We are redoing on master shower (located upstairs) and would like to have a good quality shower pan installed. We currently have an acrylic pan that "gives and groans" and would like one with more stability, etc. I have read that perhaps it isn't the pan at all, but instead, that the pan was not installed correctly. We plan to tile above the pan.

Anyway, after lots of research, I am not sold on any brand or model. Any ideas? We probably would prefer solid surface, but they are so incredibly heavy to get upstairs. Anyone know anything about the solid surface "Better Bases?" Thanks for your suggestions.
