Badezimmerbereiche

Badezimmerbereiche, commonly translated as bathroom zones, refers to the functional divisions within a bathroom. These zones are conceptualized to ensure safety and hygiene, particularly concerning electrical installations and water. The primary zones are typically defined by the proximity of electrical outlets and appliances to water sources.

Zone 0 is the area directly inside the bathtub or shower tray. Electrical installations in this zone are strictly prohibited unless they are extra-low voltage systems (SELV) with a voltage not exceeding 12V AC or 30V DC, and the transformer is located outside of zones 0, 1, and 2.

Zone 1 extends from the top edge of the bathtub or shower tray to a height of 2.25 meters. In this zone, SELV systems are permitted, provided they are suitable for the environment. Fixed water heaters and certain light fittings may also be permissible if designed for this zone.

Zone 2 is the area extending 60 centimeters horizontally from the edge of Zone 1 and up to a height of 2.25 meters. This zone allows for more electrical equipment than Zone 1, still generally requiring SELV or appliances with a higher IP rating (Ingress Protection) for protection against water spray.

Beyond Zone 2 is considered the general area, where standard electrical installations are usually permitted, although it is still advisable to consider the potential for water splashes. The specific regulations and definitions for these zones can vary by region and national electrical codes. Understanding these Badezimmerbereiche is crucial for safe bathroom design and renovation, especially when installing any electrical fixtures or appliances.
