The Showerdome® shower top was invented by Ken Evans, an engineer living in Tauranga, New Zealand. He was at home watching rugby one night and at half-time put the kettle on to make a cup of tea. He had a glass kettle and noticed the steam only formed a cloud when it met the colder air in his kitchen. The steam inside the kettle remained absolutely clear.
Ken had been battling condensation in his bathroom for years. He immediately put a piece of plywood over the top of his shower and left it running during the second half of the game. When he returned, his bathroom was completely moisture free and his shower was crystal clear.
After years of careful research, testing and development, Showerdome was patented and is now sold around the world.
