My mother's 1960 MCM home has an American Standard wall hung (yellow) toilet. After noticing a small amount of water underneath, she contacted the plumber, who found that it is cracked and needs to be replaced. We are now on the hunt for an American Standard wall hung Norwall toilet, preferably yellow but will consider any color. Does anyone have leads on where to start? (My mom is in her late 80s so I am conducting the search for her.)
