Did you know that your bathroom has specific lighting zones? Lighting a bathroom is not the same as lighting any other room in your house. The unique conditions of high moisture and steam require specific lighting regulations to ensure your safety and the longevity of the lighting itself. In this guide, we will walk you through the different bathroom lighting zones and help you choose the right lighting for your bathroom space.

Understanding Bathroom Light Zones

The UK's national standard for safe electrical installation, known as the IET wiring regulations, defines four hazard zones for bathroom lighting. Each zone represents the proximity of light fittings to water sources, determining the type of lighting that can be safely used.

For example, lights placed directly above the shower stall are exposed to higher levels of steam and moisture, requiring water-resistant fittings. Let's explore the different bathroom lighting zones and the recommended lighting for each zone.

The Bathroom Lighting Zones

• Zone 0: This zone refers to lighting directly inside the bath or shower.
• Zone 1: Lighting above the bath or shower, up to 2.25 meters from the floor.
• Zone 2: Lighting placed on the sides of the bath, shower, or wash basin, up to 0.6 meters outside the perimeter of the water sources and up to 2.25 meters from the floor.
• Outside Zones: Any areas outside the defined lighting zones.

Understanding IP Ratings

The suitability of bathroom lighting is determined by its IP (Ingress Protection) rating. The IP rating indicates how effectively the light is protected from liquids or solid objects, allowing you to determine where you can safely install the light in your bathroom.

The IP rating is denoted by the initials 'IP' followed by two digits. The second digit indicates the level of water resistance. The higher the digit, the more water-resistant the light is.

Here is a breakdown of IP rating digits and the corresponding level of water protection according to current bathroom light regulations:

• IP0X: Not protected.
• IPX1: Protected against dripping water.
• IPX2: Protected against dripping water when tilted at 15 degrees.
• IPX3: Protected against spraying water.
• IPX4: Protected against splashing water.
• IPX5: Protected against water jets.
• IPX6: Protected against powerful water jets.
• IPX7: Protected against immersion up to a depth of 1 meter.
• IPX8: Protected against immersion beyond 1 meter.

To simplify your decision-making process, here are the recommended IP ratings for each bathroom lighting zone:

• Zone 0: IP67.
• Zone 1: IP45 or higher.
• Zone 2: IP44.
• Outside Zones: IP20 (IP44 recommended).
