We embarked on building a bathroom in our basement - a first for us. After exhaustive reading of shower door reviews, the Infinity-Z appeared to be the clear winner. A big part of our decision came from reading that customer support was readily available - this could be important for a DIY project. Not having previous experience to compare to, the installation went smoothly for us - no need to contact customer support. It was definitely a 2-person job for us novices. The finished product is a very attractive door that glides smoothly in it's track without any escape of water. We are very happy with our selection of this door.
