concrete shower pan removal

My wife would like to move our freezer in our basement
to where now sits an old shower pan made of concrete
or cement. This pan is about 8" thick and has a 1" pvc
pipe coming from under it running on top of the floor
to our floor drain. These facts makes me believe that
it was poured separately from the floor and thus could
be removed simply with a jack-hammer, skimming across
the floor and between the cinder block walls. My wife
is afraid that this process might cause damage to the
cinder block walls or the floor. Is this the right way to do the
job or is there a better way or are we stuck with this
concrete shower pan?

In the probability that it was placed afterward, there will be a cold joint, and even though there will be a material adhesion, when you began to remove, you will see the cold joint began to separate, not necessarily in-mass.
Using an electric jackhammer or a HILTI demo tool, start at the area farthest from the wall, pushing the material away from the tool. If you find that there is some material remaining near the cinder block wall, a roto-hammer with a chisel attachment is a gentler tool and offers more control., as does a 3lb hammer and a masonry chisel.
