This morning just as I was leaving for work I noticed a brown stain on the living room ceiling, which is below the bathroom. Almost certainly a leak I would have thought, although the ceiling was dry. Had a very quick look under the bath - no obvious signs there although did notice the grout between some of the ceramic floor tiles at the end of the bath were wet - there may be a leak coming from the shower screen onto the floor - although I'd have thought that was unlikely to have caused it as it would have to get through the tiles/grout under which is chipboard floor under which is insulation before it gets to the ceiling below. There is also a slightly loose seal on one side of the bath to the wall but again for the same reasons I'd have been surprised if this would allow water to pass through chipboard and insulation so readily. It seems to me more likely to be something which is already under the chipboard floor? There is a radiator in there so potentially the pipework for that could be the cause. Rather annoyingly phoned my buildings insurance this morning to see what we would be covered for as had read that it's easier to go from the ceiling upwards, but we are not covered for what they call "trace and locate", so we are covered for damage caused by a water leak but not for any damage caused by looking for it! So if we wait for the ceiling to collapse we are covered but not if we put a hole in it ourselves!
I'd be grateful for any advice/tips of what else I can look for here. Thanks in advance.

Try testing the ceiling with a cheap (under £10) Moisture meter first to give you some idea of the problem of the leak and where its located.
Could just be someone splashing about in the bath or shower.

Grouting and bath seal, you'll be amazed at how water can get through. P.s. Is there a shower above the bath?
 
Take your bath panel off and spray your shower at the seals round the bath, sometimes the weight of someone standing in the bath can open up the cracks in seals and grout

Thanks all. I believe I have found the problem. There is a cracked wall tile bottom right, under the shower. Even though I have previously sealed this it is leaking from there as I have taken the side off the bath and watched underneath while someone is in the shower. It doesn't happen when running the shower on its own so it must be the splashback effect bouncing off the persons body into the corner. Underneath the bath the chipboard floor is pretty saturated so I am sure this is the cause. Question is how do I fix it, I'm a little reluctant to replace the tile as a) I'm not sure if I will get one to match and b) part of it goes behind the glass shower screen to the right. Will a waterproof bathroom sealant do it (although I think that's what I did before) or would a clear silicone sealant or something like that be better? Thanks again everyone.
 
Here are some pics showing the cracked tile and the area underneath the bath.
sorry if they come out the wrong way up, trying to do this on a smart phone!
