How to Light a Bathroom With No Natural Light

Bathrooms are a high activity place that requires plenty of illumination for safe usage. Add in the moisture and risk of slips and falls, and visibility becomes even more important. If you do not have natural bathroom lighting, it's important to provide ample artificial illumination.

Without windows, visibility will automatically be lower. Shadows will be stronger. This is especially troublesome if you need to apply makeup, as you will have to squint to see through the shadows.

You can avoid both of these issues by ensuring the entire thing is well-lit. Installing task lighting for bathrooms, such as overhead shower lights and LED bathroom mirror lights, can help avoid this.

For many, bathrooms are a place of comfort and relaxation after a long day at work. Without good bathroom lighting, they can feel cold and uninviting instead. Install warm, diffused lighting to give it a spa-like feel.

 Why the Use of Mirrors Is Vital to a Bathroom With No Natural Light 

When you're considering how to light a bathroom with no windows, you should think beyond the light fixtures themselves. One of the biggest cheat codes of lighting for windowless bathrooms is to take advantage of mirrors.

Mirrors are key for enhancing the distribution of light. The light bounces off the reflective glass and disperses it more completely through the space. When you position the mirrors strategically opposite the light source, you can bounce light throughout the room more effectively.

Rooms that have no natural light tend to feel smaller and more cramped as well. A mirror can give the illusion of space and make the bathroom feel larger than it really is. Brightening the room and making it seem bigger will make your bathroom overall more comfortable to use.
 

How to Use Layered Lighting in a Bathroom With No Windows 

One of the best bathroom lighting tips anyone can give you would be to layer your LED bathroom lights. Layering the lights involves adding ambient, task and accent lighting to the room for a well-balanced look.
 

Ambient Lighting

Ambient light is the main layer of illumination in the space. It provides the foundation upon which other lights can build and supplement. Modern bathroom lighting designs often use recessed ceiling lights for the ambient light layer. You can also use surface mounted downlights or pendant lights depending on the style of your bathroom. 

Task Lighting

An important element of your layered bathroom lighting, task lights provide focused illumination for various activities. Task lights come in different forms, like shower lights and vanity light fittings. These are designed to help you more clearly see when grooming or bathing. Think in terms of indoor wall sconces and overhead bathroom lighting fixtures. 

Accent Lighting

Accent lighting for dark bathrooms not only eliminates shadows in high or recessed spaces. It can also serve as mood lighting for bathrooms by providing gentle, indirect lighting. Accent lights can be installed in alcoves and niches in the bathroom, or the plinth area below the sink cabinets. These provide a good opportunity to incorporate dimmable lights as well.

What Are LED Colour Temperatures and What Is the Best One to Use in a Windowless Bathroom? 

Colour temperatures, also sometimes referred to as CCT, is a way to discuss the warmth or coolness of a light. The temperatures exist on a scale between 1000K and 10,000K, with warmer colours at the bottom and cooler lights at the top.

Colour temperature is important in any room of the house, but especially in dark, windowless bathrooms. This is because the artificial light is the only source setting the mood, and colour temperatures dictate that mood.

In bathrooms that need a more relaxing feel, warm lighting is preferred. Choosing light colours between 3000K and 3300K provides soft, warm lighting that still gives plenty of visibility. This temperature is ideal for spa-like bathrooms especially.

If you prefer to instead mimic the appearance of natural daylight, you'll want to shoot for the range of 3500K to 4000K. This neutral white colour temperature more closely resembles natural sunlight and can make the bathroom feel airier and more open.

Regardless of the light you choose, it is a good idea to choose bulbs with a high CRI, especially near mirrors. CRI, or colour rendering index, indicates how accurately a light shows the colours of the items it shines upon.

When putting on makeup or getting dressed, you want to be sure that what you see in the mirror will be what others see in the light of day. High CRI lights help you do this.

Whether you opt for cool or warm lights, just be sure that you are only choosing one or the other. Having cool and warm lights both in the bathroom can cause abrasive clashing and may strain the eyes.
 

What Are the Common Mistakes You Can Make When Lighting a Windowless Bathroom? 

Indoor LED lighting for bathrooms with no windows can be tricky business, but it is possible to accomplish with a little planning beforehand. Get acquainted with some of the most common mistakes people make so you can avoid them entirely. 

  • INSUFFICIENT LIGHTING. The biggest mistake you can make is not including enough illumination in the bathroom. Already it is so dark because there is no natural light; do not skimp on adding in the supplemental lighting. Be sure you are not relying on a single fixture. Instead, incorporate different types of bathroom lights and layer them together. 


  • WRONG COLOUR TEMPERATURE. Choosing the wrong colour temperature can negatively affect the mood and atmosphere of the space. Choose the colour temperature that best suits the aesthetic you are going for. Warmer lights are better for relaxing, spa-like bathrooms. Cooler lights work better if you want something that mimics natural light. 


  • FORGETTING TASK LIGHTS. Since bathrooms are such a high-activity area, task lights are a must. You can include them in creative ways, such as with interior wall lamps for bathrooms positioned on either side of a vanity. You can also install overhead shower lighting to make bathing and showering safer and easier. 


  • IMPROPER PLACEMENT. Neglecting to properly place your bathroom lights can result in unsatisfactory results. For example, LED ceiling lights for bathrooms should be evenly spaced across the room, and kept away from the walls to avoid shadows. Task lights, on the other hand, should sit around eye level at the mirror to avoid glare. 


  • USING THE WRONG BULBS. By not choosing LED lights, you are robbing yourself of the best possible light quality. Skip out on incandescent and halogen bulbs and use high quality LEDs instead.

Why LED Lighting Is the Best Option for a Bathroom With No Natural Light 

Bathroom lighting trends change over time, but one truth remains the same: LED bulbs are superior. LED lights bring with them a number of benefits that traditional bulbs do not.

Besides being energy efficient bathroom lighting, LED illumination is simply generally superior. It offers consistent, bright lighting that does not flicker or fade. This is important for such a task-heavy space as the bathroom. Unlike traditional bulbs, they also immediately turn on as soon as you flip the switch, so you won't have to wait for them to achieve full brightness.

LED lights also offer directional lighting, letting you decide exactly where you want the light to shine. This can help eliminate the dark corners that a lack of natural light can cause. Such flexibility allows you to avoid a lot of the issues that windowless bathrooms can cause.

Since LED lights do not generate noticeable heat the way halogen bulbs do, they are better for smaller, darker bathrooms. You won't have to worry about the light getting too hot or causing the bathroom to feel uncomfortably warm when running them for long periods of time.
 

How to Make a Smaller Windowless Bathroom Seem Larger With Lighting 

The best bathroom lighting ideas for smaller bathrooms are going to be the ones that make it seem brighter and more spacious. There are many tricks you can employ to make the most out of your small, windowless bathrooms, including:
 

  • LAYERING LIGHTS. By ensuring you have included all of the layers of light, you are likely to avoid having any dark spots. Eliminating shadows and lighting up all of the dark recesses will make the bathroom seem larger and more spacious. Simultaneously, it will create visual depth. 


  • CREATE A SENSE OF HEIGHT. Make the most out of the vertical space with wall mounted uplighters. By shining light up the wall, you can naturally lead the eye upwards. Doing so can create the illusion of more height, therefore making the overall room seem larger. 


  • INCLUDE MIRRORS. Adding in mirrors can help bounce what light you have around the room. Reflecting the illumination around the room can make it seem larger, while the actual visuals of the reflective glass can trick the eye into thinking there is more space as well. 


  • USE WALL MOUNTED LIGHTS. In smaller bathrooms, saving space is critical. One way to do so is to use internal wall lights. This eliminates the need to have bulky overhead lights hanging down which could clutter up the space. Instead, you can take advantage of all of that empty wall space and turn it into functional lighting zones.

Advice on Colour Palette Choices to Enhance the Lighting in a Windowless Bathroom 

Colour plays a big role in the perception of a room, especially when it comes to its perceived size and brightness. For this reason, it is important to take a moment to thoughtfully consider what colours you will use to enhance your windowless bathroom.

A general recommendation is to go for light, neutral hues. Lighter colours reflect light better than darker ones, which only absorbs it. Colours such as off white, beige, grey and pastels can help move light around the room while making it feel more open.

Similarly, opting for earthy colours and materials can help give the room a more "natural" feel. When you pair them with daylight-like lighting in the 4000K range, it can make your bathroom feel like an extension of the outdoors.

You can also opt for reflective, glossy finishes instead of matte ones. Glossy tiles, metallic light fixtures, mirrored surfaces and glass shades promote the movement of light throughout the room. This helps you make the most of the light sources you have.
