Oh I hate to tell you this. We have rental homes and have had to do this awful repair several times. You will need to tear it all out. Let it dry. Install green Backer board and then apply tile . Sooooooo sorry.

Tile walls normally don't cave in just because of bathroom moisture (like steam or whatever). You may have a leaky pipe or other fixture inside the wall where it caved in.

In any case, you're going to have to tear it all out and start again. At that time, you can look for the source of the water and fix it if it's a leak. Replace all water damaged or moldy wood. Then do the wonder board thing and re-install the tile.

And, you might as well buy new tile while you're at it. Otherwise it won't look right if you try to recycle the old tile (it will have old mastic and grout on it).

I just finished this repair in my house. 15sq ft repair.
All the answers are spot on, you have 2 choices; complete tear out or patch. In either case the steps are the same.

1. tear out damage.
2. find source of water intrusion and fix. In my case it was dried out and cracked grout which allowed the board to get soaked.
3. treat any mold growth with tsp, then 3:1 bleach mixture and scrub. let dry completely.
4. Install vapor barrier, I don't think I saw this step elsewhere but it's very important to prohibiting damage. With a patch you may be able to get away without it if there isn't one existing. With a complete tearout and rebuild the barrier is an ABSOLUTE.
5. Install Cement fiber board and tape.
6. install tile, there are some great online DIY videos for installing bathroom wall tile, just search Yahoo for them.
7. float in grout and caulk.
8.Let cure at least 72 hours but preferably a week.
9. take pictures and enjoy the work and cost savings.
10. Use your shower again.

Thirsty Mind is correct on this. You do have to tear it all out and start from scratch. Whoever did your drywall in the first place did not do it correctly. You need to have a real good look at what has been going on behind your tile work. You could possibly have major damage to your studding and you need to do the Ice pick test on all the wood in the effected area. Then check the flooring where the water has been leaking. If it has not been leaking for to long you might luck out and be able to just board it over with the Green board. But check carefully, If it gets moldy back there and in the flooring area it can be dangerous and expensive. So take your time and do it right. It will save you money in the long run!!

She is right, you have to tear it all out, let it dry. I wouldnt put green board back up though. If you dont want this problem to happen again, put up 3/8 wonder board instead. Its a concrete/cement board made for high moisture and wet enviorments like yours. Its sold at most Home Depots and Lowes in 3' x 5' sheets, you just glue and screw it to the wall, patch the seams if you are worried and apply your tile directly to it.

If you wanted to get away cheap, and sacrafice the look, you could go with the 4 x 8 sheets of tile look a like too..... probably cost you quite a bit less, but it also looks it !

Since the drywall got wet, and may still be, removing the tile should be easy.

Without removing the entire wall, you should at least feel inside to determine how far the WET extends. AND TOO try to determine the WHY of the issue.

Since it's a patch; I suggest still go with concrete backer board of the same thickness as the old dry wall. Best case would be to remove tile and drywall to two opposing studs, add the backer board patch, remkove whatever mortar is on the back of the tiles removed, re-mortar, grout, and go.

Added thought with all due respect tear it ALL out may not be neccesary, and PLEASE do not bother wasting time, energy, and funds on Green Board in a shower/bath area...

You have to do it over this time use cement board for the backing.
