Hey All.
It's been a while since I've posted. The permits have been received, and the builders are moving quickly! Wall is down, new ensuite structure is up!
I'm seeking some advice for the tiling of the ensuite.
I'm looking at two tone colour, with a moody colour scheme.
I've selected a Navy Blue + White and a charcoal floor.
This is the bathroom layout I was thinking and which walls the tiles would go on

The cavity door is in the bottom right of this image.
I'm busy choosing between two Navy tile options:

They will be laid vertically with a black grout and no staggering, to look something like this:

I'm making a custom vanity out of beechwood panels, and a black recessed mirror cabinet.
Now the opposite walls, I'm looking at something like this:

I was considering laying these horizontally and staggered subway style to create a contrast to the straight line navy blue.
Something like this:

I'm considering using a medium grey grout for these to pop them a little, but not strongly.
All fittings are black, and 90% of them have hints of rose gold.
I was really keen on the idea of having the top and right wall with the navy (like in the photo) and the bottom and left wall in the white. My builder has cast some doubt in my head by saying typically, you'd only make 1 wall the "feature" wall, in this case the top wall (relative to the diagram). So now I'm not sure if I would want the right wall to also be white. I worry it may take away from the look I'm going for.
I'm planning to have a low light filament globe hanging from a pendant (again, similar to image), except that it would be just left of the mirror so as not to get in the way of the cabinets. I'll also have a black long led makeup light over the top of the mirror.
Lastly, there'll be a led / extractor fan above the shower itself.
There are no windows in the bathroom, and I wanted to play to the low light rather than try and cover it up.
The dimensions of the bathroom are 2.7m x 1.1m.
Also, is it worth putting in a single bulb heat lamp right in the middle of the room. I don't want one of those 3-in-1's as I'd like the fan over the shower.
Thoughts?
Thanks
Itai
