Having made no further progress in nearly a year, In December 2012 I finally had another burst of motivation around the time that I started on the flat roof and made more use of my free skip by pulling down the ceiling.
I had also made some further progress by removing the toilet, bidet, sink and shower cubicle, this all went into the skip as well.
I also removed the plaster from the walls near where the old sink was located.
This picture shows the shower mixer and pipes hanging from the ceiling.
