Odd discussion with wife last night.
How do you draw your bath :).
I like to fill it up slightly - to a warm temperature..
Then i get in and swish the hot water behind me, getting the entire bath to an even heat.
Plus as i'm in the bath as it's filling, i adjust to the heat more quickly and can have a very warm bath. Without the "Sting" you normally get from getting into an already drawn bath, then having to stop top it up with warm because you've gotten used to it.
