When considering the purchase of a modular steam shower it is important that you research the brand and manufacture of the shower you plan on purchasing. Not all steam showers are constructed the same way and the market has been plagued with cheap low quality modular steam showers. You can typically find these steam showers through venues like amazon and ebay. If you are planning on purchasing a steam showert its best to go through a legitamate dealer. This will not only ensure you get a quality unit but also you will have the after sale service and warrany protection. Many sellers who use these venues to sell their products offer the manufacturers warranty. The only problem with this is steam showers are an imported product and many manufacturers do not have customer service capable of service U.S. customers. It is also important to make sure the steam shower you purchase is ETL certified. This will ensure that it complies to the electrical standards of North America.
