It looks stunning, you must be happy! I think the orchid alone makes a statement inside particularly against the mirror. Have a look at these pics from lush zone which may give you inspiration for the terrace.

Just for inspiration, as I don't know your budget, how about something like this? http://www.plainenglishdesign.co.uk/arts-3 or these http://www.neptune.com/furniture/bathroom/washstands-taps/ I find most off-the-shelf vanities in the UK are either hideous and cheap-looking, or nice but cost a fortune. Fired Earth is another that's expensive but has good country styles. I would probably get a carpenter to make something bespoke with a marble top. I'm having my bathroom cupboards made in moisture resistant MDF, but I want to paint them so it doesn't matter that they're MDF.

Hi minipie, thank you for confirming what I felt was right in my gut :) The bathroom is a family one and is used mainly by my 3 fast growing girls , so I have to keep in mind that they will be performing their beautifying in there in a few years! Would it be totally ridiculous to move the vanity right up against the window so we have equal visual space and I have more room to put lights on either side of the mirrored fixture? I have about 30 cm on one side and 10cm on the other side of the vanity ( not nearly enough to comfortably install side lights). If I butt it against the stud wall, 30cm on both sides of the mirror and 20cm on both sides of the vanity. Hope I’m making sense?

What an amazing bathroom! I'd suggest using a 90cm wide shower (and perhaps 90 deep and/or quadrant/corner, because of wet feet when stepping out in front of doorway), as there's 10cm on the side for the toilet drain (and some hacking into the chimney plaster to get to 110mm pipe +surround*). Then 80cm width for the toilet. Which leaves 100cm for a vanity. *) and if you can find some of these architraves+alike, you could widen the chimney breast so the 10cm won't look lost. The positive with a faux low wall (for toilet cistern) behind the vanity, is that any dresser can be turned into vanity without losing too much drawer space, as the drain+gooseneck can go behind instead of through. And a cabinet over the bath would not be ideal, just use the vanity drawers and for the smaller things hang some sleek looking mirrored medicine cabinets. Perhaps a towel rack above the bench. Or replace the bench for a storage bench or chest.
