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, greys, blacks and red.
