Beautiful wood finish and fully certified!

I've been cautious about buying an infrared sauna online, but the official FCC and ETL certifications on the DUO model convinced me it’s a premium and safe product. The Red Cedar-Tone finish is stunning. Arrived in 2 boxes, assembly was a breeze, and it heats up so evenly with the 6 carbon panels.

Arrived safely in 2 boxes – Easy setup.

Shipped in 2 sturdy boxes. The 6mm tempered glass door arrived intact. Assembly went smoothly. The 120V/20A dedicated circuit provides consistent performance.

Quality confirmed at a US trade expo!

Discovered this brand at a US wellness expo. The DUO hits the sweet spot between footprint (47 x 41.3 in) and 2-person comfort.

Best 2-person sauna value!

Excellent value for a 2-person sauna with heated floor, red ambient light, and Low-EMF design. Make sure to have your 120V/20A dedicated circuit ready before the 2 boxes arrive!

Great 2-person sauna with top safety standards.

We wanted a 2-person sauna that didn't compromise on electrical safety. The DUO holds both FCC and ETL certifications, which is exactly what we were looking for. It runs flawlessly on our dedicated 120V/20-Amp circuit. The red ambient lighting and low-EMF panels make it our favorite relaxation spot.

Solid build and 6mm glass door.

Low-EMF safety & spa atmosphere.

Low-EMF technology was a key reason we chose the DUO. Knowing our sessions are safe gives us confidence. The 6 carbon panels distribute heat evenly.

Our favorite evening routine!

We use the DUO model every night. The red ambient light helps unwind before bed. Heated floor is the cherry on top! Requires a 120V/20A dedicated circuit, but worth it.

Spacious and efficient for 2 people!

The DUO model was the best choice for my wife and me. Exterior dimensions (47.0 x 41.3 x 75.0 in) provide a generous interior (43.5 x 37.6 in). Set up a dedicated 120V/20A circuit, and the 6 carbon panels heat up super fast.

Saw these at a US sauna show – The DUO is top notch!

Saw these saunas at a US trade show earlier this year and was amazed by the build quality. Canadian Hemlock with Red Cedar-Tone looks gorgeous. Heated floor and red light make every session special.

I bought this sauna mainly because I wanted an easy way to unwind after workouts without having to leave the house. I’ve been using it a few times a week and honestly, it’s become one of my favorite parts of my routine. It heats up quickly, the controls are simple, and the heat feels much more comfortable than a traditional sauna. I usually sit in it for 30-40 minutes while listening to music or a podcast. Really happy with the purchase so far.

I can absolutely say this sauna has been one of the best investments we've made for our home. My husband and I have been using it several times a week, and it has quickly become part of our routine. It was surprisingly easy to assemble, heats up quickly, and feels incredibly relaxing after a long day or a workout. We've both noticed better sleep, faster muscle recovery, and just an overall sense of well-being. The quality is excellent, and the two-person size is perfect for enjoying it together. We couldn't be happier with our purchase and would highly recommend it to anyone considering a home sauna.

This sauna is exactly what I needed. It is comfortable, easy to use, and very relaxing. I use it regularly and I can really feel the difference. The whole buying experience was smooth, and I would definitely recommend Monolight to anyone looking for a good infrared sauna.

Frequently Asked Questions

 Where is the best place to install my new infrared sauna?

The infrared sauna must be installed on a completely level surface.

It is best placed indoors, such as in a bathroom or pool area. It can also be placed outdoors, but only in fully covered areas (like a deck, terrace, or balcony) to protect it from rain and moisture and to maintain the naturally untreated Canadian Hemlock finish.

Maintenance is incredibly simple. Only use a damp cloth for cleaning.

Do not use liquid cleaners, aerosol cleansers, or chemicals on the interior or exterior, as they will damage the wood and its inherent natural protection layer.

We also recommend placing one or two towels on the bench to absorb sweat during your session.

No. The Monolight Duo indoor sauna room is not waterproof.

Please do not spray water inside, and keep all liquids away from the heating panels to prevent damage and avoid the risk of electrical shock.

Yes. The sauna requires a 110V, 14A connection with a standard America plug.

For safety and optimal performance, do not plug any other appliances into the outlet sharing with the infrared sauna.

Yes. Persons with health conditions, those using medications, and pregnant (or possibly pregnant) women should consult their physicians before using the sauna.

Children should only use the sauna if closely supervised at all times.

Additionally, please remove all jewelry before entering , and never sleep inside the sauna while the unit is in full operation.
