpleasantly at sauna temperatures. Exterior cedar on outdoor saunas benefits from an annual inspection and a UV-protective stain every 2–3 years.
What warranty coverage do cedar saunas carry?
Warranty terms vary by manufacturer. Finnmark and Maxxus cedar infrared models typically include 5–7 years on the cedar structure, 3–5 years on electrical components, and 1–2 years on accessories. Medical Breakthrough carries one of the stronger warranties in the market. Most barrel sauna manufacturers (SaunaLife, Golden Designs) offer 1–5 years on structural components. Always verify the warranty covers both materials and workmanship — some lower-cost models only cover manufacturing defects, not wood movement or checking (minor surface cracks from heat cycling) which is normal cedar behavior.
How much space do I need for a cedar sauna?
Space requirements vary by sauna type. A 2-person indoor infrared cedar sauna typically needs a 4'x4' footprint plus 6–12 inches clearance on all sides for ventilation. 3–4 person models need roughly 5'x6' to 6'x6'. Barrel saunas are wider than they are deep — a 4-person barrel runs approximately 6–7 feet in diameter and 6–7 feet long, so plan for an 8'x10' outdoor footprint including clearance. For all models, ceiling height should be at least 7 feet indoors; barrel saunas are self-contained and don't have ceiling height requirements for the structure itself.
What are the operating costs for a cedar sauna?
Operating costs depend on heating type, sauna size, and local electricity rates. A 2-person cedar infrared sauna typically draws 1.5–2kW per session, costing roughly $0.30–$0.60 per hour. A traditional 4-person cedar sauna with a 6kW heater runs $0.90–$1.80 per hour depending on electricity rates. Wood-burning barrel saunas have no electricity cost — just firewood. Cedar's natural insulation properties help maintain temperature efficiently, but the wood type itself has minimal impact on operating costs compared to heater size and sauna volume.
How do cedar barrel saunas compare to cedar box-style saunas?
Both use cedar construction, but the form factor changes the experience significantly. Barrel saunas heat faster because the curved interior has less dead air volume — a 4-person barrel can reach operating temperature 20–30% faster than a rectangular sauna of similar capacity. They're almost always designed for outdoor use, often use wood-burning or electric heaters (not infrared), and have a more rustic aesthetic. Box-style cedar saunas offer more layout flexibility, are available as both indoor and outdoor models, and are more commonly available with infrared heating. If you want the traditional outdoor wood-burning experience, cedar barrel. If you want infrared or an indoor option, cedar box-style is the practical choice.
Who should buy a cedar sauna?
Cedar saunas are a good fit for anyone who wants a long-term home wellness investment and values natural materials. They're particularly well-suited to outdoor installations where cedar's weather resistance is a practical advantage. Regular sauna users — 3+ sessions per week — will appreciate cedar's durability over cheaper alternatives. Anyone sensitive to synthetic materials or off-gassing will find cedar's all-natural construction appealing. If you're comparing cedar vs. hemlock at a similar price point, cedar is almost always worth the small premium for the improved moisture resistance and aromatherapy benefit.

Key Benefits
Heated cedar releases natural oils that produce the distinctive sauna scent associated with premium wellness facilities. This isn't added fragrance — it's the wood itself, and it improves with repeated heat cycles as the oils slowly activate from deeper in the grain.
Cedar's natural tannins make it significantly more resistant to rot, mold, and moisture damage than pine, hemlock, or spruce — without chemical treatment. This matters particularly for outdoor saunas and traditional steam saunas where surfaces see repeated moisture exposure.
Cedar's low thermal conductivity is what makes it the standard sauna bench material — surfaces don't get dangerously hot at 160–190°F the way metal or denser hardwoods would. You can sit, lean, and touch cedar surfaces comfortably throughout your session.
Cedar is used in infrared sauna cabinets, traditional sauna walls and benches, barrel stave construction, and hybrid sauna interiors. Choosing cedar doesn't constrain your heating options — it's the standard material regardless of whether you prefer infrared, traditional steam, wood-burning, or hybrid.
Quality cedar saunas routinely last 15–20+ years with basic maintenance. Cedar barrel saunas used outdoors year-round in harsh climates commonly outlast cheaper alternatives by a decade or more. The initial material cost is offset many times over by longevity.
New cedar has a warm reddish-brown tone that deepens with heat exposure over the first months of use. Left untreated outdoors, it weathers to a distinguished silver-gray patina. Either way, cedar ages attractively — unlike cheaper woods that simply look weathered and worn.

Space & Placement Guide
| Consideration | Recommendation |
|---|---|
| Foundation Surface | Level concrete pad, composite decking, or compacted gravel base for outdoor cedar saunas. Indoor models need a flat, water-resistant floor — sealed concrete, tile, or vinyl plank all work. Even 1–2° of slope can cause door misalignment over time. |
| Clearance Space | Minimum 12–24 inches on all sides for maintenance access and air circulation. Cedar expands slightly in humidity — allow clearance from tight walls to prevent panel warping. Allow 36 inches in front of the door for safe entry and exit. |
| Electrical | Cedar infrared saunas (2-person): typically 120V/15–20A dedicated circuit. Larger infrared or traditional models: 240V/30–60A. Wood-burning barrel saunas: no electrical needed. Always use a GFCI-protected outlet and consult a licensed electrician for any 240V connections. |
| Ventilation (Indoor) | Indoor cedar saunas need intake and exhaust ventilation — typically a low intake vent near the floor and a high exhaust vent near the ceiling. Prevents moisture buildup in the surrounding room and extends cedar life. Basement installations often require a dedicated exhaust fan. |
| Sun Exposure (Outdoor) | Partial shade is ideal for outdoor cedar saunas — direct afternoon sun can fade exterior finish and overheat the structure before sessions. Morning sun helps dry overnight condensation. Avoid deep shade that keeps cedar damp between uses. |
| Drainage | Slope the ground or foundation 1/4" per foot away from the sauna base. Standing water around cedar sill plates accelerates rot even on weather-resistant cedar. A French drain or gravel apron around the perimeter of outdoor saunas is a worthwhile addition. |
| Post-Session Care | Leave the sauna door slightly open after sessions to allow moisture to escape and cedar to dry. This is the single most effective thing you can do to extend cedar life — trapped humidity is the main cause of premature degradation in any wood sauna. |
