I have a 1938 home with black and white tile in the bathroom. Of course, the wall tile goes only about 5 feet up the wall in the tub, which now includes a shower. The previous owners put up mirrors to complete the proper height for the shower. It looks hideous! I don't want to "disturb" the existing tile as it is in great shape and is old. It has white square tiles with a black border. Does anyone have any ideas about adding something water-proof in place of those mirrors so that I don't have to disturb the tiles, but keeps the bath looking "period" or at least will be complementary to the tiles? Any advice is greatly appreciated!
