SaunaBox Portable Steam Sauna Review: What Michael Kummer Actually Said
Updated December 22, 2025, Kummer praised SaunaBox as an affordable, one-person steam sauna that matches the cardio load of hotter units thanks to near-100% humidity.
Kummer didn’t publish a numeric score; this composite reflects his main points: strong value and sweat effect, quick setup, minor knocks for max heat and solo capacity.
Product Overview
SaunaBox is a portable steam tent powered by an external unit with seven heat levels. On its highest setting it reaches about 115–120°F, but the near-100% humidity created a cardiovascular load similar to Kummer’s infrared and barrel saunas that run far hotter.
He calls it “an affordable way to make sauna bathing part of your routine,” noting it ships with labeled fiberglass poles, a ThermoShield cover, steam unit, folding chair, washable floor mat, towel, and carrying case.
What He Liked Most
- Full sweat and heart-rate response despite the lower temperature cap.
- Sub‑15‑minute assembly; lightweight enough to move after setup.
- Materials tested BPA‑ and microplastic‑free with ROHS/REACH compliance.
- Price of $449 (often less with his code) undercuts most personal saunas.
- Washable floor mat and quick wipe‑down routine keep upkeep simple.
Tradeoffs He Flagged
Capacity + Comfort
- Designed for one person; legroom can feel tight if you’re ~6' tall.
- Chair repositioning or swapping to a taller stool helps head/leg room.
Heat & Materials
- Max temp ~120°F; relies on humidity for intensity vs. high dry heat.
- Cover off‑gasses a bit at first—air it out and run a few empty sessions.
- Best used in a ventilated or covered area to manage moisture.

Bottom Line
Kummer’s verdict: SaunaBox delivers the full sweat and heart-rate benefits of sauna therapy in a portable, budget-friendly package. If you’re okay with solo sessions and a 120°F cap that’s offset by heavy humidity, it’s a strong small-space option.
If you want a personal steam sauna you can set up in minutes and stow or move easily, SaunaBox hits the sweet spot on price, heat stress, and simplicity.
