I am putting in a Kohler cast iron shower pan tray then tiling the walls and using Laticrete epoxy grout. Wish me luck on the grout :) I didn't want to fuss with trying to tile a floor. I am happy with my decision. Cat-mom has a kohler pan in place and it looks nice. They come in 3x4 and 3x5 sizes. So the larger fits a standard alcove tub site. I will be using the smaller because of size constraints. Cat-moms shower is shown about 1/2 down this thread.

Thank you enduring. I am going to look into those. Do you actually tile over the curb part or just the walls?

The curb is cast iron, but in the 3x4' size the apron may not go down to the floor. Cat_mom has a picture of her Kohler pan and she needed to tile on the outside vertical plane with a cut tile all the way across. The 3x5' pan that I saw at Ferguson's has the curb that goes to the ground on the outside, rather like a regular tub with apron does.

my kohler cast iron shower pan is fantastic! no tiling over curb on mine.

Busybee3, do you have the 5' long Salient or the 4' Kathryn or Purest? If you have the Salient do you have the center drain or the drain at the end? I am thinking of changing my plan to work with a 5' long pan instead of the 4' since I just made the room:)
