Franke has sinks that fit a 33in cabinet:

Oceania (OAX110 and OXX110) is 30 x 19 x 9
EuroPro (GNX110-28) is 28 5/8 x 20 3/4 x 11 3/16
Planar (PPX110309/16, PPX1103012/16) is 31 1/2 x 19 1/2 x 9 or 11 1/2

FWIW, the dimensions above are exterior dimensions. Interior dimensions are about an inch less. If you find something with a similar size, it should fit the 33in base cabinet.

Check this one out. While the outer dimension is 32" to the edge of the flange, it should still easily drop within a 31 1/4 space- the flange would rest on the sides...

I love my ss undermount single bowl sink. It has an overall size of 30" x 18" and it fits in our 30" sink base. The inside dimensions are 28" x 16". It's also a good price for 16 gauge thickness. We had to modify the sink base by notching out the top portion as shown below. After this picture was taken, we notched the other side.

Please help me out, why do you not want a 28" or 29" wide sink? You say you want a nice big main bowl which seems to say you want as big a sink as you can fit in your 33" sink base. The 28" & 29" sinks will easily fit in a 33" sink base. Remember, the flanges fit over the sides of the cabinet so the overall dimensions can be up to approximately 1/2" smaller than the sink base. The bowl (or interior) dimensions are the ones that need to fit within the walls of the sink base.

For example:

Ticor SS6505:
...Overall Dimensions: 31-1/8" x 18" x 8"
...Bowl Dimensions: 29-1/8" x 16" x 8"
...Minimum Sink Base Required: 32"

Ticor S112 (this one includes a SS sink grid at no extra charge):
...Overall Dimensions: 31-1/2" x 18-1/2" x 10"
...Bowl Dimensions: 29-1/2" x 16-1/4" x 10"
...Minimum Sink Base Required: 32"

You have a cabinet inside width of 31-1/4" so a bowl that's 29-1/8" or 29-1/2" (like the ones above) will have plenty of room in a 33" sink base.

I have the same size base as you. I have Houzer M018 - It measures 29.5 X 19.5- They notched the side to fit it. I wanted the M022 - which is an Franke Orca knockoff, but it did not work with my soapstone (deep backsplash and soapstone transport issues). It would work for you, though because you are doing a solid surface. It is a beautiful sink and half the cost of the Franke. It is 18 gauge. I will post a photo when it is installed. Speak to your builder, notching the sink to fit into a smaller base is routine. Good luck!

I'm thinking, from reading your post, that you might enjoy a Rohl farm sink. One of those would fit in your base, they undermount easily and everyone loves them. It's a white sink and you'd have to cut away the front of the base. But they are durable and there are few complaints.

Goutgrec...I think farmhouse sinks need sink bases specifically made for them. Modifying a "standard" sink base is more than just cutting the front out. Doors have to be modified, structural changes have to be made to support the sink, etc. Did you modify a "standard" sink base for yours? If s/he has a very talented carpenter s/he may be able to make the modifications for her/him...but it might be costly. It can't hurt to check!

However, if Jessie21 hasn't ordered her/his sink base yet it's a definite thing to consider since I think s/he could have a bigger sink in the same size cabinet (but not sure as I don't have one.)

I dealt with the same problem a couple of months ago. My KD insisted that 33 inches was a standard size sink, but most sinks I liked needed a 36 inch base. I ended up with a Rohl Allia fireclay sink which fits great and is enormous. The granite installers had to make a couple simple modifications to the sink cabinet to make it fit, but it is exactly what I was looking for.

Thank you all for replies....i am looking at and considering each suggestion. Is notching cabs really such a standard thing? I took forever picking my counters too and ended up with lowes....paid for but not even templated yet cause i need the sink first. they have only one fabricator/installer that they use for solid surface.

A few individual answers:

buehl, it's "she", lol. From your suggestions, I would probably prefer the Ticor SS6505, because it's a bit shallower and that's what I like. But since it's description is so much like the one for SS6504, I just can't go there.

Here's why: my initial sink search was with GTS, when my initial intention was to duplicate what I have now, only switching to undermount. I ordered and received the SS6504, which judging from the description, model numbers, and price, is in the same family as the 6505. The inside of the sink was stamped CTECH-1, rather than ticor and there was a big patch insignia on the outside that read "Zambina", which would have been ok if the sink were good. (When I asked about it, GTS said ctech was a division of ticor). But there was a "dent" between the two bowls on the rim that looked like the stainless had been folded there...it was probably just where one bowl was connected to the other but I didn't like it and sent it back. It wasn't very heavy and I don't think there is any way it could have been 16 gauge and reading the description, it actually only says the rim is 16, with no mention of the body. Anyway, because of this, i am wary of GTS, despite the raves here.

mooring girl, the oceana would be the only one I could afford! But it does seem like a nice sink.

goutgrec, thank you but I don't think the farmhouse would work with my kitchen or my already there sink base!

What I really wish I could have is a single bowl, about 25-26 inches and about 7-9 inches deep. (not too big, not too small). I don't know that it exists, but if anyone knows of one, please let me know!! Barring that, I would probably go with a 28, possibly one mentioned here. thanks again!!!

From all I've read, it looks like if you get a free sink grid you're getting a Ticor; if not, you're getting a C-Tech. Also, remember that a grid will raise the bottom of the sink by an inch or so, so it's like getting a sink an inch shallower than stated. Think about the SS112--it has the free grid and I'm pretty sure it's a Ticor, not C-Tech.

I have a 33 inch cabinet and the sink interior is 29 inches wide.
Sink was bought from mexicopper on ebay. I believe I paid $550 for it. Size wise it would work. And now that we've had a copper sink we wouldn't want anything else.

It sounds like the Franke Orca in fireclay would fit your requirements. Check it out.

Tyrak, what a COOL sink!

I saw one similar to that in a plumbing specialty shop and they were charging $7000 (yes, that's seven THOUSAND)! And they said the price changes daily depending on the copper market. You got a good deal and it looks great.

I feel your pain! We are also looking for a 25"-26" undermount sink. It seems crazy that they aren't out there. We are putting in 32" base cabs (where the sink goes) -- so this size would be perfect. I don't have a lot of counter space so I don't want to go too big anyway. Let us know if you find anything. I am searching too so if I find one I will make sure to let you know!

simoneb, i'm still looking. Please, let me know if you find one and I'll do the same.

If you're up for fireclay, I decided on a Whitehaus 501, which might fit your measurement desires. I was also not interested in the really deep 10" sinks, especially since I was undermounting and not sure about a grid. It's installed now, and is gorgeous. Shop around, I got mine for $650 from BlueBath.

Whitehaus Fireclay 501 Farmhouse sink
outside:
26" wide
20 1/4" deep
8 3/4" high

inside:
24" wide
18 1/4" deep
8" high

Circuspeanut -- I just saw your sink! It's awesome. Perfect size, perfect shape... I just wish it was a little cheaper. Our budget is quickly vanishing. BUT... I still like looking at your pretty sink :-)

tyrak- Can you say more about why you like your copper sink so much? I like the look very much but am a little concerned about wear and upkeep. I read somewhere that you shouldn't pour hot liquids or place hot pans in copper sinks because of its low melting point. This will be my main sink so lots of hot pasta water will be going down its drain! Do you have any experience with it? Also, I've read warnings about buying copper from Mexico...not always well welded on corners and inconsistent thickness of bowls. Any advice? Thanks!

We pretty much love everthing about the sink. Aside from the looks which we obviously liked and the fact that no one we know has one, it has been pretty much maintenace free. There are certain foods which strip the color off and leave shiny bright copper spots. But within a day the sink starts to patina(darken) and it looks seamless again. And we've poured plenty of hot and boiling water down the drain and it's never been an issue. Copper is also naturally anti-bacterial so that's another added bonus. We also heard some of the warnings about the copper from Mexico. I will say ours is stoutly made and it weighed a ton. I went with one of the ebay sellers who had been around for awhile and looked through alot of feedback. That's about all I can think of to tell you. If you want I have pics of what it looked like before it was used and how it looks now after a year of use with no more upkeep other than soap and water.
