This ‘accessible’ stall is about 36 inches wide and about 50 inches deep. An accessible stall with a floor mount toilet needs to be 60 inches wide and 59 inches deep. Horizontal grab bars should be mounted alongside and behind the water closet between 33 inches and 36 inches high. Back to the question: “What is wrong?”. The stall is too small, there is no handrail behind the water closet. The handrail alongside the water closet is not horizontal.
