Basement - Rehab with existing rough in

[DIYMan]

Good afternoon everyone,
Moved into a new build last year and will be tackling the basement myself over the next several months. This includes a 3 piece bathroom that we had roughed in during construction. I just wanted to make sure I'm interpreting the layout correctly so I'm looking for some guidance on what I'm looking at. Moving from left to right, then front to back -

- left pipe is 2" drain encased in a 4" cut out, is this the shower drain?
- right pipe is a 3" drain, toilet drain?
- set of pipes (tied together), is that for the sink? I followed it back and it's tied to the vent pipe for the discharge pump as well.

Thanks for any insight.

I think your assesment is correct . I dont know the exact floor plan , maybe the builder had a floor plan in mind, I would have expected the 2 pipes tied together to be in alighnment
