Hi
I too have had a problem with this, as have a number of others by the sound of things.
As i understand it, it is down to the 'Quality' of the grouting around the bath.
I didn't get anywhere with the builders as it was months after we completed that we became aware of the issue, even though we are visiting almost every month.
I intend to regrout the bathroom but in the mean time I have filled the bath with water and the applied Silicon sealant around the top of the bath and allowed it to dry.
The mould wasn't too bad in the bedroom and it cleaned up quickly, i went over it with a coat of paint and this seemed to sort it out.
Hope this helps.
