Gee coffeemaker in the bathroom, never thought of that one. but fridge/freezer, beer taps, may as well convert it into a proper man cave and add an entertainment system too... now that is a place a man can call his own!
On a serious note, you can pick up little bar fridges nice and cheap, so there is no reason you couldn't try it out. Also if you have milk in your coffee, there is another good reason to have one in your bathroom!
How do the ice cubers stop their ice from melting? do you just do a dash to the kitchen when you have finished up?
