Experts, how is this rough plumbing plan?

But I caught a miss-speak in your answer "You can use a wye plus a street 45 (with parallel inlets, not in the "combo" configuration) if you get the 2" lav/shower drain parallel" -- This would need to be a Street 60 if I roll up the 3x2x3 wye per MA code

No. If the wye barrel is horizontal (rather at 2% slope, which is negligible), and if you roll the wye up 45 degrees from the branch inlet also being horizontal, then a 60 degree elbow is what you need to bring the branch vertical, not horizontal.

Regardless of how much or how little you roll the wye, a 45 degree bend will let you get the branch horizontal, parallel to the barrel of the wye.

Cheers, Wayne

I still got much learning to do. After you pointed it out, visualization makes so much sense.

Fixed! Thanks so much for the guidance!
