Second near infrared sauna choice....

Next I found this:

It's called the "Turbo Sauna" and it is designed to convert a bathtub/shower area into a near infrared sauna. It comes with the heater shown, and a kit to hang a canvas to make a ceiling over your shower door. It has a fan built in and a sensor to prevent over heating. Although, if the bulbs weren't recessed into the housing, they wouldn't need the fan or the sensor.


It seems very straight forward. The site is nice. Here are some pics of the installation in a tub with the hanging canvas.


   





Price: $699 plus shipping. 


My questions about this sauna are (1) It looks like the housing is stained plywood. The site doesn't say but I am, pretty sure the shelf it sits on is made  plywood. (2) How big a shower is this rated for. 


Has anyone out there tried this one? What do you think?
