Shorter showers are one of the most impactful ways to conserve water and energy as hot water is our most costly water. Most people take ~8-10 minutes to shower, but for others this can be even longer and a number of times a day. 4 minutes is the duration recommended by utilities for sustainable showering. The ShowerStar Shower Sensor Timer & App can help you achieve this.
The ShowerStar Shower Sensor & App is an award winning, purpose built timer for showers that completely reimagines the basic shower timer using behavioural science to nudge people to take shorter showers:
2 minute DIY install - No tools. No plumber. Fits any shower.

Smart flow detection - Turns on automatically - no buttons to press.

Families love it. The planet does too.

A 'piece of cake' to install and we've been using it for nearly 3 months. The savings are much larger than expected simply by shortening the length of our showers. Our energy and water bills are normally staggering and it has paid for itself in under 3 months. Really impressive gadget.

I love this product. We nag our kids a lot less and they've learned a lot about how a simple decision to have a shorter shower can have a big impact. Ideal for families with kids looking for ways to save money and learn about conservation.

Really surprised by how much money we can save with shorter showers. We had no idea we were literally pouring money down the drain.
