I am looking for this rod for my alcove bathtub. Does anyone know what this style is called and/or where I can find one? As you can see it is more of a notched than straight again. Bent to go back a but towards the end than straight. Not a curved rod. Not a corner rod! What the heck is it called! LOL (I am actually doing almost this exact bathroom.. will post photos later. Coming along nicely! )
