Choosing bathroom lighting is about more than style. Because bathrooms are exposed to moisture and splashes, it is important to choose fittings that are suitable for their location.
Bathroom lighting regulations set out different zones, each with specific requirements for electrical safety and water protection. Here’s what you need to know before choosing your bathroom lights.
What are bathroom lighting zones?
Bathroom zones are defined in Section 701 of BS 7671, the IET Wiring Regulations. They help determine which electrical fittings are suitable for different areas around a bath or shower.
Zone 0: Inside the bath or shower
Zone 0 covers the inside of a bath or shower tray. Lighting installed here generally requires an IPX7 rating for protection against temporary immersion, as well as a suitable SELV supply at the permitted voltage.
Zone 1: Above the bath or shower
Zone 1 generally extends up to 2.25 metres above the floor above a bath or shower. Fittings typically require at least IPX4 protection against splashing water, or IPX5 where water jets are likely to be used for cleaning.
Zone 2: Around the bath or shower
Zone 2 extends 0.6 metres beyond Zone 1. Fittings generally require at least IPX4 protection, increasing to IPX5 where water jets are likely to be used for cleaning.
Outside the zones
Areas outside the defined zones do not have a specific minimum IP rating under Section 701 alone. However, fittings must still be suitable for the room's moisture levels and intended location.
What is an IP rating?
An IP (Ingress Protection) rating indicates how well a fitting is protected against solid objects and water.
Common bathroom lighting ratings include:
-IP44: Protection against solid objects of 1mm or larger and splashing water.
-IP65: Dust-tight protection and protection against water jets.
-IPX7: Protection against temporary immersion in water.
The right rating depends on the fitting's location and the manufacturer's instructions. IP44 is common for bathroom lighting, but it is not suitable for every zone.
For example, the Dar Eneco 2 Light Bathroom Wall Light in Antique Bronze and Natural Alabaster, IP44 combines decorative materials with splash protection, making it an attractive option to consider for a suitable bathroom location.
Important: An IP44 rating does not automatically mean a light is suitable for every bathroom zone. Always check the manufacturer's installation instructions and confirm that the fitting is appropriate for its intended location before installation.
How to choose bathroom lighting
Once you understand the safety requirements, consider how different fittings can work together to create a practical and inviting space.
1. Choose wall lights for atmosphere and task lighting
Wall lights can add character while providing useful illumination beside a bathroom mirror or basin. For a softer, contemporary look, consider the Franklite Frost Small Bathroom Wall Light. Check its product specifications and installation instructions to confirm its suitability for your intended location.
2. Consider a pendant for decorative impact
Pendant lighting can introduce a focal point and complement the wider interior scheme. The Astro Ottavino Pendant in Polished Chrome offers a sleek, contemporary finish.
Before choosing a bathroom pendant, check its permitted installation location, the ceiling height and the manufacturer's instructions to ensure it is suitable for the intended position.
3. Use ceiling lights for general illumination
A ceiling light provides a foundation for everyday bathroom lighting. The Astro Mashiko Classic 300 Square Bathroom Ceiling Light in Polished Chrome offers a clean-lined design that works well in contemporary interiors.
Combining general ceiling lighting with suitable wall lighting can help create a balanced scheme that is both practical and visually appealing.
Do bathroom lights need to be installed by an electrician?
Bathroom electrical installations must comply with applicable wiring regulations and safety requirements. A qualified electrician can confirm the relevant zones, check fitting suitability and ensure appropriate circuit protection, including RCD protection where required.
Never assume a light is suitable for every bathroom area simply because it is labelled “bathroom lighting”.
Frequently asked questions
Can I use a normal light in a bathroom?
Some fittings may be suitable outside the defined zones, depending on the conditions. Lights in Zones 0, 1 and 2 must meet the requirements for their specific location.
Is IP44 suitable for a bathroom?
IP44 is commonly used where protection against splashing water is required, but it is not suitable for every zone. Zone 0 generally requires IPX7 protection and a suitable SELV supply.
Can I put a pendant light in a bathroom?
Potentially, provided the fitting is designed for the intended environment and installed in a suitable position. Check the manufacturer's instructions and seek advice from a qualified electrician before installation.
