What color shower curtain and wall goes with baby pink tiles?

Answer 1

When faced with a permanent fixture, such as tile with a colour you would not have chosen, you have two options.

Work with it, find a patterned shower curtain with a small amount of the pink (or a closely related shade) in it.

You could showcase the pink by using a white (or be bold an use black) shower curtain, as long as you use more of the pink in other parts of the room, you're fine.

Or,

You can ignore it. Pick a solid colour shower curtain to your own tastes and keep it closed most of the time.

I personally do not recommend the second option, but I know many who do.
