iTHERAU vs Viconor Sauna Specs
Person capacity
The iTHERAU model is designed for two people, offering a spacious 71 x 49 x 36 inch inner area. This layout allows for side-by-side seating or standing movement without feeling cramped. In contrast, the Viconor unit measures 33 x 33 x 71 inches. Its narrower footprint suggests it is intended for single-user use. While both provide ample height for standing, the iTHERAU’s wider base accommodates partners or friends, making it the better choice for shared sessions. The Viconor’s compact square design prioritizes individual privacy over group comfort.
Heating type
Both saunas combine steam and red light therapy for a comprehensive wellness experience. The iTHERAU features dual 1200W steamers with a 3-liter capacity each, ensuring rapid and uniform heat distribution. It also includes a high-power panel with 160 visible 660nm red light beads and 320 invisible 850nm near-infrared beads. The Viconor uses a single 1200W steam generator with a 3-liter capacity. While it also offers 660nm and 850nm red light therapy, the iTHERAU’s dual-steamer setup and higher bead count provide more intense and faster heating performance for larger spaces.
Control type
Control options differ significantly between the two units. The iTHERAU comes with two smart remote controls, allowing two users to adjust settings independently or share control easily. It supports 15 adjustable temperature levels and a 99-minute timer. The Viconor includes one remote control with 9 precise temperature settings and a timer up to 95 minutes. The iTHERAU offers more granular temperature control and a longer maximum session time. Additionally, having two remotes adds convenience for couples, whereas the Viconor’s single remote and lower setting count limit customization options.
Design and portability
Both units are portable and feature tool-free assembly for easy storage. The iTHERAU has a detachable frame and folds compactly, with a waterproof inner material that is easy to wipe dry. The Viconor is a tent-style design with ultrasonic composite fabrics that trap heat effectively. It includes a soft floor mat to protect surfaces and internal storage pockets for towels or essentials. The Viconor also features ventilation windows for airflow and hooks for hanging robes. These thoughtful additions make the Viconor slightly more user-friendly for quick setup and organization compared to the iTHERAU’s simpler design.
Build and safety
Both saunas prioritize safety and durability with stainless steel frames. The iTHERAU uses a robust stainless steel frame with thickened tubes for stability and a 304 stainless steel inner lining in the steamer. It includes multiple safety protections, such as earth leakage protection, dry heating prevention, and explosion-proof features. The Viconor also boasts a sturdy stainless steel frame that resists deformation. While both models ensure stable construction, the iTHERAU provides more detailed safety specifications, including specific electrical protections and higher-grade inner materials, offering enhanced peace of mind during use.
Choose the Right Sauna for You
Couples or wide-stance users
The iTHERAU model offers a 71 x 49 x 36 inch interior, providing ample space for two people to sit side-by-side. Its wider footprint allows for comfortable standing and stretching without feeling confined, making it ideal for shared sessions or users who prefer extra room for movement during their steam and red light therapy routines.
Small apartment dwellers
The Viconor unit measures 33 x 33 x 71 inches, offering a compact footprint that fits easily into smaller spaces. Its narrow width makes it easier to store or position in tight corners. This shape is practical for users with limited floor space who still want access to 1200W steam and red light therapy without sacrificing too much room.
Users wanting detailed monitoring
The Viconor sauna features a temp and humidity display, allowing you to monitor your environment precisely. It also includes internal storage pockets and hooks for towels. These practical additions help you keep essentials organized and maintain a tidy session, adding convenience to your routine beyond just the heating and red light capabilities found in both models.
