Plumber in the house?

I'm trying to figure out how the drains work in my bsmt bathroom rough-in.

The location is all wrong so I'll have to break the floor and change the location of everything.

In the pic you can see the drain for the vanity, toilet and shower under the table then a vent and 4" stack.

The 2nd picture is showing the drain location to scale.

Any help before I get the sledgehammer out?

p.s. the main building drain runs down from the existing floor drain in line with the double doors.

What changes are you trying to make? The small 1 1/2" line you say is a vent, how do you know that is a vent? If it were piped properly without having the floor cut up, it looks like the bathroom is wet vented through the bathroom sink drain. But the problem is I do not know the code your town/city/state uses compared to my state.

Basically relocate all the drains to accomodate the design below.

Here is what I would do using IPC code and assuming the 4" drain is the outlet of the house. You will be eliminating all the old existing plumbing under the floor. This will work the easiest believe it or not.

The first thing to do is cut open the piping around the 4" drain and verify the direction of flow, depth of pipe, and if there are any other bathrooms connected in the same vicinity.

After that information is known, we can continue.

I know the existing main drain for the house runs down from the exisiting drain on the right under the double doors then past a clean out to the street.
