I have a cracked shower basin. It looks like it was caused by the drain being off center. So it is cracked on the high side about an inch away from the drain. Is there something that I can do to fix the crack or do I need to by a new basin. It has already started to leak.

What material is the base made of?
Fiberglass, acrylic or plastic? Let me know, Tom

It is acrylic.
