Most towel bars start at 23 inches wide and can go up from there, however small bathrooms would usually be better served with a shorter bar. Look for towel bars that are 7 to 17 inches in width
, which can accommodate about one average size bath towel. If wall space is limited, maximize the towel bar by placing a hand towel on top of your bath towel instead of installing a separate bar. Double towel bars
or swing arm bars
are good options if you have a small width to work with, but need to hang more than one towel.
