I need advice on ideas for a "fixer upper" bathroom. The tub is colbalt blue, and the counter is a taupe color. I unfortunately cannot afford to replace the tub, and was having a hard time figuring out what color to paint the walls etc. I had planned on removing the bathtub glass door and replacing with a curtain. Possibly painting the cabinets black. Unsure what to do for the walls and doors. Any help or other suggestions? The rest of my house is mid century design.
