Steam Generator

Anyone have further feedback on the Kohler or any other Steam Generators. SO many mixed reviews in the marketplace. Thanks. Tom from Hawaii.

Thank you for your inquiry. Kohler Steam Generators are great, however it is important to read through and follow the instructions carefully. Any deviation from the recommended installation may cause frustration and problems during use. Customer’s that have not followed the instructions have contacted Kohler Co. with difficulties during use.
