I used the 1 in flex line from Home Depot you can see under the sink. It is run around and under the shower pan. When you look under the seat into the area open under the shower pan you can see all the way to the front wall. open the bathroom access door and grab it and snake it through a 1 inch hole drilled from the cabinet side. I can send more pics if anyone is going to do this. Also the caulking comes off with a rub of low Oder mineral spirits and a plastic razor blade from an auto parts store or west marine.

I think I see how you handled the supply lines, but how did you deal with the drain?
