I posted here about the possibility of a marble sink in my kitchen. If we decide to proceed with this idea, I'd like to mitigate the risk so that if it doesn't work out the sink can be replaced as easily as possible.

I was daydreaming about a 48 inch farmhouse sink with one 30 inch bowl and one 15 inch bowl (I'm assuming I need to allow a few inches for the walls of the sink.). Thus gaining the ergonomic advantage of the farmhouse style, the huge bowl for washing dishes and a second decent size bowl for kid handwashing, soaking baseball pants, etc. The problem with this daydream is that it would lock us into a farmhouse sink because of the cabinet type. And the size is too big to be able to replace without another custom job.

So I think I have two options here to avoid that. One is to ditch the apron front.

I could still have a huge double bowl sink and if we needed to replace it we would have to replace the countertops as well in the sink run, but at least the cabinetry could be reused--I think?

The other option is to go with the apron front but to shrink the sink to 36 inches. This appears to be a somewhat common apron front sink size so we would likely be able to replace just the sink if necessary. If I went to the 36 inches, is it possible to divide that into a double bowl configuration and still have usable sized bowls? I guess I could go 25 and 9. Those sound smallish to me, but maybe they would work. I did have a 24 inch ikea farmhouse sink in the last kitchen we had and it worked great for me so maybe 25 would actually be just fine? Even if it is, is 9 inches worth even having? It would be awfully nice to have a separate bowl for a colander of fruit to drain while I'm scrubbing a pot or for the kids to wash hands while I'm filling water glasses for dinner and so on. I am thinking we would install two pull out faucets.

Thank you so much for any help on this!
