Usually a concrete lined shower would have a pan or vinyl/neoprene/pliable
plastic/waterproof membrane under the concrete.
This is the "dam" so to speak, and here we need to fill that with water to
get it inspected by the county building inspector.
So, the concrete is a base for the tile, and the membrane under the concrete
stops the moisture that wicks through.
It is tied into the shower drain.
I suppose one could put the membrane in, float concrete toward the drain,
and when dry, paint the surface or seal it well with
a waterproof sealer/silicon/product.
If trying to go cheap, and person could put in exposed aggregate floor also.
Remember that shower floors do get very dirty, and the smoother/or less
porous they are/less joints/means easier cleaning too.
I know that there are boat paints, that will go over concrete like a
concrete boat that are very smooth and washable.
Lots of ideas.........

hehe I like that subject line..
But.. do you have to tile the shower floor and sides ? I am partitioning
some two bed apts and making them into 4 rooms with bathroom (shower only,
no tub)is it possible to make one out of cement and have the good moisture
control? Pools are like that and some wash tubs/basins.
Looking for the cheapest way to do these renovations.
