Forum Title: is this acceptable in terms of vent/connection
Is this acceptable, specifically the venting situation? I am unsure if a vent has to be after the shower (or after the toilet) based on how close everything is to the stack, which is 4 inch CIP or if it's being stack vented, basically, or really, it's wet venting because each section gets bigger. The connection from the toilet to the stack can be 4 inch instead of 3 too. This is all under a slab, so I'm trying to plan out what is possible before doing layout of the room.

they come in left or right, the 3'' is a simple, toilet drain, the 2'' catches the shower/tub if you ue the correct left or right, for your situation, the outlet points straight at the tub this is the easiest/ cheapest way. if you want to do it different fine,,,,,we can dio that also

I have a different idea, that will be a lot easier. useing a 3x3x3 san tee with a 2'' side outlet. and wet vent the lav install the tee under floor centered on the toilet, in wall, arm over to lav and arm to tub

So a Tee like that would have the outlet going the wrong direction, unless you're saying use the outlet as a vent to the exterior wall and build a new vent there. I think I was imagining a simple sanitary tee under the toilet. I will probably post a more detailed question with a larger diagram - the current issue I'm trying to figure out is if the sewer line is deep enough for these things to tap into at all and still have sufficient drop. My drawing's pretty unclear there - that intersection at the bottom of the main stack where it says to sewer, it's actually coming straight at you from the perspective of the drawing, with the street behind you, just under the slab.
