As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
If you are evaluating relax sauna portable far infrared sauna alternatives, you likely value the original’s compact footprint and lightweight design. The Relax Sauna Portable Far Infrared model measures 31.5 inches wide and 31.5 inches deep, with a height of 45.3 inches. It weighs just 26 pounds and features a foldable shape for easy storage. Its patented far infrared generator uses a 7–14 micron semiconductor emitter to deliver heat efficiently. These specs make it ideal for solo users in small apartments who need a portable, low EMF solution.
You might look elsewhere if you need more interior space, dual heating modes, or smart controls. The alternatives listed here overlap with the original’s core specifications, such as infrared heating and portable construction, while offering different capacities or features. Some options include steam capabilities, red light therapy, or app integration. Others provide larger dimensions for couples or corner-friendly shapes for tighter indoor spaces. This list highlights models that share the original’s focus on convenience and infrared technology, giving you clear choices based on your specific size and feature requirements.
How each alternative compares
Durasage DIF-5000 Low EMF Infrared Sauna
The Durasage DIF-5000 shifts focus from a full-body enclosure to targeted seated relaxation. While the Relax Sauna offers a 31.5-inch wide portable box, the Durasage is significantly smaller, measuring just 6.85 inches wide and 2.3 inches high. It includes a heated foot pad and remote control, features the original lacks. This design suits low EMF seekers who prioritize compact storage and foot warmth over full-body infrared coverage. You sacrifice the spacious interior of the Relax Sauna for a highly portable, specialized heating experience that fits easily in tight spaces.
SOARFLY 2-Person Infrared Sauna Box
The SOARFLY unit expands your options by offering dual-heat capabilities and a larger footprint. At 38 inches wide and 50 inches deep, it is wider and deeper than the Relax Sauna’s 31.5-inch square base. It adds steam therapy and red light features, which the original does not provide. The inclusion of a folding chair supports two people, whereas the Relax Sauna is designed for solo use. You gain versatility and capacity but accept a larger physical presence. This alternative fits couples or users who want steam benefits alongside infrared heat in a portable frame.
Noerishia Portable Steam Sauna Box
The Noerishia model introduces steam functionality and a larger interior volume. It measures 32 inches wide and 32 inches deep, slightly larger than the Relax Sauna’s 31.5-inch dimensions, with a height of 71 inches. It includes red light therapy, a remote control, and a folding chair. The 3-liter water tank enables steam sessions, a feature absent in the original. You trade the Relax Sauna’s simpler infrared-only design for a multi-modal experience. This option suits individuals seeking targeted red light therapy and steam in a portable, foldable unit with enhanced control features.
iDOTODO Full Size Portable Infrared Sauna
The iDOTODO sauna offers a vertical infrared design with remote control and a heated foot pad. It measures 33.8 inches wide and 33.8 inches deep, slightly wider than the Relax Sauna, with a height of 66.5 inches. The inclusion of a remote allows for easy adjustments without opening the unit. Like the Relax Sauna, it is designed for solo users with limited space. You gain targeted foot warmth and convenient control but lose the specific 31.5-inch square footprint. This alternative fits users who value quick heating and remote accessibility in a compact, foldable infrared enclosure.
KUNSANA 2-3 Person Corner Hemlock Infrared Sauna
The KUNSANA sauna moves away from portable boxes to a permanent indoor corner unit. It measures 47.3 inches wide and 47.3 inches deep, significantly larger than the Relax Sauna’s 31.5-inch base. It accommodates two to three people and features smart app control, Bluetooth speakers, and chromotherapy. The hemlock wood construction offers durability but removes the portability of the original. You trade the lightweight, foldable design for a stationary, multi-person experience with advanced tech features. This option suits buyers who prioritize indoor placement and group use over easy storage and mobility.
LTCCDSS 3-Person Outdoor Red Cedar Sauna
The LTCCDSS sauna is designed for outdoor use with red cedar construction. It measures 44.9 inches wide and 83.4 inches long, much larger than the Relax Sauna’s compact dimensions. It accommodates three people and includes a recliner, Bluetooth speakers, and low EMF features. The outdoor placement requires yard space, contrasting with the Relax Sauna’s indoor portability. You gain a weather-resistant, group-capable structure but lose the ability to fold and store it easily. This alternative fits users with outdoor space who want full-spectrum heat for multiple people in a durable cedar build.
