I have a Fiberglass shower stall in my bathroom, and on the base of where

Is the crack right through the floor and leaking? It might be a surface

that is not critical.

How can I repair
this small but needed repair without tearing out the entire stall and
replacing it with a new one.

If the crack has severed the reinforcing, you will have to remove it to
repair.
That kind of fracture will require reinforcing on the backside to repair.
If the
crack is just in the resin/gelcoat and the glass fibers are intact, you
can sand out
the surface until you get to the fibers and then fill the sanded area til
it's back to the
same thinkness as the adjacent material. What you fill it with will
depend in part on
what it's made of - acrylic, polyester, vinylester etc. I've never dealt
with glass reinforced
acylic so you'll have to use google. For gelcoat, you can repair it as
you would a boat:

If appearance is not a major concern. A basic fiberglass patch kit should
do the trick. These usually come with a can of resin and one of hardner
plus an assortment of fiberglass fabric patches (matts). Get these at most
hardware stores.

The resulting repair looks like a "bubble gum" or "big bandaid" patch but
it will hold the water in.

With a bit of careful sanding before and after applying the patch, and some
matching color Gel coat, you can blend it in reasonably well. It will be
difficult to make an invisible repair though.
