The precise measurement for how high above the shower floor these components should be placed depends on the specific building codes and accessibility standards in a given jurisdiction. However, a commonly used guideline is that the controls, faucets, and shower spray unit should be located between 38 and 48 inches above the shower floor.
This range ensures that the controls and faucets are accessible to individuals using the shower, especially those with mobility limitations, while also considering the convenience of reach and use.
