The last job I did was taking out a 10.5kw electric shower and installing a mixer. The old shower works fine etc. I was wondering about putting it outside at home for washing the dog. It is a complete pain putting her in the bath, and then she shakes and runs round the house like a loon. I have a space on the fuseboard. It was the possible cold damage to the shower that concerns me as obviously it is waterproof. Any thoughts?
