So, we just finished remodeling our guest bathroom like yesterday. The house is 1920, returning each room to the period, we tiled the floor in the bathroom a small matte white hex with light grey grout, the shower wall is matte white subway tile with white grout. The entire house is painted a monochrome bone white, including that bathroom pre-renovation. Did I just create a faux pas with mixing cool and warm colors? The new vanity is an old radio cabinet painted a neutral slate blue that can go either way (I think) with a white porcelain sink that sits atop. I'd hate to repaint and change the color just in that one small guest bathroom. Also, we are adding individual beadboard slats for a higher than usual wainscot that I had planned to paint all bone white as well.
