I am replacing a economy shower stall with an uprgrade. Right now I am thinking about obtaining a Dreamline Neo Angle Model # DL61677-FR. My concerns with buying sight unseen are. 1. How stable is the floor? I dont want something that has a "bounce" to it while I am standing in there. 2. Because it is a corner stall, I would like for the corner of the unit to be stable. In other words if I push in on the corner. I do not want it to give there either. I do know that there are showers out there that have the integrity I am looking for but these are all local and do not come in the size I am needing. Hence the internet search.

Also, as far as the walls go, can anyone tell me the difference between Vikrell, Acrylic, or Acrilux?
