We have a persistent leak next to our shower door, in the actual plasterboard bit that connects to the shower door in the en-suite shower. Its just above the skirting board on the lower right hand side and the plasterboard gets absolutely soggy whenever you have a shower. We first thought that the leak was due to the silicon not being sufficient around the inside of the door and the shower basin but no matter how much we have had new silicon put down...we still have a leak. We cannot use the en-suite at all now.... has anyone else had the same problem? If so, what was needed to fix it?
