How to soak your feet

My neice Keegan is on her feet alot at work. After a couple of 12 hour days, her feet hurt so much that she tries various things to make them feel better. I am always telling her to soak them in the tub. This is what I saw. She says she doesn't like to take a bath and sitting on the side wasn't comfortble. So she put a plastic chair in the tub, filled it up and was sitting there reading her Kindle. The things I missed when I lived alone.
