I would put it on the wall behind the dining table, turned the other way to how you have it in the other photos. Take the small pics away from that spot and away from the wall near the christmas tree corner and group them all together on the wall between the 2 windows. find a large piece or 2 of art for the wall near the christmas tree. Thats what first comes to my mind to do. Its not to busy at all, Brandi is correct, the pictures are too small to be so far apart on a large wall.

It looks like the one Charlie Albone did was a plastic screen (Bunnings) adhered to a mirror. Im not certain what type of mirror he used. You might be able to find large acrylic mirrors through plastic suppliers. These would be suitable outdoors.

have a shorter recessed wall cabinet for storage and if necessary have the balance of the space fixed mirror.....you should find something suitable at a fraction of the cost of custom made but strongly suggest that you don't have the vanity hard up against the glass screen (a gap is useful for hanging a hair dryer or hand towel and allows easier access to clean the glass screen) we've been disappointed with custom made vanity and wall cabinets which were more than twice the price and no better quality

Thanks Margot. I think I've more or less got it sorted. The only challenge remaining, I think, is finding a way to give it a visual lift. It currently has floor to ceiling tiles in a standard size, square, and a very uninteresting colour with no texture - but in very good order. Very dull! I hate grout in showers so I'm thinking maybe some Mr Wetwall panelling or something similar over the tiles in the shower and on the new wall formed by moving the linen cpd, plus on a part wall along the long side of the shower to replace the glass screens that I insist must go (I'm a lazy cleaner and I hate cleaning glass!) Hopefully that would be enough to relieve the dullness of the existing tiles. Then some feature shelving over the new bath tub perhaps. Not yet decided whether to install a freestanding back-to-wall bath or a drop-in, but the latter might provide scope for some more feature tiling or panelling around it. I want to open the room directly to the outdoors but the current window opening is only 1200mm wide and the wall is 8 inches of solid concrete - not easy to cut to enlarge the opening - so I'm looking at either a hinged door with window inset into it or a standard size glass swing door with a narrow window beside for ventilation. My other challenge is doors for the relocated linen cpd, as the existing mirror doors have got to go! I loathe them. As the cpd will be visible from the living area, it needs stylish doors.
