If you've wrapped all connections in kitchen roll and they've been dry but the floor still gets wet, It could possibly be as Riley has said, a screwed pipe under the floor so remove the toilet and the fixings and see if you get wet. Failing that it could be either condensation or you need to aim better when your using the toilet 😀

Is this a raid from the tilers again ? hmmm ?
i had one like this a few years ago , after installation i tested the toilet {vanity type} with around 10 flushs , paper tissue around the flush pipe and pan connector all dry so thats me done! , two weeks later we get a phone call , wet floor! , replaced the pan connector as the flush pipe was dry , passed the paper towel test , phone call again a week later! basically i pulled the toilet out set it up on a bench and poured water through it manually so i could see the back side perfectly , turns out it was a tiny pin hole in the pottery around the flush area but not near the flush pipe , a small drip would of occured with around 10 flush's i recon , took quite abit of water to produce that one drip , that drip then adds up over a week + ...

I agree but this is op's 3rd. Not impossible all are faulty but fairly unlikely
If this isn't fixed yet, try getting a couple of bottles of different coloured food dye. Put one colour in the cistern, another into the water in the pan. Leave some white kitchen paper where the puddle forms and wait...
This should narrow down your search area a bit.
Note added later: I've had great success using dyes for tracing the source of difficult leaks but keep in mind that they may stain some types of finish. So, if the bathroom floor has been done with in Carrarra marble tiles at a gazillion quid a square meter you probably don't want to use this method without thinking about how to protect the finish. On the other hand, a leaky bog is a problem that has to be fixed somehow.

When it has leaked - all pipe work leading to the toilet cistern and waste are dry and if it’s comming from under tiles would I not have a wet patch on the ceiling below?
Only thing I think of doing is taking the toilet completely out and see if it leaks from
Somewhere else ?
Better bathrooms
Thanks for the reply we are worried about damaging the tiles like you said but may end up having to do this
This is probably your best next step.
If I've understood correctly, the leak happens at night and not when you're around/using the toilet? Using two different coloured dyes as recommended by @Chuck is a great idea, but you're concerned about staining your tiles.
You could try this:
cover floor surrounding toilet with kitchen towel (up to a couple of feet distance from it), cover where the pan connects to the soil stack with kitchen towel, place kitchen towel where the pan & cistern join, surround the pipe that supplies water to the cistern with kitchen towel.
Then the "fun" bit starts, set yourself a timer to go off every 15min and each time it goes off inspect the kitchen towel without disturbing it, until there's an initial trace of water.
Its time consuming and a lot more hassle than using dyes but won't damage your tiles. It will also show you whether the water is coming from somewhere else, hence surrounding a wide area around the toilet. Once you've narrowed down the location the water is coming from report back and we'll see what we can do.
I’m sure I was the first person to say this!
Err how when your original post says "As above ...................." 🙂
(Please note I have no wish to argue or start a willy waving contest)
Well thats cleared that up. Do you get an extra point for being the first to suggest something nowadays. 😀
People sell UV tracer dyes that glow under UV light but are otherwise invisible. For example:
https://www.amazon.co.uk/Invisible-Blue-Reactive-Water-Dye/dp/B00KPF5A3M
I've never tried these myself and I'd definitely do a test on a relatively invisible patch of any surface you are worried about.
So that's what you get up to in the Plumbers' Arms...
This can happen as a result of a combination of two independent faults. Firstly the float valve is set too high or is faulty and is letting by. When not being flushed, the level in the cistern creeps up. Secondly, the overflow has not been installed correctly and leaks when the cistern level gets up to the outlet...
I always test overflows for leaks and proper operation very carefully. Once bitten, twice shy...
My apologies if someone else has already suggested this. There's a lot of noise on this thread so I might have missed it.
Shhhhh it’s a secret
