I can’t identify these drain rough-ins

[Scott_AM]

I’m doing a lot of planning towards finishing my basement. Home was built in 2018 and they left these stubs for a future bathroom. I can tell the back one is for a shower, but I’m stumped after that. I deliberately shot this pic at an angle to show the ejector pit and sump pump. What’s what here?

Thanks for the guess. I was thinking the same, but where would I drain the vanity sink?

Into the vent above the floor

I get it now! I don’t have a plumbing brain and didn’t consider the dual purpose of the far right pipe. I guess that would be hidden in a wall and the toilet would sit perpendicular to that wall.

This is what I'm imagining now. Not scale of course, but is this the general idea?

Slide the shower against the wall to the right and get a center drain shower. Yes.

Thank you so much for your help! This makes sense now! I appreciate it!
