Bathroom lighting zones in Belgium

Planning bathroom lighting in Belgium is not only about style. Start with a clear lighting plan so you can zone, place and specify correctly. To keep you safe around water, the RGIE defines bathroom lighting zones with specific IP ratings and distances. Use the guidance below to choose compliant fittings and place them with confidence.

IP ratings at a glance

IP ratings show how well a fitting resists dust and moisture. The first digit covers solids, the second covers water. In bathrooms you mainly care about the second digit. Typical levels: IP44 splash proof, IP65 resistant to water jets, IP67 suitable for temporary immersion. Dry areas can use IP20. Check that gaskets are sealed and drivers are protected so the real-life installation maintains the claimed IP rating. For suitable (IP-rated) options, browse wall and ceiling lamps.

Bathroom zones under the Belgian RGIE

Under the Belgian RGIE, the bathroom is split into zones around the bath and shower. Heights are measured up to 2.25 m and horizontally 0.6 m from the bath or shower edge. Protect the bathroom circuit with a 30 mA RCD. These are the bathroom lighting zones Belgium rules inspectors apply:

• Zone 0 - Inside the bath or shower basin. Use luminaires rated IPX7 or IP67. Only SELV up to 12 V is permitted, with the transformer placed outside the zones.
• Zone 1 - Above the bath or shower up to 2.25 m. Minimum IPX4, with IP65 recommended for shower spray. Prefer SELV 12 V with the driver kept outside zones 0-2. Fixed fittings only - no wall switches or sockets.
• Zone 2 - The area extending 0.6 m beyond zone 1 up to 2.25 m. Minimum IPX4 (IP44). Suitable for mirror and wall lights rated IP44 or higher. Only isolation-protected shaver outlets that comply are allowed.
• Outside zones - The rest of the room. IP20 is acceptable where no splashes occur, but IP44 is prudent near basins. Keep drivers, junction boxes and transformers outside zones 0-2, and place switches outside the bathroom or use pull-cords.

What to use and where

• Shower area - Recessed downlights in zone 1 with IP65, fixed beam and corrosion resistant trims.
• Mirror lighting - In zone 2, choose IP44 linear lights above the mirror or twin sconces at eye level. Aim for CRI 90+ and 2700-3000 K for flattering tone. Not sure about brightness? See how many lumens you need per room.
• General ambient - An IP44-rated ceiling light gives uniform fill. Add a dimmer for evening comfort and brighter task light when needed. Outside the strict zones, portable and rechargeable lamps can add soft, indirect light. For example, the Carrie LED Lamp IP44 provides damp-rated flexibility.

Common mistakes to avoid

• Hanging pendants in zones 1 or 2.
• Using non-sealed drivers in humid ceiling voids.
• Installing switches or standard sockets within zones.
• Ignoring gaskets and corrosion resistance near the coast or in steamy rooms.

FAQ

What are zones 0, 1 and 2 in a bathroom?

Zone 0 is inside the bath or shower basin. Zone 1 is above it up to 2.25 m. Zone 2 extends 0.6 m beyond zone 1, also up to 2.25 m. Each has minimum IP levels.

Where should you place lights in a bathroom?

Use IP65 downlights in zone 1 over the shower, IP44 mirror lights in zone 2 at eye level, and IP44 ambient ceiling light outside zones. Keep drivers and switches outside zones.
