Thanks Old Timer! The slab is rough there around the penetration, but it will be stained concrete floors.
Good news is we passed the inspection! He said we could have run water lines in the wall and insulated, also maybe needed an offset toilet flange, and 2" VTR here because of the cold winters, so have to put a coupling before the 1.5" vent passes through the roof. We have to fill the shower pan with water for the final with a test ball.
