Because of the quality construction of our Health Cabins and our far infrared heaters we offer a life-time warranty on both our heaters and our cabins. Our saunas are constructed so that it is very easy for our customers to replace our heaters if ever needed. You do not have to ship the entire sauna back to our warehouse at your expense. We simply send you the part needed and you replace it. It really is that easy! If you should have any problem with it we simply send you a new control. All of our electrical connections are color coded. All you have to do is unplug the old one and plug in the new one. Once again you do not need to send the entire unit back to the warehouse. Our supplier has been in business for 30 years and service is very important to us. Our health Cabins are the best on the market and we will be here for you in the future.
