Cedabrook Sauna only uses cedar for our saunas
We specialize in western red cedar and do not have other wood species options at this time. Often the subject of phenols and cedar as being unfavorable/allergenic in the sauna environment is more of a talking point than a real world issue. We have supplied cedar sauna rooms to people with high levels of chemical sensitivity with no real world complications.
Of course, it is possible that individuals can have issues with cedar … usually this is topical on the skin’s surface and can be avoided by sitting on a towel. Also note that we sell an all natural water based sealer for saunas that forms a thin breathable layer of glass (silicon quartz based emulsion) over the wood which create a layer of protection between the bather and the wood. Not to mention, it keeps the wood looking pristine for years. I hope you find this helpful in your decision making process.
