Recommendations: The Standards provide advisory (non-mandatory) guidance on
the water closet height and centerline and the height of grab bars and toilet paper
dispensers according to three age groups (above). The chosen specifications should
correspond to the age of the primary user group. The specifications of one age group
should be applied consistently in the installation of a water closet and related elements.
