10 Best Portable Infrared Saunas 2025 in the United States

The KASUE Infrared Sauna Box offers a roomy and comfortable sauna experience with its large dimensions (35" x 35" x 71"), making it suitable for most adults who want a full-body session without feeling cramped. It combines infrared heating with steam therapy, powered by a strong 1400W steam generator and a 3-liter capacity, ensuring rapid and even heat distribution. The temperature range is adjustable with nine settings and a long maximum session time of up to 99 minutes, controlled easily via remote, which adds convenience during use.

Its 5-layer waterproof and thermal insulation fabric along with a sturdy stainless steel frame provides good durability and heat retention, while the waterproof base makes cleaning easier. The sauna includes helpful extras like a foldable chair and transparent windows that let you stay connected to your surroundings. Portability is a strong point: it folds down compactly and sets up quickly, ideal for small spaces or moving between rooms.

On the downside, weighing about 19 pounds, it’s not the lightest option if you need frequent transport. Also, while it combines infrared and steam, the product is marketed primarily as a steam sauna, so those seeking a pure infrared experience might find it less focused in that area. This sauna is well suited for users wanting an affordable, spacious, and easy-to-use steam sauna that offers added comfort features, especially at home or casual indoor/outdoor settings.

The RRGFB Far Infrared Sauna Box is a spacious and portable option for those looking to enjoy the benefits of infrared sauna therapy at home. Its large size (nearly 6 feet tall) means most adults can sit or even stand inside comfortably, which is a plus compared to smaller portable saunas that require crouching. The sauna uses carbon crystal heating panels and a heated foot pad to provide consistent warmth up to 140°F, which is within the typical range for effective infrared therapy. The inclusion of red light therapy adds a gentle skin and muscle benefit, making it a nice extra feature for relaxation and circulation.

The sauna’s premium insulation helps retain heat well while potentially lowering electricity use, and its waterproof, easy-to-clean surface adds practical convenience. Setup is straightforward and tool-free, and the unit folds flat for storage, enhancing its portability. On the downside, at about 26 pounds and with dimensions of 35 x 31 x 70 inches when packed, it’s portable but not very lightweight or compact compared to some smaller models, so it might be less convenient for frequent travel.

This sauna is well suited for home users seeking a roomy, comfortable infrared sauna experience with added red light therapy, who value ease of setup and decent heat retention, but it may feel bulky if a more ultra-portable design or higher heat settings are preferred.

The Dynamic Saunas Home Sauna, designed for 1-2 people, stands out with its six Carbon PureTech heating panels that deliver efficient heat, allowing the user to experience the benefits of infrared therapy. This sauna heats from the inside out, which can be particularly beneficial for those looking to relieve stress or improve sleep quality. The temperature range is suitable for relaxation and detoxification, and the interior lighting adds a cozy touch, making it more enjoyable to read or unwind during sessions.

Portability is a key feature here, as this sauna is designed for home use and can fit in various spaces, ideal for individuals with limited room for larger saunas. The Bluetooth capability and built-in speakers enhance the experience, allowing users to enjoy their favorite music while relaxing.

It is important to note that while it accommodates two people, it may be more comfortable for one due to the limited space. The build quality, while decent, may not feel as robust as more expensive models. Additionally, the sauna relies on electricity, which means users need to ensure a proper power source is available. The pricing may also be a factor for some, as it's essential to weigh the cost against the features provided.
