An outdoor shower needs to cope with constant exposure to sun, rain and changing weather, which is why we build every design from copper and brass rather than materials prone to rust or corrosion. Copper ages well outdoors, developing a natural patina over time instead of breaking down the way some metals do.
That means the shower keeps working, and keeps its character, long after a standard fitting would need replacing. We see durability as just as important as how a shower looks, since a design only really earns its place once it's proven it can handle being outside every day, through every season.
