Gratelakes, I have not used the sauna for a lot of clients yet...I really just came up with the idea of using it for clients recently, but I have started promoting it and so I'll try to update this thread as I get more people to try it out.
As for the Sunlight Sauna "portable" sauna, which fits over the table, I decided not to get it simply because of space issues. It's a big tube, and even collaped together, it still would take up too much space in my treatment room. I can fold my little sauna up and tuck it behind a chair.
As for cleaning, I basically line the thing with towels, which get changed after use. The towels go over the chair (folding chair that fits inside), the foot heater, and the "neck" hole where your head sticks out. Basically, no part of your body touches the unit directly. I bought the xlarge size (which is what the seller was recommending to handle most body sizes). I don't think that even tall people would have a problem.
The unit is basically silent. No fan. Just amazingly soothing heat. (Mmmmm...will have to go down and sit in mine shortly!
) I don't think it heats the room up too much, but then again I probably won't be using it too much as the weather gets warmer. Preheating takes just minutes...maybe five minutes or less. That's one of the best things about it. There is a timer that you can set for up to half an hour.
Now, don't get me wrong..like holmslm57, I'd be getting a nice large wooden FIR sauna if I could, and if it made sense for me to do so in my present location, and I do like Sunlight Saunas, but I still think that the portable sauna I have is a great solution for what I want now. Especially if I ever bring it along on an outcall.
Good luck on whatever you choose, though. Infrared saunas are awesome! See ya...I'm gonna go sweat now!
