An IP44 label on a luminaire is reassuring, but by itself it does not indicate where it can be installed in a bathroom. The location relative to the shower or bathtub, the electrical class, the power supply, and how the device is connected also matter. The risk would be to read 'splash-proof' as a general permission. Here is a cautious method for reading the zones, to help prepare your choice and ask the right questions to the installer, without turning a decorative item into wiring instructions.
To determine bathroom zones, consult the Legrand guide cited below and have the location checked by a qualified electrician.
What the two digits of IP44 mean
The IP rating describes the protection of a device's enclosure. The first digit concerns solid objects; the second concerns water. In IP44, the second 4 corresponds to resistance to water splashes according to the test specified for this rating. This does not mean complete waterproofing, the possibility of immersion, or automatic suitability for any water jet. An IP44 luminaire is not a luminaire that should be placed thoughtlessly in the shower.
The datasheets sometimes use IPX4: the X means that protection against solid objects is not specified in this notation, while the 4 indicates the level of protection against water. IP44 does have a second digit 4. This correspondence allows for studying the water requirement, but there are other electrical conditions to examine. Ask for the manual of the specific model rather than interpreting a photo or a commercial mention 'bathroom special'.
Why the bathroom is divided into zones
The French standard NF C 15-100 distinguishes zones around the bathtub or shower: 0, 1, and 2, then the space outside the zone. Their delimitation depends on the actual configuration, particularly the tray, the screen, and the dimensions. A rule read for a bathtub does not necessarily apply in the same way to a walk-in shower. The level of exposure to water is not uniform throughout the room.
The safe method is to take a measured plan before purchase. Mark the shower, bathtub, fixed walls, ceiling, and the intended location of the light point. Then, have the applicable zone determined for that location. A difference of a few centimeters can change the allowed equipment; do not just say that the lamp "seems far" from the faucet. The general condensation of the room does not replace this regulatory division either.
In zone 2, IP44 may be relevant
The Legrand guide indicates for zone 2 a water protection requirement of IPX4. Since the second digit of IP44 is 4, an IP44 luminaire meets this aspect of protection. This does not authorize just any device: the same guide distinguishes electrical classes and mentions, according to the case, Class II or extra-low safety voltage equipment. The connection, the manual, and the installation conditions must remain compatible with the zone.
This is therefore where precise wording matters: "IP44 may be suitable in zone 2" is not synonymous with "any IP44 is allowed." To select a model, require a datasheet where the IP rating, class, and installation instructions are explicit. If any of these elements is missing, do not fill the gap with a guess. A qualified electrician can verify the complete product and the location, especially in a bathroom that has been renovated several times.
In zones 0 and 1, do not extrapolate
Zone 0 is the area of direct water reception. Zone 1 is in the immediate vicinity, particularly above the shower or bathtub according to the delimitation rules. The Legrand guide associates stronger requirements and limited equipment categories with these zones. In zone 1, it mentions IPX5 for the authorized equipment. The 4 in IP44 does not become a 5 because the luminaire has a nice finish or a closed cover.
If your project includes lighting in these areas, do not start with a standard decorative luminaire. Have the installation designed according to the standard, with the compatible type of power supply, class, rating, and instructions. This article does not replace a compliance study or the manufacturer's requirements. It aims to prevent a common mistake: considering IP44 as a catch-all for the three zones.
Outside the designated zones still calls for care
Outside of zones 0, 1, and 2, the possibilities are broader, but the normal conditions for electrical installation remain. A luminaire must be designed for its environment, properly connected, and used according to its instructions. Moisture, insufficient ventilation, or splashes that exceed the theoretical zone may justify a more protective choice, but this assessment should not hide poor placement.
For a mirror located away from the shower, ask exactly where the edge of zone 2 is and how the lighting is powered. Also check visual comfort: a source too close to the face or placed only on the ceiling can create annoying shadows. Electrical compliance and the quality of light are two separate issues; deal with the first before choosing the glass tint or color temperature.
The product sheet to request before installation
Note the exact reference of the luminaire and check its datasheet for the IP rating, electrical class, supply voltage, and any installation restrictions. Two almost identical models can have different characteristics. If you add a replaceable bulb, also comply with the power limits and dimensions given in the manual. A so-called 'waterproof' bulb does not by itself make the luminaire enclosure an IP44 device.
Keep the manual for the installer. It may specify the orientation, seals, type of mounting, or usage limits. After installation, avoid modifying the fixture or removing a protective cover without a new check. A laboratory rating describes a device mounted under certain conditions; a missing seal or makeshift assembly can remove the benefit of this protection.
The right question to ask the electrician
Instead of asking 'Is this lamp for the bathroom?', indicate the reference, the side location, and ask: in which area is it located, what classes and ratings are required here, and does the manual allow this installation? The installer will be able to take into account the actual configuration and applicable rules. This avoids choosing a lamp solely based on a catalog photo showing a mirror and a bathtub.
If the answer requires a different model, review the project before ordering. Slightly moving the source, adding indirect lighting outside the exposed area, or choosing a documented product can solve the problem without compromising safety. It is better to adapt the lighting design to the room than to force a decorative piece into a location it was not designed to occupy.
IP44 and zones: what the rating alone does not say
| Location | Waterproof protection mark | Decision |
|---|---|---|
| Zone 0 | Strong specific requirements | Do not derive an IP44 authorization |
| Zone 1 | Legrand indicates IPX5 for the approved equipment | IP44 is not sufficient for this criterion |
| Zone 2 | Legrand indicates IPX4 | IP44 can meet the water criterion; check the class and installation |
| Out of zone | General rules and instructions | Check the real environment |

Do not claim an undocumented IP rating
We do not recommend any Lumora light for a bathroom zone without a documented IP rating and electrical class. Have the exact model and location checked before purchase.
Frequently Asked Questions
Is IP44 sufficient everywhere in the bathroom?
No. IP44 specifically describes protection against water splashes; the zone, the electrical class, the power supply, and the manual determine eligibility.
Can an IP44 light be installed above a shower?
Do not assume it. A location above the shower may fall under zone 1, for which the consulted guide indicates IPX5 and specific conditions.
Is IP44 completely waterproof?
No. Protection against splashes is not protection against immersion or all water jets.
Is an IP44 Class I model suitable in zone 2?
Do not infer authorization from this. The guide distinguishes the permitted classes; have the reference and the connection checked by a professional.
Choose the location before the light fixture
IP44 is useful information, but only part of the decision. Identify the zones, request the complete manual, and check the rating as well as the model's class with a professional. Safety of the installation comes before the decorative effect.
