I have a bath almost every day, every morning before work. I find it helps me wake up and gather my thoughts. Its also nice and hot.
I've been told by my girlfriend that it wastes a lot of water, but she has seen how long I can stand/stay in a shower, and cannot use that reasoning anymore.
We do have a shower over the bath which she uses, and I do if I am in a hurry, but otherwise baths all the way.
