AIBU to doubt the council over damp from the bathroom floor?

[TheOpalFox]

Apparently the council said this is caused by getting the bathroom floor wet? It don’t get soaked yet look how bad this is in my living room? Or could they be right. ?

Yes your living room ceiling has got water stains - so something has leaked through and caused that to happen . Maybe use a bigger bath mat on your floor to absorb the spills ?

What flooring have you got up there, does the bathroom floor get wet a lot, could water be seeping under the flooring and then soaking down rather than drying out?

Have you had the bath panel off to see if the plumbing under the bath is leaking?

In my old council house, once the bath was full, it pulled away from the tiles a bit as it had been tiled incorrectly/not properly sealed, so whilst it didn't look like there was a lot of water on the floor, all the water splashing down the walls from the showerhead was going under the bath and into the ceiling below. Also the waste pipe from the bath was leaking a bit which didn't help.

I'd take the panel off, have a look, if its not obvious, fill the bath up with a few inches of water, see if there are any obvious leaks. If its not that then spray some water around the edge of the bath where the sealant meets the bath and check again, i recommend a good torch and some tissue paper to see if things are coming away wet that aren't easy to see. Unfortunately I only really found the extent of the issue when we had the bath ripped out and all the plaster around the edge of the bath and below was blown. I had fixed it by resealing the bath when I noticed it was lifting but it had obviously been going on for years and as the plaster got worse, the floor got more of the water.
