Put differently, say there's an infinite volume of water that has some rocks in it, is the volume of water truly infinite? Though there's a place where there's no water?

Certainly you can have infinite regions with boundaries - an infinite volume minus a finite volume is still infinite. I presume, since you're posting this in cosmology, that you're thinking of space or spacetime. This doesn't have any holes in it anyway, so far as we are aware.

Infinity is a mathematical concept. If you can put rocks in it, you speak about something which exists within the universe, and then - in case it should be infinite - all rocks are already in it.
