Thank you for your purchase and your review, Skip! You are absolutely correct that professionals should install this shower door, and in fact, DreamLine recommends that our shower doors be installed by professionals due to the size, weight and fragile nature of the product. Most general contractors with bathroom remodeling experience are more than capable of installing DreamLine Shower Doors. DreamLine also maintains a list of Certified DreamLine Installers. Depending on what area of the country you live in, there may be a Certified DreamLine Installer near you! We thank you again for your purchase and for taking the time to write a review about your Elegance Shower Door.
