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.

Clean by Design

OEKO-TEX® Certified. Anti-Microbial. Built to Stay Fresh.

Steam environments are naturally damp — so we built in materials that fight back. The SmartSteam XL interior is lined with anti-microbial fabric that resists mold and bacteria accumulation between sessions. The tent fabric itself is OEKO-TEX® certified, meaning it's been independently tested against strict global standards for harmful substances. After each session, simply leave the door flap open to air out and wipe down condensation. That's the full maintenance routine.

  • OEKO-TEX® certified tent fabric — tested for harmful substances
  • Anti-microbial interior lining resists mold and bacteria
  • Machine washable SweatLock floor mat
  • Simple post-session care: air out + wipe down

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. The interior is also lined with anti-microbial materials to resist mold and bacteria. This certification applies to both the tent fabric and is verified by a third-party accredited testing body — not self-reported by the manufacturer.
Yes. The XL interior measures 56 inches wide × 49 inches deep × 53 inches tall, which is sized to seat two adults comfortably with room to sit side-by-side. The SweatLock Floor Mat provides cushioning underfoot. It's not a standing sauna — users sit inside — but the dimensions give two people genuine comfort for a full 20–45 minute session without crowding.
Maintenance is minimal. 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. The anti-microbial interior lining does most of the hygiene work passively. Avoid harsh chemical cleaners on the interior fabric. Periodic airing and mat washing are all that's needed for regular use.
The SmartSteam XL operates on standard 110V household current at 1,600 watts (50/60 Hz). 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. Do not use in outdoor environments or near water sources beyond the sealed water reservoir.
Yes — the SaunaBox® SmartSteam XL may qualify as an HSA/FSA-eligible purchase for customers with qualifying medical conditions, processed through Truemed at checkout. Eligible customers typically save 25–35% by using pre-tax health dollars. Eligibility is determined at the time of purchase based on your health account and qualifying condition — check Truemed's qualification process at checkout for details.
The SaunaBox® SmartSteam XL is backed by a 1-Year Limited Warranty covering manufacturing defects in materials and workmanship. Contact SaunaBox® customer support directly for warranty claims, with your order confirmation as proof of purchase. The warranty covers the SmartSteam™ Pro unit, the tent structure, and included accessories under normal use conditions.
