Cute mancave bathroom idea! 1. Buy a bottle of Jack Daniel's. 2. Buy a bottle of liquid soap - choose the fanciest pump you can find. 3. Pour soap into Jack bottle and screw on the pump. Please Note: I bought soap from the kitchen section@Target. The pump thread is a universal size, but be careful to get a pump that does not bulge out at the spring as it will not fit in the bottle neck.
