My fiberglass bathtub/shower floor is cracked and leaking onto subfloor and into basement.Crack is
approx. 18″ long.When unit was installed 22 yrs. ago,seems like there was’nt a good base built up between
floor of tub and sublooring.Floor of tub has “soft spots”.Is there any way of repairing this,without tearing
the whole tub/shower assy. apart, because unit was installed while house was being built and the only way “I”
can determine to remove unit to make repairs to bottom of tub floor, is in pieces because plaster walls where
put in after bathtub/shower unit installed. Thank you
