Choose the fitting only after its exact position is known. An IP rating describes protection, but the permitted location is determined by the bathroom zone and local electrical rules.
What the IP code tells you
An IP rating has two digits. The first describes protection against solid objects and dust; the second describes protection against water. In residential lighting, the second digit is often the key bathroom consideration.
IP44 is commonly used where splash protection is required, while IP65 offers stronger water protection. A higher number is not a universal permission to place a fitting anywhere.
Position defines the requirement
Bathrooms are divided into zones around baths, showers, and water outlets. The exact boundaries and permitted equipment depend on the electrical standard applied in the country and the installation.
Share a dimensioned plan with the installer and record the proposed fitting position. Do not choose an IP rating from a room label alone.
Light the face from the sides
Diffuse vertical light on both sides of a mirror gives more even illumination than one strong downlight above the head. Keep the sources shielded from direct view and choose good colour rendering.
Add a separate general or indirect layer so the mirror fittings are not responsible for illuminating the entire bathroom.
Specify and install as one process
Check the complete manufacturer documentation, including IP rating, mounting orientation, driver location, voltage, and whether the product is approved for the intended zone.
Bathroom electrical work should be checked and installed by a qualified professional in accordance with local rules. Product information supports that decision; it does not replace it.
