Save the hot water that you leave running before you get in the shower with the Evolve ShowerStart Roadrunner Low Flow Showerhead. This clever showerhead holds the hot water in until it's ready to use. That means the Roadrunner will save you up to 8 gallons of water for every 5-minute showers you take!

How It Works

The Evolve Roadrunner Showerhead is a non-aerating, low flow showerhead. The ShowerStart™ technology behind the Roadrunner monitors the water temperature and “triggers a trickle as soon as the water reaches 95 F (35 C). When you hear the “hot water is ready trickle, simply flip the switch on the showerhead to start your warm, luxurious shower. When you're done, the showerhead automatically resets itself for the next shower. So, there's no more guessing or guilt about running hot water down the drain – only the newfound freedom of knowing you're actually saving hot water, while your shower is warming!
  • Non-aerating means air is not mixed into the water stream, as it passes through the showerhead; as a result, less temperature is lost between the showerhead and you.
  • ShowerStart™ technology behind the 1.59 gpm low flow showerhead will save you up to $246 and 8,212 gallons** of water and energy per year!
  • Pressure Compensating Technology means you will have consistent, even pressure regardless of water pressure.
  • 54-nozzle, full face spray means you will enjoy the comfort and warmth of the better coverage.
