1. Turn on shower.

Cold water exits. You can continue with your typical routine—the things you do while waiting for the shower to become warm.

When water reaches 95°F, ShowerStart automatically lowers the flow to a trickle—saving hot water until you are ready to get in.

You will know when the shower is warm, so they can pull the resume fill flow and begin showering.

More hot water for other uses.

Freedom while waiting.

Mornings are better when you don’t have to choose between wasting time or wasting hot water. Now you can brush your teeth, shave or pick out the perfect outfit … and your shower will just wait for you.
