as I can plug in & shave my toothbrush
That's an interesting toothbrush!![]()
I'd say in the cabinet, but mainly from a cosmetic point of view. (I think when they're external, it makes it look a bit too hotely)
I have a cabinet with a shaving socket on the inside, and it works quite nicely, as I can plug in & shave my toothbrush etc whilst it's all within the cabinet, so it doesn't look messy.
