No (well not in my case) as if I wasn't cycle commuting I'd be having a shower at home before going in to work. All cycle commuting did was move my shower from home to work, it doesn't add an extra shower and so doesn't add any extra time. I did shower again after cycling home, but that often replaced the shower I'd have before going to bed (or after coming back from the gym) so, again, no increase in the number of showers in a day.
