Yes & and no, track lighting is generally not suitable for use in the bathroom. Although track lighting is popular due to its flexibility and modern design, it often does not meet the strict safety requirements that apply to lighting in humid spaces such as the bathroom. Specific IP ratings and waterproofing are of crucial importance in a bathroom environment, and track lighting can usually not provide the necessary protection. However, there are exceptions to the rule, as long as the track lighting remains outside zones 1, 2 and 3 (see image), track lighting can be installed.
Why is track lighting unsuitable for certain areas in the bathroom?
The primary reason that track lighting is not suitable for use in bathrooms is that this lighting and rail often do not have the required IP rating to be safely used in humid spaces. However, outside the shower, bath, or sink zone (and above it), track lighting can be installed.
What is an IP rating?
The IP rating (Ingress Protection) indicates how well an electrical installation is protected against dust and water. The IP rating consists of two digits:
- The first digit indicates the protection against solid objects, such as dust.
- The second digit describes the protection against moisture and water.
Strict requirements apply to lighting in the bathroom, as it is a humid space. Suitable values for bathrooms are shown in bold in the table.
| IP Rating | Meaning | Suitable Spaces |
|---|---|---|
| IP20 | Protected against contact by fingers and large objects | Dry spaces without specific requirements for water or dust tightness, such as living rooms and bedrooms. |
| IP21 | Protected against dripping water and contact by fingers | Indoor spaces with minimal exposure to moisture, such as corridors and halls. |
| IP23 | Protected against splashing water and finger contact | Covered outdoor spaces with limited exposure to weather influences, such as covered terraces. |
| IP44 | Protected against splashing water and contact by small objects | Bathrooms, canopies, balconies, gardens or indoor spaces with an increased risk of moisture. |
| IP54 | Protected against splashing water, dust and finger contact | Covered outdoor spaces with moderate exposure to weather influences, such as terraces. |
| IP65 | Protected against spray water and dust | Outdoor spaces with direct exposure to water jets or severe weather conditions, such as gardens, driveways or washing areas. |
| IP66 | Protected against powerful water jets and dust | Demanding outdoor environments where lighting must withstand harsh weather and water exposure, such as in industry or maritime applications. |
| IP68 | Continuous immersion in water and dust | Underwater lighting, ponds, fountains and other applications where continuous immersion occurs. |
Hazards of Using Lighting in the Wrong Place/Zone in the Bathroom
The use of track lighting or other lighting without the correct IP rating in the bathroom can entail various risks:
- Short Circuits and Electric Shocks: In a humid environment such as the bathroom, the risk of short circuit is greater if the lighting is not properly protected against water.
- Corrosion of Fixtures: Fixtures that are not specifically designed for use in damp spaces can rust and become damaged.
- Loss of Warranty and Insurance: If unsuitable lighting is installed in the bathroom, this can lead to the loss of warranty on the lighting.Additionally, insurance companies may refuse coverage for accidents or damage if it turns out that unsuitable lighting has been installed.
Which lighting is suitable for the bathroom?
Although track lighting is not suitable for every location in the bathroom, there are also lamps that are suitable for the positions in the relevant zones.
Recessed spotlights are a popular choice for bathrooms due to their sleek and minimalist design. They can be placed directly into the ceiling and are often available in versions with a high IP rating (IP44, IP65 or even higher), making them ideal for use in humid spaces. Recessed spotlights with an IP65 rating can even be placed directly above the shower or bath.
In addition to recessed spotlights, there are also special ceiling lights designed for use in damp areas. These lights are often waterproof and provide good general lighting. Choose a lamp with a minimum IP44 rating for zones near the shower or bath.
For an atmospheric addition to the bathroom, there are also wall lights available with a high IP rating. These lights can, for example, be placed along the bathroom walls, outside the wet zones. They can provide warm, indirect lighting while meeting the safety standards.
Tips for safe lighting in the bathroom
- Always check the IP rating: Ensure that every lamp you place in the bathroom has the correct IP rating for the specific zone. Near water sources such as the shower and the bath, a minimum of IP44 is required, but IP65 is even safer.
- Use a qualified electrician: Always have the lighting in the bathroom installed by a qualified electrician. They can ensure that the lighting is installed correctly and complies with all safety standards.
- Avoid lighting with low IP ratings: Never use lighting with an IP rating lower than IP44 in the humid zones of the bathroom. This can create dangerous situations.
