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

How each alternative compares

SAUNABOX SmartSteam Pro 1-Person Steam Sauna

The SAUNABOX SmartSteam Pro targets solo users with a compact footprint of 12 x 12 x 40 inches. It sacrifices the spacious interior of the Smartmak, which measures 47.2 x 35.4 x 63 inches, for portability and app control. Both units provide steam heating and red light therapy. You get a more focused recovery experience with the SAUNABOX, but you lose the room to accommodate two people. This model suits individuals who prioritize smart features and easy storage over shared sauna time. The smaller dimensions make it easier to set up in tighter spaces, though it lacks the open view windows found on the Smartmak tent.

Manastin Portable Steam Infrared Sauna with Red Light

The Manastin unit offers dual heating with both steam and infrared options, whereas the Smartmak relies solely on steam. It is designed for two people and includes red light therapy. The Manastin dimensions are 70.9 x 31.5 x 31.5 inches, providing a different spatial layout compared to the Smartmak’s 47.2 x 35.4 x 63 inches. You gain versatility in heating methods and potentially lower cost, but you give up the specific transparent window design and double-pocket features of the Smartmak. This alternative fits users who want manual control and combined heat types in a compact package. It is a practical choice for those who value heating flexibility over the specific ventilation features of the original model.

iTHERAU Portable Steam Sauna with Red Light

The iTHERAU Portable Steam Sauna combines steam and infrared heating, offering more thermal variety than the Smartmak’s steam-only approach. It includes a folding chair and red light therapy. The interior dimensions are 32 x 32 x 71 inches, which is narrower but taller than the Smartmak’s 47.2 x 35.4 x 63 inches. You get a seated experience with dual heating modes, but you lose the standing room and wider base of the Smartmak. This model suits users who prefer manual control and included seating. It is a solid option for those who want infrared benefits alongside steam, though it does not match the Smartmak’s footprint for two people standing comfortably.

SOARFLY 2-Person Infrared Sauna Box

The SOARFLY 2-Person Sauna provides dual steam generators for stronger heat output, unlike the single-source steam of the Smartmak. It includes red light therapy and a folding chair. The dimensions are 50 x 38 x 75 inches, offering a taller and wider interior than the Smartmak’s 47.2 x 35.4 x 63 inches. You gain more height and powerful heating, but you give up the transparent windows and double-zipper access of the Smartmak. This unit fits buyers who have two electrical outlets and want a remote-controlled experience. It is best for those prioritizing heat intensity and extra space over the specific visibility and entry features of the original model.

Noerishia Portable Steam Sauna Box

The Noerishia Portable Steam Sauna features remote control operation and a 3-liter water capacity, differing from the Smartmak’s manual setup. It includes red light therapy and a folding chair. The dimensions are 32 x 32 x 71 inches, which is narrower than the Smartmak’s 47.2 x 35.4 x 63 inches. You get adjustable settings and quick heating control, but you lose the spaciousness and open-view windows of the Smartmak. This model suits users who prioritize convenience and precise temperature management over roomy interiors. It is a compact choice for those who want remote functionality, though it does not accommodate two people as comfortably as the wider Smartmak tent.

iTHERAU XL Infrared Sauna Box with Red Light Lamp

The iTHERAU XL Infrared Sauna Box offers dual heating with steam and infrared, providing more options than the Smartmak’s steam-only system. It includes red light therapy and a 3-liter capacity. The dimensions are 45 x 35 x 73 inches, which is taller but slightly narrower than the Smartmak’s 47.2 x 35.4 x 63 inches. You gain durable construction and combined heat types, but you give up the transparent windows and double-pocket design of the Smartmak. This model fits users who value manual remote control and robust build quality. It is a strong alternative for those seeking enhanced heating versatility, though it does not match the specific ventilation and storage features of the original Smartmak design.
