To simplify this as much as possible, an unfinished basement is a basement that is lacking the elements that would typically be seen in a finished room. These would include items like flooring, ceilings, insulation, and finished walls. Typical unfinished basements are as such quite bare, usually with the cement of the foundation making up the walls and the flooring, with the inner workings of the ceilings exposed.
