Hi, i have an interior opening of about 47 1/8" with the frame, and 48 3/4" taking the frame out. There used to be 2 slider doors there. The guy that was doing work suggested a 48" double door for this opening, but i don't know. Is this a good spot for a double door or should i go with a big single? There is sheetrock on both sides. This door will go into our master bedroom.
