Let me get this off my chest:

Silicon is not an adhesive, it's a caulk. It will not hold anything to the wall.

They use clear silicone to hold fish tank seams together.

Was. It's gone now. They used clear silicone to attach it to the wall - and it didn't hold.

They use clear silicone to hold fish tank seams together.

There's one in every crowd.

Seriously, glass to glass I can see; fiberglass/plastic to wallboard, nope, not going to hold. The fiberglass/plastic will let go.

What's funny, is the fiberglass is smooth, and clean. Not a spot of silicone on it - all on the wall.

Gotta love DIYers:D I'm occasionally guilty of using whatever is on hand to fix a problem. My favorite fix is to use white toothpaste in place of spackle to fix small holes in drywall:D

Yea, if it was a DIY, I wouldn't be so upset..

But this jackass (previous owner) was a contractor, and did stupid things. Like cemented in the whirlpool tub, and the drain line, so I have to literally jack hammer the tub out, plus cut the drain line and then jack hammer the concrete out around it.

I had a similar one here. Our house was built new in 1997 and we moved into it in November '97. About 2 years later, the downstairs bathroom ceiling starts getting wet spots on it. Well, when I noticed it, we had a heckuva storm going on outside, and it looked like water had been pushed back up in through the vent fan duct...WRONG!!! A week later, the ceiling falls down. Turns out the lovely plumbing sub that did the upstairs bathroom used vinyl caulk around the faucet handles instead of silicone caulk. Needless to say, it fell apart from being immersed in water...and I now have silicone caulk on ALL fixtures in the house.

Jeff, not to get off of the topic, but I came across this link: http://www.draper.co.uk/ Is this a distant relative of yours?

Not to my knowledge, but it's possible. I am about 20% English in heritage, but Draper is a very common English name.

Actually believe it or not as silly as it sounds due to the size and weight of a whirlpool tub with water that's what your supposed to do.

I have the same tub, and I did not set in in cement. It sits on wood beams so it can't go anywhere. Cement is not necessary.

yup, I found the installation instructions on American Standard's website, and it makes no mention of cementing that bastard in like that.

The new ones have adjusters and are designed to be just put into place.

Also, as I research what this jackass did, and how to fix, I realized I posted mis-information.

There is caulk, and adhesive. caulk is supposed to stay soft, and supple. No real structural strength - ie, it will pull apart/tear when any real force is applied. Main purpose of caulking is to SEAL.

Adhesive, however, is different. Most adhesives dry to a hard surface. They are designed to hold things together - therefore, they can resist tear/shear forces. They are NOT usually designed to seal. Main purpose of an adhesive is to HOLD, not SEAL.

Now, there is silicone based caulk, and silicone based adhesive.

There IS a difference. Silicone based adhesives don't get 100% hard - but they are usually harder than a caulk, and they don't hold as a well as a non-silicone based adhesive. The idiot in my case, used silicone based caulk, not silicone based adhesive, although that is still wrong in my mind for what it was supposed to do.

Still, the point of my rant is - use the right product for the job. Makes a huge difference during the lifetime of use. There is no mechanical reason after only 7 years of use that this bathroom needed to be gutted (besides the horrendous style choices), if it had been put together properly in the first place.
