Tiling round a quadrant shower

12mm is not an acceptable gap to try and cover with Silicon! I think from the photos we all know it’s not been tanked, and it’s almost certainly had underfloor heating fitted onto ply wood and then tiled. Tanking isn’t mandatory so really you can’t pull them up on that.
