I’ve been cleaning things most of my life. I’m kinda anal about it. I know, I know. Life’s too short to sit around organizing junk drawers and straightening out closets and pantries. It’s my hobby. I know it’s sad. Don’t cry for me, coz dusting makes me happy.  
So bathroom cleanliness speaks right to my heart. Not to mention my germ issues. I love, love trying new bathroom cleaning substances. I fall back on bleach, though. My go to. I buy bleach every week. Drives people insane. But, dang it, my bathrooms are so clean you can eat you dinner in there.  
You won’t be smellin’ pee in my toilets not as long as I’m able to get to 'em. Ain’t no yellow gonna mellow. That’s why that little handle is there, use it!

We have flushless urinals in our office. They have to be cleaned at least a few times a day, which I suspect negates much of the water savings. They do tend to get clogged up.

If you consider “environmentally friendly” to include all forces external to you (including your spouse), I’d say, “No.”

> We have those at many of our buildings in the state. They have signs over them saying 40,000 gallons of fresh water saved a year, and it’s easy to believe that they save quite a bit. Not sure why, especially here in the south west, everyone doesn’t go to these things. There must be a reason, but I’m not seeing it. It saves water AND must save money too, so why not adopt them or put them in when the old ones go bad?

I had to clean drains from urinals with water flowing through them. The salt builds up can close off a 1 1/2" drain. It is real nasty to try and clean them out (hate urinals). I would hate t work in a building that waterless urinals had been added. I bet they are not cleaning out the drain lines but having to replace them. I may be wrong but I can only imanage.

What about normal urinals? Don’t they use a lot less water, and thus still save water vs. a toilet?

I’ve actually only seen those waterless urinals (which were also at or below the the floor) in older, dingier places. I assumed they were an old practice not used anymore. Then again, I live in an area that always has plenty of water available.

Probably not.

But your sink drain isnt designed for urine. The ones on a waterless urinal are.

Better to urinate in the toilet and not flush.

Or in your backyard, keep the mtn lions out, so they say. 😛

Yes, and you have hover-ers and those that MUST flush their napkins/tampons, which causes a _nasty_ plug.

Women are better in their own bathroom , but in a public restroom, the womans is always nastier.

Yes. it certainly cant stand overnite or anything. So, when you defecate of course you will flush, and maybe flush urine once in a while. But that still saves several flushes a day.

Pumping water and cleaning it does use energy, so even if lots of water, there is a cost.

Yeah, living in the country, if I’m outside doing something I _never_ go inside to pee. Never seen a lion, mountain or otherwise.

What makes you say that urine mist won’t be all around the sink? I suppose if you can make the stream go exactly into the sink drain it’s okay. But with most bathroom sinks having a drain stopper, that wouldn’t be possible. If the stream is hitting the sink, then urine will be splashing all around the inside of the sink and mist will be landing outside the sink.

If anyone really wants to check, pee in the sink and use a blacklight to see if any urine is left behind.

Consumer Reports recommends that households with men instill a regular, flush urinal if there’s room in the bathroom, because it saves water. Other than the space it takes, I see no downside to that.

It’s a terrible, debilitating condition (;)), and as a consequence I honestly don’t know if urine in the bowl leaves a lingering odor that will fill the room. Has anyone ever experimented with that, preferably in a controlled study? Even if the answer is that yes in fact it does stink up the room, is that still a better choice than putting one’s… “fireman” on the counter to piss into a sink?

Yes, it smells. My husband doesn’t always flush if he only peed. I agree that if it’s fresh, it’s not too bad. In the morning, when we often use the toilet right after each other, I don’t mind if he hasn’t flushed. But if he goes at night, and I use the toilet in the morning, I find it unpleasant.

We live in the damp northeast, so I don’t try very hard to save water, unless it’s been a dry summer.

Again, it is not just saving water, it saves electricity and other resources.

It’s the distance. When you urinate in the sink, there is a very short distance.

I actually put the end of Mr Happy right into the drain, so distance = 0.

Sure, although I suspect the cost of treating the sewage is greater than the cost of shipping the water to me. At least, they charge a lot more for that.

But if you accept that the resource cost of stuff is at least loosely related to the dollar cost of the stuff, water is really cheap. Our water is local, by the way. Some comes from wells and some from an aquaduct that flows downhill from a short drive away. And since most of the cost is electricity and such, I don’t think that’s being weirdly subsidized. And the water itself is a renewable resource: every day the sun sucks it up from the oceans and drops it back down into the aquifer.

I’d probably save more energy by shopping less often (fewer trips) than by not flushing pee down the toilet. And leaving the pee to ripen is gross. Water is pretty low on my “resources I try not to waste” list. I’d treat it differently if i lived in CA or some other desert.

# Holy Moly! I did a little calculation: 330 million Americans times 0.5 male times 0.5 receptive to environmental concerns times 4 pees a day times 1.5 gallons per flush times 365 days a year

181 BILLION gallons of water saved per year. We can’t afford NOT to pee in the sink!
