We recently renovated our bathroom. We have gray floor and vanity, and white subway shower tiles with an off white wall (Silver Satin from Benjamin Moore). Brushed nickel hardware. After reading a few designer blogs that were in favor of mixing metals, we installed the oil rubbed bronze glass shelves to give some contrast and warmth to the cool palette. I keep staring at them. Should I exchange them for the brushed nickel brackets or do they work? If they do should the shower hook we will install on the opposite wall also be oil rubbed bronze or should it be brushed nickel? Help please.
