Does anyone know about the integrity of the Dreamline Shower Stall?

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?

 

Most of today's shower pans and bathtubs should be set in a bed of mortar to make them feel solid. Many will specify this in the installation instructions as a good option.

I know nothing about the shower you are looking at. There is a lot of flimsy junk on the market.

I recently installed a Sterling (Kohler) Ensemble 60" shower in a mortar bed and am very happy with it so far. It is the Vikrell material.
