There is often a cost to saving money. It would be nice to be rich enough not to worry.
But waste is for everyone to consider. And over-showering wastes money…and water.
The cost is the loss of the enjoyment of hot water on your back for 15 minutes…
15 minute showers can cost anything up to 50c depending on where you live.
You can always do better.
Take a kitchen timer into the shower with you and speed up – see if you can do your thing in under 3 minutes. Make it a game.
Brushing teeth and shaving can easily be done while NOT showering, but many do.
My husband actually turns of the shower while sudsing up his hair and body. A shower break!
