I put the enigma x 2 wall shower door system in our fully remodeled master bath. The job was probably my biggest renovation challenge except our kitchen, and the DreamLine shower door system is one of the highlight features.
It is very well made. A little intimidating and you must follow the instructions as others mention. Also, as the instructions say, make sure yours and floor are plumb and level.
I think I read the instructions 10 times before starting, but it was worth it. Th hardware is top grade, and there are no short cuts, or cheap materials. I would buy this product again. I am not professional contractor but I am comfortable with most DIY.
