I'm getting ready to renovate the Master Bath. Currently, there is a one-piece fiberglass insert for the shower. I'll be building a half wall and installing a frameless door/wall for the new shower enclosure. The glass installer suggested I use a Tile-Redi pan. I've looked online at a few different systems http://www.tileredi.com http://www.dixsystems.com/ I'm leaning towards the tile redi. Any experience with these? Thanks!
