Baths are good for you; they relax your muscles and help your blood flow. They're kind of crap at getting you clean unless you have a spray nozzle to rinse off with afterward, though...which I don't, so I just use a drinking glass to pour water over myself with. Gets the job done.
So in answer to the original question, yeah, I'll take a bath when I'm stressed out or my circulation is bad, or when I need to get clean but also refuse to put down the book I'm reading.
