My bathtub squeaks and clunks as I move around in it while taking a shower. I've read that this is bad news and can eventually lead to a broken/leaking tub. I've been able to look a bit under the tub at the drain end by removing a drawer cabinet. It looks like there are rigid foam panels under the tub but they don't appear to quite touch the bottom of the tub; maybe 1/4" shy. I've read that there is supposed to be a mortar bed under tubs. I'm wondering if the original builder/owner took a shortcut or something. I've also read that you can stop tub squeak by installing expanding foam under the tub.
Several questions:
1. Is it true that a tub that makes noise is on the verge of failure/leaking?
2. Has anyone ever heard of using rigid foam as tub support?
3. Is expanding foam a practical solution to a squeaking tub problem?
4. If I was to look for professional help to solve this problem would it be a plumber or a construction company...or both?
Thanks for any assistance.
