Taking a 5-minute shower uses 60 liters of water and 2.2 kWh of energy, while taking a bath uses three times as much water and energy at 180 liters and 6.6 kWh. For a family of four showering for 5 minutes daily, it would cost around 400 euros per year for hot water. Additionally, the energy used for one roundtrip international flight between Stockholm and Bangkok could fill a bathtub over 700 times.

Energy consumption
Bathtub vs Shower If you take a shower for about 5 minutes you will use about 60 liters of warmwater (approximately 40 °C). The energyamount is about 2.2 kWh (kilowatthours). Taking a bath instead will be a lot more energy-consuming beacuse you will use three times more water and energy, namely 6.6kWh and 180 liters of water, that’s a pretty big difference. According to our source it will cost a regular family ( 4 people) 4015 swedish crowns ( about 400€ ) if every member want to shower 5 minutes/day. These numbers will only be correct if the electricity price is 5 penny/liter.
Take a shower or a bath? Calculations 2.2kWh/5minutes = 0.44kWh/hours 60liters/5minutes =12liters/minute 12liters and 0.44kWh/minute 0,44kWh/12liter ≈0,037kWh/liter If you take a shower for 5 minutes you will use 60 liters of water. And if you are 4 members in a family it will look like this: 60liters x 4people = 240liters for 4 people to take a 5minutes shower every day ! 240liters x 365 days ( one year ) = 87 600 liter/year 87 600 liter costs 4015 87600liter/4015swedish crowns ≈22 (21.81818181) liter/swedish crowns! 22 liter costs ≈ 0.12 € You can warm up 22 liters water to 40°C for 0.12 €
One flight to Thailand and back! Did you know that… one flight with Boening 787 = 0.29 kWh/personkm It’s 8107 km to Thailand so 0.29kWh/personkm x 8107 km = 2351.03 kWh/person to Thailand ≈ 2400kWh/person One flight to Thailand and back again (from Stockholm to Bangkok) = 2400kWh x 2= 4800kWh/person 6.6kWh for a bath 180 liters warm water and 4800kWh for a trip to Thailand and back again. (from Stockholm) 4800/6.6≈727.272727≈727 ≈ 727 bath If you won’t go to Thailand for vacation you can fill your bathtub 727 times with the same amount of energy! Thai Air!
