I have a Kohler Whitehaven apron front sink and like it very much. I have a single bowl, and like you had always had a two bowl before. It worried me to make the switch because I do hand wash some dishes every day and was used to using half the sink as a dish drainer. However, I have come to really like my single bowl. My sink does come in a 70/30 low divide and I would have gotten that if the smaller side had been on the left instead of the right. It just has to do with my own preference - dishwasher is on the right so I wanted the larger size sink there too. The sink is very large compared to my old divided sink even though it is the same size - in the sam sink base cabinet.

I have had my sink two years and with minimal care my edge is very clean. I have a negative reveal (countertop slightly over the sink) which is the least recommended, but it has worked fine for me. I really like how close I am to the sink. It is deep. I have the grills for the bottom and they really help keep the sink clean and decrease metal scratches, which are easily cleaned out, but it is nice not to have them to start with.

The only drawback to apron front, at least with mine, is there is not a cutting board that can be inserted on top of the sink. I would not use this set up anyway, but many love it.

I ran across this pic recently - an interesting combo look. It is an under mount sink with a piece of stone (?) across the front. It is not as close as a true apron front to the person at the sink. The cutting board insert is an example of what I was referring to above:

I agree with iamtiramisu on the single bowl sink. I just switched to a single bowl with our very recent kitchen remodel and I LOVE the single bowl. SO easy to wash my large items that don't fit in the dishwasher.

The point that I differ on is the reveal. We went with the overhang and I will say that it find it very easy to keep clean and have not broken or chipped anything on the edge. I had the positive reveal on my old sink and hated it collecting crumbs that I would brush into the sink from the counter. It has a very clean and neat look that I really like.

I did have to go with the size you are looking at (because my sink is in the corner and it is the only one that would fit) and I was very worried about it being too small. (We did get one that was deeper to make up for the lack of size the other way.) Not a problem, I have found the size very workable and easy to use.

Currently the most popular sink I install in my projects is a large single bowl. It's split 50/50 between a farmhouse single bowl and a stainless under mount single bowl. That being said, it is a preference and you should go to a showroom and see them in person before making a decision. I personally have a 70/30 sink which I really like. The smaller unit has my garbage disposal and I use it for defrosting items as well. The larger side is wide enough for a standard size cookie sheet to lay flat.

Regarding the comment about the ledge underneath the countertop, yes there is a maintenance issue. It can get moldy and you must keep up with it.

What width sink can you do? What is the width of your sink base cabinet?

I have a 30” wide single bowl and love the elbow room and not ever having to bang into a divider.

We always go to my sister’s for Thanksgiving, and she just changed out her kitchen counters and also switched from double bowl sink to single bowl. I always help clean up. What a relief this year to clean all the Thanksgiving pans, bowls, racks, etc. in her new single bowl sink.

Also if you have a disposal in a double bowl sink, there’s always one side with a gross strainer that you have to dump into the other side with the disposal. Who wants to do that.

One more advantage is that with one bowl, there is a little more space under the sink for storage with plumbing for only one bowl. Especially if you choose a single bowl sink with an offset drain like the Whitehaven apron front or the BlancoDiamond Super Single. Once you have an offset drain, you never go back to a center drain.

Here is a photo of the Whitehaven so you can see what I mean about the drain. I do not have this sink, I have a SS undermount single bowl with offset drain. There are pros and cons to each. (P.S. I don’t like the bridge faucet pictured. I like a single-handle faucet, but that’s a topic for another thread.)

I went from a stainless double bowl to a 70/30 low-divide Kohler apron-front Whitehaven sink (cast iron)...LOVE IT!

I like the big, single bowl when I need the space, low divide allows for pan handle overhang, plus the small bowl is great for a small amount of soapy water or draining the small numbe of hand washed dishes I do. I was skeptical when I ordered them, but get grids!!!

Hey Nat, if possible you should look into centering the new sink under your windows. Put the dishwasher on the right and another cabinet on the left.

The big kohler low 70/30 is the perfect compromise. Put the disposal in the 30.

Ha! My DW is on the right so that seems natural to me as a right handed person.

If you do add the fridge on the same wall either get a counter depth or do a cabinet around the deeper standard so you it looks more built-in. See how the top comes out to the front with cabinets above. Extra storage and the fridge isn't jutting out past the counters with the ugly sides showing.

There are pros & cons for each type of reveal (that's what it's called regarding counter overhanging the sink or not):

.

Positive Reveal -- where the sink shows/granite is cut slightly larger than sink

Pros:

• Easier to clean b/c you can see the gunk and can easily wipe it off (it only gets nasty if you leave it there)
• You can use the ledge to put a cutting board over the sink (assuming a cutting board is available for the sink or you can find one to fit)

Cons:

• Silicone (caulk?) might be visible, but if they use clear you won't see it when it dries

.

Negative Reveal -- where the granite overhangs the sink

Pros:

• You cannot see the gunk buildup
• Easiest reveal for a fabricator b/c s/he does not need to be precise with the cutout since the stone will hide any mistakes following the contours of the sink consistently.

Cons:

• You cannot see the gunk to clean it.
• Edge underneath is not polished so gunk is more likely to "stick"
• Dirty water/food can splash up & under where you cannot see to clean it.
• It's difficult to see underneath to check for gunk w/o leaning way over & into the sink.
• Dishes have been known to break b/c when you lift them out near the edge of the sink the dish hits the stone counter & can break (or, if the dish wins, the counter could chip...but I'm not sure how likely that is).

.

Flush Reveal -- where the granite & sink are the same

Pros:

• Easier to clean b/c you can see the gunk along the edges
• No platform over or under for the gunk to collect

Cons:

• Very difficult to do perfectly
• Silicone might be visible, but if they use clear you won't see it when it dries

You will find proponents of all three types of reveals here...but in the end it's what works best for you.

I would favor a large single sink with integrated cutting board, drain

it is very flexible

Do you have a garage? Maybe move the old fridge to the garage. Very handy to have that extra space for drinks and storage of little used condiments.

About the ledge on an undermount....one thing I really like about the one deep sink is that you can have the counters cut to the exact size of the sink so there is no lip.

Look carefully at the edges. The only lip is on the front of the sink.
