I learned my lesson about particle board in kitchens and baths about 30
years ago.

You can rip it out and do it right or learn what I learned the same hard way
I did.

The choice is completely yours.

the bathroom already has particle board...

Not saying particle board is correct solution. But I will say, that for
several decades after mud-bed died out, and before backer board became
common, particle board underlayment sealed with I-don't-remember,
covered with grouted tiles held down by mastic, was quite common. Same
for under kitchen vinyl floors, but the PB wasn't sealed, since it
wasn't considered a 'wet' usage. Even in modern times, I've only seen
backer board in a kitchen if they were planning to put down
heavy-but-porous clay tile.
