Sunlighten saunas are very hazardous! I purchased one for my tanning salon and it has caught on fire 6 times where flames hsoot out of the mesh heaters. Yes it extinguishes itself, but if anyone had been laying in the sauna they would have been burned very badly. Fortunately, no one has been hurt though we have had frightened clients who will no longer use our sauna. They refuse to return the sauna and keep sending techs out to fix the issue, that only keeps happening over and over. We are on our 6th time now! DO NOT BUY A SUNLIGHTEN SAUNA WHATEVER YOU DO!!!
