welcome. could have been better circumstances...
if it is a fiberglass tub, they can be repaired in place. lowes or home depot should be able to give u the name of someone in ur area that can do it.
may want to check the price of repair verses replace. you do want to check out the supports too. i've read that a couple others have had a similar problem due to poor support.
with that said, u may want to talk to ur dealer. they may want to make it good.
