We selected a Torsion shower door set for a fully tiled bathroom. The information sheet says "Wall retainers must be installed onto the waterproof membrane prior to tiling." However, our builder had the tiler come in and fully tile the bathroom before installing the shower door set. They then installed the shower door directly onto the tile. The shower stall has always leaked and the builder has returned and added silicone trying to stop the leak, but it still leaks. The water seems to be coming out at the bottom corners where the glass meets the shower tray.
The builder mentioned they may have to remove the door set completely and reattach it to fix the leak. Is there any hope of this working? Will they have to remove the tiles? I'm losing faith in the builder's knowledge of what they are doing.
