Bath Re-tiling. In this case the tiles were old and the grouting had failed at the shower end of the bath. As a result the board behind the existing tiles had rotted and gone mouldy.
Once all the tiles had been removed I removed the rotten board and replaced with a cement tile backing board which is far more resistant to damp.
The bath could then be re-tiled and grouted and then the shower screen could be put back and all edges sealed with silicone.Click on images below for a slideshow.
