No one can really help you without taking a closer look. Sharing the package or link to the object would sure be helpful.

There is a batch fix in the latest version of Sims 4 Studio for this. I'm not sure if it resolves disappearing bathtubs, but it's called "Fix CC Bathtubs." I'd recommend giving that a try. If it doesn't work, then someone would be happy to take a look at the file and see what's wrong.
