Shower downlights need to be IP65 rated, so they can withstand water from showers. This collection of downlights is IP65 rated, while maintaining a high standard of aesthetics and design. IP65 downlights benefit from a smooth, integrated design appearance. There are quite a few IP65 downlights with IP44 counterparts that you can use as complimentary downlights for the rest of the bathroom (which could lead to cost savings). 

Top Tip: Try to avoid placing a downlight directly over the shower head as it will create distracting shadows.
