Bath vs Showers | Which Is Better Water Usage?

Like the debate on which really came first, the egg or the chicken, there’s also this question that a lot of people ask – which is better water usage, bath or showers? Some of you may be on the bath side, while others may bet on shower.

At first glance, it seems that shower is a sure win in the bath vs shower battle on which of the two offers better water usage. Let’s take a look deeper in the baths vs showers arena and get the facts so we could find the answer to this question and see if your side wins or not.

Statistics on Average Use

bath vs shower showdownBased on a study that was made, the average time that Americans spend in the shower is 8.2 minutes. The standard flow of water on shower heads is 2.5 gallons per minute. Doing the math, you will probably consume around 20.5 gallons of water for an average shower time with a standard water flow rate. So what about the average amount of water used when taking a bath?

An average bathtub could contain 50 gallons of water. Since you would still be soaking in the tub, you would probably use about 45 gallons to prevent spilling and you will be able to enjoy a full bath. You may also fill it in half, which will use lesser water. This would be around 25 gallons. As you could see, shower clearly wins in this bath vs shower, based on the average usage.


The Bath vs Shower Showdown is Not Yet Over

You might be wondering why the battle is not yet over when we already got the answer to the question. The reason why we’re still having this baths vs showers discussion is because if we dig really deeper, the answer really depends on the situation.

bath vs shower showdownThis might seem like the answer is not specific, but really, there are various factors that affect the usage of water, which we will go through here. The data information above is only the estimated value based on standard or average usage. However, what if you don’t fall in these categories? This could change the game on the water usage of shower vs bath battle.

So what are the factors that affect the amount of water used? There are three factors to consider for determining if you would save more water on baths or showers. They are the time you spend on shower, flow rate of shower head and size of the bathtub.

As you may already know, the average shower time in the US is 8.2 minutes. If you spend shorter time in the shower, then you would be using lesser water. However, if you’re the type of person who stays in the shower for a longer time, this would also mean more water usage.

Say you take 15 minutes in the shower on a standard water flow rate; you will be using 38 gallons of water, which is more than a standard half full bath. Then there’s also the flow rate on the shower head. A long 20 minute shower on a standard flow rate would cost you 50 gallons, which is more than the amount of water you would use in a standard bath. However, if using high flow shower heads, you’ll use about 5.5 gallons per minute or 45 gallons for an 8.2 minutes shower.

Imagine taking a 20 minute shower and it will cost you 110 gallons. The size of the bathtub is also to be considered. Smaller tubs use lesser water. However, if you have a bathtub that is bigger than standard, it would obviously use more water.

So Which Is Better?

After digging thoroughly, you might already agree that the winner on the shower vs bath water usage battle depends on the situation. Now that you know the factors affecting the outcome, you could try computing it yourself so you would know the best option to save on water usage.
