Shower Tub

A fiberglass shower / tub insert earth to solve?
I have one piece fiberglass shower / tub insert quarter bathing. A place on the floor of the tank is back and began to pick up a puddle of water after each use. That's about 1 cm in diameter and leave some soap film or after such use. Can it be fixed or I am forced to change the insertion in its entirety?
It can be repaired, call a company bathroom repair.
