Hi, we have a rectangle three walled tiled shower with acrylic base that is leaking in both corners - was only built approx two years ago so really not wanting to replace. So far have had the original plumber and tiler look at it but couldn’t find the source of the leak. Silicone where the tray meets the tiles has just been replaced and pipes tested. Anyone else seen a water pattern like this? We are at a loss as to where it’s coming from. On one side the water didn’t appear until a few hours after the shower so could be travelling quite far.
