Size, Capacity, and Build Comparison
Interior dimensions
The iTHERAU XL Infrared Sauna Box measures 45 inches long, 35 inches wide, and 73 inches high. This pentagonal design provides 20% more interior space than standard models, allowing you to sit or stand comfortably. The iTHERAU 2-Panel Infrared Steam Sauna Box is smaller, with dimensions of 32 inches wide, 32 inches deep, and 71 inches high. While both units claim to offer extra room to avoid cramped feelings, the XL model offers significantly more floor space and height. If you are taller or prefer more room to move, the XL dimensions are superior. The 2-Panel model is more compact, which may suit smaller rooms but feels tighter inside.
Person capacity
Capacity is a key differentiator between these two portable saunas. The iTHERAU 2-Panel Infrared Steam Sauna Box is explicitly rated for two people, allowing you to share the experience with a partner or family member. The iTHERAU XL Infrared Sauna Box does not list a specific person capacity in its published specifications. However, its larger interior footprint suggests it can accommodate more than one person, likely offering similar or better comfort for multiple users. Since the 2-Panel model clearly states it fits two people, it has a clear advantage for shared use. For the XL model, you must infer capacity based on its larger size.
Red light therapy
Both units include red light therapy, but the configuration differs. The iTHERAU 2-Panel Infrared Steam Sauna Box comes with two independent professional-grade panels, each emitting 660nm visible red light and 850nm near-infrared light. This dual-panel layout provides full-body coverage and is designed to boost circulation and soothe muscle soreness. The iTHERAU XL Infrared Sauna Box includes one professional-grade lamp with 108 pieces of 660nm red light and 216 pieces of 850nm NIR light. While the XL model specifies the number of LEDs, the 2-Panel model emphasizes dual-panel coverage for broader exposure. If you want comprehensive light coverage across your body, the dual-panel setup is a distinct feature.
Heating and steam specs
Both saunas share identical heating specifications, making this a tie. Each unit features a 1200W heater made from high-quality 304 stainless steel. This power level allows both models to fill the interior with heat and steam quickly. Both include a 3L water tank for steam generation and offer remote control operation. You can adjust the temperature across 15 levels and set a timer for 1 to 90 minutes. Safety features are also identical, including anti-dry burning, anti-leakage, explosion-proof protection, and automatic power-off functions. Since the core heating performance and controls are the same, neither product has an advantage here.
Build materials and design
The build quality and design approach vary slightly. The iTHERAU XL Infrared Sauna Box uses a 450D oxford fabric tent with thickened stainless steel piping for rust resistance and durability. It features a clear visualization window and a high-load-bearing foldable chair. The iTHERAU 2-Panel Infrared Steam Sauna Box also uses thickened 450D oxford fabric and stainless steel supports, highlighting superior tear resistance and heat retention. Both include a folding chair, storage pockets, and a top hook for towels. The XL model mentions a pentagonal design for extra space, while the 2-Panel model emphasizes its dual-panel layout. Both are tool-free and portable, but the XL model highlights specific insulation upgrades.
Which iTHERAU Sauna Fits You
Users needing extra standing room
The XL model measures 45 inches long and 35 inches wide. This pentagonal design offers 20% more interior space than standard models. You can sit or stand comfortably without feeling cramped. The larger footprint ensures adequate room for full-body movement during your infrared and steam sessions.
Those wanting dual light panels
This 2-Panel model includes two independent professional-grade red light therapy panels. You get double the therapeutic power with 660nm and 850nm light coverage. This layout provides full-body light exposure combined with steam therapy. It is designed to boost circulation and support muscle recovery effectively.
Buyers preferring a compact footprint
The 2-Panel sauna measures 32 inches wide and 32 inches deep. Its square base occupies less floor space than the XL version. You can easily move it to different rooms. The tent design folds compactly for storage. This makes it ideal for smaller living areas.
