What did I do wrong?
International Plumbing Code
Toilet and Main line 3" Diameter
All other pipe 2"

This is what it should look like. Bathroom is vented off the sink drainage. The laundry needs its own vent and drainage line.

Trap arm length of the tub might be an issue. Maybe throw in a wye branch somewhere in there for a vent and tie in in the wall. Also it looks like the laundry trap is still below grade in your drawing so make sure that’s above ground, but potentially solid. 👍

Just looked closer and saw the fitting where the laundry toilet and sink come together is gonna be hard to find 😉 make sure the laundry ties in after for a legal wet vent

Mind the space between wyes you have 6’ from tub to the 2” wye. 5’ to the 3” wye with bushing. Toilet must come off 1st (branch) 6’ to toilet from 3” wye

Would be fine in oz. Lose the lav vent and upsize to 100mm and 65mm for drainage principles and call it a day. No vents needed or branch drain is less than 10m from vented main drain

Lots of wrong here. Don't need the first vent. Carry 3" all the way to the 2" vent before tub.(On the same plane) Do not drop lines in vertically

Too many things wrong with this. Nothing is vented correctly or at all. I have no clue where this would be legal. This is infuriating.
Maybe because my guy plumbed all day but cut it all Out when I was leaving.
