Shave only, about 30 minutes; but I'm still kinda new to wet shaving so I take my time. The only face prep' I do is with warm water prior to shaving since I typically haven't showered immediately before.
Door to door 25-30 min shower + 3-pass shave. Shower is probably only five-ish minutes. Add 10 minutes if using a straight (I am still incompetent with one).
