Fluff,
If it cools down too fast in winter just keep hollering to 'she who must be obeyed' for another beer and keep peeing in it. That's what we do in QLD. It's good for the lawn, makes the cane toads stay away and your missus will never want to get in and annoy your during bath and beer time.
Come to think of it we just sold our old enamel bath to a lady from Perth. What a coincidence.
