How to Save Energy in the Bathroom

Bathroom energy saving tips for modern homes
Over the last decade or so, bathroom technology has evolved tremendously. Gone are the days of just a bath, basin, and toilet! Modern bathrooms now feature incredible gadgets that transform the average wet room into a sanctuary. From heated towel rails and underfloor heating to steam showers with in-shower entertainment and automatic toilets, these innovations have become commonplace. But with these comes increased energy consumption.
So if you’d like to cut down on your energy bills, your bathroom is a great place to start. In this article, we’ll explore practical ways to save energy in the bathroom.
How to save money on your energy bill
We love our electric toothbrushes, shavers, hair straighteners, heat lamps and illuminated mirrors - they make our daily routines easier and more comfortable. But, they can also drive up our energy bills. Before you buy, it’s important to know the hidden costs of these appliances, as well as larger factors like hot water heaters and leaks, which can significantly impact your monthly expenses. The good news is, there are simple ways to save energy without giving up any of the convenience.
Install an energy efficient hot water heater
When it comes to saving money, focusing on the biggest energy users is key. The hot water heater often tops the list as the largest electricity consumer in both the bathroom and the home. Mineral deposits can build up inside the tank over time, causing it to work harder to heat water efficiently, which in turn increases electricity usage. Here are some tips to ensure your hot water heater isn’t consuming more energy than it needs:
- Regular maintenance: If your hot water heater is less than 8 years old, schedule regular maintenance with your plumber to flush out mineral deposits.
- Consider replacement: For older units (over 8-10 years), consider upgrading to a new energy-efficient heat pump hot water system. Moving the hot water system closer to the taps you use most frequently and insulating the first two metres of pipes leading from the system can also improve efficiency.
- Heat trap and insulation: Ask your plumber to install a heat trap near the hot water outlet and insulate exposed pipes to minimise heat loss.
- Recirculating pump: Installing a recirculating pump system can also help reduce energy wastage by ensuring hot water is readily available at the taps.
Turn on the timers
Time management is key to creating an energy-efficient bathroom. Consider connecting all your electrical bathroom appliances, underfloor heating, and heated towel rails to timers. During the summer months, remember to switch off the underfloor heating and heated towel rails when they are not in use.
Lighten the load
Reduce your electricity use by replacing your current lighting with compact fluorescent lamps (CFLs). CFL bulbs can use less than 70% energy than incandescent bulbs, than traditional halogen bulbs while providing the same amount of light.
Fix any leaks fast
Addressing leaks promptly can save both water and energy. Did you know that a dripping hot water tap can waste 24,000 litres of water a year. Replace washers and seals to fix leaks promptly and reduce water and energy waste.
Simplify and don’t standby
Speaking of toothbrushes and razors that require charging: it’s best to avoid them! While these devices are convenient to use, they often stay plugged in after use, adding to your electricity bill.
Devices in standby mode can add up to 6% of your electricity bill. Consider switching to manual equivalents to save money and reduce frustration. How many times have you reached for a device only to find its battery empty? When it comes to investing in an energy efficient shower or energy efficient hot water heater, look out for Energy Star certification.

Switch to energy-efficient appliances
Upgrade to energy-efficient bathroom appliances like low-flow showerheads and taps. These products use less water without compromising performance, helping you save on both water and energy bills. Look for appliances with high Energy Star ratings for superior energy efficiency and performance standards.
Natural lighting and ventilation
Encourage using natural lighting during the day in your bathroom to reduce reliance on artificial lights. This not only enhances ambiance but also cuts down on energy consumption. Proper ventilation is essential for maintaining indoor air quality and preventing moisture buildup, reducing the need for exhaust fans. Emphasising natural lighting and ventilation promotes a more energy-efficient and comfortable bathroom environment.
Behavioural changes
Simple habits like taking shorter showers, turning off lights when not in use, and promptly fixing dripping taps can complement hardware upgrades. These changes can significantly reduce energy and water consumption in the bathroom.
Do bathroom heat lamps and fans use a lot of electricity?
When considering energy efficiency in your bathroom, it’s natural to wonder about the electricity consumption of heat lamps and fans. Bathroom heat lamps can indeed use significant electricity, especially if left on for extended periods. Consider using them only when necessary and installing models with timers or energy-saving features. Similarly, bathroom exhaust fans are essential for ventilation but can also consume electricity. Opt for energy-efficient models and use them wisely to minimise energy usage while maintaining indoor air quality.
The final word
Bathrooms are a common high energy-usage area in your house, but, by incorporating the above tips on energy efficiency, you can have a modern bathroom at a fraction of the energy cost. These small changes can have a big impact on your energy bills.
