Tips to Saving Energy in the Bathroom

Was the electricity bill slightly higher than you expected in the past quarter, even if it is significantly lower than before? Do you want to reduce it further? Two major benefits of reduced electricity use are that you protect the environment and get lower electricity bills. Here are some of the energy-saving tips available for your bathroom.

The shower

The shower devours energy is something most people are aware of, but few know that every minute less that you showers make a difference. Did you know that if you shower 5 minutes a day, instead of 15 minutes, you can reduce your annual electricity consumption by about 700 kWh?

Choosing to shower instead of bathing also has a positive impact on your energy use. It is estimated that a 3-minute shower corresponds to approximately 36 liters of hot water, a shower of 10 minutes takes approximately 120 liters of hot water, and a filled bath corresponds to approximately 150 liters of water.

Look over your nozzle. If you switch to a flushing shower nozzle that usually gives 5-7 liters per minute, from a regular nozzle that gives 12-14 liters per minute, you reduce the volume of water consumed by up to 70%.

Do not forget to make sure the shower nozzle is full and that it does not drip water.


Just cranes can be a great energy thief if you don’t look over them. If a crane stands and drips or if the toilet leaks, this can draw a lot of energy over the year. Did you know that a dripping water tap can drain away 700 kWh per year, even if cold water is drained away?

If you have a two-handle mixer, you can switch to a one-handle mixer and it may be good to switch to low-flush nozzles where possible. Changing gasket at dripping tapping points also prevents dripping.

Do not forget to test whether your shower is flushing or not. If it takes 50 seconds for your shower to fill a ten-liter bucket, you have a nozzle that provides 12 liters per minute. This is not a flushing shower nozzle and it can be good to see if it can be changed.


Water itself is an asset you should not waste, and turn off the water when you are not using it. Did you know that we use about 75-100 liters of hot water per person per day? Calculated in kilowatt-hours it is 1100 – 1800 kWh per year and a whole 3-5 kWh per day. If you do not turn off the water when you shampoo your hair, brush your teeth or wash your face, this amount of water increases and a large part of the water you consume runs straight down the drain unnecessarily. It is estimated that if you let the water run out when you brush your teeth, six liters per minute extra are wasted, water that no one uses.

If you can manually set the temperature of the hot water in your house, + 60 ° C is recommended. Partly because the temperature must exceed + 55 ° C to avoid legionella bacteria, but also because in a home you do not need to have warmer water.

Do not forget to turn off the tap when not using the water!


In the bathroom, just like in many other rooms, you have appliances that fulfill different purposes and that often consume electricity. If you also have a towel dryer and underfloor heating, you can use a lot of energy in a room you do not stay in all the time.

If you use an electric towel dryer, a timer is recommended. With the timer, you can set it to switch off after 30 minutes or the desired time. If you allow a towel dryer to run, it can draw around 600 kWh per year.

Do not forget that even the hairdryer draws electricity. If you have time to air-dry your hair, we recommend it for further energy savings.
