Space and Steam Comparison
Internal dimensions
The iTHERAU offers a significantly wider interior, measuring 71 x 49 x 36 inches. This 49-inch width allows two people to sit side-by-side comfortably or provides ample room for one user to stretch out. The SOARFLY model measures 71 x 32 x 32 inches. While the height is identical at 71 inches, the SOARFLY’s narrower footprint is designed for single users or those who prefer a more compact enclosure. The iTHERAU’s broader base provides more lateral freedom, whereas the SOARFLY focuses on vertical space for taller individuals.
Person capacity
The iTHERAU is explicitly rated for two people, featuring two included chairs and a design that supports side-by-side relaxation. This makes it suitable for couples or friends sharing a session. The SOARFLY is marketed primarily as a single-user unit, with one folding chair included. Its narrower width of 32 inches restricts simultaneous use. If you plan to use the sauna with a partner, the iTHERAU’s dual-chair setup and wider interior provide the necessary space. The SOARFLY is better suited for individual sessions.
Steamer configuration
Both saunas utilize 1200W steamers, but the iTHERAU includes two separate 3L steamers. This dual-steammer setup is designed to deliver stronger, more concentrated steam output and achieve faster overall heating with uniform temperature distribution. The SOARFLY uses a single 3L steamer. While it also reaches 130°F, the iTHERAU’s dual-unit approach suggests a more robust steam generation capability. For users seeking intense, rapid steam coverage, the iTHERAU’s two steamers offer a distinct advantage in power and redundancy.
Red light therapy
Both units feature red light therapy panels with 660nm visible red light and 850nm near-infrared light. The iTHERAU specifies a high-power panel with 160 beads of 660nm light and 320 beads of 850nm light. The SOARFLY also includes a professional red light panel with the same wavelengths but does not specify the number of beads or total power output for the light therapy component. Both aim to promote circulation and skin rejuvenation, but the iTHERAU provides more detailed specifications regarding the density of the light emitters.
Control interface
The iTHERAU comes with two smart remote controls, allowing each user to independently manage temperature and timing. It supports 15 adjustable temperature levels and a 99-minute timer. The SOARFLY includes a single remote control with 9 temperature adjustment settings and a similar 99-minute timer. The iTHERAU’s dual remotes and higher temperature granularity offer more flexibility for shared use. The SOARFLY’s single remote is sufficient for individual users but limits independent control in a two-person setting.
Insulation and build
The iTHERAU is constructed with a premium five-layer composite waterproof material designed to lock in heat and block steam leakage. It also features a robust stainless steel frame and 304 stainless steel inner lining for durability and safety. The SOARFLY uses a three-layer waterproof cotton fabric with a tent-style design. While the SOARFLY includes a transparent zipper window and external storage pocket, the iTHERAU’s multi-layer insulation and metal frame suggest a more rigid and heat-retentive structure. The SOARFLY’s fabric build is lighter and potentially easier to store.
Choose the Right Sauna for You
Couples seeking shared relaxation time
The iTHERAU model features a 49-inch width, allowing two adults to sit side-by-side comfortably. It includes two chairs and dual 1200W steamers for uniform heating. This spacious 71 x 49 x 36-inch interior ensures ample room for shared sessions without crowding, making it ideal for partners.
Tall users prioritizing legroom
The SOARFLY sauna has a 71-inch height, accommodating users up to 6 feet 7 inches. Its 32-inch width and depth provide a compact footprint while allowing you to stretch your legs fully. The design supports standing or sitting, ensuring comfort for taller individuals who need vertical space.
Users wanting simple controls
The SOARFLY unit offers a straightforward remote control with nine temperature settings and a 99-minute timer. It heats up in six to ten minutes and reaches 130°F. The simple interface and external storage pocket for small items make operation easy and convenient for daily use without complex adjustments.
