Purchased this semi-frameless showertub door to replace our 28 year old one that came with the house. The 90 lb box arrived via FedEx in a well packaged box. Once I unboxed and cut to size (2 off the bottom rail  top track) I was surprised how sturdy everything felt. The door frame is built solid and gave the modern look we were going for. My kids now want this same one in their bathroom, so might have to order another one!
