Frugal shower. Get in….straight away! Don’t worry if it’s cold; it will warm up in a few seconds. Wet hair. Turn shower off and lather. Turn on and rinse. Wash your body as you rinse. Use “washandgo” to save two lots of hot/cold/hot! hot!/too cold showering! When shower timer beeps: get out! Do all of the above whilst standing in a big bucket and then use water in bucket to flush loo………….or wash urine off floor from Dearly Beloved wetting himself laughing at my ridiculous attempts to save water and electricity!
