My wife and I plan on putting up a tub surround.
I have researched a bunch of these and on a few of the reviews I have read that the shelves are flimsy.
The surround she likes (therefore the one we are going with) will probably be this one.
I was wondering could I fill the void in the back of the shelves with great stuff for added strength?
This would firm up the shelves without adding undo weight.
Would the expanding great stuff push to much and possibly crack the shelf void?
