In general you don't want to cut granite in place if you can avoid it. It's really messy and the person doing the cutting will almost certainly say that they take no responsibility for cracks or damage because you never know. If you already know you want a larger cooktop but can't afford it right away, for instance, then I would talk to your contractor for options. Perhaps some sort of fill material that can then be easily removed. Maybe even have your granite person make a filler piece from the granite he's cutting out anyways and then put in place temporarily. The gap or seam can be filled with clear chalk and when you are ready for the new cooktop, just remove the filler. This is all provided you already know what you want eventually. If not, then that's probably something you should figure out sooner rather than later. BTW, most cooktops have a reasonably standard cutout dimensions for either 30" or 36" so you might not need to decide on the specific cooktop now. You probably *do* want to pick out a couple of likely suspects and make sure you have a cutout that can accomodate all of them. There's usually at least 1-2 inches of "lip" around the perimeter so as long as the edge of the cutout sits within that perimeter the you're fine. Look for the minimum and maximum cutout dimensions for each of your choices and make a cut out that's about 1/8-1/4" larger than the largest in each dimension and then check that to make sure each dimension is less than the smallest "Max Cutout" in each dimension. Clear as mud? :) Good luck.

Ours had the option of 4 screws through the sides or 2 in the sides and 2 into the underside of the counter. We went with 4 through the sides rather than having the fabricator risk the counter. It also makes it easier to swap out dishwashers when it goes.

The holes for my bathroom, laundry room, and kitchen faucets were drilled at the fabricators shop. When they came to the house to measure and template we discussed exactly where we wanted the holes to be placed for the faucets, soap dispenser, and the air switch in the kitchen. I did not have those items in my possession at the time. I did tell them what faucets I was using. I had my sink but they did not take it or the paper template with them. They said they would get all the needed specs. on line from the manufacturer. The fabricator I used was completely high tech and used computerized measuring and cutting systems for the process. All cutting was done at the shop and everything fit perfectly. The sinks where installed in my home by the fabricators and then hooked up by the plumber.

I need to make a provision for a RO faucet next to the main faucet. Any suggestions or help is greatly appreciated
