Lighting Guide: The Bathroom
Designing bathroom lighting requires a careful mix of functionality, safety, and style. The choice of fixtures not only influences the mood but also ensures that the space meets safety standards. With these factors in mind, here’s our guide to achieving the perfect bathroom lighting setup.
Understanding IP Ratings and Zones
Before selecting any light fixtures for your bathroom, it is important to know about IP (Ingress Protection) Ratings and zones.
- Zone 0 is inside the bath or shower itself. Any fitting used in this zone must be low voltage, (max 12v) and be rated at least IP67 which is total immersion proof.
- Zone 1 is the area above the bath or shower to a height of 2.25m from the floor. In this zone a minimum rating of IP45 is required but it is generally accepted that IP65 is to be used. It’s also worth noting that most shower lights are rated at IP65 in any case.
- Zone 2 is 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. In addition it is good practice to consider the area around a wash basin, within a 60cm radius of any tap to be considered as zone 2.
- Outside Areas are any locations around Zones 0, 1, and 2 (subject to specific limits) where water jets are not likely to be used. There are no special IP requirements in this zone, however we suggest that you consider a light with an IP rating of at least IP20+.
Decorative Considerations
Flush pendant lights are a great choice for the bathroom because they spread light evenly without crowding the space, making even smaller bathrooms feel more open. When it comes to the vanity area, task lighting is essential. For instance, wall lights placed on either side of the mirror provide balanced lighting for daily tasks without harsh shadows, doubling as a decorative feature that can complement the room’s design.
Material Selection
When it comes to bathrooms, where humidity levels can be high, it is important to choose materials that can handle moisture and are easy to take care of. Glass is a popular choice for bathroom lighting because it can be easily cleaned and can withstand humidity without losing its brightness. If you go for frosted or opal glass, it softens the light nicely, reducing any harsh glare and giving your bathroom a relaxing, spa-like feel. And if you’re into timeless elegance, brass or bronze fittings are perfect. They look sophisticated and need very little maintenance, keeping your bathroom stylish with minimal effort. We just recommend that you match the metalwork on your light fittings to the bathroom fixtures & accessories.
Choosing the Right Bulb
Each temperature range serves a different purpose, so consider the specific areas and functions within your bathroom to achieve the right balance of ambiance and functionality with your lighting choices.
- Warm lighting (2700K – 3000K): This temperature range creates a cosy, inviting atmosphere, making it ideal for bathrooms where relaxation and winding down are priorities.
- Cool lighting (3500K – 5000K): This temperature range is best for task-oriented areas in the bathroom, such as around mirrors and vanity spaces. It provides a bright, clear light that enhances visibility.
Great bathroom lighting isn’t just about function - it’s about creating a space that feels considered and complete. From mirror lighting for daily routines to statement pieces that add character, the right materials and finishes make all the difference. Thoughtfully chosen designs bring both practicality and personality to the space, ensuring it feels just right, day or night.
