We have a 30 year old fiberglass tub/shower combo and a fiberglass shower stall in our home. The tub has had a crack in it and now has a smaller crack next to it. We have been told that We must have dropped something in it by one person and someone else told us that fiberglass tubs just do that.

What is the life span of a fiberglass tub?? Can it be repaired or is it wiser to replace it, altogether?

The shower stall has a leak somewhere. It is in the master bathroom and the water has now damaged the wall between the bathroom and bedroom. The floor of the stall feels spongey around the drain. Could this be the source of the leak??

Are these fixable?

HELP!!

Thank you.
