fiberglass shower / tub enclosure

[Greg C]

i have 2 bathrooms with fiberglass tub and shower s they are old but but still look ok i want to keep them and just put new doors on them and get this place rented
the ploblem is when you stand in them they seem to flex and make a slight squeek noise seems kinda flimsey is there and way to bulk them up i was thinking of getting to the underside
through the out side acess doors and spraying that foam or something under there to give it some more support ,,, any ideas ? :lol:
