What a great job you did. So good that you just went with white. The concrete floor tile on wall behind the vanity would have been too busy after now having seen the finished product.

Silk would be interesting, not to mention elegant. As for paints, the Silver Illusion appeals, but it might throw green (not sure). I also agree the Tranquil Retreat is a good one. I'm wondering how big the feature wall is, and what is going on this wall, eg TV, fireplace, large artwork, etc.?

Thank you all for your reassuring comments. I agree, in the midst of building you're in the 'zone' and small things can be made out to be bigger things. I guess it is all about expectations - expecting one thing and getting another. I now feel more content with the finished feature wall, based on all your comments. Many thanks!

I did that in one of my bathrooms but the feature tile had more pattern (warm Grey brown streaks) so looked softer than the all black against the white walls
