OK experts take a look at my mistake fix. Just as a reminder this is where I started. Professional plumber paid to do the install. He put it exactly where I asked and it was totally wrong when the tub was delivered.
After a bunch of head scratching and input from this site (thanks!) here is the final dry fit. With what I have done do you see anything that wouldn't work? (Yes I know I've got a piece of PVC in the middle of everything. It will be replaced with ABS when its glued up. And according to a licensed plumber local code allows for PVC to ABS transitions IF you use green transition glue.) This first shot is looking down the tub's over flow.
This is a different angle. It worked out the the 2x4 brace for the downstairs fan and the cold water supply line were both in the way. I rerouted the copper and reinforced and cut the fan brace.
This last shot is a close up of the drain and P trap. So does it look OK or is there a problem?
