IP Ratings for Bathrooms
IP (Ingress Protection) ratings indicate protection against water and dust. For bathroom installations, IP44 is the minimum for most areas, while Zone 0 requires IP67 for complete immersion protection.
Shaver Sockets
Shaver sockets must comply with BS EN 61558-2-5 and include isolation transformers for safety. They should be installed at least 2.25m above floor level and away from water sources.
