i feel safe with the 1/4" difference.
23 3/4"
23 1/2"

Thanks for the response Davidrol. I just got off the phone with American Woodmark and the interior dimensions of the cabinet are actually 281/2" So I could conceivably go larger. I just don't know if anyone actually makes a sink that size.

Do you happen to know if there is one?

it is normal for there to be 28.5" inside a 30" cabinet.

I may not understand fully - since you haven't described fully - what supports are in place or expected, for your "apron" sink. Someone else might know all this in advance. Perhaps for the crowd you could explain more, and hope someone else will answer.

Perhaps you want the largest apron sink possible for this cabinet. Call back and ask them. They will have seen this before.

ask them to name names of sink makers.

The question will have come up a thousand times before.

25" is a standard size for a sink, and it will fit into a standard 30" sink base. Fireclay sinks vary in individual size even though 25" is a standard sink, the actual size could be 25 1/4" or 24 7/8" etc.

Thanks for the replies davidrol - I did actually call them and got confirmation on the interior cabinet dimensions and you were right: 28.5. I will call and ask for manufacturers next time (forgot and hadn't seen your post yet - my email notifications aren't working for some reason).

Just to clarify, as I was writing in my shorthand thinking style, so it is confusing. We got a deep sink base cabinet - it already has an opening 23 3/4" wide, 2" deep to accomodate an apron front sink. It is not a standard cabinet, but one made specifically for apron front sinks. It is a 30" sink base and the interior dimensions (from plywood to plywood) are 28.5 inches.

I want the maximum sized sink for the cabinet. We do not like the sinks that accomodate a faucet - we want the faucet in the counter behind the sink. We do not like the "angled" sink - where the top diameter is larger than the bottom - we prefer the "squared" off look. The 26" Alfi has a lip around the top and we don't like that either. Just a straight simple sink.

Hope that helps a bit. Also, here are the manufacturers I've researched and the results:

Barclay, Whitehaus, Belle Foret, Bella Lavello, Porcher - either too small or too large
Franke - don't want the front of my sink branded
Herbeau - OMG, would love one but can't afford it
Kohler - a possibility, but for the price would rather have a Rohl
Rohl - our top choice in the 24" now, but wanted something larger
Ikea, Marvel - don't like the faucet in the sink
Elkay - only does stainless and copper?
Alfi - has the lip in the size we need

I hope this helps anyone else reading. If budget were no object, this obviously wouldn't be an issue, but I think $1k for sink is more than enough money to spend (the Joneses are of no consequence to me).

livewireoak - I haven't found any 25" apron front sinks in fireclay (did I forget that important part - fireclay? ugh - this project has my head spinning).

Thanks again!!

Hi there,
I am literally in the exact same boat! I have Martha cabinets coming and bought the 30" sink base for an apron front sink. Really don't want to go as small as most of the options seem to be. Based on dimensions alone, the Franke is the closest but I can't stand the logo on the front!
Also just found a 26" Whitehaus...may do that or the 25" Kohler.
Good luck!!

Here is a link that might be useful:

Hi Bungalow38! Do you have a model number on the Whitehaus? I was only able to find 26" with a decorative front, not plain white....so now, of course, you've got me scowering the web looking for it! ha! Good luck - I felt the same way about the Franke - you may want to call about that logo - I've seen it on some and not the others. I was at a design showroom yesterday, and while she wasn't overly familiar with the brand, she said it's possible that it's reversible.

Good luck to you too!

I have the all white Whitehaus 501 and love it, but alas, I believe it's been discontinued. Perhaps scour eBay and suppliers to see who still has one in stock?

Argh! Indeed, I can't seem to find it anywhere beyond the spec sheet. I may just go with the Franke....perhaps I will call and see if I can request one without the logo....? I saw the 30" Franke yesterday and it had a much more subtle logo inside the basin and was finished on 3 sides. And it was gorgeous!!

Problem solved! (For me anyway....might work for you too though.) I called Franke and they confirmed with their warehouse that the sinks are branded with their logo on the INSIDE of the bowl, on the right hand side of the sink. The photos that show the logo on the apron front are old and they have not been making them that way for a while. If you get it from homeclick.com, there is a 10% off Franke coupon through 7/18: FRANKE10 that makes it $810. That's the best deal I can find so I'm going to get it from them. Hope this works for you too!

I bought the 24" London Porcher stainless steel apron sink, and had a 24" base made for it. Here's a link from FaucetDirect (which is where I think I ordered from... so many boxes, can't remember what came from where anymore!).

Sorry - just read the fireclay comment - it does come in fireclay as well!

Hi BossaNova
Does the 24" Porcher fit in a 24" wide base??
I thought you needed to go bigger in the base than the sink? A 24" base would be perfect for me, but I really ONLY 24" for the base. Good news for me if it works!

Hi Lisa - our cabinets are custom, and the base is exactly 24". This isn't the most flattering picture, as we are mid-installation, but it gives you an idea. We have a garburator on the right side and a pull-out for cleaning products that will be installed on the left.

Good luck!

Thanks!
I'll run it by our contractor.
Hopefully it'll work.

What sink did you end up going with? I'm in the middle of a kitchen reno and have a 30" base cabinet and am looking for the largest farmhouse sink I can put in. I saw the Kohler and Rohl but the Kohler is shallow so not the ideal and the Rohl is too rounded. I'm also looking for something on the sleeker side so as flat as possible. Thx!

I'm having the same issue. Wish there was a 27" sink option to fit the 30" wide base cabinet. For the Rohl, the sink is 30" and the manufacturer recommends having a minimum of 1 1/2" on each side, so that would be a 33" inch base. But i've not been able to find a 33" wide base cabinet. I would love to see what a 24" sink looks like in a 30" base cabinet - does anyone have pics? Thx!
