My plumber installed a wetroom aquaboard (impey), he put waterproofing on top (BUT DID NOT FULLY WATERPROOF THE WHOLE BATHROOM). ( I DID QUERIE THIS BUT WAS MADE TO FEEL LIKE AN IDIOT). He then tiled on top and put a glass screen to the side. I have not used shower as there were problems with fitments. These have now been replaced. Can anyone advise if we put silicone along bottom of glass screen will this be sufficient. Or do I have to rip out whole bathroom and tiles. Any advise would be very helpful. Thanks
