SMARTMAK Outdoor Barrel Steam Sauna – 1–2 Person Spruce Wood Sauna Room

Transform your backyard into a private wellness retreat with the SMARTMAK Outdoor Barrel Sauna. Crafted from durable Canadian Spruce and powered by a genuine 4.5KW Harvia electric heater, this self-contained barrel sauna delivers an authentic wet steam experience for one or two people — right at home, any day of the year.

Key Features

• Spacious 2-Person Interior: Generously sized at 47"W × 71"D × 71"H, there's plenty of room to relax solo or share the experience with a family member or friend — no waiting in line at the spa.
• 4.5KW Harvia Electric Heater: The included 220V / 4.5KW Harvia internal-control stove heater warms the sauna quickly and efficiently. Timer adjustable from 0–60 minutes; temperature settable from 32–194°F (0–90°C) — total control at your fingertips.
• Double Reinforcement Construction: Heavy-duty 304 stainless steel bands are compression-locked at every corner for lasting structural integrity. A weather-resistant EPDM rubber base shields the wood from ground moisture, so you can enjoy your sauna year-round, rain or shine.
• Multi-Layer Waterproofing System: Precision-fit wooden panels feature seamless joinery and airtight silicone seals to block moisture. A tear-resistant tarp lining and architectural asphalt shingle roof with high-density roofing underlayment provide double protection and a longer lifespan than single-layer roofs.
• Premium Canadian Spruce Wood: Panels are selected for outstanding thermal stability, natural beauty, and long-term durability — the hallmark of a classic Finnish-style sauna.
• Everything Included: Your sauna set comes complete with an 8mm tempered glass door, wooden door handle, 4.5KW Harvia heater, volcanic sauna stones, hourglass, hygrometer, bucket and scoop, rubber hammer, wall lamp, full roof system, and 304 stainless steel banding bands.
• Computer Control Panel: Intuitive digital controls make it simple to set your ideal temperature and session duration without any guesswork.
• Self-Contained Design: Engineered for straightforward self-installation — no special construction or permanent structure required.
