How difficult is this product to install or build???

The infrared saunas come as a kit that is ready for quick assembly. There is a floor panel, wall panels, a ceiling panel, male/female electrical connections, all designed for the homeowner to easily assemble in an hour or two. For some nice ?assembly progress? photos from actual customer, please see the Customer Photos page, which is found in the top horizontal brown menu. http://www.saunasandstuff.com/sauna-customer-pictures-and-reviews/
