Taking a bath or taking a shower: which costs more? How much does it cost to run a bath? What is the cost of taking a shower? All shall be revealed…
We often think that things as trivial as taking a bath or having a shower won’t make any difference to how wealthy we are and will be in the future. Well, prepare to be amazed…
In fact, the cost to run a bath (or the cost to take a power shower) is significantly more than the cost of taking a shower. If we multiply this impact over a year, or a lifetime, of taking baths or showers, the numbers become quite remarkable.
Then, by using comparison services like The Energy Helpline, you could end up saving even more. Just click on the image below, pop in your postcode and current usage, and they will tell you exactly how much you could be saving each year on your gas and electricity:
How Much Does It Cost To Run A Bath?
Ahhhhh. Plenty of water, plenty of bubbles, even the rubber duck! Many people love taking a bath. But, do we realize how much it costs to run a bath?
It is estimated that it costs between 30p and 90p to take an 150 liter bath, depending on the efficiency of your boiler. If you are taking a bath twice a day, you would use an average of 300 liters of water each day, at a daily cost of £1.20 and an annual cost of £438.
How Much Does It Cost To Take A Shower?
Less. Much less. The average (eight-minute) standard shower only costs between 20p and 30p, using only 50 liters of water. You can work out from this how much your shower costs depending on the time you spend when you take a shower.
If you are in and out in 3 minutes, then each shower is probably less than 10p, However, if you are like this guy…
So, clearly saving 100 liters of water each time you take a wash is good for the environment. But, you may not appreciate how good it is for your bank balance. Two of those average showers a day based on these figures gives a daily cost of around 50p, with an annual cost of £161.
Therefore, by switching from taking a bath to having a shower, you could be saving over £250 a year.
Should We Be Taking A Shower So Often?
So far, we have referred to washing twice per day. Whereas this is fairly normal in modern society, it is not considered to be necessary for personal hygiene reasons, and could even be detrimental to the health of your skin.
Instead, it is generally accepted that from a health perspective (other than after vigorous exercise or labour) taking a shower twice per week will suffice if one washes themselves down with a cloth on a regular basis in between.
For many of our readers (myself included), this is a little controversial, but this could lead to some significant savings if adopted.
How Much Does It Cost To Have A Power Shower?
So, we should all be taking a shower instead of taking a bath. Right? The end. Not so fast…
There are many different showers on the market and their efficiency vary greatly. Power showers use significantly more water and therefore cost a great deal more. Whilst these may be pleasant to take, there is little evidence that these provide any hygienic benefits.
The average power shower is estimate to use 272 liters for two average showers per day, which is almost as much as taking a bath twice a day. In comparison, if you make use of a water-efficient shower head, you could reduce your daily water usage to just 62 liters (compared to 100-120 liters from a regular shower).

Taking A Bath Or Shower: Money Saving Tips
- If you are taking a bath, only use the amount of water you need – there’s no need to fill it right to the top.
- You should be taking a shorter shower. If you can reduce that average eight minute shower by two minutes, you’ll reduce your costs by 25% (which with a power shower represents over £100 per year). Not only that, but you’ll have over 12 hours extra each year to earn some other passive income!!
- Install a water efficient shower-head. Many are available for less than £20 – and the savings on your water and energy bill mean you’ll get that money back very quickly.
- This shower-head costs around £40, but as the analysis above shows, it could save you over £70 in a year compared to your normal shower-head. It’s funny to think of shower-heads in terms of ROI, but £30 profit in one year on an investment of £40 is an ROI of 75%. When you think that savings rates at the bank are less than 1%…
