Near the tub or shower, the lamps must have the degree of protection IP 67. They are waterproof for temporary immersion.
At surface and 2.25 m around the toilet and bathtub or shower tray is the right IP65 degree of protection for your lights. They are protected against direct water jets.
Up to 60 cm around the tub or shower wall up to 2.25 m take lamps with IP44 protection, making them waterproof.
