About a year ago I had a a big renovation done (using professionals) and this included new central heating, plumbing and bathroom.

2 jobs I had to finish on my own was installing the bath panel and putting a doorstop into the bathroom floor. This was right at the end just as I was about to move in. There was no one living there at the time and the bathroom was not in use (no one has showered in it)

After I had just installed those 2 items (including putting screws into the floor) I got a water leak from the bathroom into the kitchen below.

I assumed it MUST be related to what I had just done as I had screwed into the floor. I got a good flow of water going into the room downstairs (kitchen). I drained the boiler and called a central heating guy in the next day. The water stopped coming through when i drained the boiler so logically I thought it was related to that.

The central heating guy spent a good 3 hours at my house doing all sorts of tests. You can see in the photo he drilled a hole into the floor - we also then took up a big section of flooring to look for pipes.

I was 100% sure there were no pipes when I had drilled because I had photos of where all the pipes were and when we lifted the floor we found no pipes. The boiler was put back on and I have not had the same leak in the same way again (i.e that much amount of water). So I am happy that it is not a boiler issue. The central heating guy did not find any leaking central heating pipes.

Fast forward about 11 months and I hadn't got round to putting the panel on (as the vinyl floor needs replacing). I am just about to do that job now.

I consulted a family member about whether there had been any leaks in the past year as I had not seen any and the only time was when we had my sister and her children staying and they were showering - but the water coming down was not as major as the original leak. This gave me a clue that the leak or A leak it likely down to when the bath is put to extreme use as we don't normally have children here and they will have filled the bath up/splashed water all over etc.

I came to the conclusion therefore that the water is somehow getting out of the bath and going through the floorboards. I have rock wool insulation in my floors which is quite solid and this means if water goes through it will not necessarily go directly through the ceiling below as it can travel - that said the bath is almost directly over where the water was coming in downstairs.

So anyway, I checked the bath properly and it is all silicone sealed in and I then tested the bath taps, waste and the handles to see if water was going through by putting the shower on them for extended periods. I noted that the handles are allowing water through.

This is what I need help on.

Here are some photos.

Water is leaking through one handle hole on the outer side and possibly both on the other side.

You can see the bath has water staining on the green side and also a wet path under the handle. Photo 7

The water from the other handle is the water under the 2 copper pipes. Photo 8

What is interesting is that the water from outer handle (closest to me taking photos) is coming down the bath and almost directly under the handle whereas the water from the other side seems to be coming down to the middle of the bath - I put this down to the possibility of there being more water from the other side.

Now whilst showering there will be spray and small amounts of water will go through the handles. I tested it out to quite extremes and we are talking very slow drips.

As far as solutions go - I can take the one on the outer edge and silicone it . But the problem is the other side. Possible solutions

1) rip bath out and fix - not going to happen

2) try and get around there with some tool to seal with silicone or some other product - - will be very hard to do if not impossible.

3) put some form of waterproof material down - like my old vinyl floor and leave it - so when water does come down it cannot go into the floor - I am not sure if it will evaporate though or just store there forever until it builds up and eventually finds a way down.

Views?

Now the other annoyance - and why I gave the whole story. Even if the bath handles have been leaking from day 1 - there is no way they were responsible for the leak I originally had last year as the amount of water was way more than what the bath handles could let through - in addition we were not using the bath then.

The central heating guy offered 2 suggestions

1 - someone had dropped water and it went under the bath - a possibility - but at the time we had no one in and no one has admitted to it.

2- water may have come in as rain via some openings I have for pipes in my walls - but this is unlikely and also it hasn't happened since.

So as to what caused the original leak - remains a mystery.

The only other possibility - which I will find out when I screw the floor back down (currently just loose under the vinyl) - is that the screws/floors may be putting pressure on something further down which may cause the leak again when I put floor back - but this seems long winded also!
 
1. Is the one I'd go for.

2. Is not going to work.

3. Please don't. You'll end up with wet rot or some similar health hazard living under your bath.

It does look like a lot of water to have come through the handles but, whatever, the seals need replacing and fitting correctly as per manufacturer's instructions as they definitely shouldn't leak when sprayed with the shower.

Rain penetration is a bit of a stretch but if the builder forgot to seal the openings, maybe. You can use this excellent website

Weather Forecast & Reports - Long Range & Local | Wunderground | Weather Underground

to check weather history. (Type in your postcode and a start date and get half-hourly readings giving the temperature, how much rain, wind direction and strength, etc.) and see if your leak correlates with a period of rain with a strongish wind in the right direction.
 
The bath cannot be taken out - it is too major a job.

What about a thin layer of silicone on the inside? the handles look well sealed to me but there is no doubt water is coming out because i can see it on the side that is easily accessible and you can see the water marks anyway on the side of the bath.

Anything else is a bodge and won't last even if it does work for a while.
Looks like that bath hasn't been battened anyway, whip it out, batten it up, fix the handles and pop it back in.
If you want to try and silicone the handles then fill your boots, just make sure nobody uses them as handles afterwards or the movement from the weight on the handles will break the silicone seal and you'll be back to square one.
I know you want a quick fix, I don't blame you, but there's only one proper way to fix your issue, and adding battens will stop the seal against the tiles from going prematurely too.
 
When I first moved into my house, it was a new build. Both handles on my bath were a little loose, to the point where my son trapped his hand. I contacted the builders and they sent a young man. He managed to crawl round the bottom edge and stretch up and tighten the handle at the back. I cant see from your photo if that's even possible.
 
While you are sorting things out, check that the pipes are supported and clipped at the correct intervals and the waste has the correct fall. From the photos, which may not tell the whole story, everything looks as though it's hanging in space.

Edit: For the original big leak of unknown origin, if you can't figure out the cause with reasonable certainty you might consider using a battery operated moisture detector as a watchdog to let you know when it next happens.

Since you know what got wet last time you know where the sensor needs to go. I've not used or seen this model myself so caveat emptor. (Sorry it's the US site, Google is not giving me UK results at the moment for some reason.)

In answer some questions

1 - the bath does have battens around it

2 - the pipes and waste are sufficiently support - they are clipped at one end and on the other end they are supported by ends as the pipe goes underneath the floor. The waste is supported one end by the trap and the other end by going out of the wall.

3 - access to the back will be too tight for a human! Maybe with a camera and specialist tools you could get behind to tighten a nut up but anything else would be difficult

I have noticed the handles have little grub screws under them - what do they do you think? I would have thought the bolts on the outer edge would be the connection? Perhaps if I take the grub screws off and there is some form of connection in the bath I can squeeze some silicone in?

My *guess* is that if you take them out the chrome handles will come off leaving an anchoring stud, which the gasket sits round. As far as I can see from the photos the gaskets are shaped to match the handle but may have been put on the wrong way round. If you know the make of the bath you can probably get some replacement gaskets and a set of fitting instructions.

Put the plug in the bath before playing with the grub screws. Murphy's Law guarantees that they'll roll down into the waste trap at the first opportunity. :)

Take it easy with the silicone sealant. If the gaskets are correctly sized and fitted sealant probably won't be needed.

OK had a further play and I could be saved by some good handle design?

The grub screws do actually release the handles without having to undo them from the back. so I am thinking just undo them and put silicone inside the joint - that should work longer term shouldn't it?

How do I clean off all the rust and crap?

It looks like the holes have been made too big.

I think you are right - only concern now is if i take the grub screws out on the harder to access side will the anchoring bolts move when i take the handle out because they will not have the support- it all depends how tight they were fitted.

It looks as though the stud is zinc coated so I'd either leave that alone (if you scrape off the zinc it will rust) or preferably get a replacement from the manufacturer. As long as it stays dry, which seems to be the designer's idea, it should be okay.

Again, I'm guessing, but I think that the assembly order should be stud with small circular seal into bath and secured with back-nut. Then large gasket over top of stud making seal between bath and handle and secured with grub screw. This would mean the primary seal (the larger gasket) can be replaced as a diy maintenance job without having to take the whole bath out.

It looks to me as though the original installer misplaced the larger gaskets under the stud. If I'm right and you're lucky, you'll be able to ease them out and then tighten up the stud without the nut dropping off the back. If you make a mistake and can't tighten up the stud using the friction between the back-nut and the bath then the whole thing may have to come out.

Remember, I've only seen a couple of photos so I may be mistaken.

I would think a plumber or car mechanic used to working at awkward spots could get at the nuts at rear using the right tools, plus a light and a mirror. I know I have achieved it on similar jobs. The bath waste pipe could be removed to gain space temporary
Check also that the bath definitely doesn't move away very slightly from tiles when some person stands in the bath. Batons should prevent movement, but only if they have been installed exactly right
 
The bath has been in use for 11 months or so with no issues. So happy with it at the moment.

I will have a play with the easily accessible side to see what I can get away with - if the original bolts are tight it should be doable. - if I can splodge some silicone in and push it shut again then i think I should be OK.

There is some space on the end of the bath where it has some space where we get get tools in as opposed to going udner where the waste and copper pipes are.
