Yes Hard work

Good job buddy! That’s not easy work. I’m a licensed plumber. One thing you need to account for is the venting for each drain. It doesn’t look like you’ve planned for your tub or toilet vent. Sink vents are easy since you can use a mechanical vent. Venting is important. Post a follow up of the underground before you cover it up. Can’t wait to see

I used wet vents for tub and toilet. And adding air admittance to sink. Have oversized drains 4" and 2".
