Huh. In all my years of piddling in the shower, I never encountered a problem with escaping “sewer gases”. The only time I notice a hint of nitrogenous vapors is occasionally during micturition itself, say, in an especially hot shower after a day of working out.
Everybody assumes that all the urine goes straight down the drain. I think this is completely false. I bet that if you pee regularly in the shower and then invite Gil Grissom and the CSI squad to check out your shower/tub, they’d be disgusted. Armed with the special lights and sprays and whatnot, they’d reveal a terrifying amount of pee-splash on the tiles, the soap dish, the shower curtain, the bottle of conditioner perched in the corner, your wife’s hair brush, etc. Even if you aim carefully, there’s just gotta be some residue flying around somewhere (less so for women, I guess, but even then…).
Yeah, I don’t know if it’s true, but have heard the same. My husband and I both freely admit to peeing in the shower. We’ve both been athlete’s foot-free since we started doing so.
Never. That’s why I have a toilet.
SmithWife has some pretty serious objections to me peeing in the shower. Not that that stops me! 
I posted about this a couple years ago, but the thread seems to have vanished. How strange.
Oh my effin’ word! I am just SO thankful I was not taking a drink of coffee when I read this , or YOU, my friend, would owe me a monitor! As it is , I only went into a coughing fit and hacked up a lung.
Funniest visual I have had in a very long time.
Female checking in. Yup. I’m not sure if hubby does or not, but he’s never expressed any objections to it, and he’s not the delicate type anyway.
I’d bet that small traces of urine would be the least disgusting thing they’d find.
Seriously. As the athelete’s foot sufferers have noted above, if anything, urine is going to act as a mild disinfectant. There’s really nothing especially filthy about a healthy human’s urine. Sure, it can be stinky, but it’s not laden with pathogens, and creepy crawlies don’t find it an especially hospitible environment. Look at all the mildew you have to scrub out of the grout. It sure as hell ain’t urine it’s growing in.
Every morning. It’s the first thing I do when I get in the shower. Hubby does it, too. Hell, if we shower together, we just give each other warning so we’re not peeing on each other’s feet.
Following that logic, we should finish the shower and then pee in the shower. Give the tub, tiles and soap dish a good hosing down so they don’t have to be cleaned as often.
Anyway, most residue (urine-based or otherwise) is removed during regular cleaning. I still maintain, however, that a CSI squad would find a surprising amount of pee-splash, for example, high up the shower curtain.
Yup, alla time. Sweetie does as well. Even been known to happen when we’re both in the shower (as long as the pee-er is at the drain end).
Well, no, because when urea and some other urine components break down, it stinks. Unless you can get some lemon-scented urine to splash around the tub, it’s not practial. All I’m saying is having some piddle here and there in highly diluted form isn’t a big deal, and could even have some minor acute benefits.
Only in my own shower, only when actually taking a shower, and only when alone.
And early in the shower so there’s a lot of water running down to clear the trap.
And I sing when I do it.
“I’m peeeeeeeeing!!!”
This is my cutoff. I won’t step into the shower if I already have to pee, I’ll use the toilet first. I won’t step out of the shower to pee, though, if the urge arises while I’m in there.
No! No peeing in the shower!
Of course, one small part of the reason is that my shower drain is clogged a tad, so it takes the water backs up just a bit near the drain.
I do. It’s the only time I can pee standing up. It’s a power* thing. 
- not really, but it’s fun to say it is. it does feel good to pee in the shower, though
Man! You must go like a racehorse!
In the shower people wash the clefts of their anus, vaginal clefts, bacteria laden underarms and crotches, plaque laden mouths & dead skin cells off your tongue (if you brush) etc. Somehow I think urine is among the least disgusting things you might find in a shower “U bend”
I loved Seven’s answer.
I do rarely. Generally if you have to go you know before you step in and do it in the toilet. But if the need strikes, I’d rather do it in the shower than get more water on the floor to get to the toilet. Sometimes the smell bothers me if I do it in the shower.
I’ve heard that there’s a direct correlation between how high a man can pee and the likelihood that he’ll develop prostate cancer. The greater the height achieved, the less likely he’ll get cancer. If it’s just dribblin’ out when you aim for the ceiling, head to the doctor. (I have no cites, and I heard this in a bar, so take it for what it’s worth. The guy who made the statement also claimed to have seen a human hand that was cut off by a thief to get a diamond ring, so, really…FWIW…).
Still, seems like the shower would be a good place to take a regular test, rather than, say, the kitchen or bedroom.
