Mimicking a 1920s era bathroom, replace wall tile with white ceramic subway tile, embellished with a single strip of black pencil tile just under a top row of white, bullnose subway tile. Grout with a medium gray or charcoal gray. On floor, install black penny tile with white grout or a charcoal and white patterned tile. Ceiling fixture - a schoolhouse-style semi-flush pendant. Wall sconces in brushed chrome with white globe echoing Art Deco theme. Make sure to include soap holder in tub/shower and room between wall tile and bottom of bathroom mirror to install shallow shelf for sink essentials.
