Cost to run a bath

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:

Taking a bath or taking a shower

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.

So, we should all be taking a shower instead of taking a bath. Right? The end. Not so fast…

Taking a shower

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).

  1. Do you know how relaxing baths can be? Can you really put a monetary value on such a high level of R&R. Do you realize that your well-being will directly affect how successful you are at work?

    Anybody who says no to power showers and no to bath tubs to save money for 25 years is an idiot.

    • When you have 7 people in the house all wanting baths and a dual fuel bill of over £270 per month believe me switching from baths to showers does NOT make me an idiot. Thank you
