OK we found a bit of spare time and attacked the bathroom with hammers. Result: removed the chimney and now have space to put in the bath.
I have also brushed up on my ShipConstructor and AutoCAD skills to model the pipework that we are going to need to put in and to check that there will be space to fit all the items we want to get in. For the techies, the initial modelling was done using Maxsurf (during alpha-stage debugging). This was then exported to ShipConstructor (which runs inside AutoCAD to do the detailed modelling and pipe layouts.
