Hi. I have two questions pertaining to a shower remodel. One, I will have 4 or 5 shower heads producing a total 10-12.5 GPM. If everything is pitched and vented properly will a 2 inch drain be sufficient to get rid of the water?
Yes, it will be fine , assuming the pipe is clear of any blockages
Second, does anyone have a suggestion as to how far apart body sprays can be to be effective? I'm thinking of putting in a 60x32" shower pan and putting the sprays on the 60" opposing walls. Thanks
The sprays can be as far apart as you need them . Depending on how big you are. LoL

Its a personal preference. If you stand in the shower stall, how much of the water sprays do you want hitting you?. Those body sprays should be adjustable {up, down, left and right}, like a regular shower head.
I also recommend to create a continueous loop from the first spray to all other sprays, and end back to the first head. That will ensure equal amount of pressure and flow from each body spray
