Looking Beyond the Smartmak Portable 2 Person Far Infrared Sauna? 6 Alternatives Worth a Look

How each alternative compares

Manastin Portable Steam Infrared Sauna with Red Light

The Manastin model combines steam and infrared heating, whereas the Smartmak relies solely on far-infrared carbon panels. This dual-heat approach allows for adjustable power levels, which suits users who prefer moisture-based warmth over dry heat. It features a 99-minute timer for controlled sessions. However, its interior dimensions are narrower, measuring 31.5 inches wide, compared to the Smartmak’s 35.46-inch width. You sacrifice the dual-seat capacity for a more compact footprint. This option works best for small spaces where you prioritize versatile heating modes and red light therapy over roomy seating for two people.

iTHERAU Portable Steam Sauna with Red Light

The iTHERAU unit shifts from far-infrared to steam and infrared heating, targeting solo users who value rapid warm-up times. It measures 32 inches wide and 71 inches high, offering a vertical profile that differs from the Smartmak’s wider, shorter tent shape. While it includes red light therapy like the Smartmak, it is designed for single occupancy rather than couples. You give up the ability to share the sauna with a partner. This model is ideal for individuals who prioritize quick steam heat and muscle recovery benefits over the spacious, dual-person environment provided by the Smartmak’s 1600W carbon panel system.

SOARFLY 2-Person Infrared Sauna Box

The SOARFLY sauna offers a larger interior, measuring 50 inches long and 75 inches high, providing more room for two people than the Smartmak’s 47.28-inch length. It uses steam and infrared heating instead of pure far-infrared carbon panels. This model includes a folding chair and red light therapy, matching the Smartmak’s comfort features. However, it requires access to two separate electrical outlets due to its dual steam power setup. You gain extra height and width but must manage the power requirements. It is a strong choice for couples seeking a shared steam and light therapy experience with more interior volume than the Smartmak provides.

Noerishia Portable Steam Sauna Box

The Noerishia sauna focuses on solo users with rapid heating capabilities and a remote control, which the Smartmak does not list. It features a 3L water capacity for steam generation alongside infrared heating, differing from the Smartmak’s dry far-infrared approach. The interior is 32 inches wide, narrower than the Smartmak’s 35.46-inch width, making it less suitable for two people. You trade dual seating for precise remote control and faster heat-up times. This option suits individuals who prioritize skin benefits from red light therapy and convenient operation over the shared, spacious environment of the Smartmak’s portable tent design.

Viconor Portable Steam Sauna with Red Light

The Viconor sauna is a compact, single-user option that emphasizes red light therapy and remote control in a small footprint. It uses infrared heating, similar to the Smartmak, but lacks the dual-seat capacity. The listed dimensions are minimal, indicating a design focused on portability and ease of storage rather than spaciousness. You sacrifice the ability to sit with a partner for a simpler, solo experience. This model is best for users who value red light therapy and easy remote operation in a confined space. It offers a streamlined alternative for those who do not need the wider interior or carbon panel heating of the Smartmak.

iTHERAU XL Infrared Sauna Box with Red Light Lamp

The iTHERAU XL sauna combines steam and infrared heating with red light therapy, offering a focused single-person experience. It measures 45 inches long and 73 inches high, providing more vertical space than the Smartmak’s 63-inch height. The interior width is 35 inches, slightly narrower than the Smartmak’s 35.46-inch width. You give up dual seating for a design that prioritizes remote convenience and robust heating specs. This model is ideal for users who want steam benefits alongside infrared heat but do not require the shared capacity of the Smartmak. It serves those who value quick warmth and targeted therapy over spaciousness.
