HELLO HELLO I JUST WAS WONDERING WHEN YOU ARE INSTALLING A CORNER TUB OR ANY TUB MADE OF FIBERGLASS ARE YOU TO DRILL SCREWS INTO IT ALONG THE EDGE INTO THE WALL.CAUSE I WOULD FIGURE THAT COULD CAUSE CRACKING ?
Predrilling holes would prevent cracking. But you could also just use large-headed galv. roofing nails and drive them just at the top of the flange. The head holds the flange in place.
If you use the roofing nails, you don't nail through the tub, but just use the head of the thing to hold it in place. You should also put ledger boards under the edges to give the rim support. I'm pretty sure thatthe instructions cal lfor that, too.
