Trophy washbasin problem

I have just got a Trophy having had a Clubman. The washbasin in the shower area of the Trophy is the old type where the actual basin doesn't slot out but is screwed in. It also has had a small piece of wood put in to reinforce the area under the taps causing it not to open fully and is therefore on a slant.    The plastic is also quite brittle. The clubman washbasin was the Cleo unit which clearly is not going to fit in the Trophy space! I wondered if anyone had upgraded to a different sort of washbasin as apparently the old Trophy washbasin is obsolete. Any help much appreciated.
