Crumbling Concrete under removed tile in Basement Bath

While removing ceramic tile floor from our basement bath, that was attached directly to the concrete floor, I found a small patch of concrete between the toilet and the tub that is crumbling and sounds hollow. I'm guessing when putting the bathroom in many years ago they removed some concrete to put in the toilet drain, and replaced it poorly???? I have no experience with concrete. Anyone have any ideas on what caused this? Any solutions? Do I need to tear out all of the crumbling concrete? Thanks in advance for your help!

Concrete is super strong, but can't last forever. I would fix the bad parts.

Do you live in florida by any chance?

Repair the concrete and tile as usual.

No, I'm from Wisconsin.

If part of the crumbling concrete is on the edge of the tub, does this mean I have to remove the tub to repair the concrete under the tub? All I want to do is replace tile.

Thanks

I don't think we can recommend without seeing a photo, in your particular case.

Many times a little project becomes a huge one very fast. That's what happens in older homes, so be prepared for the unexpected.
