The Kohler Whitehaven comes in a short apron and tall apron size - one of them would probably fit. The apron on the Whitehaven is self facing so your contractor does not need to make the perfect cut required of most farm sinks. It is also made of durable cast iron. I have one and love it. The Kohler Vault is stainless steel and also comes in a short apron and long apron style. Both come single bowl or uneven divide.

I have the 36" Whitehaven in my 36" sink base cabinet. The sink is a bit under 36". It does come smaller.

The Ikea Domsjo apron front sink does not have as tall an apron as most farm sinks - why you should check out the shorter apron styles in case your cabinet doors are too high for a standard farm sink. That is one thing you need to check on.

We have a 33" Cerana in a 36" Sektion cabinet. That's Blanco's recommended cabinet size for that sink.

We debated on the Whitehaven, just for the ease of installation. (We are DIYing it.) We checked it out in person, and just didn't like the cast iron.

We are still mid-renovation, but I'd be happy to answer any questions you may have.

We also have a Kohler Whitehaven. I believe ours is 33", and it's the one with the shorter apron so that we could keep our existing cabinets. Our contractor just reinforced underneath with a couple of extra 2x4s. The sink is AMAZING. It's SO sturdy and Kohler has a really good warranty on it. It's absolutely gorgeous and SO functional. We plan to build a new house eventually and will get the exact same sink (except maybe bigger, since we'd be able to!).
