604.5.2 Rear Wall. The rear wall grab bar shall be 36 inches (915 mm) long minimum and extend from the centerline of the water closet 12 inches (305 mm) minimum on one side and 24 inches (610 mm) minimum on the other side.

There are some exceptions. One of them is for when the flush valve interferes with the location. This could be if there is a bed pan cleaner at hospital paitent rooms, or at children’s toilet when the flush valve is required to be higher.

EXCEPTIONS:

2. Where an administrative authority requires flush controls for flush valves to be located in a position that conflicts with the location of the rear grab bar, then the rear grab bar shall be permitted to be split or shifted to the open side of the toilet area.

The exception, though, can ONLY be taken IF there is an administrative authority that requires the flush control to be in a specific location. Therefore it is not IF we specifiy a toilet with a flush valve which interferes, or if the contractor locates them in the wrong place. There must be a reason that would make it technically infeasible to achieve the required mounting location.
