How old is the bathroom?
Is this the first time there has been water evident?
is there any indication of mold around the caulking or grout lines? ie black forming in the grout lines or behind caulking?
any signs of water damage on floor/walls?
Start there - if yes then you may be looking at opening up the walls to investigate the issue.
Any small cracks in the grout will allow water to seep into the substrate
