Hopefully the doorway/walks are offset so that there isn't a direct line of sight from double doors through to toilet... Is there space at the foot of the bed for a small seating area? Lots of pics with this set up can be found on houzz to give you ideas. I would be inclined to move the bed towards the front windows and have a sitting area as the focus of anyone passing by.

Personally Id choose cabinetry flooring etc first as these are the first things to be installed. Wallpaper is nearly the last thing to be done in many cases . it is also the easiest to change and will most likely be changed before the rest of the room ( eg Tiles & Cabinets) in the future. Happy to talk to you to discuss your options

personally I would stick with the silver, it's timeless. A round mirror would look good.

Amazing transformation! It has a real peaceful and relaxing vibe! love it!
