The single, 10-minute long shower will cost you $0.46 or $168.93 if you repeat it daily for a full year. Don't forget that these are sample calculations for one person and 10 minutes for showering only 1 time a day.
So, if we assume that the average person takes a 10-minute shower, you can expect to spend around 35p per shower on electricity. This is based on the calculation: Power (8.5kW) x cost per kWh (0.25) / 60 = 0.035, the cost per minute.
Generally, taking a shower uses less water than a full bath. A standard showerhead flows at a rate of 2.5 gallons per minute . This means that a ten-minute shower only uses 25 gallons of water.
Following our calculations based on a 10-minute shower, you can expect to spend 73p per electric shower and 40p per gas shower. Overall, it's cheaper to run a gas shower. However, fear not, as there are plenty of ways to cut costs on your energy bills irrespective of what kind of shower you use.
For an average middle-class household in South Africa (LSM7-10), a 10-min shower costs over R24 if you have a 'standard' 15 litre/min showerhead! This is about R2. 43/min. By changing to a low-flow showerhead and reducing shower time to 6 minutes, you can dramatically reduce this to about R7.
What costs the most on your electric bill? Heating and cooling are by far the greatest energy users in the home, making up around 40% of your electric bill. Other big users are washers, dryers, ovens, and stoves. Electronic devices like laptops and TVs are usually pretty cheap to run, but of course, it can all add up.
In fact, heating the water to a pleasant showering temperature is at least twice as expensive as the cost of the water itself. Accordingly, water heating can quickly drive up utility bills and accounts for roughly 10-20 percent of an average household's energy bill.
Showering daily would come to $64.54 per year per person and using the bath daily would be $195.68 per year per person, approximately three times more expensive.
The electric shower is generally more efficient and cheaper to run with less water being wasted; however, you risk spending extra on your electricity bills if you're on a high tariff.
What makes an optimal shower then? Ideally, it should be about 5 to 7 minutes and no longer than 15 minutes, says Yousuf Mohammed, PhD, a senior research fellow in dermatology at the Frazer Institute of the University of Queensland in Australia.
The total running time of this kind of shower can last less than two minutes – using an initial thirty seconds or so to get wet, followed by shutting off the water, using soap and shampoo and lathering, then rinsing for a minute or less.
Flush Facts
Design improvements have allowed toilets to use 1.28 gallons per flush or less while still providing equal or superior performance. This is 20 percent less water than the current federal standard of 1.6 gallons per flush.
That's why Lipoff suggests using lukewarm water instead of hot (the higher the temp, the more it'll dry you out), keeping showers under 10 minutes, and going easy on the soap (which can also have a drying effect). Ditching washcloths and loofahs goes a long way, too.
If you have a low-flow showerhead installed, you can expect to use about two gallons of water per minute, equalling 20 gallons throughout a 10-minute shower. With a standard showerhead, around half a gallon more water will emerge each minute, so a 10-minute shower would use somewhere close to 25 gallons.
Most dermatologists say that your shower should last between five and 10 minutes to cleanse and hydrate your skin, but no longer than 15 minutes to avoid drying it out.
The cost of a 10-minute shower with a "low flow" shower head in California would be $0.10. To determine the cost of a 10-minute shower, we need to calculate the total amount of water used and then calculate the total cost based on the price per gallon of water.
Save money with shorter showers
You'll save money in water, gas or electricity for heating it, or both. The cost of your water heating system accounts for about 18% of your home's utility bill, the second largest utility expense, according to the Department of Energy.
The energy needed to heat the water to run an 80-litre bath at 42C, on the other hand, will cost you 81p, more than three times the cost of a shower. An eight-minute shower using an electric shower will also use around 40 litres of water, half that required to fill a bath.
Prefabricated shower kits are often more affordable than sourcing individual components separately. These kits provide a convenient and budget-friendly solution, as they are designed to work together seamlessly while minimizing costs.
The average shower head flows 2.1 gallons per minute. 30 × 1000 gallons = 30,000 gallons. SO: If they showered for 30 minutes a day it would take them approximately 470 days to use up $45 of water.
Many doctors say a daily shower is fine for most people. (More than that could start to cause skin problems.) But for many people, two to three times a week is enough and may be even better to maintain good health.
Heating and cooling: 45-50%
The largest electricity consumer in the average household is your heating and cooling appliance. By a long shot. Central air conditioners and heaters use tons of energy in order to keep your home set to the right temperature.
If you have a water meter, the more water you use, the more you'll have to pay. And with personal bathing making up 33% of our overall water usage, the amount you use when taking baths and showers will have a big impact on your bill.
