how about using one of the aerated shower heads with a flow limiter? would reduce the amount of water used and the amount of gas used to heat the water.....just reread the op do when you say turn the power off is that because its an electric shower? if so just forget everything I have written
my 2 children are still very small but are just starting to enjoy showers so I am currently over the moon because we are saving water on not having to bath them every night....but give it a few years and will be joining you in dispair

Many yrs ago we had the same problem. I changed the bathroom shower to one that came off the hot water. Lift the header tank in the loft. Not sure about your problem as they will do what they want when you are away. Other than pull the fuse and they have to book a shower!

my son is a hygiene freak, i have turned the power off under the stairs when i realised he has sneaked into the shower, i cannot watch my kids 24/7, i be at the brekky table and then i would hear my daughter yelling to her brother because she cannot get into the bathroom then i start seeing red shout my head off, he comes up with the excuse that he was on the toilet but i cannot prove otherwise, one day the electric ran out i would not the switch it on then he huffed and then came with the phone and said it's mum and another domestic between us but she does agree with me until my son just turns on son and mother charm being the baby of the family is a spoilt little .... by his mother.
