Product Features

Keep Your Routine, Save Your Hot Water

Countless gallons of hot water are unintentionally wasted at the start of every shower. This is because while waiting for the shower to get warm, people often leave to do something such as brush their teeth or go pick out their clothes.

Evolve's ShowerStart Thermostatic Shut-Off Valve (TSV) is a simple device that eliminates this problem. It allows you to effortlessly save the hot water and energy that’s used while waiting for your shower to get warm. It also lets you know when your shower is warm and ready.

How it Works

How does it work? It's simple:

1. Turn on the Shower
Turn on your shower and do all the things you would normally do while waiting for it to get warm.

2. ShowerStart Kicks In
While you're brushing your teeth or making coffee, ShowerStart kicks in and starts monitoring your water temperature. When it reaches 95 degrees Fahrenheit, it automatically lowers your shower flow to a trickle to save water. It will stay this way until you are ready to get in.

3. Shower is Ready - Just Pull the Cord
You know the shower is ready because you can hear it's just trickling. When you are ready to get in, just pull the cord to resume full shower flow.

Doesn't Impact Shower Pressure or Flow

Don't worry - ShowerStart features full flow pass-through so you can continue to enjoy the same pressure, comfort, and warmth you are accustomed to.

Makes Your Hot Water Last Longer

Not wasting gallons of hot water at the beginning of every shower means your hot water will last longer, saving you money on your energy bill.


ShowerStart fits between your shower arm and your existing showerhead. It can attach to any shower arm with industry-standard half-inch fittings.

The convenient, reachable pull-cord means you can even use it in showers for children, seniors, or people with disabilities.


Quick and Easy Install

Installing a ShowerStart TSV is as quick and easy as changing a light bulb. It takes just a few minutes and can often be done without any tools.
