Portable Steam Sauna

Your Personal Wellness Oasis — Anytime, Anywhere

The traditional sauna experience has always come with strings attached — a gym membership, a spa visit, or a permanent home installation that costs as much as a used car. The SaunaBox® SmartSteam Pro cuts all of that out. It's the original at-home portable steam sauna, refined over multiple generations and now trusted by professionals and everyday athletes alike, setting up anywhere in your home in about 15 minutes.

Steam heat isn't just hot air. The SmartSteam Pro reaches 130–140°F with near-100% humidity — and because water carries heat energy far more efficiently than dry air, that translates to a physiological experience comparable to a dry sauna running 30°F hotter. You get deep sweat, elevated heart rate, and real recovery benefits at temperatures your body can handle longer. Seven heat levels and a 0–60 minute timer give you precise control over every session.

What sets the SmartSteam Pro apart from cheaper competitors is its materials story. Every component — the ThermoShield tent, silicone tubing, and steam chamber — has been independently tested for microplastics, heavy metals, phthalates, and volatile organic compounds. It's the only portable steam sauna that is Certified Microplastics Free by Simple Lab®, California Prop 65 compliant, and RoHS certified. When you're sitting inside a steam environment, what your sauna is made of matters — and we have the test results to prove it.

SmartSteam Technology

The Science Behind Every Session

The SmartSteam Pro isn't a sauna tent with a bucket of water — it's an engineered steam system designed around real physiological outcomes.

♨️
V2 SmartSteam™ Pro Heating Unit
The second-generation SmartSteam™ Pro generates consistent, controllable steam from a stainless steel chamber and 3.6L reservoir. Seven heat levels from gentle warmth to full therapeutic intensity — with Bluetooth app control or the included handheld remote.
3.6L RESERVOIR · 7 HEAT LEVELS · 1600W
🌡️
130–140°F Steam Heat Science
Water has a higher heat capacity than air. In a steam environment, your body absorbs heat energy much faster than in a dry sauna at the same temperature. The SmartSteam Pro at 130–140°F with 100% humidity creates cardiovascular and sweat responses equivalent to dry saunas running well above 160°F.
130–140°F · NEAR 100% HUMIDITY
🏕️
V2 ThermoShield Frame Cover
The ThermoShield tent is built from a heat-insulating polyester-cotton blend with an anti-microbial interior lining. A durable fiberglass frame supports the structure. The sealed design traps steam efficiently — no heat bleeds out, no condensation pools on your floor. Indoors or outdoors.
ANTI-MICROBIAL INTERIOR · INDOOR + OUTDOOR
📱
Bluetooth App Control
The SaunaBox® app pairs via Bluetooth for full hands-free session control. Set heat level, run timers up to 60 minutes, and adjust your session from inside the tent without reaching for the control unit. Available on iOS and Android.

The microfiber hand towel and carrying case round out a package designed for people who actually want to use this regularly.

  • Portable chair included — designed to fit inside the tent footprint

Setup Guide

Three Steps. Fifteen Minutes. First Session Today.

1
Assemble the Frame & Tent
Connect the fiberglass frame sections and slip the ThermoShield cover over the frame. The whole structure takes about 10 minutes to assemble the first time — subsequent setups are faster once you know the configuration.
2
Fill the SmartSteam™ Reservoir
Pour distilled water into the 3.6L SmartSteam™ Pro chamber and attach it to the tent's heating port. Distilled water is recommended to prevent mineral buildup in the steam unit over time.
3
Heat Up — Ready in 15 Minutes
Set your heat level via the SmartSteam unit, handheld controller, or SaunaBox® app. Within 15 minutes, steam flows into the tent and you're at temperature. Place the portable chair and SweatLock mat, step in, and zip up.
4
Set Your Timer & Session
Use the app or controller to set your timer from 1–60 minutes. Most recovery sessions run 20–40 minutes. The system maintains temperature automatically throughout.
5
Post-Session: Air Out & Wipe Down
After your session, leave the tent flap open to air out and wipe down interior condensation. Wash the SweatLock mat as needed. The anti-microbial lining handles hygiene between sessions.

Common Questions

Frequently Asked Questions

Straight answers to the questions that matter before you buy.

The SaunaBox® SmartSteam Pro is a 1-person portable steam sauna. A 1,600-watt V2 SmartSteam™ Pro Heating Unit generates steam from a 3.6L stainless steel reservoir and pumps it into a fully insulated ThermoShield tent. The system reaches 130–140°F with near-100% humidity within 15 minutes. You control heat level (1–7) and session timer (0–60 minutes) via the unit, handheld remote, or SaunaBox® Bluetooth app on iOS or Android.
The SmartSteam Pro reaches 130–140°F with near-100% humidity. Because water has a higher heat capacity than air, the steam environment transfers heat energy to your body far more efficiently than dry heat at the same temperature. A 130–140°F steam sauna produces cardiovascular and sweat responses comparable to a dry sauna running above 160°F. Most users find 20–40 minute sessions at mid-to-high settings fully effective for recovery and relaxation.
Yes — and the certifications are third-party verified. The SmartSteam Pro is Certified Microplastics Free by Simple Lab®, California Prop 65 Compliant, and RoHS Certified. The ThermoShield cover was tested for lead, phthalates, heavy metals, flame retardants, and azo dyes — all showed zero detection. Silicone tubing is FDA 21 CFR 177.2600 and REACH compliant, tested for 235 substances of very high concern with none detected above threshold. Full certification details are available on the SaunaBox certifications page.
First-time assembly takes approximately 10 minutes to connect the fiberglass frame and fit the ThermoShield cover. Once the structure is assembled, fill the 3.6L steam reservoir and power on — the unit reaches operating temperature within 15 minutes. Subsequent setups are faster once you're familiar with the frame configuration. Breakdown and storage in the carrying case takes 5–10 minutes.
Yes — the SmartSteam Pro is designed for both indoor and outdoor use. For outdoor sessions, SaunaBox recommends setting up under an appropriate cover such as a canopy, balcony overhang, or tarp to protect the unit and tent from direct weather exposure. The ThermoShield cover performs well in outdoor environments and the fiberglass frame is durable enough for regular outdoor use with basic protection.
Post-session maintenance is minimal. Leave the tent flap open to air out after each use and wipe down any condensation on the interior walls with a dry cloth. The SweatLock Floor Mat is machine washable and quick-dry — wash it as needed. The anti-microbial interior lining passively resists mold and bacteria between sessions. SaunaBox recommends using distilled water in the steam reservoir to prevent mineral buildup in the heating unit over time.
SaunaBox recommends using distilled water in the 3.6L SmartSteam™ Pro reservoir. Distilled water prevents mineral and calcium scale buildup inside the stainless steel steam chamber, extending the unit's lifespan and maintaining consistent steam output. Filtered water is acceptable as an alternative; tap water with high mineral content is not recommended for regular use as it will accelerate scale buildup.
The SmartSteam Pro runs on standard 110V household current at 1,600 watts (50/60 Hz). It plugs into any standard grounded outlet — no dedicated circuit or special wiring required. Use a grounded outlet and avoid extension cords where possible. The unit should not be operated in areas with standing water or direct rain exposure.
Yes — the SaunaBox® SmartSteam Pro may qualify for HSA/FSA purchase through Truemed for customers with qualifying medical conditions. Eligible customers typically save 25–35% by using pre-tax health account dollars. Eligibility is determined through Truemed's qualification process at checkout and depends on your health account type and qualifying condition.
The SaunaBox® SmartSteam Pro includes a 1-Year Limited Warranty covering manufacturing defects in materials and workmanship under normal use conditions. Contact SaunaBox® customer support with your order confirmation to initiate a warranty claim. Coverage includes the V2 SmartSteam™ Pro unit, ThermoShield cover, fiberglass frame, and included accessories.
