Let him smell! There is really no health reason of taking each day a shower. A healthy body can deal with the layer of bacteria on the skin very well, some the bacteria have even benefits in keeping the bad ones out.
Leave him!
I disagree with this because if showers are not a part of your daily routine then they become harder and harder to do... and the less you do them the less likely you are to get used to them.
Teenage boys develop body odor quickly. I may have lasted relatively well into my adult years, but I'm female. A boy would have been much more obviously unwashed... Also remember there are people with sensitivity to smell who would be very overwhelmed by your boy's BO. I'm one of them. (I get overwhelmed by perfume, cologne, or hair spray smells too, so it's not just the "eeww, gross" reaction.)
Anything is easier when it is a part of a routine, when everything is expected, instead of sprung on you.
I didn't shower regularly until I was about nineteen. I think it was 19, anyhow; I remember carefully putting together an every-other-day schedule that year. It helped to develop a list of things to do that was the same thing every time.
I don't know how routine-dependent your kid is, but if he is, then this may help, because if you need routines it's likely you need them for a reason--that is, using them helps you think and plan and cope with things.
Today, I get up, make my bed, shower, dress, feed the cats, and clean the litter boxes in twenty minutes. That's all thanks to routines. Other chores still take a long time, but that's only because I haven't got good routines for them yet.
Alternatives to daily showers: Sponge-baths--that is, wash your hair, armpits and groin at a sink--which don't envelop you in water the way a shower or bath does, but isn't as thorough. Or showers every other day--but always on a schedule, so that they cannot be easily put off or ignored.
Does your boy wear a buzz cut? If not, and he can tolerate clippers, consider it. It doesn't take nearly as long to wash very short hair. Have him wash the bits of hair off in the shower afterward so it doesn't tickle his skin.
Keep the bathroom warm--80 degrees at least. Put a space heater in there if you have to. There's less contrast between hot water and cold air that way.
