How it works

Energy per shower = power × (minutes ÷ 60). Cost per shower = energy × rate. Monthly cost = cost per shower × showers per day × 30.4; yearly = monthly × 12. Shorter showers and a lower-power unit are the biggest savings.

Frequently asked questions

Are electric showers expensive to run?

Per minute, yes — they are high power. But they only run briefly and heat just the water you use, so total cost depends mostly on shower length and frequency.

Electric shower vs bath?

A short electric shower usually uses less energy and water than filling a bath, though a long power-shower can use more.

How do I cut the cost?

Shorten shower time, fit a more efficient shower head, and consider a lower-kW unit if your water pressure allows.
