Our Definitive Bathroom Lighting Guide: Practical Advice, Safety Tips, and More

So, you're planning a brand-new bathroom, and you've got everything down pat – from the tiles to the fixtures, the vanity, and the tapware. All that's left to tie it all together is the lighting. And we know it may seem daunting, with so many options to consider and countless dos and don'ts to wrap your head around. But don't worry; this guide will outline everything you need to know — from practical tips and safety musts to bathroom lighting design ideas that prove prioritising functionality doesn’t mean sacrificing style.

The Role of Lighting in a Bathroom

Lighting in a bathroom plays a far more important role in your bathroom design than you might think. From the obvious—helping you see in the dark and providing the perfect light for tasks like shaving or applying makeup—lighting also plays a significant role in setting the ambience and enhancing the feel of your space. The right lighting design can completely transform how your bathroom looks and feels, making it feel lighter, brighter, and more spacious than it is. Put simply, great bathroom lighting isn’t just practical—it’s a design element in its own right.

Types of Lighting

When considering lighting for your bathroom, the first thing you want to think about is purpose. Will you need bright light for tasks like showering and applying makeup, or a softer, more relaxing light for bath time? Perhaps both? And that's okay; layered bathroom lighting allows you to combine different light types to create a space that's both functional and inviting—we'll explore this in more depth a bit later.

Taking time to think about how you use your bathroom and the mood you want to create will help you decide what type of lighting best suits your overall needs. To make it easier, lighting can be broken down into four main categories:

• Ambient - This is the general lighting that provides overall illumination for the entire space.
  
• Task - Bathroom task lighting is focused lighting that helps you perform specific activities, such as shaving, brushing your teeth, or applying makeup.
  
• Accent - Accent lighting is used to highlight features or design elements in your bathroom, such as textured walls, artwork, or shelving.
  
• Decorative - More stylish than it is functional, decorative lighting adds personality and flair to your space, making it a design feature in its own right.

Space Specific Considerations (Small vs. Large Bathrooms)

When it comes to bathroom lighting, size and type really do matter—but not in the way you might think. Whether you’re working with a compact powder room or a spacious master suite, the key is choosing lighting that suits the scale and function of the space.

Lighting a Small Bathroom

Lighting must work hard in smaller bathrooms without taking up too much space. The goal is to create the illusion of space while still providing enough light for everyday tasks. In a small bathroom, we tend to worry only about ambient lighting, as there isn't much space for anything else. Opt for wall-mounted fixtures or recessed lighting instead of large, low-hanging lights that take up space and disrupt the flow of the room.

Lighting a Large Bathroom

When you have a larger bathroom, you have more space to work with, but that also means more planning is needed to ensure everything is adequately lit. Think of your bathroom in terms of different zones and layer your lighting to suit the function of each area. Try multiple sources of ambient lighting to brighten up the overall space and maybe some task and accent lighting around your mirrors and fixture features to add a little warmth and personality.

Modern Trends in Bathroom Lighting

Bathroom lighting has evolved from a purely functional necessity into a key element of interior design. These days, it’s all about creating a space that feels both beautiful and personal—somewhere you can get ready in the morning and wind down in the evening. Here are four standout trends that are transforming bathrooms all across Australia:

• Statement Lighting - Bold, decorative lighting is trending as homeowners turn bathrooms into more stylish, design-forward spaces. Statement pendants, chandeliers, and sconces are being used to turn bathrooms into more spa-like spaces.
  
• Using Natural & Sustainable Materials - Sustainability continues to shape interior trends, and bathroom lighting is no exception. Fixtures made from natural materials, such as bamboo and recycled wood, are gaining popularity for their organic look and minimal environmental impact.
  
• Layered Lighting - Layered bathroom lighting is having a moment—and it’s easy to see why. It adds warmth, depth, and that dreamy, spa-like vibe we’re all craving in our bathrooms right now. With layered lighting, you can easily switch from bright light to calming glow, perfect for turning your functional space into a more relaxing retreat.
  
• Smart Lighting - As smart homes become the norm, smart bathroom lighting is gaining popularity. From motion sensors to app control and custom brightness settings, this trend is all about making life easier and more energy-efficient

Lighting Safety Considerations

When you're thinking about renovating your bathroom, one of the last things on your mind is probably the technical and safety regulations. That's okay—these are for your builder and electrician to know—but it wouldn't hurt for you to be aware as well!

IP Ratings

IP stands for Ingress Protection, and it’s a handy rating system that indicates how well an electrical device, such as a light fixture, can withstand elements like water, dust, and moisture. The IP rating consists of two digits following the 'IP' label. The first digit represents how well the device is protected against particles such as dust, with a range from 0 to 6, while the second digit indicates its resistance to water, with a range from 0 to 8. Essentially, the higher the numbers, the greater the protection from both dust and water!

Bathroom Zones

Bathrooms are divided into zones based on how close they are to various water sources, such as the bath, shower, or sink. These zones are helpful for many reasons, one of which is to help people understand what electrical devices, like lighting, can and cannot be used near different water sources. Below, we'll discuss each zone and the minimum IP rating required for each.

• Zone 0 - The areas in your bathroom that collect water, such as inside your bath, shower, or vanity/basin. Minimum IP - IP67.
  
• Zone 1 - The areas directly above the bath or shower, to a height of 2.25m, where water splashes or steam can reach. Minimum IP - IPX4 (typically IP44 OR IP65).
  
• Zone 2 - The areas within 60cm of your bath, shower or sink (Zone 1) to a height of 2.25m, where water may splash. Minimum IP - IPX4 (typically IP44 OR IP65).
  
• Zone 3: The area outside of zones 0-2. There is no minimum IP rating for this zone.

Lumens & Brightness Recommendations

Although there are no enforced regulations when it comes to lumens and brightness requirements in bathrooms, there are some general guidelines that are helpful to understand. Why? Well, because—outside of the kitchen—the bathroom needs the brightest lights in the home, meaning you’ll want lighting that’s strong enough for practical tasks, but still soft enough to create a relaxing atmosphere.

Our general rule of thumb for bathroom lighting is to aim for around 400 lumens per square metre, which is usually enough to ensure the space is well-lit for everyday use. For bathroom task lighting, such as around the mirror or vanity, 1200 to 1600 lumens is ideal to provide the brightness you need for grooming, shaving, or applying makeup without casting harsh shadows.

Bathroom Colour Temperature Guidelines

If you’ve ever bought the wrong temperature bulb by mistake, you’ll know just how much colour temperature can impact the look and feel of a space, especially in the bathroom. Bulb colour temperature is measured in Kelvin (K).

A lower Kelvin value indicates a warmer, more yellow-toned light, while a higher Kelvin value indicates a whiter, cooler light. As a general rule of thumb, for bathrooms, you want to avoid higher Kelvins as this can make the space feel cold and overly clinical. Bulbs between 2500 and 3000K are usually more appropriate in bathrooms as they provide sufficient brightness without feeling too clinical.

Practical Bathroom Lighting Tips & What to Avoid

Now that you're getting the hang of bathroom lighting, let's make sure you've got all the angles covered with some friendly advice! Here’s a quick rundown of dos and don'ts to help you light up your bathroom in the best way possible.

DO:

• Follow a Layered Approach: Begin by getting your ambient lighting right, then consider task and accent lighting. This step-by-step approach makes it easier to navigate the overwhelming number of lighting options available. It also helps to achieve a balanced, well-lit space that is both functional and aesthetically pleasing.
  
• Prioritise Natural Lighting - Making the most of natural lighting by installing large windows and skylights brings warmth into your bathroom, particularly on sunny days. It also enhances visibility and reduces the need for artificial lighting, helping you save on energy bills.
  
• Consider Dimmable Lighting - Dimmable lighting allows you to customise the brightness level to suit your desired ambience or atmosphere. Because they use less energy when dimmed, dimmable lighting also helps you save on your energy bills.

DON'T:

• Rely on a Single Overhead Light - Having just one overhead light is very limiting in terms of functionality. It often doesn't provide enough illumination for various tasks, and it can create nasty shadows that aren't great when performing tasks like shaving or applying makeup.
  
• Ignore Task Lighting - Adequate task lighting is essential for illuminating specific areas where you need enhanced visibility, such as at the vanity or shower. Layering task lighting with ambient and accent lighting will enhance visibility and reduce shadows. Ignoring it will ultimately result in a less comfortable bathroom experience.
  
• Hang Lighting Too Low - Hanging lighting too low, especially in smaller bathrooms, will make the space feel smaller than it actually is. Hanging lights too low may also obstruct movement and create inconvenient shadows, which disrupts both the flow and function of the space.
