Wall cracking above the bathtub surround

Had a Maxx bathtub surround installed Dec 2009 by a contractor.The wall that was built around the surround started to crack within hours.They fixed the wall 3 times and before long it cracked again for the 4th time.It is now cracked around the whole surround about 1/4 of an inch from the top of the surround.It looks like it may be cracked where the flange meets the wall.Any ideas what may cause this and how it can be fixed.

Different materials expand/contract at different rates. I suspect the wrong materials were used for the joint. For this type of joint, you need something that is waterproof but remains flexible enough to move. It could be something as simple as caulking with a siliconized latex. Not silicone, however.

The instructions say that the bathtub must never be supported by the wood stud underneath the tiling flange only, but by the wood stud and the floor, use wood shingles if necessary. The flange is not designed to carry the weight of the bathtub. Install 1"x3" piece of wood all around the alcove. If this step wasn't done could that also cause wall crack or other damage? Somehow I don't think this was done.

I would say it is a direct reason for the cracking. As water is added, plus personnel weight, if the tub were not supported in accordance with the manufacturer's suggestion, then it will sink. The walls won't move, therefore the cracking. Sounds as if it needs further support before you throw money at repairing the walls.

I agree with chandler. If the unit is not properly supported from below and is moving when you shower, no caulk will be flexible enough to survive that movement.
