I just got out of "shower jail" after being home for a week after a knee replacement. Besides the relief of being able to take a shower today, I HATED shaving at the sink. First, it takes twice as long as shaving in the shower with all of the "hand"-rinsing between each pass. You have to constantly bend over at the waist to keep the water off the floor, (As well, after a knee replacement you can't risk getting the site wet) so your back is aching the whole time. (I also have lower back injuries) So much easier to shave standing fully erect, where a full rinse consists of simply moving your head under the shower head for a few seconds. Bonus, you get to wash another towel with each shave. Usually takes me about 20 minutes to shave in the shower, and about 35 at the sink. Apparently, having the hot water washing over you helps with the shave, too, because my "sink" shave was never as smooth. Just my two cents.
