Brilliantly, the air between the fiberglass lining and the wood exterior is super-heated to accelerate the heating process. The stove is cleverly engineered to draw cooler water through a lower channel and redistribute it though an upper channel to equalize the temperature.

Let customers speak for us
Great product. The real deal quality and fit. Easy to install. Only four days and so many positives in our family’s life. Im stoked. Recommend to anyone with pain, stiffness, weight gain, high bp ect ect the list is long.
If you’re tight on space, but want to buy a quality infrared sauna, this is the one! Setup took roughly 30 minutes. The build is great and the performance is great too.
This is our second spa we have purchased and by far this is the best.
The infrared heats up the sauna so much faster - save on energy prices just by limiting the warm up.
Solid construction and cover optional cover purchase fits very nice.
Easy to put together - need someone when initially putting side and front together to “hold side” as you put front on
Then it can be done by one person.
Glad we purchased this 3 person full spectrum unit from calm spas- good service thru out

This sauna is well built. Easy to assemble. Easy to operate
We couldn't be happier with CalmSpas and our Lugano 3! CalmSpas helped us through the selection process and were very responsive before and after our purchase. Also, the Lugano was super easy to assemble and looks fantastic…exactly as advertised and better than we expected. If anyone is interested in a sauna, I’d recommend CalmSpas and the Lugano, no question!!
Works great! A quality design and appearance...Heats up well and simple to use. A winner.
Backrests make leaning against the wall much more comfortable
Perfect fit, looks great, fantastic customer service.

I have worked as a dealer of commercial furniture for the past 24 years and can tell you that this is a quality piece of furniture for what it is. From the time it arrived at my business, loaded on a pallet, we could tell the attention given to packaging alone. No issues with freight. Once I reloaded it and brought this to my home, I began to unpack it and found that everything inside the boxes was also packed very well. The box with the glass walls and doors even had plywood across one section of the box to protect the glass pieces. The installation was very easy once all the pieces were unpackaged. The idea that it would basically snap together was daunting but the alignment of these pieces was perfect and felt very tight once completed. The arrangement of the wiring was also very easy to fit together and everything worked as it should. So that is my summary of the quality.
As for the unit itself and how it worked...it was as good or better than the larger unit we often visit at a wellness center. We hooked up the bluetooth speakers to an Alexa and they sync as soon as we turn the unit on. We let it warm up for about 10 minutes and do not enter the unit until it has reached at least 100 degrees. Then we can sit while the unit continues to heat and let it do it's thing.
We are currently advising a couple of family members to how well we liked our unit.

This Golden Design full spectrum sauna is very nice. My wife and I were able to put it together in an hour or two. Most of that time was unpacking the parts.
It warms up quickly, quicker than expected after reading some reviews. We mostly use it after a workout so sweating starts after the temp reaches 100° or so. We set it at the recommended setting of around 130°.
We use it daily and hope to see and feel the benefits soon. It is my quiet space to read for 30 minutes at a time.
The specs say 1 or 2 person sauna. We haven’t tried fitting 2 in at a time and don’t intend to. There wouldn’t be room to move around at all.
The Cordoba Sauna was the least expensive, full spectrum sauna with the ability to plug into a standard 15 amp circuit. Specs say use a 15 amp dedicated circuit, but as long as nothing else is plugged in and turned on any receptacles in the circuit, it is fine.
We're very happy with our Mspa Duet, it has exceeded our expectations! And the customer service at CalmSpas was top notch, I would highly recommend purchasing from them!!
Love the sauna, room enough to install a traditional style heater for steam option and still fit 3 to 4
Bought this instead of some of the other brands that we're twice as much. Once I did a little research, I found out the more expensive brands were just shipping there product strait from a Chinese factory. I decided if I was doing to by Chinese I would by the cheaper one and I'm glad I did. It's not the best quality, but with a little insulation on the roof it heats to 180 in about 30 minutes. It took my wife and I about 2 hours to assemble. We put it on are covered porch outside and had an electrician hook up a 30 amp breaker. Friend's have commented how nice it looks. We're very happy!
