Bath vs showers: what uses more water?

It’s commonly assumed that baths waste far more water than a shower and that a shower is the more water efficient way of washing yourself. However is this true?

In this article, we will look at whether a bath or a shower uses more water.

How many litres of water are used?


A typical bath can hold approximately 80 litres of water.

While this might seem a lot, you probably wouldn’t fill a bath right up to the top which will reduce the typical bath’s water usage to below this amount.

Additionally, once you’ve filled up your bath, that’s usually the limit to what you’ll use. You’ll put in the plug, fill up the bath, wash yourself, then let the water out.


A typical power shower run for 8 minutes will use around 135 litres of water. This is obviously a lot more than a bath, so think about all the times you’ve had a 15 or 20 min shower and consider the amount of water that uses.

Because water isn’t contained in a bath, it’s so easy to get through a massive amount of water without even realising, especially with the increasingly-popular power showers.

Compare a power shower to an electric shower, where an 8 minute shower will use about 62 litres of water.

You can combine the relaxing feeling of a standard bath, with the therapeutic cascading effect of a power shower with the jet systems incorporated into a spa bath.
