This is the second tub I received with a crack(s) in the acrylic. The first one I received had cracks and a chip all over the back lip of the tub. I got a replacement, however, the replacement tub has a hairline crack in the apron of the tub.  I will never buy a Signature Hardware tub ever again! I have read somewhere that the more the acrylic is stretched the more likely it is to crack. This material must be thin and not manufactured well. I will be going with a different brand next time.
