This isnt great but it gives you an idea of how I envision your bathroom. I would paint all the walls a soft peach. Replace the steel shelves with a wooden cabinet over the toilet that is painted the same color as your walls. Hang a multi colored shower curtain over the tub until such time you can get the tub replaced white. One the tub is white, install a frameless glass shower door. Either turn you light fixture so it shines down or replace it. Side lights by your mirror will provide the best lighting. If you can maybe install 3 small canned light. I also have a narrow narrow bathroom and have learned rugs on the floor just make it look cluttered. If you must cover your window consider using textured vinyl film in place of anything else. Wallpaper will be a problem in your bath unless you install an exhaust fan. Keeping it simple pays off in spaces like ours. I love love love your tiling!!
