Water companies measure water usage in hundred cubic feet, or CCF. One CCF is equivalent to 748 gallons of water. If you shower 10 minutes every day for a year, you are using 9,125 gallons of water (12.2 CCF). If you take a bath filled halfway every day for a year, you're using 14,600 gallons of water (19.51 CCF).
Are electric showers expensive to run? 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.
If a standard showerhead is fitted, it will use around an extra half a gallon each minute, accounting for a 25-gallon emittance every 10 minutes, or 50 gallons throughout a 20-minute shower. *1 gallon = 4.54 litres.
Assuming tenants shower about once a day on average, the annual cost per apartment is around $117 per year. On the other hand, a standard showerhead uses about 2.5 gallons per minute, which translates to 20 gallons in 12 minutes and increases the yearly cost to nearly $200.
Extra showers, more lights, and adjusting the thermostat even just a couple degrees can all add up to a higher electric bill.
A long, hot shower is great, but it wastes a lot of water. By shortening your shower by just four minutes, you can save up to 4,000 gallons of water per year. This can cut your bill by about $100 annually. Taking shorter showers may also help lower your gas or electric bill.
The energy required to heat the water for an 80-litre bath at 42C, on the other hand, will cost you 81p, which is more than three times the cost of a shower. An eight-minute shower with an electric shower uses approximately 40 litres of water, which is half the amount required to fill a bath.
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.
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.
On average, approximately 70 percent of that water is used indoors, with the bathroom being the largest consumer (a toilet alone can use 27 percent!).
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.

Not only can taking shorter showers save money, but it can also save an incredible amount of water. The standard showerhead uses about 2.5 gallons of water per minute. If you shaved 1 minute off your daily shower, you could save more than 900 gallons of water per year.
LIMIT SHOWERS TO 10 MINUTES
A shower uses about 6 gallons of water per minute. A 10-minute shower will limit the water consumption to about 60 gallons per wash.
The average American shower uses 17.2 gallons (65.1 liters) and lasts for 8.2 minutes at average flow rate of 2.1 gallons per minute (gpm) (7.9 lpm).
It's easy to underestimate how much water you use daily, but small habits can add up. Factors contributing to high water usage may include: Long Showers: Spending extra minutes under a warm shower might be relaxing, but it can also substantially increase your water bill.
According to the Environmental Protection Agency (EPA), the typical shower head sprays about 2.5 gallons per minute. If you take a shower that lasts 20 minutes, about 50 gallons of water are used. Some high-powered shower heads can use between 20-35 gallons of water for a five-minute shower.
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.
Assuming that the rates of electricity and water in your area are near the national average, 12 cents per kilowatt-hour and $1.50/1k U.S. gallons, each shower will cost you 25 cents or 51 cents per day for the whole household, according to the shower cost calculator by Omni.
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.
According to the U.S. Environmental Protection Agency (EPA), a full bathtub requires about 70 gallons of water, while taking a five-minute shower uses 10 to 25 gallons. You might argue that very few people fill the tub to the top, but a simple calculation shows that either way, baths use more water.
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.
