leaking overflow drain in tub

[JohnHanna]

Hello All,
There is a leak from the tub which I believe is from the overflow pipe which isn't fit correctly. I've attached some pictures. The problem is there is no way to access this bathtub as it is fully tiled and boxed-in. Is there a way to fix this without removing tiles? It feels like there is a black rubber thing just behind the overflow drain rather than a pipe. But it's hard to tell.
Thank you all.

Can you not remove the bath panel? Access to pipework, waste, taps and overflow etc is all usually done from underneath after taking the side panel off.

I'm not clear on two items:
Do you have to have the bath at overflow level before you notice the leak?
How do you notice the leak if you can't access the base of the bath?

Yes. Water overflowed and the water dripped from the ceiling below.

There is no panel. It's tiled everywhere.

Unless someone says otherwise, I feel the only option is to remove the tiles to access. Normally, the overflow has a connection to the bath, with rubber grommet / washer and held in place by the plastic / metal part bath-side, screwed on to it.
Failing this, perhaps remove part of the ceiling below?

I assume you have something like this? See the screw-thread at the back of the fitting.
You may be lucky in that the pipe and all pieces are still attached and the fitting has simply come loose and slid to the side.
Slide the silver bit, with the black rubber grommet, to the side until centred on the hole and then screw the silver piece clockwise until it starts to tighten. DO NOT over-tighten as you will strip the thread.

That chrome cover should unscrew, unscrew it slightly, move the overflow back to centre and then tighten it back up, oh and try not to overfill the bath
