Why Ice in the Urinals?

January 24, 2004 3:31 PM

Why do some restaurants and clubs put ice in the urinals? Is it a smell thing or is it to provide manly entertainment? It seems to up the "splatter factor", so I'm guessing it's benefits aren't mainly hygenic.

I've never heard of such a thing. What restaurants have you been in lately?

My groundless theory has always been that it is to show that the urinals get periodic attention from someone, with the implication that they are being cleaned.

Best answer: There's a discussion of this in The Straight Dope Tells All. The leading theories are:

• The melting ice acts as a slow, continuous flush
• Ice cools the air around the urinal. Cool air sinks, which serves to contain the smell
• Cold discourages drain flies
• Fun to melt, helps users aim better, compensates for poor male sanitary habits

Response by poster: Thanks! That sort of makes sense. My next question: Does this actually work?

If I remember correctly, it's "cheaper" to use ice than toilet cakes. Many bars & clubs will have an ice-making machine linked to one of the water taps; the amount of ice created per gallon would be easier to replentish throughout the course of a business day, whereas toilet cakes would have to be replaced several times in a week.

The cakes often have an odor of their own (cheaper versions use camphor oil, while pricier brands substitute other chemicals), which can become stronger when customers and employees uh, forget to flush. Ice cuts down on the smell, and rinses down the drain with little fuss. Apart from urine, one also has to remember that beer, vomit, and chewing gum are other things which fall into the trap; again, ice does a better job of masking this than camphor.

On preview: what Space Coyote and kirkaracha also said.

Coyote's answer makes the best sense to me. If it's known that heads will roll if that ice has ever melted all away, there's high incentive to check the bathroom cleanliness frequently!

This is my supposition as well. Very few men will bother to actually flush a urinal. That is if the running water even works. Ice is cheap at most restaurants/bars, and more attractive than some soiled cake or plastic sheet.

It's also an input-only system. That is, you never have to remove the plastic cake cage, or the perforated triangle, for cleaning. Just shovel in more ice.

It wasn't until moving to America that I found a urinal you could flush. All the urinals I've used in the UK have either flushed automatically on a timer, or using some form of proximity detector (they flush when you walk away from them).

I only just realised that "flush" is onomatopoeic.

Simple answer. Some sewage systems are not designed to handle constant flushing so they turn off the water to the urinal and use the slowly melting ice to keep a steady stream flowing. Otherwise the sewage backs up onto the floor.

Derail: I am most amused by the plastic triangles that say "Your ad here!".

After reading the FPP about prostitution, stbalbach makes sense.

That, and the ice is too damn cold. A fellow could get shrinky-dink!

We have plenty automatic-flushers here in New York City, and not a one could be flushed during the blackout. The auto-flushers need to not rely on electricity, but instead have some sort of water-fed clockworks to do the job.
