Here's the outdoor shower at our tropical love shack. Notice the electrical rating on the shower head. Down here, if you want hot water, you heat it where it's dispensed. This installation is tidier than most, which usually have wires sticking out everywhere. This one is taped up nicely and covered with a conduit. But I took a closeup of where the hot wires connect, and also a shot of the ground wire. This setup is commonly called the "suicide shower," for obvious reasons. We don't take hot showers when we're here.
