It's probably the soap chemically eroding it.
Geologically, water erosion happens by carrying away loose material. Solid material carried by the water can abrade other materials to loosen it and be carried away in turn.
If the concrete was properly cured, I doubt pure water would do much. Concrete structures stay submerged in water for centuries.
Your Honor, may it please the court that if opposing counsel says “guns kill people” one more time, my client will shoot them with a gun and they will, coincidentally, die.
As the other fellow said, it is how it is in the video referenced.

Anyway, thank you, I tried my best with the gun cocking sound
It's both.
Chemicals (including the slightly acid water from normal autolysis) soften the water, then the flow moves away the loosened parts.
You can also see this on downspout drains, which don't have soap in them ever. They do have decaying leaves and whatnot in the gutters usually, so it may be even more acidic.
In either case, it would be chemicals \*in\* the water that do the eroding.
In this case I really don't think it's the water, because you can see that directly under the spout it's least eroded, where the water would wash away the soap the quickest. In a ring around the faucet it's more eroded where the soap would linger longer and attack the cement.
You can also see that the side of the drain near the soap dispenser is *much* more eroded than the symmetrical part on the other side of the faucet.
Pure water is also corrosive/erosive, especially because it interacts with air, Buuuut good catch. The soap area is much bigger than the water.
Water is a chemical in and of itself that constantly has a small portion of it losing a hydrogen, then regaining it shortle after.
I dunno, there's a very distinct difference in my driveway between the portion exposed to rain and the portion covered by an overhang. Lots of exposed aggregate and rough surfaces. I think the water just slowly erodes the cement in the concrete
I would say it’s more of the force of the water as it hits against the concrete it takes some of the concrete away very tiny so u don’t notice till later
Yup, concrete is surprisingly week against all kinds of things. Onions, tomatoes, garlic, sugar, alcohols.
Source - Me. I fix floors at food mfg facilities.
They probably sealed it with something hydrophobic and the soap is probably washing it away, then decreasing surface tension and allowing the water and soap mix to soak in and chemically erode it.
It's also likely that the chlorine and other treatments to the water react with the concrete. I have a very very slow drip leak in my basement (like 1 drip per hour) and it's slowly eroded the concrete floor. No soap.
Very slightly acidic water can do this, over a long period. Wherever water drips off my roof onto concrete, it looks like this. We're known to have slightly acidic rainfall here. It's a consideration when choosing pipes for the household water supply.
Water is a weak acid. It does more than just carry away loose material. However it's a pretty slow process.
* Limestone and Marble Erosion: Limestone and marble, both composed primarily of calcium carbonate, are particularly susceptible to erosion by acidic water. The acid reacts with calcium carbonate, leading to chemical dissolution. This process is vividly demonstrated in karst landscapes, where acidified water has created features such as caves, sinkholes, and underground streams.
* Sandstone Erosion: Sandstone, being relatively softer and more porous, can also be eroded by water action. Over time, the binding material that holds the sand grains together can be washed away, leading to the gradual disintegration of the rock.
* Granite Erosion: Even harder rocks like granite can be eroded by water, although at a much slower rate. Granite erosion typically occurs due to the physical force of water combined with chemical weathering, where minerals within the granite alter to clays and dissolve away with continued water exposure.
* Concrete Corrosion: Concrete, widely used in construction, can erode over time when exposed to water containing acids or aggressive salts. The chemical interaction leads to the leaching of calcium hydroxide from concrete, weakening its structural integrity. This is a common issue in structures exposed to seawater or deicing salts.
* Riverbed and Coastal Erosion: Natural water bodies like rivers and oceans demonstrate the power of water in shaping geological and man-made structures. River water continuously erodes their banks and beds, particularly in softer sediments, but over time even hard rock can be worn down or broken apart. Coastal erosion affects both rock formations and concrete structures like piers and seawalls, often exacerbated by the saline environment and the physical impact of waves.
Well Much harder to clean to “a clean bathroom in my house” levels of clean (concrete is too pourous)
But Easy to clean to “a clean bathroom at the park” level of clean
Made out of a different material. Concrete or any porous stone is a no go for anything restaurant/bathroom. That and it looks like this in less than a 2 or 3 years.
The concrete was probably too wet when it was poured into the form. That tends to leave a thin layer of fine aggregates that doesn't bond to course aggregates after curing. That thin layer can flake off easily or wash away with the water.
I stayed in a hotel in Japan in a place called hell valley. (noboribetsu japan) and they had a marble sink that was the same but much much worse. The water basically had bored into the marble. I didn't take a picture for some reason.
The guy who owned the house before me put in stupid home made concrete counter tops, and you can see where we have accidentally left wet glasses before by the sink.
Wtf, I knew homes where the laundry sink was made from concrete, and the products used there where even harsher than just soap water, and in no way the concrete was eroded like this. I vote in shitty concrete.
I hate sinks like that. They always splash on my pants and make look like I’ve pissed myself. Walking out of the bathroom with water all over your crotch area is fucking humiliating
Ive heard acid will erode a kitchen contrete counter. So you really have to be careful not to get tomato juice and stuff like that on it. Not surprised a sink has eroded by either soap or whatever people washed off their hands.
I'm think maybe reverse osmosis or DI water would cause minerals in the concrete to be absorbed? Would be interesting if someone educated in the topic could stop by though.
Mf will unironically look at that and say: now imagine what water does to your gut
Never touch the stuff... fish fuck in it you know.
r/UnexpedctedArcher
This joke was around waaaaay before Archer
Do you want old jokes? Because that's how you get old jokes
These are dark times.
Not even joking I just saw a guy on ig today who is literally promoting the idea that you aren’t supposed to drink water, dead fucking serious
Do not, my friends become addicted to water, it will take hold of you and you will resent its absence.
A cautionary tale for sure
Well, dihydrogen monoxide is the cause of over 1 million deaths each year.... So.....
that’s my kink
Enemas?
You can literally see it more eroded in the soap dispensers. The visible stones are larger, more surface area visible
Everyone who has drank water dies.
100% of the people that consume Dihydrogen monoxide die.
Dihydrogen monoxide is an INDUSTRIAL CHEMICAL!!!!!1!
Better check that statistic again, I know roughly 8 billion people who've consumed it and aren't dead.
Yet.
So you don't in fact know that 100% of people who consume H2O die
According to Murphy, eventually.
[Water is horrible for you](https://youtu.be/e-lxD8RhxSw?si=ehUuv-g47gKKj704)
Have you heard of dihydrogen monoxide? It accelerates corrosion and causes suffocation. Can't believe it hasn't been banned or regulated.
Everybody who has ever drank water is either dead or will be dead!
100% of people who have died have water in their system when they pass. If it ain’t the water, it’s the air that will get ya.
100% of people who drink water, die.
This comment reminded me of the world we live in and my day is ruined.
Just drink your potion, Seluvis, and it will fix your day in a sec
Looks to me like it’s sinking.
What do you think it’s sinking about?
The German Navy.
Other sinks
Let that sink in.
Really circling the drain with that one.
I’m plumb out of plumbing puns.
I'm going to level with you that was kinda lame
Tell us what you really sink
These puns are so watered down

What are you basin that on?
This may be a multi fauceted question.
I feel drained thinking about it.
Lol, is that real? I hadn't seen it.
It's from the movie, "Hitch."
Oh, I just figured I would've seen that after Will Smith challenged Chris Rock to a duel. I guess I missed it.
It's worth watching if you happen to see it playing. Nothing special, but not terrible. It's fine.
Sinks gotta sink
Sink again

running water erodes concrete regardless of how well it's cured submerged concrete and concrete under running water are not the same
It's both. Chemicals (including the slightly acid water from normal autolysis) soften the water, then the flow moves away the loosened parts.

Also tap water isn't really pure water. There are a lot of minerals in it that play a role as well.
Yes, you can see that on both sides the worst area is under the soap dispenser.

Maybe these restaurant patrons just have _really_ dirty hands and their hand runoff is what eroded the concrete. 😬
Yes, concrete structures stay submerged for centuries but in this case the splash from the water can also erode concrete.
Cavitation can do it
They probably sealed it with something hydrophobic and the soap is probably washing it away, then decreasing surface tension and allowing the water and soap mix to soak in and chemically erode it.
Sulphates attack concrete pretty badly over time
Like a pool?

Thanks, brand new information.
Dat's why you coat stuff with stuff that water won't erode. They forgot to coat it.
where is the drain?
You can see it along the back edge there.
I can't, but I'll take your word for it because nothing else makes sense.
> can see it along the back edg It's a downward cut across the entire back. The white soap is sitting in it.
Have people never seen one of these sinks? Theyre not common, but they’re out there
Honestly at least here in the US they're pretty common, especially in places like movie theaters, airports, stadiums, even a lot of restaurants.
Answered your own question there, if they aren't common, no a lot have not seem this kind of sink.
I’ve only seen them at like fancy restaurants.
theres a drain or vent in the bottom of that cut? where the white bubbles are?
Yes.
thanks for asking the real question.
It’ll be the Grand Canyon II in a million years. Keep the water flowin’.
Soapy water eats away at concrete. It's not just water erosion.
I bet most right handed people use the sink on the right by default (unless it's already occupied) and the lefties use the one on the left.
Or that side is closest to the doors or the hand dryers / towel dispenser
Right-handed people use this toilet, because the door is on the right, but left-handed people use the other toilet, because the door is on the left.
I'm left handed yet use right sided things all the time.
I'm right handed and just wrote this whole comment left handed.
Yea I'm right hand dominant for most everything & yet I write left handedly... Type mostly right handedly... I'm... I'm not normal.
I wrote this comment using my foot. My left foot.
Weird I actually read that with my feet
The right side is probably closer to the urinals/toilets.
Probably is easier to clean and maintain and it looks rad. Even eroded
Well Much harder to clean to “a clean bathroom in my house” levels of clean (concrete is too pourous) But Easy to clean to “a clean bathroom at the park” level of clean
This is concrete evidence that the erosion of the sink is not set in stone.
r/angryupvote
the most interesting thing in this picture (to me) is the river rock type aggregate they used
Looks like a shit job from the start. I work in custom masonry and stone commercial and home projects.
What should it look like? (Besides not eroded.)
Made out of a different material. Concrete or any porous stone is a no go for anything restaurant/bathroom. That and it looks like this in less than a 2 or 3 years.
how are we going to fix it, its not like we have air water sand and gravel just growing on trees ya know
>and it looks like this in less than a 2 or 3 years. I kinda assume that it was intended to look like this.
Agreed. Concrete like that should’ve been sealed at the minimum
At first glance I thought this was posted to /r/Concrete as a customer complaint.
You’re fucking kidding me, it’s real. Of course there would be a concrete subreddit.
If the bathroom sink is getting worn out... I would be happy! Atleast people are washing their hands 😂
“ERODING BENEATH ME!!!”
It's not hard to sink a restaurant, the age of the concrete suggests it's a decent place to eat.
The concrete was probably too wet when it was poured into the form. That tends to leave a thin layer of fine aggregates that doesn't bond to course aggregates after curing. That thin layer can flake off easily or wash away with the water.
This is rlly cool!! I would get a concrete sink for this feature!
The feature of it degrading after some time?
Yeah! I did think referring to it as a ‘feature’ is an odd word choice but I thought oh well I just wanna get my point across :)
It’s just exposing the aggregate?
This is the German Coastguard, What are you sinking about?
Tsk tsk. Shouldn't have poured that coke on it.
I stayed in a hotel in Japan in a place called hell valley. (noboribetsu japan) and they had a marble sink that was the same but much much worse. The water basically had bored into the marble. I didn't take a picture for some reason.

You should put beeswax on untreated concrete.

That'll do it hahaha
Now imagine what water does to your stomach
Our Cheesecake Factory has one of those
Wtf, I knew homes where the laundry sink was made from concrete, and the products used there where even harsher than just soap water, and in no way the concrete was eroded like this. I vote in shitty concrete.

Pink hand soap is actually very acidic
OMFG!!! THIS IS WHAT **DIHYDROGEN MONOXIDE** DOES!
Ahhhhh…. Restaurant restroom… that wouldn’t be ideal for food prep or cleanup.
Is it that it’s eroded? Or is it slanted like that so there’s proper drainage??
The cement is being eroded away from around the aggregate in the concrete. The slope is, as you suggested, for drainage
I hate sinks like that. They always splash on my pants and make look like I’ve pissed myself. Walking out of the bathroom with water all over your crotch area is fucking humiliating
W H A T

It’s a feature…..
Idiot me thought this sink was for the kitchen
54th street?
Correct!
San Antonio?
Not correct haha one in Kansas City
One of the locations here in San Antonio has the same sink with a similar wear pattern, it looked familiar
Oh damn I saw the picture and thought I’ve seen one just like that. And then you are in KC ha.
There’s one like this at the secret stash up in Crested Butte. It’s the weirdest sink I’ve seen and I don’t like it.
That's part of the appeal, for sure
Looks like moctezumas in washington.
It’s not a style choice? Exposed aggregate costs extra
The poor man’s exposed aggragate
Customers have been licking the sink
Probably not sanitary
Well, if you are eating your food in the sink... No
And….
Nice comment 👍
Comes with time label to change
I've seen this before. Severe concrete deficiency in the water supply is my professional opinion.
Took me ages to realise this isn’t in the kitchen and therefore wildly impractical.
Lolinda in sf?
The right sink must be closer to the women’s stalls
Would that be from water hardness?
I'm think maybe reverse osmosis or DI water would cause minerals in the concrete to be absorbed? Would be interesting if someone educated in the topic could stop by though.
