Shower ofc!
Bath sucks and dont get you clean:
there are about 200,000 bacteria per square inch in your tub.
That's right, according to the Global Hygiene Council, your bathtub is full of all sorts of bacteria, including E. coli and streptococcus, as well as staph aureus (commonly know as staph infection).
To make matters worse, because tubs rarely dry out completely, they become breeding grounds for unseen bacteria even when you're not in the tub. The situation is so bad that NYU microbiologist Dr. Phillip M. Tierno has said that soaking in a bathtub is like sitting in “bacterial soup.”
