Comparing iTHERAU Portable Sauna Specs
Heater power
The iTHERAU Portable Steam Sauna with Red Light uses a 1300 W heater, while the iTHERAU 2-Panel Infrared Steam Sauna Box has a 1200 W unit. Both models heat their 3 L water tanks quickly, with the first model promising heat in 6 to 10 minutes. The higher wattage in the first model suggests it may reach your target temperature slightly faster than the second unit. This difference is small, but it could matter if you prefer the quickest possible warm-up time before you start your session. Both heaters include safety features like dry-burn prevention to protect the element.
Red light panels
The iTHERAU 2-Panel Infrared Steam Sauna Box includes two independent professional-grade red light therapy panels, providing full-body coverage with 660 nm and 850 nm wavelengths. In contrast, the iTHERAU Portable Steam Sauna with Red Light lists red light therapy as a feature but does not specify the number of panels or their placement. Having two dedicated panels in the second model ensures more consistent light exposure across your body during your session. This dual-panel setup is a distinct advantage for users who prioritize therapeutic red light coverage alongside the steam heat.
Timer range
You can adjust the session length differently on each unit. The iTHERAU Portable Steam Sauna with Red Light offers a digital timer that goes up to 99 minutes. The iTHERAU 2-Panel Infrared Steam Sauna Box allows you to set the timer for up to 90 minutes. Both units let you control the time via remote or manual buttons. The first model gives you an extra nine minutes of run time if you prefer longer sessions. This is a minor difference, but it provides slightly more flexibility for extended relaxation periods in the first sauna.
Interior material
The build materials differ between the two designs. The iTHERAU 2-Panel Infrared Steam Sauna Box is constructed from thickened 450D oxford fabric, which offers high tear resistance and effective heat retention. The iTHERAU Portable Steam Sauna with Red Light uses wipe-clean fabric with five-layer waterproof insulation. Both fabrics are designed to keep heat inside the chamber efficiently. The 450D oxford fabric in the second model is explicitly noted for its durability and resistance to tearing, which may appeal to you if you plan to move the unit frequently.
Person capacity
The iTHERAU 2-Panel Infrared Steam Sauna Box is rated for two people, allowing you to share the experience with a partner or friend. The iTHERAU Portable Steam Sauna with Red Light does not list a specific person capacity in its specifications, though its interior dimensions are identical. The pentagonal structure of the second model is engineered to fit adults comfortably, and the two-person rating suggests it accommodates shared use well. If you intend to use the sauna alone, both provide ample space, but the second model explicitly supports dual occupancy.
Which iTHERAU Sauna Fits You
Users wanting faster heat output
This model features a 1300 W heater, which is slightly more powerful than the 1200 W unit in the other option. The higher wattage helps fill the 3 L steam chamber with heat in just 6 to 10 minutes. If you prefer quicker warm-up times for your sessions, this extra power provides a tangible efficiency boost.
Those needing extra red light coverage
This sauna includes two independent professional-grade red light therapy panels instead of one. The dual-panel layout offers full-body light coverage, combining deep infrared penetration with steam therapy. If you want enhanced therapeutic power for circulation and muscle recovery, the double panels provide superior light distribution across your entire body.
Users preferring a visual safety window
This tent features a transparent visual window that allows natural light in. It also lets you stick your head out to breathe if you feel stuffy. Additionally, it includes storage pockets for your remote and a top hook for hanging towels. These design details add practical convenience and comfort during your sauna routine.
Shoppers valuing longer timer options
This portable sauna offers a digital timer that extends up to 99 minutes. The other model limits timing to 90 minutes. If you frequently enjoy longer relaxation sessions, the extended timer range on this unit gives you more flexibility to customize your experience without needing to restart the cycle mid-session.
