"Height Placement According to the NKBA, a wall-mounted toilet paper holder works best if installed 26 inches above the floor, on center. "On center" means that the center of the holder, as opposed to the bottom or top of it, is 26 inches above the floor. This installation height works well with standard as well as comfort height, or handicapped, toilets. Distance From Toilet The other important measurement is that it should be placed eight to 12 inches, on center, from the toilet to the facing wall. Measure from the very front of the toilet bowl. To optimize this measurement, consider the average height of household members and place it eight to 10 inches from the front of the bowl for shorter users and households with kids; place it 10 to 12 inches in front of the bowl for households consisting of taller members. Final Option If you are unable to permanently wall mount or cabinet mount a dispenser within these optimal measurements, consider a free-standing dispenser.

Maybe because of the vertical position, it might be easier to access on the small wall to the right of the toilet by the shower wall??"
