I am going to change tub/shower to walk in shower with either sliding doors or glass hinged doors. I'm not sure of the pro's and con's of either of these. The cleaning and mold problems or the cost of glass doors. The opening is 60 inches across and 72 inches high. I would like to use a tile-redi pan, but nobody seems to know much about this product as to attaching either one of these doors. Any feedback would be much appreciated.
