During a bathroom remodel, our plumber installed an alcove fiberglass tub in our second floor bathroom. The tub creaks and pops when standing in it. I asked our general contractor about it and what support was under it. She said that the tub is installed per the manufacturer's instructions and that because it has feet needs no other support. I don't believe the tub should creak and pop like that. A lot of things I find online show some sort of support for a tub - whether it be mortar, foam, or a pad that comes with the tub (our tub doesn't have any of these). Our project is currently on hold while we discuss the way forward with the tub. Any advice on what I should do? I am pushing the general contractor to remove it and add support.

If actually installed as per 'specs' you need a better grade of tub OR a 'better' floor under it.
If not installed as per 'specs' you need a better GC and / or a better plumber.
Either way you have two choices:
Remove, inspect, and replace as necessary to remove 'flex'.
OR
Fill the 'void' under the tub with low expansion spray foam and hope for the best.

I agree with Bern except I would use max fill or big gap spray foam and fill the tub with water to the overflow plate to prevent the tub from shifting as the foam cures

you have no choice. open the wall on the shower end and possibly the long wall as well. spray foam under the bottom.
your contractor is lying to you.
your plumbers are incompetent.

Thanks.
A better tub is being delivered to be swapped out for the one that was installed. The CG said that support will be also installed.
We will closely monitor this installation.

YOU need to verify that the manufacturer's installation procedure is followed.
In order to do so YOU need to read the instruction 'sheet'.
