That layout sounds kind of like what the 2 bedroom units in the HOA I lived in when we were still in SoCal was like...The vanity area of the bathroom had a closet facing the vanity/sink side that was the two sliding door type, with a door to the toilet/tub+shower part of the bathroom to the right (left if you're coming in the door from the master bedroom) and a door to the master bedroom on the left (right if you're coming in from the toilet/tub+shower part of the bathroom) - another double door slider closet was in the master bedroom. They almost always painted all of the walls, the closet doors, and the doors in/out of each space the same color as the master bedroom because it was adjoining. The smaller bedroom accessed the bathroom through another door off the upstairs hallway, so sometimes that smaller bedroom would be painted a different color but not always. White (the same one as was used elsewhere) was a popular and sensible choice, you can always add color with accessories and art! White bedding can start to look dingy if you don't wash it in hot water (occasionally adding bleach to go into the load while it's running), so think about how much 'maintenance' you're willing to do before buying all the bedding in white (sheets and pillowcases in white aren't as big of a deal because you typically have 'decorative' pillows and a comforter/duvet covering them when you get the bed made each day). :) When we had the house on the market the 'stager' had us buy one of those cheap bed-in-a-bag comforter/shams/decorative throw pillow sets in white with a little area of patterned print down at the part that goes on the foot of the bed, which I thought was totally impractical given that our dog loves being on the bed and washing the thing would have made the fiberfill migrate around so it would be lumpy when it went back on the bed! At least the place sold in less than a month after being listed so we didn't have to worry about it for very long. :P

I honestly would just do white and good LED 4000K lighting so what you put together will look the same outside .

Great job so far! I like the idea of using wallpaper, but it might be a huge pain, so I’d paint. I painted my closet light gray, though it’s mostly covered by clothes and shoes now so you can barely see the paint. Might not be worth it. If you’re planning on using this as your makeup prep spot I’d invest in a nice LED mirror with a dimmer, it has been life changing for me! I also have a smaller magnifying mirror (suction cup so it isn’t permanent) and I use both of these mirrors daily. You do have a nice big window there, so floor to ceiling treatments would add a bit of flair and elegance to the room. I would go darker gray not light gray for some contrast. How about maybe even plantation shutters there? These are in my dining room but something like this would look nice.

I too am trying to identify the customized closet systems in my new condo, so I can buy some additional shelves. I can't believe they don't put their name or logo somewhere ! I too have those oval hanging rods, but my shelves are on moveable pegs for support (thankfully).
