My Tub Issue Rides again!

Maybe it can be shimmed up with some thin wood between the tub bottom corrugations and the subfloor plywood?

..a jack?

We just went thru this last year. You have to build up the sub floor to support the entire bottom tub, we also replaced the tub portion because it was cracking alot. Much more solid now and usable, no leaks.

I used Luan plywood to raise the tub.
See my previous post

Ok, I'll just tell you what I would do and it's not the "exact perfect way" but I think it would really work.

I'd go buy several rubber shims or PVC shims. I'd stick SEVERAL under it in multiple places. Get a solid foundation of support.

Then I would buy the expanding foam "great stuff" and spray it in all the nooks and crannies (avoiding drains and cracks). The foam expands well and is fairly solid. It may back up the shims for support especially with the expansion. Think of it like a solid platform of hard foam with many heavy supports through it (shims).

Anyway, that's what I would do. Unless you can find a very solid thick piece of rubber and cram it there underneath.

Anyway, THINK SUPPORT.

STRABO--did yours have a glass enclosure? Ours does. I would dearly love to pull the whole shebang our and replace the tub/shower walls but I don't think I will be able to convince my Hub to do this. Is it a real big ugly job? I want it to be sturdy enough for him to use and he is about 100 lbs more than me.
