What lighting for a mirror cabinet to choose for the bathroom
Bathroom mirror cabinet lighting – complete guide to choosing
The bathroom is a room where you prepare for the day in the morning and unwind in the evening. And that's why mirror cabinet lighting is one of those details that people underestimate – until the first time they try to apply makeup or shave under the wrong light and the result surprises them unpleasantly. From my own experience, I know that customers focus mainly on dimensions, number of shelves, or cabinet color when buying a mirror cabinet. When asked "what type of lighting do you want there?" the answer usually is: "Well... some white, just let it light up." That's not enough. In this article, I will cover everything related to the topic – from the physical properties of light, through light sources, placement of luminaires, protection against moisture, to specific recommendations for different types of bathrooms.
Why is mirror cabinet lighting important at all?
A standard ceiling light in the bathroom illuminates the space from above. This is ideal for general visibility in the room, but disastrous for work in front of the mirror. Light coming directly from above casts shadows under the nose, under the eyes, under the cheekbones. Result? The face in the mirror looks tired, poorly made-up, and shaving becomes riskier. Professional makeup studios, actors' dressing rooms, and wedding salons have known this for a long time – light must surround the face from the sides and from below, not just from above.
A mirror cabinet with integrated lighting solves this problem elegantly and without interfering with the ceiling light's electrical installation. Light comes directly from the edge of the mirror or from the space around it, thus eliminating unwanted shadows. In addition, such a cabinet contributes to the overall atmosphere of the bathroom – it can be a source of pleasant ambient light during an evening bath, when you don't want to be blinded by the full ceiling light.
Types of lighting in mirror cabinets – overview and comparison
Today, we encounter almost exclusively LED technology on the market, but the way it is integrated into the cabinet is very diverse. Older cabinets used fluorescent or halogen lamps, but these are already rare, and if you come across such a cabinet, I recommend looking for a more modern alternative.
Integrated LED strips around the mirror
The most common type. The LED strip runs around the entire perimeter or at least three sides of the mirror (top and sides). It provides even, soft light without sharp points. Disadvantage: in cheaper models, you may see the LED strip itself through the mirror with all the individual LED points, which looks cheap. Higher quality cabinets use frosted glass or a diffuser that spreads the light into a smooth surface.
Mirror backlight
The LED strip is placed behind the mirror and shines toward the wall. The mirror thus "glows" at the edges, the effect is very aesthetic and modern. The advantage is minimal glare – you only see the light as a halo around the mirror. Disadvantage: for practical purposes (makeup, shaving) this type is less effective, as the intensity of the light falling on the face is lower. Backlight is therefore usually combined with front lighting.
Top lighting
An LED panel or strip is placed only in the top part of the cabinet. A compromise between affordability and functionality. It is sufficient for simple daily use, but not enough for more demanding cosmetic work – shadows under the cheekbones and nose remain.
Side lighting
LED strips on both side edges of the mirror. From the perspective of practical function, the best variant for work in front of the mirror. Unfortunately, less common in the cheaper segment. When we talk about higher-end cabinets, a combination of top and side lighting is standard.
Combined (top + side + backlight)
Premium cabinets offer a combination of multiple types. Front, side, and top LEDs ensure functional face lighting, and backlight adds an atmospheric component. Some models allow these sources to be controlled separately or the intensity of each circuit to be adjusted individually.
Color temperature of light – the most important technical parameter
This is where most people make a mistake and then wonder why their makeup looks completely different outside compared to in front of the mirror at home. Color temperature is expressed in Kelvins (K) and affects how we perceive the colors of objects illuminated by a given light source.
Warm white light (2 700 – 3 000 K)
Yellowish, warm, relaxing. Perfect for the bedroom, living room or bathroom where you want a pleasant atmosphere in the evening. Disadvantage when working in front of a mirror: it warms up skin tones, hides redness, but also distorts the color tone of nail polish, eyeshadows and lipstick. You apply makeup that looks perfect – and when you go outside, it looks completely different.
Neutral white light (3 500 – 4 000 K)
A good compromise. The light is white without a distinct warm or cold tint. For a bathroom where you primarily shave or do basic makeup, this is a reasonable choice. Most mirror cabinets with fixed settings have exactly this spectrum.
Cool white / daylight (5 000 – 6 500 K)
Bluish, bright, similar to daylight. The most accurate representation of skin colors. Ideal for professional makeup – you will see all imperfections, but you will also be sure that what you see is what others will see. Disadvantage: in the bathroom, it can feel cold, sterile, especially in the evening.
Adjustable color temperature (CCT)
A solution for perfectionists and people who use the bathroom for various purposes. Mirror cabinets with CCT function allow switching or smoothly changing the color temperature – in the morning you set 5 000 K for precise makeup, in the evening during a bath you switch to 2 700 K for relaxation. This feature is available in the mid and higher price segments.
Color Rendering Index (CRI) – a parameter most people ignore
CRI (Color Rendering Index) or Ra is a number from 0 to 100 that indicates how accurate the colors of illuminated objects are in comparison to natural daylight (CRI 100). The higher the value, the better. For bathroom lighting in front of a mirror, there is a simple rule:
- CRI below 80: Unacceptable for any cosmetic work. Colors are distorted, skin can appear grayish or sickly.
- CRI 80–89: Standard sufficient for a regular bathroom, shaving, basic care.
- CRI 90–95: Excellent. Skin tones, nail polish, eye shadows will match reality. I recommend this as a minimum for mirror cabinets where you do makeup.
- CRI 95–98: Professional level. If you are seriously into makeup or share the bathroom with several people with different needs, this is ideal.
In practice, cheaper LED cabinets (under 80–100 €) have a CRI around 80. The mid-range (100–200 €) is around 85–90. Premium models above 200 € offer CRI 90+. Look for the abbreviation CRI or Ra on the label or in the specifications.
Protection against moisture – IP classes for the bathroom
The bathroom is legally divided (STN EN 60598, or the European standard IEC 60364-7-701) into zones according to the distance from the water source. These zones determine the minimum required IP protection for electrical devices.
- Zone 0 – inside the bathtub or shower. Irrelevant for a home bathroom.
- Zone 1 – the space directly above the bathtub or shower up to a height of 2.25 m. Minimum IP44.
- Zone 2 – 60 cm around Zone 1 horizontally and the space above it up to 3 m. Minimum IP44.
- Outside the zones – the rest of the bathroom. IP20 is technically sufficient, but IP44 is recommended for safety and longevity.
A mirror cabinet with lighting is usually mounted above the sink, so outside the direct water zones. Despite that, steam and condensation occur in the bathroom. Practical recommendation: choose cabinets with at least IP44. If the bathroom is small or the cabinet is close to the shower area, consider IP54 or IP65. On the label, IP44 means: 4 = protection against solid particles larger than 1 mm, 4 = protection against splashing water from any direction.
Note from practice: I have seen cabinets with IP20 in bathrooms that worked for years without problems. But when they failed, it was always due to moisture. Saving money on the IP class is a short-sighted decision.
Power consumption, brightness and energy class
LED technology is energy efficient, but there are still differences. For a mirror cabinet, the following parameters are relevant:
Power consumption and brightness
Cabinets with an LED strip around the mirror usually have a power consumption of 8–30 W. The light output ranges from 400 to 2 500 lumens. For orientation: a standard E27 LED bulb with 10 W emits about 800 lm. A 60 cm wide cabinet with side and top LED strips with a power consumption of 16 W and a light output of 1 200 lm is sufficient as the main light source in front of the mirror for a standard bathroom (5–8 m²).
For a large bathroom or a cabinet that is also to serve as the main lighting for the room, look for a power consumption of 20+ W and a light output above 1 500 lm. For a compact bathroom where the ceiling light is still in use, 8–12 W in the cabinet is sufficient.
Dimmability
Some cabinets allow dimming via a touch sensor or remote control. This is a practical feature: full brightness in the morning for precise makeup, 20–30 % in the evening for gentle lighting while brushing your teeth. Dimmable cabinets either have their own switch on the cabinet body or must be connected via a dimmable circuit breaker in the distribution board (ask your electrician in advance).
LED lifespan
Quality LEDs integrated into cabinets have a declared lifespan of 30 000–50 000 hours. At 2 hours of daily use, this means 40–68 years – so LEDs should last longer than the cabinet itself. The problem is often not the LED chip itself, but the control electronics (driver, touch sensor). Pay attention to the warranty – the cabinet usually has 2 years, but the LED module should have at least the same certificate.
Light control – switches, touch panels, motion sensors
The way the lighting of the mirror cabinet is controlled affects the comfort of everyday use. There are several common variants:
Switch on the cabinet body
Classic. Simple, reliable, cheap. Disadvantage: you have to reach the cabinet, which is less pleasant with wet hands, and if the cabinet is improperly placed, it may be hard to reach. Some models have a switch on the side, others on the bottom edge.
Touch sensor on the mirror
It is enough to touch the mirror surface at the marked place. Elegant, modern. It may be sensitive to condensation – some cheaper models "trigger themselves" when there is strong steam. Quality models solve this with a capacitive sensor, which distinguishes a finger touch from a water droplet.
Infrared motion sensor (PIR)
The cabinet lights up when you enter the bathroom and turns off after a set time. Practical, energy-saving. Problem: the sensor may activate the light even when you just pass by, or on the contrary, it may turn off during a calm activity (e.g., reading while sitting in the bathtub).
Remote control or app
Premium models with the possibility to adjust the color temperature and brightness via a remote control or smartphone app (Bluetooth/Wi-Fi). The most comfortable, but also the most expensive and technically complex option. For a standard bathroom it is mostly unnecessary, but for a renovated bathroom with an intelligent electrical installation (smart home) it makes sense.
Power supply and electrical installation – what to know before buying
Mirror cabinets with lighting are powered from the 230 V grid. This means that there must be an electrical socket or a direct cable connected to the electrical installation behind the cabinet. This is the point where the most complications arise during renovations:
- If there is no socket behind the mirror, an electrician must install a new one. This requires an intervention into the wall and preparation of a cover or a special frame.
- Cabinets with an integrated plug are more convenient for installation, but the plug must not be visible in zone 1 and 2.
- Direct connection to the installation (without a plug, via a terminal block) is a more professional option, looks cleaner, but requires a certified electrician.
- Some cabinets have a built-in 12V transformer for the LED strip – this does not change the requirement for a 230V supply, but the LED strip itself is safer when in contact with condensation.
Practical tip: Before buying a cabinet, measure exactly where the electrical box or socket is in the wall. The cabinet must cover it, otherwise you will have problems with appearance and safety. More about the technical side of installation can also be found in the article Mounting a bathroom cabinet and sink cabinet step by step.
Cabinet dimensions and light placement – practical proportions
The width of the mirror cabinet directly affects the quality of face lighting. A narrow cabinet (40 cm) with side lighting has the lights too close to each other – the light meets in the center and instead of even coverage, it creates one bright spot. The ideal width for side LED lighting when working in front of the mirror is at least 60 cm, optimally 70–80 cm.
The height of the cabinet affects how deep the light illuminates the area of the chin and neck. A cabinet of height 60–70 cm with side LED strips covers the entire face including the chin. A lower cabinet (40–50 cm) with side lighting illuminates only the upper part of the face.
Recommended mounting heights for good lighting comfort (measured from the floor to the lower edge of the cabinet):
- Standard mounting for adults: 155–165 cm to the top edge of the mirror, so the lower edge of a 70 cm high cabinet is at about 85–95 cm.
- For family bathrooms shared with children: lower mounting at 80 cm from the floor to the lower edge.
- For standing or combined units with a sink (bathroom furniture with an integrated cabinet): the height is determined by the assembled height of the cabinet.

Special features – what modern cabinets offer additionally
The current market of mirror cabinets goes well beyond the scope of "lights up or doesn't light up". Here is an overview of features that you can find in premium models and that can be truly useful in practice (not just a marketing gimmick):
Heated mirror surface (anti-fog)
An electric heating film glued behind the mirror prevents fogging during showering. It works by keeping the mirror surface slightly above the dew point. In practice, you will appreciate it in those moments when after a hot shower you want to look in the mirror and it is all steamed up. The heating power is usually 20–40 W extra. The function is switched on with a separate switch or automatically with the lighting.
Clock and thermometer
A LED display integrated into the mirror or cabinet shows the time or temperature. Practical in the morning when you want to orient yourself in time without a phone. Not all models are accurate – cheaper ones tend to lag.
USB charging
Built-in USB or USB-C port directly on the cabinet body. Practical for charging electric toothbrushes, shavers or smartphones. In the bathroom it is safer than using an extension cord.
Dual mirror (cosmetic magnifier)
Some cabinets have a mirror with 3x or 5x magnification on the inside of the doors. Practical for applying contact lenses, shaping eyebrows or more detailed work. It is not part of the lighting, but increases the functionality of the cabinet.
Choosing by the size and type of bathroom – practical scenarios
Small bathroom up to 4 m² with a combined bath and shower
In such a space, the ceiling light is either weak or dazzling, rarely optimal. A mirror cabinet with integrated lighting serves a dual function here – storage space and mirror lighting. I recommend a model 60 cm wide, 60–70 cm high, with side and top LED strips, color temperature 4 000 K, CRI 85+, IP44. Dimming is a pleasant bonus, but not a necessity. Make sure the cabinet covers the electrical box in the wall. More about choosing furniture for a small space in the article What dimensions of bathroom furniture are suitable for a small bathroom.
Medium-sized bathroom 5–8 m² with a shower corner
There is more space here and there is usually also a ceiling light. A mirror cabinet with lighting complements the overall lighting and primarily serves at the mirror. You can afford a larger model – 70–80 cm wide, with adjustable color temperature (CCT), CRI 90+, backlight for an aesthetic effect. IP44 is sufficient if the cabinet is not closer than 60 cm to the shower. On combining furniture with tiles and the shower corner, read the article How to combine bathroom furniture with a shower corner and tiles.
Double sink bathroom or "couple's bathroom"
Two sinks, two people simultaneously in the morning. Here, either one large cabinet (100–120 cm) with LED lighting all around is ideal, or two separate cabinets side by side. The second option is more practical – each person has their own storage space and their own light. Prerequisite: the electrical installation must account for two power points.
Children's bathroom or family bathroom
The cabinet must be installed lower (bottom edge 70–80 cm from the floor), so that children can see into the mirror. Lighting without sharp points – prefer diffusers, not visible LED strips. Touch sensors are not ideal, as children "test" them. A simple switch is more reliable.
Most common mistakes when choosing mirror cabinet lighting
- Choosing by price, not parameters: A cheap cabinet with CRI 70 and a single-color LED strip will work, but the lighting will be poor. The price difference between an average and a good model is usually 30–50 €.
- Ignoring the IP class: In the bathroom, there is no other option than IP44+. Cabinets without IP markings or with IP20 do not belong in the bathroom, regardless of what the seller says.
- Wrong color temperature: Buying a 2 700 K cabinet for makeup is a classic mistake. If you are unsure, choose a model with adjustable CCT.
- Neglecting electrical preparation: The cabinet arrived, but there is no power supply behind the wall. The electrician comes, and again drilling into the tiles. Always resolve the electrical installation before buying the cabinet, not after it.
- Choosing a too small cabinet for a larger space: A 40 cm cabinet in an 80 cm sink looks absurd and the face lighting will be insufficient.
- Purchasing without a warranty on the LED module: Some sellers guarantee only the cabinet structure, not the electronics. Always check what the warranty covers.
Frequently asked questions (FAQ)
What LED color temperature is best for a bathroom mirror if I do makeup?
For makeup, the ideal color temperature is in the range of 4 500–5 000 K – that is, neutral to slightly cool white, close to daylight. At this temperature, skin tones, nail polish, and cosmetic colors are displayed most accurately. Avoid warm white (2 700–3 000 K), which warms up the tones and hides imperfections – that sounds tempting, but you will look different outside. If the cabinet offers adjustable CCT, choose 4 000–5 000 K for regular use and 5 000–6 500 K for detailed work.
Is it necessary to have an electrician for the mirror cabinet, or can I wire it myself?
It depends on the wiring method. If the cabinet has a plug and there is an outlet behind the mirror (230V, in the bathroom it must be IP44 protected), you can wire it yourself. If a new outlet or power supply needs to be installed, it is a change to the fixed installation, which requires a certified electrician (inspector). In the bathroom, stricter safety standards apply than elsewhere in the apartment – don't improvise with extension cords or unprotected outlets.
What is more advantageous – an LED strip around the mirror or backlight (underlighting)?
For practical functional lighting (shaving, makeup, visual inspection), the LED strip directly on the front edge of the mirror is clearly better – side or a combination of side and top. Backlight (underlighting) is mainly an aesthetic feature that gives a pleasant visual effect of a glowing mirror, but it is weaker for work in front of it. The best premium models combine both: front LED for functional use and backlight for evening ambiance. If you have a budget for one type, prioritize the front side LED.
Can I install a mirror cabinet with LED lighting myself, without any mounting experience?
Mounting the cabinet itself on the wall is not difficult – most models are attached using metal brackets or a strip included in the packaging. You need a drill, wall anchors suitable for the wall material (concrete, drywall, tiles), and a spirit level. Critically important is using the correct anchors for tiles to prevent the wall from cracking. Much more problematic is the electrical part – see the previous question. A detailed installation procedure is available in the article Installation of a bathroom cabinet and sink cabinet step by step.
How long do LEDs in a mirror cabinet last and can they be replaced?
Quality LED strips and modules have a declared lifespan of 30 000–50 000 hours. At 2 hours of daily use, this is 40–68 years – longer than you plan to own the cabinet. In practice, the driver (power supply) or touch sensor is more likely to fail. Replacing the LED module depends on the cabinet design: some models have standardized LED strips (commonly available), others have proprietary modules (only original spare parts). Before purchase, ask the seller if spare parts are available and at what price.
Is it worth paying extra for a cabinet with adjustable color temperature and dimming?
It depends on your lifestyle and the number of people using the bathroom. For a single household with clearly defined needs (just morning shower and shaving), adjustable CCT is a luxury, not a necessity. For a family, where one member needs daylight for makeup and another wants warm relaxing light in the evening, or for people working shifts (active morning routines both in the morning and in the evening), the investment in CCT and dimming is definitely worth it. The price difference compared to a cabinet with fixed temperature is usually 40–80 €.
Conclusion – how to make the right decision
Choosing mirror cabinet lighting is a combination of technical parameters (CRI, color temperature, IP class, power consumption) and practical logic (who and for what uses the bathroom, what the space layout is, what you have behind the wall). A universal recommendation for most households is: side and top LED lighting, color temperature 4 000 K, CRI at least 85, IP44, cabinet width at least 60 cm. If you invest a bit more, CCT and dimming will significantly improve your bathroom experience.
