I've recently made some big improvements to my bathroom, including getting support under a once saggy floorboard, and also new floor covering, and other improvements. One fairly "small" but extremely annoying problem I have put up with since purchasing my shack in 1996, is a pipe, or a rod on a shelf in the shower. I have a fiberglass combination shower stall and bath tub, and this rod, or pipe, which is probably for a wash rag, has never been firmly in place, and keeps coming loose. There is some defect in the mounting rings that keeps them from holding this rod firmly in place. I have some photos which I will be posting later to show more specifically just what the problem is.
