I understand but how would water come from overflow when there is no water being ran.
Con-den-say-shun maybe.

This why I asked the questions I asked that seems to have gone over everyone's heads and remains unanswered by the OP.

Don't you love it when the OP asks a question and everyone kicks in their 2 cents(no matter how far out in left field they are) but the OP is AOL- lol

if he hasn't used it than it should be room temp before it starts to condense, that's why i am thinking that it's an angle stop.

And that is exactly why I (and you may have noticed this) almost always ask a question or two before I waste a lot of my time spilling my guts for someone that may never return or never give a damn about my effort. I ask questions and wait for them to respond. If they are interested they will be back in a few hours, if they are flying-by never intending to return then I haven't wasted a lot of my time.

I get a kick out of the threads that go viral with scores of speculative BS with only five words from the OP in the very first post. Some of the evergreen threads just amaze me at how gullible some participants can be, and for what. Just to see their name on the Internet I guess.

My vanity sink is "sweating"


Dear Bud, plumbing, TheEplumber and oh Mike,
Thank you all for your ideas and suggestions. You are right, nobody used the bathroom and the sink was wet in the afternoon. The sink is a Villeroi & Bosh sink and the first thing I have done last week is to change the drain pipe supposing that there may be some leak at the joint underneath the sink. This did not help. Taking into account that the sink was not used and no change in environmental temperature has ocurred, I discard the possibility of condensation.
Regards to all

Bernard

Post a picture of the sink---and let us know what material it is made of--also the under cabinet piping.

Bernie....you discount the possibility of condensation but in your original post you say the sink is sweating. If you take a shower in morning or at nite, the warm moist air will still linger long after showers are completed and will eventually find a cooler surface to condense onto. And you do say there is no exhaust fan. Even though you cannot sense no change in environmental temperature, the humidity is still there after a shower.

Is the underneath of the sink inside the vanity or is this one of the sinks that surface mount and the underside of the sink is actually on top the vanity? LIke photo below?

Also is this bathroom on 2nd floor? Is kitchen underneath?

Do you have a range vent hood in kitchen not be properly vented to outside and into a joist cavity and traveling into bath wall area?

Like Mike mentioned a couple pics might assist.

Just my 2 cents.

Thanks Hammerlane

Here I am attaching a picture of the sink which is underneath the vanity.
As I previously said, I did dry out completely the sink in the morning and took a shower in my other bathroom. Nevertheless at approximately 05:00 PM the sink was wet and nobody has used it that day. We have a skylight in the bathroom but it is closed. Only light goes in from the roof (I live in the last floor of this building [8th.]).
Have a nice weekend all of you and thanks again.

Like I said...
It's a porcelain sink and those things can experience condensation on a regular basis. There are other questions to be answered also but the OP hasn't bothered.

Looks like a definite humidity issue.
How long has this been occurring?
Has this only started happening since the weather has gotten cooler?
Did this occur in the summer/fall when weather was warmer?
Besides the skylight, are there glass windows in this bathroom and do they have condensation on them?

My vanity sink is "sweating"


Dear Hammerline and Bud Cline

Even though the weather here is entering into the cold part of the year, this "sweating" has occurred during the last 2 weeks. Lets suppose that it is "condensayshun" could I maybe coat the sink with some material (paint / coating) to isolate the coolness of the sink and preventing the hot air to condense? Just an idea which may be a solution to such enoying problem. The bath room has no windows and has a huge mirror which is dry (!) when the bathroom is not used. It is only wet during and after we take a shower and just for some 10 minutes after the shower.
Have a nice Sunday!! Thanks in advance.

Anything you can do to provide a thermal break between the surface of the sink and the air will help. Maybe some sort of spray on rustproofing material?

Try this first. If you have a space heater, place it in the middle of the bathroom and open vanity doors. Leave it on about 1/2 hour before you start your shower to 2 hours after the shower is done. If this rise in air temperature prevents further water on underside of sink you will kind of know its a humidity problem.

Stainless steel kitchen sinks have a terrible condensation problem for some reason and a lot of them (most of them) today come with a thermal break painted on to the bottom of each well. It looks to me like the same product used to spray-coat (undercoat) automobiles or maybe truck bed liners. Maybe that would help maybe it wouldn't.

From Post number 2: (Post #2 mind you)

Porcelain sink?
CHECK - Got that right.

Forced-air heat probably propane?
Still no response from OP.

No ventilation or exhaust fan?
CHECK - Got that right.

Maybe everyone is overlooking the obvious.

I am sorry in advance, but I keep reading this thread and I am mystified, which as Bud can attest to, doesn't take much!

Heard on the national news a few days ago that some golden colored heavy liquid has begun dripping/running down the inside wall of a church for several days now. One inquisitive sole decided to taste the liquid and said it tasted like honey.

The minister of the church said that it was not honey but instead it was obviously a message from God.

I wonder how many snakes he has.
