I'd match the wall to just match the vanity in height and depth, and the custom glass screen for the rest of the wall and door. It is a bit of an awkward shape.

Thanks Louise. If I take out the external door in the bathroom, I would still like to have an external door somewhere on that side towards the back of the house, so that probably means reducing the size of the bathroom so that I can put a door off the living area where it would fit best like the sketch below. In that case I am worried that the bathroom space is quite small to be a reasonably spacious family bathroom, even if I "pinch" a bit of space from the study next door by designing that room around it. (I think this would still be cheaper than moving the family bathroom to the current study, which is a larger room but would need to be retro-fitted with plumbing etc... - but that is one alternative). Appreciate any other thoughts.

I don’t like layout as wasted space near window and don’t like shower near door cos of wet floor. Depending what you like and don’t maybe put loo under window backing up to other bedroom wall and swap shower and bath

Well since you asked it lacks any design flair. It is quite a well sized room but has issues. It seems strange to me that with such a good size you are limited to a semi-recessed basin and a narrow vanity which is more appropriate in an apartment bathroom rather than a functional family bathroom. On opening the door the first thing that you see is the side of the toilet - I try and design toilets to be in a more discreet location. It looks like there is a full height wall adjacent to the end of the bath which divides up the room into two pokey spaces. There is isn't a lot of convenient towel rail space for a family bathroom. It looks like everything has been plonked down without much thought. Seems like a lot of wasted space and wasted opportunity for something that could be much nicer and much more functional if you had a bit more design thinking...
