I like to have an Art Deco bathroom (around 1930) but I don´t know the fashion in detail at that time. Do you have any recommendation?
Art Deco style is a clear straight style. Very often you find a checkerboard floors, straight or diagonal setting. On the walls the tiles are mostly white in a straight setting combined with different kind of borders on top or below the top line.
Favourite coulors in Art Deco were black and white. Sometimes yellow was incorporated as well.
