Help! Bathtub Mud Bed


In attempts to install our first bathtub, we were told that we could use mud instead of cement (or mortar as we should have probably gone with), however we used bucket mud instead of a dry mix and close to a month later, the mud still isn't dry.

Will it dry? Is it a problem? Is it likely to mold?

My son has mold allergies and respiratory issues and this is the kid's bathroom, so I am very concerned. We obviously don't want to rip out the tub, pipes that the plumber soldered...twice, and drywall (luckily, we haven't tiled yet), but if that is what we need to do, I guess we will have to. I just wanted to see if that is the case. Thoughts?

You'll have several other issues caused from using the wrong material.
Biggest one is the tub is now unsupported and may crack.
Even if at some point it does hardens up by now someone has likely stood in that tub and compressed the mud leaving a gap.

Question, do the tub feet sit flat on the floor without the mud? I have a shower base with the same instructions, and IMO, they are stupid. After much reading it boiled down to eliminating squeaks. The feet on my base, when placed on a level floor, provide full support.

I agree with the need for support if the feet do not provide it, as my old shower stall gave way after 20 years due to lack of proper support. But to eliminate squeaks, the final solution was/is a $10 shipping blanket. That is essentially what the mfg suggested as an alternative, but the stores didn't even bother to carry it.

Back in the day before they made fiberglass tubs that have the ply wood support all the way across the bottom. it was pretty common to use drywall mud instead of cement because it was cheaper and easier to mix. but they would use quickset 90 or similar product not the stuff out of the bucket also known as premixed or skim coat.. i think? i am not a drywaller. Any way this is the classic "just use mud dilemma." There is a post at the top of this section dedicated to this situation.

proplem i see 1st ..you were told wrong..joint compound is not stable for the base of a tub or shower.....2nd after the mud is out of the bucket the top will crust over locking in moisture and being so thick it may take a very long time to dry, and even if it does its not going to be hard enough to be supportive of the purpose its needed for...so if the tub was not level to the floor you can expect it to fail down the road....only real solution to this is to remove tub and install it properly..sorry ... I doubt you will have a mold issue...aleast not enough to be worried about..
