This is a great space with lots of little details. The wall with all the nooks is a great idea. Also, the tub surround is bigger than the tub and gives some space. The tile around the tub gives some visual interest.
The raised bar surrounded by the lower bar is a great idea. Gives plenty of space and lets people sit comfortably at the bar and interact with someone working in the front. Lots of storage space.
I love the wood beams on the ceiling. It gives the neutral space some texture and color
The barn door is great alternative to a regular door and is easier than a pocket door.
Love the color and style! Make a statement!
Use that paint!
