Default Bathtub on Concrete Slab

I am installing a tub and shower in a bathroom reno on a concrete slab. The floor has been jackhammered, the existing 2" vented drain located and exposed. The tub is being dropped into a supporting wood frame that will ultimately be tiled. I intend on placing a concrete "second floor" to support the tub. I will install p-trap and stub out such that the tub can be connected to the drain. After the tub is dropped in place do you concrete over the hole that is exposed where the stub out exists, or can I stub out and repair slab before the tub is connected. Thanks
