Recently purchased a Rainelle four person sauna and it is fantastic! I am very particular about things and the wood panels were strong and thick. The instructions were right on the money and when my helper didn’t show up to assemble it, I put it together in four hours with absolutely no help! I always want everything right now and so I didn’t wait for more help to show. Turns out, I didn’t need it. The sales people were all knowledgable about their product and was like talking to family. What a treat! Very satisfied with the 6 KW Harvia electric heater that came with this unit and so far it heats up the sauna fast esp with the nice timer included. Almost Heaven has thought of everything on these products and would highly recommend them if you are looking for one.
