I prefer baths, but don't have one at home...so have no choice here. My parents in law do have one, so if I can be bothered to go over, THEN I'll have a bath!
There's always a ring of residue left in the tub after you drain the water if you've just shaved. Unless I were so inclined to scrub down the tub after soak #1 before soak #2, a shower would just be easier.
