Portable Steam Sauna
Your Personal Steam Sanctuary — Ready in Under 5 Minutes
Most people never get the regular sauna sessions their body needs — because a traditional sauna means a gym membership, a spa appointment, or a five-figure home installation. The SaunaBox® SmartSteam XL changes that. This app-enabled, 2-person portable steam sauna sets up in minutes anywhere in your home, delivering genuine therapeutic heat whenever you need it.
Steam heat works differently than dry heat. The SmartSteam XL reaches 130°F with 100% humidity, creating a high-humidity environment that penetrates deeper into muscles and joints. The moist heat opens pores effectively, promotes deep detoxification through sweat, and produces a full-body therapeutic experience that mimics the effects of a traditional steam room — at a fraction of the cost and with none of the commute.
Built for real life, the SmartSteam XL features a pop-up tent design with a durable fiberglass frame that collapses into a compact carrying case. Whether you use it after training, before bed, or as part of a dedicated wellness routine, the SaunaBox® mobile app puts precise control over temperature (1–15 levels) and session timing (up to 60 minutes) directly in your hands — on iOS or Android. OEKO-TEX® certified fabric ensures every session is as clean as it is restorative.

Common Questions
Frequently Asked Questions
Everything you need to make a confident decision — answered directly.
The SaunaBox® SmartSteam XL is a portable 2-person steam sauna that uses a 1,600-watt SmartSteam™ Pro Heating Unit to generate steam from a 3.6L water reservoir. The steam fills a fully insulated pop-up tent to temperatures up to 130°F with 100% humidity. You control heat level and session length through the SaunaBox® Bluetooth app on iOS or Android, or via the SmartSteam™ control unit directly.The SmartSteam XL reaches a maximum of 130°F (54°C) with 100% humidity. Steam heat at lower temperatures can feel significantly more intense than dry heat at higher temperatures — a 130°F steam environment produces a full-body therapeutic experience comparable to much hotter dry saunas. Most users find 15–20 minutes at mid-to-high heat settings effective for recovery and relaxation.Setup takes under 5 minutes for most users. The fiberglass pop-up frame deploys automatically — no assembly required. You clip on the SmartSteam™ unit, fill the 3.6L water reservoir, pair the app, and you’re ready. Breakdown and storage take roughly 2 minutes. The included carrying case keeps everything compact between sessions.Yes — the SmartSteam XL is a steam sauna, not an infrared sauna. It heats the air and your body through hot, moist steam at 130°F with 100% humidity. Infrared saunas use radiant heat to warm the body directly at lower air temperatures. Steam therapy is particularly effective for respiratory benefits, skin hydration, and deep sweat detoxification. Both modalities support recovery, but they work differently and produce different experiences.No. The SmartSteam XL tent fabric is OEKO-TEX® certified, meaning it has been independently tested and verified to be free from harmful substances under strict global standards.

After each session, leave the door flap open to air out and wipe down any water vapor on the interior with a dry cloth. The SweatLock Floor Mat is machine washable and quick-dry.

It plugs into a standard outlet — no special wiring, dedicated circuit, or electrician required. Ensure you’re using a grounded outlet and avoid extension cords where possible.
