I am buying a house that has a half bath downstairs and I need to add a
shower/bath combo or, at the very least, a corner shower unit.

On the otherside of the bathroom wall is a wetbar that sits in the
hallway.

We have been told by the sellers RE agent, that a full bath was an
option when the home was first built, and that underneath the wet bar
is the plumbing necessary to add a bathtub

I called a contractor and he said that it would start at $8k....that
being on slab, he couldn't be sure that the drain was large enough and
might have to get it correct.

So, this project entails, "demo"ing the wetbar, and the wall behind,
installing a shower/tub combo or at least a corner shower, and building
a new wall between the bathtub and the hallway.

I was hoping to spend around $3k
