Bathroom Floor Caving In
My bathroom floor is beyond frightening! It is 39 yrs old with 1" tiles on the floor and 3" tiles 4 feet up the walls. Currently, the concrete is crumbling under the floor tiles and they are coming up on our feet! There are major sunken areas near the sinks, the front of the bath, etc. I know we need to replace the floor, but I'm scared to pull it up and see what is truly wrong. Are we talking replacing the subflooring? Dealing with a really old leak which has gone on forever? Just crumbling concrete b/c of age? I'm concerned a $500 project will turn into a $5000 project. We only have weekends to do this-and 4 kids!. Our bathroom is 19'L x 3'W in the front part and 6'L x 4'W before hitting the tiled shower.

Wild guess without seeing it. You probably don't have the proper thickness in your sub floors ...1/4" would be my guess.
Option 2, you have a major water leakage that's build up over time in certain areas, that would explain diping in certain areas.

But then again, there's more then enough ppl on here that apparently know Way more then me.

King of Cool, you out there?

Without knowing how the house and subfloor system is constructed, the age, what is under this room, where you are located and a few other items, it is impossible to help you. You have to paint us a picture, we can't see it from here.

Give us details, and yes pictures from above and below.

If you have a crappy sub floor + all the added weight of the mud job + tiles and 6 ppl walking on it. That could be your answer.
Whether it's $500 or $5000 safety should be your MAIN concern in this situation. Do not delay it, meaning, don't wait until something horrible happens until you fix it. But like i said, tiles could be be popping up to do a poor mud job and your sub floors BAD wood or not your proper thickness for a tile job.

Update on Crappy Bathroom Floor
Thank you, everyone, for your responses. It turns out it was just the concrete which was crumbling!The floor is fine. The rest of the weekend will be spent putting down new flooring. Whew!
