Well the sunken bath is a nightmare to clean because there isn't space enough around the edge of it. The only satisfactory way I've found is to take shoes and socks of and stand in the bath to clean it - not something that I was keen on doing when it was full of dice mice. I'm quite surprised I didn't injure myself given how much time I spent wobbly perched on the edge, leaning down to pick up dead mice and then scrub.
