6 Best Alternatives to the iTHERAU 2-Person Portable Steam Sauna (2026)

How these saunas differ from iTHERAU

Noerishia Portable Steam Sauna Box

The Noerishia Portable Steam Sauna Box uses a similar steam and infrared setup with red light therapy. It shares the foldable design and includes a remote control and folding chair. Its main difference is the gray color option, which contrasts with the iTHERAU’s jet black finish. The Noerishia unit has a 3L water capacity, matching the iTHERAU’s dual steamer efficiency. You get comparable heating power in a compact form. This alternative suits you if you prefer a neutral gray aesthetic or want a slightly different footprint. It maintains the core benefits of shared steam therapy while offering a distinct visual style. The remote control ensures easy temperature and timer adjustments, keeping the user experience familiar and convenient.

Viconor Portable Infrared Steam Sauna Tent

The Viconor Portable Infrared Steam Sauna Tent offers a complete kit similar to the iTHERAU, including red light therapy and a folding chair. It shares the dual heating type of steam and infrared. The key difference is its tent-style design, which may appeal to those seeking a lighter, more temporary structure. It targets users in compact spaces who do not need smart app features. The Viconor model provides a practical, portable solution without the extra bulk of a rigid frame. You get essential red light benefits and steam heating in a foldable package. This option is ideal if you prioritize portability and ease of storage over a larger, more permanent sauna box. It delivers the core wellness features in a streamlined, budget-friendly format.

SOARFLY 2-Person Infrared Sauna Box

The SOARFLY 2-Person Infrared Sauna Box provides a spacious interior with dual heating modes. It shares the steam and infrared combination with red light therapy. The main advantage is its larger footprint, measuring 50 inches in length and 38 inches in width. This offers more room for two adults compared to the iTHERAU’s 71x49x36 dimensions. It includes a folding chair and remote control for convenience. The SOARFLY model is available in pink, offering a color alternative to the iTHERAU’s black. You gain extra space for stretching or sitting comfortably. This choice fits buyers who prioritize physical roominess and red light benefits. It delivers a premium experience with ample interior volume for couples or users who dislike confined spaces.

Smartmak 2 Person Portable Steam Sauna Box

The Smartmak 2 Person Portable Steam Sauna Box features a compact design with a 1500W heater and 4L capacity. It shares the steam and infrared heating types with red light therapy. The Smartmak model is smaller, measuring 33.9 inches square, making it ideal for tight indoor spaces. It lacks a folding chair but includes remote control functionality. The 1500W power output provides quick heating, comparable to the iTHERAU’s dual steamers. You get a focused steam and light combo in a smaller footprint. This alternative suits users who value quick heating and compact storage over spacious interiors. It is a practical choice for those who want essential red light benefits without the bulk of a larger sauna box. The compact size makes it easy to store when not in use.

ABSCONDO Portable Infrared Sauna Box with Red Light

This alternative is ideal for those with limited space who still want steam and infrared therapy. It maintains the core wellness features while offering a more compact and portable option. The remote control ensures easy adjustments, keeping the user experience simple and convenient. It is a practical choice for small apartments or rooms.

SOARFLY 71 in Infrared Steam Sauna Box

The SOARFLY 71 in Infrared Steam Sauna Box offers a tall, narrow design for taller users. It shares the foldable design and includes red light therapy and a folding chair. The key difference is its height, which reaches 71 inches, providing more vertical space. It lacks steam heating, using only infrared, which differs from the iTHERAU’s dual steam and infrared setup. The 3L water capacity is present, but the heating type is distinct. You get a portable steam sauna with a remote control for taller individuals. This choice fits buyers seeking a portable infrared sauna with a folding chair. It is ideal if you prioritize height and infrared benefits over steam heating. The narrow footprint makes it suitable for spaces where width is limited but height is available.
