All calculations on this site are based on current fuel prices, they are checked regularly and calculations are automatically updated.
The costs calculated based on these fuel prices should be regarded as 'good estimates', given that fuel prices vary in different parts of the county and at different time of the year.
The calculations also have different levels of accuracy depending on the nature of the calculation. For example calculating the energy use of a known power output TV is very easy compared to calculating the effect on energy savings when insulating a cavity wall.

This is a complicated... So here are some rules of thumb:-
This is a complicated picture given the number of methods to heat the water and the flows of water that various showering techniques provide.
- A medium sized bath uses 150L of water, a power shower for 10 minutes uses about 150L of water, so a bath and a power shower could cost about the same, if the water used in both is heated in the same way. A low flow shower uses about 50L of water and in this scenario, would cost about a third the price of a power shower.
- Many of us have a gas boiler and an electric shower. Electric showers are low flow and in ten minutes may use 50L of water, however electricity costs over 3 times as much as gas at the moment and so surprisingly enough a shower and a bath in this case cost about the same.
Tour headline..How much does it cost to have a shower or bath.
Question not answered as you give no cost just comparisons of usage ???

10 minutes? I can shower, shave and dress in 10 minutes. Don't you have a job to go to? Or children to feed breakfast? Or both?
thankfully no, and they feed themselves
You use 10 minutes as a time.I get bored after about 3 minutes, certainly no longer that 5 minutes. Do I just stay dirty?
Ha Ha!I think I agree
