Where to find old stuff (sink) for new apartment?

Demolition Depot on East 125th Street. I know there is also a place in Stamford, CT like this- but I can't recall the name.

Olde Good Things has a Manhattan store, but the big salvage pieces are usually in Scranton.

Absolutely check out Build it Green (LIC or Gowanus). Amazing stuff. They just got in a huge shipment of things from demolished landmark buildings in NYC.

Sorry, missed that you'd been there.

@Semerun - YES! I know Demolition Depot...don't know why I didn't think of it. Will google for Stamford place...seems like a good corner of the world to start.
@West81st - thanks!
@emma63 - It's such a cool place, the tip bears repeating. Haven't been to the Gowanus place - excited to check it out.

Google is your friend, I picked up a huge batch of vintage tiles years ago from a place in Barnegat, NJ that I found on the Interweb.

Or, frequent estate OHs on the Upper West Side and make them offers when you see sinks in-situ. I've seen at least 2 in the last 12 months that ARE going to end up in the dumpster.

You mean like this kind of thing?:

@nyc10023 - Yes, google and I are the best of friends. Not sure I have the strength to go prospecting at OHs but, such a good tip for the more tenacious.

@bramstar - Yes, like that. I've been on that site and others (Kohler has a nice one, too! http://www.flickr.com/photos/kohlerco/5526568905/in/photostream)... but they are a bit pricey, to be honest. I was hoping to find a 'find' if you know what I mean. But oh, well.
Maybe it's not the worth the hunt 'n' haul, in the end...?

Well keep in mind that a true vintage piece may come with flaws that need repair and that could ratchet up the final cost... You may also find that unless you are able to score something from a construction site or a dumpster that the prices are comparable if not higher at places like Demo Depot.

I was just out at the Build It Greens in Astoria and Gowanus. Lots of good stuff.

Astoria had a whole set of yellow St. Charles steel cabinets, from what must've been a huge kitchen, but a lot was sold already.

As bramstar said, a lot of the cabinetry was expensive custom stuff, made to fit, so would take some finagling to adapt.

Did you try Moon River Chattel? They have a lot of salvaged fixtures. http://moonriverchattel.com/Moon_River_Chattel/Moon_River_Chattel.html

Or craigslist...

Check with the super in your building, often they have a collection underneath in the basement.

Often when these items like nyc10023 suggests are going to end up in the dumpster, i.e. a new renovation in an apt the super will then store them downstairs in case another owner wants it.
My friend at the Majestic (115 CPW) told me when one of her glass legs broke to her sink vanity, she checked with the super and he had a stack of them.

Another friend ordered a pair from Demolition Depot....disaster $2500, then only 1 of the 2 legs arrived, yet because she had signed for the package without checking the contents, Demolition Demo wouldn't honor that they only put in 1 leg. Be careful of Demolition Depot I have heard too many bad stories.

Additionally in my old building when I had gone thru the really tough choice of renovating and taking out the beautiful old original tile (there were few too many cracked tiles for me to live with). I got my guys to slowly demo out the tiles without damaging them, yes it took an extra 3 days, for 3 bathrooms however I ended up with boxes of good original tiles to give to the super. So that if someone wanted to keep the original tile yet needed to replace the shower body etc they had a stock downstairs for small jobs.

This would work especially well since you already like the style of the sink.

Otherwise I have done great with Ebay, put in searches like "vintage sink", antique sink or if you know an old brand you like, I personally love the old crane sinks.
