Do you like to take long, and especially hot, showers regularly? Besides making your skin dryer you will also waste money and water (30% of all home water consumption is in the shower) on those long hot showers.
But fear not! Technology in form of "high-tech" sandglass timers is here to help you.
When buying a shower timer you should look for a four minute timer. Don't forget that the timer should also be waterproof!
But why four minutes and not just invest in a water-efficient showerhead and shower as much as you like? Because by using a brand new water-efficient showerhead for 15 minutes will still waste more water than a 4 minute shower under an old showerhead.
The sandglass timers from the image above come in six different waterproof designs and the price starts at $3 for the most basic one.
