Just got time to slot in this quickie. I know a lot of people couldn't do without their daily shower, I am not one of them. For a start I haven't got time to get myself wet, and dry myself off every single day, and I can't see how a quick waft over with shower gel can remove every bit of grime. Shower gel is the biggest con of all times anyway, we didn't need it years ago. Just because someone smells nice doesn't mean they are clean. And what about the extra washing you have to do with all the towels you use for a daily shower? Waste of water and energy.
This is how I keep clean. I have just washed my hair over the bath, and then had my fortnightly soak, full body exfoliation, pedicure, and I still have the water to use for washing my car.
For the hair wash I used Tesco Value baby shampoo, dead cheap at 8p a bottle. All I did for my exfoliation was use soap, (I've got stacks of this hand made soap), and a pair of scrubby gloves, which you can buy at a Pound Shop, they last forever.
I use a pumice stone on my feet, you can't do that while hopping about in a shower. I trim my toe nails over the bath so they go down the plug hole with the last drop of water left after the car wash, another job you can't do in the shower.
That's it, all dead skin removed, squeeky clean and job done. To finish it off I use cheap body lotion on my arms, legs, and neck, and cheap moisturiser on the mush. In between the baths, I boil a kettle of water and wash the bits that matter, thus only heating a tank of water on bath days. Of course if there was two of you, you could have a bogof. Buy one get one free by using the same bath water ;o)
