New steel tub creaking?
I have installed this tub: http://www.americanstandard-us.com/bathtubs/new-so...
as per the instructions. I have installed tubs before. Instructions do not call for mortar bed, so I did not use one.
The problem is, if you stand in the tub and shift your weight from side to side, the tub makes very loud cracking/creaking noises from beneath, coming from the [glue??] connection between the styrofoam pad and the steel tub itself. Whenever you rock your weight to one side, this connection makes a loud "snapping" or "cracking" noise as it shifts with you.
I have tried shimming under the styrofoam, I have tried shimming between the styrofoam pad and the tub, I've tried shimming under the skirt, and also under the nailing flange between the flange and the stringer. I've put shims everywhere I can think of -- the noise persists.
What is causing this noise, and how do I make it go away??
Response to below:
No, I am 100% sure the noise is coming from the connection between the tub and the styrofoam. I could not figure out how to get the sound to go away, so I cut the sheetrock open on the other side of the wall so I could look in underneath the tub. The styrofoam isn't rubbing against the floor, and the noise is less of a "creak" and more of a "crack", like a snapping sound whenever you lift your weight up and shift it to somewhere else.
Taking the styrofoam out and using a mortar bed would be impossible, the pad is about 5 inches thick, meaning the bottom of the tub basin sits 5 inches off the subfloor and between the basin and the floor is a thick piece of styrofoam.
I will try filling up the tub with water and letting it sit overnight tonight, but I do not have hope for this method...I could be wrong though.

Can you fill it with water overnight so the weight settles it in better? I always fill it with water after it is installed and then caulk it in so it squeezes the caulk when empty. There is no way to shift it once all the walls are finished, so it may be just slightly springy now.

the noise is probably the styrofoam rubbing on the subfloor
can't say I am familiar with this tub but since it seems you can still get to the underbelly I would pull the styrofoam and pack mortar under it
