10 Best Portable Saunas 2025 in the United States

The KASUE Upgraded 2 Person Sauna Box is a spacious and thoughtfully designed portable infrared sauna that comfortably fits two people, measuring 71" x 49" x 36". It uses dual steam generators to quickly fill the sauna with warm, enveloping steam, offering an efficient heating experience. A standout feature is the inclusion of 660nm red light therapy, which goes beyond typical saunas by helping soothe muscle soreness and support recovery after exercise.

The sauna is made with a 5-layer waterproof and insulated material that keeps heat in well, making sessions more effective while the surface stays easy to clean. Portability is a strong point here: the sauna folds flat, includes lightweight chairs, and comes with a remote control to adjust temperature and time easily. It also has a handy storage pouch and a transparent window that can be opened for fresh air, adding to the comfort and convenience during use. Weighing about 28 pounds, it’s manageable to move and set up indoors or outdoors, making it suitable for home, gym, or spa use.

While it offers ample space and features for two users, it may take some time to get used to the setup process if you’re new to portable saunas. Many users find it to be a great choice if you want a roomy, portable option with extra health benefits like red light therapy and fast steam heating, ideal for sharing relaxing sessions with a partner.

The KASUE Infrared Sauna Box is a solid choice if you're looking for a portable sauna that combines steam and infrared therapies for a deep detox and relaxing experience at home. Its 3-liter steam generator heats quickly and evenly, with 9 temperature options up to 99 minutes, allowing you to tailor your session easily via remote control. The sauna tent is quite roomy at 35"x35"x71", making it comfortable for most adults and even offering a waterproof folding chair for added comfort.

Its five-layer waterproof and insulated fabric along with a sturdy stainless steel frame ensures durability and safety during use. Setup is straightforward, taking just a few minutes and folding down compactly for storage, which is ideal for small spaces or taking it outdoors. Some users might find the sauna's weight near 19 pounds a bit heavy for frequent moves. However, the transparent windows allow you to stay aware of your surroundings, enhancing convenience.

This sauna is well suited for those wanting a reliable, easy-to-use, and spacious portable option for home spa sessions without the need for professional visits.

The LifePro Portable Sauna offers a convenient way to enjoy steam sauna sessions at home. It is a steam-type sauna with a tent design that measures about 35 by 35 inches and nearly 75 inches tall, comfortably fitting one person seated on the included folding chair. The 1200W heating element heats quickly and allows you to choose from 15 temperature levels, adjustable via a remote or smartphone app, which adds ease to controlling your session. The temperature range and timer (1 to 60 minutes) give good flexibility for different preferences. A standout feature is the built-in red light therapy panel, which uses specific wavelengths believed to enhance wellness, making this more than just a steam sauna.

The sauna tent itself is made from insulated, waterproof materials helping it retain heat effectively, and it comes with useful extras like a mat, steam diffuser, and a waterproof phone holder. Setup is straightforward with stainless steel poles and quick connectors, and the unit is lightweight and foldable, making it easy to store when not in use—ideal for apartments or small spaces. On the downside, being a tent-style steam sauna, it requires a flat indoor space and some assembly each time you want to use it, which might be less convenient than permanent saunas. Also, the size limits it to single-person use, so it’s best suited for individual wellness sessions rather than group use.

This portable sauna blends good heating control, portability, and added red light therapy, making it a solid choice for anyone looking to relax and improve wellness from home without needing a bulky or permanent sauna setup.
