IP ratings: which fitting for the bathroom, façade and pool
The IP code is followed by two digits: the first for protection against solids and dust, the second for protection against water. Choosing a lower rating than needed means repeated failures and a risk of short circuits.
The most common ratings
| Rating | Meaning | Use |
|---|---|---|
| IP20 | Protected against fingers, no protection against water | Dry rooms |
| IP44 | Protected against water splashes from all directions | Bathrooms away from the shower, covered balconies |
| IP54 | Partial dust protection and splash protection | Sheltered outdoor areas |
| IP65 | Dust-tight and protected against water jets | Above the shower, façades, gardens |
| IP67 | Withstands temporary immersion | In-ground uplights in gardens and walkways |
| IP68 | Withstands continuous immersion | Swimming pools and fountains |
The bathroom and its zones
Electrical regulations divide the bathroom into zones according to proximity to water: inside the bath or shower, directly above it, the immediate surroundings, then further away. In the closest zone, low-voltage fittings with high protection are used; above the shower, IP65 is the practical minimum; and away from water, IP44 is enough. The final decision rests with the electrical engineer, according to the applicable code.
Outdoors in the Gulf climate
Dust, coastal humidity and the heat of the sun test a fitting more than rain does. Choose well-coated aluminium or a stainless-steel grade suited to coastal environments, and check the quality of the gaskets and connections, since water usually gets in through the cable, not the body.
Related mistakes and comparisons
Common mistakeThe four bathroom Zones
“Electrically, a bathroom isn’t one area... it’s 4 zones! Getting this wrong causes short circuits.”
- The problem
- Installing non-sealed (IP20) fixtures in direct shower areas
- Technical explanation
- In engineering terms the bathroom is divided into 4 zones (Zone 0 for the tub, Zone 1 above the shower which needs IP44/IP65, and Zone 3 for dry areas)
- The result
- Protecting your family from electric shock, and choosing fixtures that last a long time without rusting
Common mistakeBuying IP20 lights for the bathroom
“Putting an ordinary spotlight in the shower ceiling and wondering why it gives shocks?”
- The problem
- Using non-sealed fittings in Zone 1, which is exposed to steam and water.
- Technical explanation
- The area directly above the shower needs fittings rated IP44 or IP65 to withstand steam.
- The result
- Protects your family from electric shock.
ComparisonIP20 indoor light vs IP44 for bathrooms
“Installed a standard spotlight in the bathroom ceiling? Watch out for the humidity!”
- The problem
- Lamps failing and frames rusting quickly because of steam.
- Technical explanation
- Directly above the shower area, use sealed fittings rated IP44 at minimum, or IP65, to stop steam condensing inside the electronic chip.
- The result
- Less maintenance and lasting performance for years in the humid bathroom environment.
ComparisonIP65 vs IP67 lights
“Not every outdoor light can go into your garden floor!”
- The problem
- In-ground lights failing because of pooled rain or irrigation water.
- Technical explanation
- IP65 protects against water jets and is excellent for facades. But lights set into the ground need IP67 (protection against temporary immersion in water) to withstand irrigation water and rain.
- The result
- Fittings that last for years in the garden soil without burning out.
ComparisonIP20 vs. IP65 fixtures in the bathroom
“Why do your bathroom lights keep flickering and failing? You’re choosing the wrong protection!”
- The problem
- Electronics damaged by steam
- Technical explanation
- IP20 is meant for dry rooms. Directly above the shower you must use IP65, which is fully sealed against water spray and steam
- The result
- Safety for your family from short circuits, and savings on replacing burnt-out lights
ComparisonZone 1 vs. Zone 3 in bathrooms
“Not all your bathroom lights are the same... pay attention to the protection code!”
- The problem
- Using non-moisture-resistant fixtures in the shower
- Technical explanation
- Zone 1 (above the shower) requires IP44 or IP65. Zone 3 (outside the water area) only needs ordinary IP20
- The result
- Save money by not buying IP65 for the whole bathroom, and use it only where the risk is
Comparison5° ground Up-light
“Lit up your façade and all the light shot off into the sky?”
- The problem
- Using wide ground lights for tall columns
- Technical explanation
- Tall, slim columns need a very narrow Beam Angle (5°–10°), almost like a laser, to focus on the architecture without polluting the sky
- The result
- Clearly showcasing the height and grandeur of the villa
Common mistakeLeaving fixtures dirty
“Your lighting suddenly got weaker? Don’t change the light, just clean it!”
- The problem
- Dust building up on polished reflectors reduces their efficiency by up to 30%
- Technical explanation
- Aluminium reflectors are affected by fingerprints and dust. Regular maintenance and wiping with a soft cloth restores most of their efficiency
- The result
- Longer fixture life and no money wasted on needless replacements
