Only if it's a bubble bath. Studies have shown that people who spend long periods of time in bubble baths end up being very clean, as well as wet. I'm sure that if the water was warm, then one would exit the tub feeling clean, wet, and warm, as well.
While I think it would work for reading in the bathtub to stay relaxed, I've found that toasting pop-tarts is better performed in a drier area, like a kitchen. I have paid dearly for this, and can no longer blink, nor enjoy future bubble baths.
