Anyone looking to install a new light in the bathroom is quickly faced with an important question: can I really use any light in here? The answer is clear: No. Strict safety regulations apply in the bathroom – and anyone who does not know them risks not only a faulty light, but in the worst case, a dangerous electric shock.
Why is the bathroom so special?
The bathroom is the only room in the house where water and electricity come into direct contact. Steam, splashing water, and high humidity make standard interior lights unsuitable – they can short-circuit or even catch fire due to moisture ingress. This is why the German DIN VDE 0100-701 standard clearly specifies which lights can be used where in the bathroom.
The protection zones in the bathroom
The bathroom is divided into four zones – the closer to water, the higher the requirements:
Zone 0 — directly in the bathtub or shower
Water is omnipresent here. Lights must have at least IP67 – meaning protection against temporary immersion. Additionally, only lights with a maximum of 12 volts low voltage may be operated here.
Zone 1 — up to 2.25 m in height around the shower and bathtub
This area is regularly exposed to splashing and jet water. At least IP65 is required – dust-tight and protected against water jets.
Zone 2 — up to 60 cm around Zone 1
Splashing water can occasionally reach this area. At least IP44 is recommended – protected against splashing water from all directions. This also applies to the area around the washbasin.
Zone 3 — the rest of the bathroom
Outside the wet zones, no special protection rating is mandatory. Nevertheless, we recommend at least IP44 – as steam and high humidity will also affect lights further away in the long term.
What happens if I install the wrong light?
Installing a normal IP20 light in the bathroom near the shower is not only dangerous – it is also illegal and will void the warranty. In the event of damage, home contents insurance may refuse to pay if it is proven that an unapproved light was installed.
Who is allowed to install lights in the bathroom?
In Germany, lights in Zone 0 and Zone 1 may only be installed by an electrician. In Zone 2 and Zone 3, lights with the appropriate IP protection rating can also be replaced by a DIY enthusiast – provided that the light is mounted to an existing connection box and no new wiring is laid.
When in doubt, it is better to ask an electrician. The costs are manageable – the risks of incorrect installation are not.
In summary
Clear regulations apply in the bathroom: the closer to water, the higher the IP protection must be. IP67 directly in the shower and tub, IP65 in the immediate vicinity, IP44 in the wider area and around the sink. Those who know and follow these rules are on the safe side – legally and electrically.
