What IP Rating to Choose for Bathroom Lights

Posted by ilker Duymaz on

Bathrooms, with their mix of moisture and electricity, can be challenging areas to navigate when it comes to selecting the right lighting. One of the most crucial considerations is the Ingress Protection (IP) rating. But what exactly is an IP rating, and which one should you select for your bathroom lights? This guide will help clarify your choices.

What IP Rating to Choose for Bathroom Lights

Understanding IP Ratings

An IP rating, consisting of two digits, is an international standard that indicates how well an electrical fixture, like a light, is protected against solid objects (such as dust) and liquids.

  • The first digit indicates the protection against solid objects and ranges from 0 (no protection) to 6 (full protection against dust).
  • The second digit denotes protection against liquids and ranges from 0 (no protection) to 8 (protection against prolonged effects of immersion under pressure)

Choosing the Right IP Rating for Your Bathroom

Bathrooms are divided into different zones based on the likelihood of water contact. Each zone requires lights with a specific IP rating:

  • Zone 0: Inside the bath or shower itself. Lights here need to be low voltage (12V max) and have an IP rating of at least IP67, which means they are waterproof.
  • Zone 1: The area directly above the bath or shower. The lights in this zone should have a minimum rating of IP44, though IP65 (fully jet-proof) is often recommended for added protection.
  • Zone 2: An area stretching 0.6m outside the perimeter of the bath and to a height of 2.25m from the floor. In this zone, an IP rating of at least IP44 is required.
  • Outside zones: This encompasses any area outside of Zones 0, 1, and 2. There is no specific IP requirement here, but IP20 or higher is advisable.
