We just bought a house with a fiberglass tub. There is a leak and yes at the drain. The tub has movement...you can feel it. So, after opening first floor ceiling the problem is right there...the tub is not bedded and will start leaking again. In fact I found out from the plumber he'd did the same repiar....tightneing nut and plumbers putty three time in the last two years. The question is it seems like it's easier to change out to a cast iron tub rather than trying to set this one into mortar mix. The house is in CA so in addition to normal movement of settling we get the occassional earthquake some which aren't strong but still shake and twist.
Suggestions!
Thanks
