I purchased two doors for the renovation of my bathrooms. The quality of merchandise purchased is unsurpassed. I am really enjoying the installed door. I may have overlooked some information about installation because the Dreamline product came highly recommended by my daughter and also by a friend. I did not know the difficulty I would encounter to get them installed. Had I known, I would have investigated further to learn who would be able to install for me, since I am not able to complete installation myself, as well as, the cost for a professional installation. I am still awaiting the completed installation of the second door due to glass storm damage in the area where a professional is needed for repairs.
