Not sure why there was a piece of copper pipe sticking out of the wall above the bathroom door, but it had to go.
Step 1 - battle with the huge amount of silicon that has been packed around the pipe, in order to get it out of the wall.
Step 2 - Find something to fill the now quite large hole. We unbelievably find a scrap of dowel that fits perfectly.
Step 3 - Fill the rest of the hole with some fluffy filler.
Step 4 - Sand and paint.
Now you see it, now you don't!
