I've been wanting to build one for a while but I see so many pre-owned infrared saunas available on the cheap. Any consensus if it's just as good? The article references one study that used infrared that reported positive effect.
Bought a 3 person infrared sauna (through Costco) for about 1600$ 12 years ago.
There were periods we didn't use it but generally at least a couple times a week.
Gets you hot, helps you sweat, can be relaxing in itself.
But it's not same 'experience' as a traditional sauna.
I would probably say it was one of the best purchases I have made based on how much we used it, still running strong, has definately helped us over the years.
