Hey Mark,

I went out and picked up a bunch of fittings today. I had everything in front of me and started dry-fitting the setup. I had a physical layout idea that will work perfectly for me if it is an acceptable plumbing layout. Would you mind taking a look at it and critiquing?

That won't fly Rob... the wye for the sink/shower drain MUST roll above the centerline of the toilet drain. It is a very specific requirement and it is why I mentioned it in post #5 and #15 and typed it out in pictures on post #12 and #19. Mygirlsdad77 even stated it in his first post (post #14), so you got to figure this is a pretty important rule... ;)

See what else you can come up with... I'm in and out all day!

When you say "roll above centerline" does that mean that the 45 degree portion of the wye needs to be perpendicular to the pipe that it is joining to (stick up like a tail fin), or can it be at less of an angle, say 45 degrees to the horizontal?

You can roll it up like a fin or just roll the wye with a street 45 in it so that the wye/45 is above the centerline... can be a bit tricky to get the wye above the centerline and still get the pipe straight so play with the wye/45 and you'll see what I mean.

Below is an image of the wye rolled up and straightened using a 45 degree fitting... See image below.
