Why has my bathroom floor dropped

[Misha007]

Just needing some help with regards to my bathroom floor on the second level. My bathroom floor has dropped about 1/2 inch from the skirting boards on one side and on the other side there are signs of it starting to happen with cracking along the skirting boards. It seems it is only the bathroom floor that is dropping. I have had a couple of builders over but no one seems to know what is going on. Can anyone help please.

Could be chipboard under the floor and its been water damaged. Seen it happen on a few jobs.

Thank you for reply re boards, does that mean I have to rip up the bathroom floor tiles and cement to see what is going on ?

Are you in the UK or Australia? Which floor is the bathroom on?
