Have you looked into 'bar' sinks? Ask your local sink supplier (HD, Lowe's, etc) about them.

Architectural salvage or plumbing supply stores that specialize in vintage plumbing would be the first 2 places I'd check. I've seen tons of very small, very good condition sinks in salvage stores. Are those options for where you live?

I've seen some pretty small sinks in Renovators Supply catalog - but I can't recall if they were wall or pedastal or both... they have a website too.

Renovator's Supply usually has some very small porcelain sinks.

go to plumbingsupply.com and check out "handwashing sinks" "classroom sinks"... there are some that have a depth of 6 inches! I had a similar problem with a door clearing a sink, and I decided to move the wall back to accomodate normal size sink (and make the room bigger), but that means a lot more work....

Posting a pic of existing conditions would be helpful...
I have a PR - that is 3.5' x 3.5' - and had NO sink! was a jon closet - I think PO cut in a new back entrance, left toilet & removed the sink -
In any case I searched high/low - and found an American Standard tiny corner sink & managed to fit it in, clearances & all!

Have you thought about going a different direction and getting the sink re-glazed. If you can do it to a tub why not a sink? I'd think it be cheaper and you'd have the benefit of knowing it fits the space.

Only can think of this one right off the bat, but i know I've seen one or two in the bathroom forum of similar small offset(?) sinks. {{!gwi}}

You could consider recessing the sink into the wall, or putting the faucets on one side, as in the picture above.
Check the dimensions of a corner sink, it might fit.
and there are toilets which have a sink built into the tank.

Could you swing the door out, so it doesn't interfere?

Be very careful with the small sink shown above (Tina from Clawfoot Supply). I have the Rosanna (which is even smaller than the Tina). Barclay is the distributor.

What they don't tell you is that the deck of the sink is so small, the only faucet that will fit is the clunky modern one shown in the picture of the sink. I tried hard to find a faucet that was a better style fit and couldn't find one - I have a Grohe that looks just like the faucet in the sink pic and is at least a known brand. Barclay customer service is useless; although you can find some dimensions online, they couldn't give me the critical dimensions.

The sinks are recast from old molds (from the 1800's, I think) and are meant to have 2 separate basin taps for hot and cold water. If you turn the sink over you can see the impression where the left hole was not knocked out.

Corner mounts are available from Renovators SUpply in a couple of styles.
They are about as compact as you can usually get for very small bathrooms.

If you have a sink designed for double faucets, Renovators also has sets that use flex tubing to connect the valves to a single faucet.
The faucet goes in the pop up drain hole in the middle.
They are often refered to as 'variable spacing' sets.

First of all, I heartily apologize for not responding earlier - just got a little busy and you've all given me wonderful links to pursue. Some of those glass sinks are really cool but stand on a base that's a bit too big, darn it - bigger than necessary, it would seem.

penfolddt, I'd seen that sink before and it's on my list of possibilities. It just seems strange to me that my sink actually looks "normal" sized to me but still projects from the wall less than any "mini" sink I've seen online. Sacrificing width might do the trick though. I haven't found one sink that has the diagonally edged corners that mine has; it's the only reason the sink currently works in this room.

I'll try to post a picture tomorrow of the sink/bathroom. I hadn't considered re-glazing it, though maybe I should. But then I'd also need new faucets for it. The hot water leaks now and the sink is seriously stained from years of leaking AND has a crack in it. I'd really rather get a new one if possible than pay for re-glazing, and trying to find the vertical faucets for it. I am probably going to get my upstairs bathtub reglazed though, so if anyone has any experience with that, I'd love to hear if you were satisfied. That bathroom isn't much bigger than this one and I don't think I could get a new bathtub in there without breaking down a wall.

I don't really have a corner I could mount a corner sink in without totally configuring the bathroom. One corner has a pipe going up to the second floor, the toilet is pretty much against the other corner and of course the door rules out the front two corners. I know lots of people with older houses with very small bathrooms; the difference with this one is that the bathroom isn't as deep as some of those, and that the toilet and the sink are on opposite walls. Behind the bathroom is a laundry/utility closet with a double door that opens onto the kitchen so there is SOME possibility for renovation, but no gain in width. Anyway it's not something I'm looking to do unless I hit the lottery or something, LOL. The upstairs bathroom badly needs updating as well and since it's the main bathroom, that would come first!

Never thought about swinging the door out at all, interesting idea! I don't have a clue how to go about that, LOL. It would be pretty awkward since the bathroom is opposite the basement door between the LR and kitchen; I guess it's no more awkward than the bathroom as it currently exists though!

I don;t suppose you would want your sink on the back of the toilet, would you? We had these when I lived in Japan and they are GREAT!

Rohl and Duravit both make smallish sinks. Don't have model numbers/names of Rohl, but one is quite narrow. Duravit makes a "1930" model that is wall hung and small.

What about architectural salvage? Tiny old sinks like you need are sometimes called "cloakroom sinks" in the salvage yards. If there are no salvage companies in your area, try posting a request on SalvageWeb. eBay is a possibility, too.

Maybe an old "spit sink" (aka a "toothbrushing sink") might work, too. See the recent thread "1940's bathroom- what is this sink thing?"

I don't know what you mean by "vertical faucets", do you mean single basin faucets (looks like this)? Here where I live (eastern NH) a basic chrome version is about twenty bucks each in almost any hardware store (not the big box places). I have never minded them at all, personally, but some people consider them a huge hassle. If you get a two-holer intended for that kind of faucet, you can plug one hole with a hole cap and use a monoblock faucet, or get this ultra-cool pencil neck bridge faucet that adjusts to a wide variety of sizes.

Re: that toilet lid sink - wouldn't you have to replumb to get hot (or at least warm) water over to that faucet or are you stuck washing your hands in freezing-cold water? Brrr!

I just saw an article about another house with the same situation. I think it was in the latest Cottages & Bungalows. I believe they used an old Victorian sink, so you can make it work!

Johnmari, by vertical faucet, I meant one mounted on the back vertical wall of the sink, rather than on top of the ledge...I believe the correct term is shelf back/ledge back faucet, sort of like this: http://www.deabath.com/Original/Or_whs1/Or_whs2/gray_briggs.jpg

Well, I think I've found a couple of options, but it's been surprising how hard it's been because I never thought of my sink as very small, really - just that precise measurements were required. But evidently the projection of my current sink from the wall is much less than standard, and much less than even many "mini" sinks. It's a shame so many of those modern glass bowl sinks sit on such wide/deep pedestals when it seems so unnecessary and many would have worked perfectly otherwise!

I really do have to visit some plumbing supply stores rather than just looking online. But so far, the two most likely candidates seem to be:

(This extends much farther out from the wall than my current sink but is 5" less wide, so I think it wil work)

or

the sink in the link below

I had next to no luck finding a pedestal sink that would work!
