I bought this bathtub and it looks good. However, a few months later, a small crack began at the bottom of the bathtub. Recently this crack began to rise and has now reached its entire length to the top. Now, the water is leaking. Obviously, the bathtub didn't move and I don't understand how this could have happened, perhaps there was a manufacturing defect. The website says that the bathtub has a lifetime warranty, but when I reached out they said that this doesn't apply to the tub. :( It's an expensive item to throw away and rebuy it!...
