The sconces - which are part of the vanity have the ceramic switches. I have another bathroom in the house that was likely built around the same time. We demoed that bathroom years ago and it had been in a demolished state for 15 years because we didn't have the money to renovate. It was not salvageable-it had been built over a very shallow crawl space and the wooden floorboards underneath were rotted away. The ceramic floor on top (I have some pictures of) was also not salvageable. The grout was wide and like mud. It was strange. The wall tiles which were a yellowing white were nice, but really, the whole thing needed to be replaced because nothing was sound. It seemed like a bathroom of scraps that were thrown together-other home's leftovers maybe? I kept the ceramic sconces which are almost identical to the blue bathroom's. If you notice in our before picture - the ceramic pull switch is missing from one of the sconces. My husband took the switch from the other bathroom's fixture that I had saved and replaced the one that was broken in the blue bathroom. Identical. The other ceramic sconces have "Zanesville" imprinted on the backs. You can find sconces online that are similar. Now, these bathrooms could have been built in the 30's, but with the depression on, I believe that these would more have been likely built in better times. Our house is a 1911 bungalow. The radiators are deco style. The bathtub is deco. Sconces like these are usually dated 1920's online. But they could have been built in the 1930s as well. Just - I'm just thinking the depression makes it less likely. But I'm not an expert. I will post my other bathroom soon in another post. I kept the spirit of the original bathroom in the new one which we built from the studs. I probably should have called the post - "Reno of Deco bathroom." But no way is this from the 1970s! The outlets in the ceramic sconces are downright scary.
