What is the minimum height above the tub floor surface for an exterior window to not require safety glazing?

The correct minimum height above the tub floor surface for an exterior window to not require safety glazing is 60 inches. This requirement is based on building codes intended to prevent the risk of accidental glass injuries, particularly in areas where there is a potential for individuals, especially children, to fall against glass surfaces.

When windows are located near tubs or other wet areas, they must be positioned at a certain height to reduce the risk of contact with the glass. If a window is lower than 60 inches above the tub floor, it is deemed to present a safety hazard; thus, safety glazing is mandated. This precaution helps ensure that if someone were to fall against the window, the risk of injury from shattered glass is minimized.

This height standard helps to ensure that windows are safely positioned in accordance with established safety measures while allowing for natural light and ventilation without compromising safety.
