I can go every other day.
When I was younger my cousin and I would have contests over Christmas break to see who could go longest without showering. I lasted a week. I think she lasted a little longer. Yes, we were a couple of scuzz buckets. :D
I shower every other day or when I remember. lol I don't get really sweaty or stinky or anything like that, so you can't tell.
Depends on my hair.
Up to two weeks. But I wash up in between full on showers. I hate full showers because my hair takes so long to dry. x.x Besides, I never leave my room, so meh. xD
I have to shower at LEAST every other day. Maybe I could go two days, max. I just feel disgusting and dirty if I don't shower. I shower two or three times a day when I feel like it. XD
I have gone up to 3 weeks before D: But my hair doesn't get greasy quickly and I don't smell for a while, so I usually shower every three days. :P
Like, 2 weeks, I think. I don't like showers, but I love being clean... but I'm lazy so yeah I usually just deal with the nastiness until I feel like getting up off my lazy, dirty ass and taking a shower xD
4 days ABSOLUTE MAX.
3 days pushing it.
2 days, then I want one.
1 day, when I normally shower, sometimes I'm too lazy though.
It depends on when I showered last. Example: Say I take a shower Monday night and go to sleep. I could go all Tuesday without one. But by mid-Wednesday I'd want to take one lol. I could go two days. But, now that it's summer vacation, and I'm a bum so I don't sweat, it's every other day. During school though, it's everyday.
I wash my hair every other day. It's not too bad on day 2, but yucky by day 3. And washing my hair everyday would kill it.

Pure laziness Vs the need to wash my hair.
Twice a week. Sometimes I'll skip the shower and just wash my hair, and give myself a quick wash down. But I'm also VERY water conscience since returning to the city from living in the country and living ONLY on rain/tank water. However I bath the kids every second day in winter and everyday in summer.
I believe its yellow, let it mellow, if its brown flush it down.
Longest time without a shower- 3 weeks. when I ran out of tank water on the laundry/bathroom side of the house. I thought drinking was more important than washing. I had to wash clothes in the kids bath water.
D: 12 hours. I'm compulsively clean and if I don't shower twice a day I'm very grouchy and irritable, and I feel disgusting.
On schoolyears, every day. I shower whenever I feel like it on summer break. I never really have a time limit, but the longest I can go without being forced to take a shower by my parents is 1-2 weeks.
i can go without showers for a week, it was a dare, and i passed it. got $50 bucks! so yea. but i do shower every dae.
I once went 4 days without showering. I shower every day .
I think about 2 days is the longest I can go before I start to feel real icky.But if it was a matter of endurance I could go about a month :)
The longest I have gone is probably a bit over two weeks. And I like to shower every night before I go to sleep, if I have time.
Probably 2.
I usually only shower every other day. My hair doesn't get greasy until like 3+ days.
I shower every 2 days. That's as long as I can go. Any longer and I'll just look and smell horrible.

I shower every day. I can probably last 2 days without a shower. Longer than that, my hair is disgusting.
At least twice a day.
I couldn't go more than 24 hours without showering.
During the colder months, I shower once or twice a week. In the summer, about once a day, especially now that I'm trying to work out and that makes me feel really gross afterwards.
I dunno, maybe I just don't sweat much and have magical greaseless hair or something? I don't even know how to get gross and smelly after two days, or even after a week o.O;
