An illustration to help you consider the room. It is not a record of work completed in your area.
What the symptom does and does not tell you
A cracked fiberglass shower raises two separate questions: what caused the damage and what bathing arrangement you want if replacement is warranted. Record where the crack is and any visible movement or moisture without treating those observations as a diagnosis. Replacement planning should consider support beneath the new unit, not just a different surface.
Does a crack prove that the whole shower must be replaced?
No. Its cause and extent need assessment. This page concerns substantial replacement planning; a repair-only request belongs with an appropriate repair professional rather than being presented as an accepted remodeling project.
Turn findings into a replacement decision
Ask the assessing professional to distinguish the observed condition from a suspected cause, and to explain what further access is needed. If replacement is warranted, describe what you want to improve about the bathing area instead of selecting an identical unit by default. This planning route concerns substantial renovation; it does not establish acceptance of a repair-only or customer-service request.
This is planning guidance for a homeowner who makes the project decisions. Service fit and current availability need separate confirmation before any work can be arranged.
