The iTHERAU 2-Person Infrared Sauna Box combines steam and red light therapy in a spacious enclosure. If you are looking for itherau 2 person infrared sauna alternatives, this guide highlights options that share similar heating technologies or capacity. The original model stands out for its dual 1200W steamers and large 71 x 49 x 36 inch interior. It also includes a 160-lamp red light panel for cellular rejuvenation alongside detoxifying heat.
You might want a different sauna if you need a smaller footprint or a different price point. Some alternatives offer more compact dimensions for tighter spaces. Others focus on specific features like low EMF emissions or tent-style portability. We selected these 6 products because their specifications overlap with the original. This includes shared traits like infrared heating, red light therapy, and two-person capacity. Each option provides a distinct combination of size, material, and control type to match your specific home setup.
How each alternative compares
SOARFLY 2-Person Infrared Sauna Box
The SOARFLY 2-Person Infrared Sauna Box offers slightly larger dimensions at 75 inches tall and 50 inches long compared to the iTHERAU’s 71 by 49 inches. It retains the dual steam and red light therapy approach, making it a strong match for couples. However, it lacks the specific remote control details listed for the iTHERAU model. You get a folding chair feature and a portable design, similar to the iTHERAU. If you prefer a bit more vertical space and do not need the explicitly stated smart remote controls, this is a viable premium alternative.
iDOTODO 2 Person Portable Infrared Sauna
The iDOTODO 2 Person Portable Infrared Sauna is notably more compact, measuring 63 inches high and 47.2 inches long. It weighs only 36.8 pounds, making it much lighter than the iTHERAU. It includes red light therapy and a remote control, which aligns with the iTHERAU’s feature set. The trade-off is reduced interior volume. This model suits users with limited floor space or those who prioritize quick setup and portability over the generous standing room found in the iTHERAU. It is a practical choice for smaller apartments.
SOARFLY 71 in Infrared Steam Sauna Box
The SOARFLY 71 in Infrared Steam Sauna Box is significantly narrower, at 32 inches wide and 32 inches long, compared to the iTHERAU’s 49-inch width. It maintains the dual steam and red light heating type. It includes a 3L capacity and a folding chair. This model sacrifices the spacious two-person comfort of the iTHERAU for a more compact footprint. It is best for users who want dual therapy benefits but have tight space constraints. It fits single users or couples who do not need extra lateral room.
CedarLuma 2-Person Low EMF Infrared Sauna
The CedarLuma 2-Person Low EMF Infrared Sauna focuses on low EMF emissions and red light therapy. It measures 63.3 inches high and 31.5 inches wide, which is smaller than the iTHERAU. It weighs 188 pounds, indicating a more substantial build. Unlike the iTHERAU, it does not list steam functionality, relying solely on infrared heat. This option suits users who prioritize certified low EMF levels and red light benefits over the combined steam experience. It is a specialized choice for health-conscious buyers sensitive to electromagnetic fields.
UNANEST Portable Steam Sauna with Clear Door
The UNANEST Portable Steam Sauna with Clear Door is designed as a tent rather than a rigid box. It measures 70 inches high and 31 inches wide, offering less space than the iTHERAU. It combines steam and infrared heating with red light therapy. The clear door provides visibility, a feature not mentioned for the iTHERAU. This model is ideal for solo users in small apartments who want portability and a view. It gives up the two-person capacity and sturdy frame of the iTHERAU for a more flexible, tent-style setup.
SAN HIMA 2 Person Steam Sauna Box
The SAN HIMA 2 Person Steam Sauna Box lists a size of 36.6 inches long and 18.1 inches wide, which appears to be a compact or folded dimension. It supports 2-3 person capacity and includes red light therapy. It focuses on steam heating rather than the infrared blend of the iTHERAU. This model prioritizes quick steam sessions and portability. It lacks the detailed remote control and insulation specs of the iTHERAU. It is suitable for users who want fast steam heat and red light benefits in a portable format, accepting a different heating technology.

Frequently asked questions
Which alternative offers the largest interior space for two people?
The SOARFLY 2-Person Infrared Sauna Box provides the most generous dimensions among the listed options. It measures 75 inches in height and 50 inches in length. This layout offers more vertical room than the iTHERAU model, which stands at 71 inches tall. You gain extra headroom and a slightly longer seating area for comfortable stretching during your session.
Can I use steam therapy with these infrared sauna alternatives?
Yes, several models combine infrared heating with steam functionality. The SOARFLY units and the UNANEST tent both support dual steam and infrared heating. This allows you to adjust humidity levels for a softer heat. The iTHERAU and CedarLuma models focus primarily on infrared emission, so they do not include built-in steam generators for moisture-based sessions.
Which option is best for small apartments or limited floor space?
The iDOTODO Portable Infrared Sauna is designed for compact environments. It weighs only 36.8 pounds and features a detachable frame for easy storage. The UNANEST tent is also suitable for tight spaces, as it occupies a small footprint. These models prioritize portability and quick setup over the permanent installation required for larger box-style saunas.
Do these saunas include red light therapy features?
Most alternatives in this list include red light therapy panels. The iTHERAU, SOARFLY, iDOTODO, CedarLuma, and UNANEST models all feature this specific light therapy. Red light panels are typically embedded in the interior walls. This feature allows you to receive targeted light exposure while undergoing heat therapy, supporting skin health and muscle recovery simultaneously.
Is there a model that includes a remote control?
The iDOTODO 2-Person Portable Infrared Sauna includes a remote control for operation. This allows you to adjust settings without opening the enclosure. Other models like the SOARFLY and CedarLuma do not list remote controls in their specifications. You may need to interact with the control panel directly on the unit for those specific brands.
Which sauna is the most portable and lightweight?
The iDOTODO model is the lightest option at 36.8 pounds. Its foldable design and low weight make it easy to move or store. The UNANEST tent is also highly portable, though it relies on a steam generator. Heavier options like the CedarLuma weigh 188 pounds, requiring more effort to relocate or set up in a fixed location.
Are there low EMF options available as alternatives?
The CedarLuma 2-Person Infrared Sauna is specifically marketed as a low EMF model. This design minimizes electromagnetic field exposure during use. Other models in the list do not explicitly state low EMF certification in their provided specifications. If minimizing electromagnetic exposure is a priority, the CedarLuma option offers verified safety standards for this specific concern.
