What on earth has happened here

[Fullrecoveryispossible]

I’m looking at houses and came across this behind the loo. Does anyone know what’s happened here, if if it’s an expensive fix? The rest of the house looks good…

No help but its obviously water damage. It could be a leaky loo or damp coming from outside. I’ll be watching as I have something similar but can’t source the issue.

Weird. You think if it was fixable they’d do it before posting pics. Maybe a surveyor knocked damp out?

Maybe they’re tunnelling out

Curious as to the weird boxed in section behind the toilet …

It looks very wet, you'd have to take a look at the other side of that wall and the rest of the house. Could just be an unfixed leak in the plumbing or some other sort of damp. Leaky plumbing would be cheapest fix. Bigger damp issues obviously more expensive.

That looks like terrible black mould. I wouldn't even view the house 😳

I’m stunned the rest of the house looks ok when the loo is in that sort of disrepair.

Clearly a leak from backof toilet into soil pipe or where the water comes into the loo. Check what's going on outside where the soil pipe if you do view

Could be an older toilet with an overflow thats been leaking. If so, a relatively easy fix.
Looks like the soil pipe has been boxed in.

Other than saying that toilet room needs burning and then safe disposal, it looks like the plaster has blown out. This would be highly suggestive of damp, either from external wall, rising, or some sort of plumbing disaster / mess in the past that is now fixed. Or not.
