I was thinking the same as Trebruchet. A friend of mine had to do this for her new cooktop which didn't fit in the cutout of her previous cooktop. Her granite fabricator came over and enlarged the opening and it wasn't a big deal, though I don't know how much he charged her to do it. That sink is so wow. Don't get rid of it; see if there is a way to fit it.

I am replacing two bathroom vanity tops. Both vanities go wall to wall. One needs a 61.75 inch wide top. The other needs a 47.5 inch wide top. Both are single bowl. Don't want to replace the whole vanity, just the tops. At Lowes, I can get a standard off the shelf 61 inch white cultured marble vanity top for $209.00 plus $35 for two side splashes. I can get a standard 49 inch top for $149.00 plus $35 for the side splashes. If I order the custom sizes, price quoted is approx. $525 (61.75") and $415 (47.5"). Installation cost separate for both options. If I was going to pay those custom prices, I can get granite for less than $100 more total including installation (not white, though, which is my preference; I already have the granite quote for giallo ornamental, same as will go in the kitchen). So, I'm trying to decide if I can fit those standard sizes in the space I have. I will have to pay someone to do the work (I'm 51 YO woman, not able to fit under vanity to remove the old or install the new). Here is what I am thinking. Will this work? 1) 61.75" vanity top: center the vanity top and put filler wood strips on either side. They would be 1/2 inch or less, so side splash should cover them, right? I will be paining the cabinet, so no worry about trying to match a stain. 2) 47.5" vanity top: could we cut out the drywall somehow to fit the 49 inch top? What about trimming it off at each edge? Website says if you cut the edges of the top it voids the warranty. I read somewhere you could use a concrete blade on a circular saw to trim the edges. Suggestions??? EDIT: this is not my exact condo (it's in the same complex), but you can see how the vanities go wall to wall in the pics: http://www.realtor.com/realestateandhomes-detail/4206-Pinehurst-Cir_Little-River_SC_29566_M52157-40768#photo9

If I may, without offense meant, (I have a less than perfect designed kitchen too) say that when you get a new stove in here, the rest of the kitchen will look worse. :( The stove and kitchen ground each other. Having a new appliance will show off how the rest of the kitchen is over due for an upgrade. Again, no offense intended. If I was in this situation, I would figure out a way to get a new stove in that space and it may involve cutting off and closing off the cabinet at that corner there. If you don't have to accommodate that L shaped corner with the cabinets, it might make it easier to get something in there. Your brother doesn't have much counter space to the left of the stove anyways. A freestanding range can be a replacement if you don't have to make allowances for the L shape in the counter. You also are now freed up to buy a more standard size range instead of trying to get an odd size range in the space. I have a freestanding range in my oddball kitchen. I have nothing to the left of the range and I have a portable cabinet to the right of it. Best I can do in the space. Take the counter out and replace with something appropriate for the space (it's small, probably wouldn't cost too much), have the cabinets painted or sanded and re-stained and replace all the hardware with something pretty. The cabinets themselves look like there are in ok condition from the photo. New sink too. An undercounter sink for the new counter. If one is handy, some of this work can be DIY to save costs. I hope I didn't offend. It has potential to do better.

“What to do if the range doesn't fit the counterop opening?” ”we're planning for the Bluestar” Get a different 30“ range with the dimensions to fit. Or, you want only the Bluestar? Then grind down the counter. Those are your choices, that’s it. Your other idea about a cooktop plus wall oven…Your kitchen is 2-1/2 years old. You realize that a cooktop will need a counter to be fabricated for it to be installed into? A cooktop does not float in the air. The wall oven also needs a cabinet. If you meant a rangetop, it will have to fit in the space between the counters just like your 30” range would.
