Loved the kitchen splashback, my supplier has some similar that look like 3D, really nice. I did a feature wall in a bedroom about 4-5 years ago in Porcelanosa 90x30
Nick Knowles said it took 3 blokes, 2 days to do that split face fireplace. That's quite a long time! To be fair, it looked ok from what I could see, they'd interlocked the returns around the corners and it looked like it'd had a coat of sealer.
I wasn't too sure of the wood behind the bed going across the ceiling a little. Thought it would look best just up to the top of the wall.
Wood tiles on walls seem to look better than on the floor sometimes.
Not sure I could sleep with a 1.2 X .2 porcelain plank above my head :/
