Where is this leak coming from?

BrokenJetpack

So I got a new en-suite a coupe of months back, and I realised it had a leak after the work was finished and I had already paid the guy that did it. I got back to him but he stopped responding to me. Since then I got a handyman to look at it, and we tried to narrow down the source of the leak. We're pretty sure now that it's coming from the bi-fold door in the shower, as opposed to the drainage pipe underneath the shower, etc., as we poured water directly down the drain and also on the tiles without hitting the door. Some pics:

The leak is coming from the corner of the shower tray on the right side as you look at it. The door seems to be installed fine and I can't see any cracks or holes anywhere. It was siliconed on the outside and also had a line of silicone on the inside along the bottom of the tray, underneath where the door sits. I recently read that these doors shouldn't be siliconed on the inside, so I scraped off the silicone between the door and the shower tray.

Can anyone suggest the most likely cause of the leak? My DIY guy said the next step would be to remove the bifold door and frame completely, and reinstall it.. does it make sense to do that?

Hi! The usual place for these to leak is at the junction of the side rail and the shower tray, water gets trapped between the exterior and (incorrectly installed) interior silicone and permeates down the side of the tray. In your case there you appear to have a 10mm gap between the lowest tile and the tray, that's the most likely point where it's leaking. Really there should be little or no gap between the tray and tile and a bonded seal right behind the lower parts of the tile so that the water can't progress downwards. Then the side and bottom rails are sealed from the outside, giving no path for the water to leave the shower.

You'll see the method of applying a Classi-seal around the tray in the images here:

It's defective workmanship, simple as that. You have the option to seek redress through the small claims court, but you really need the tradesperson to come back and rectify the work by repairing that seal. Tell him that you're considering that route now, maybe he'll take a change of heart.

Water is going to get into the frame, so you need the water to exit at the bottom and back into the shower tray, silicone the outside of the frame, remove the silicone at the bottom on the inside of the frame.

Try calling him with a different number he doesn't recognise. If it rings out don't leave a message, let him call it back.

Thanks for the answers. I scraped of all the silicone along the bottom of the frame and ran the shower again, but it still leaked.. seemed to leak more water if anything.

Am I right in saying the frame should be siliconed to the wall (red line), just not along the bottom? Should I also remove the silicone where the door sits into the frame (green line)?
