I'm planning on putting in a 30" single basin soapstone sink. I''ll have Kohler Vinnata Faucet and a cartridge-style water filter (like Body Glove). I'm also planning on getting an insinkerator evolution garbage disposal with an air switch. My dishwasher will be a Miele Optima. The sink will be made for me with the drain hole offset to the right corner. My contractor would like me to purchase everything through him since he'll get a mark-up. He says that I might order the wrong accessories to go with the various components and he would make sure that we have all of the right stuff. That would make it easier on me. But I'm finding some pretty sweet prices online and I would really like to save some money. So I would like some more information. What things do I need to get to go with the faucet, the garbage disposal, the water filter and the sink drain? Should I let my contractor order or should I do it myself? I'm cross posting this with Kitchens just in case I'll get more responses there.

How thick is the sink? You may need an extended flange. You should buy everything yourself if you can get it cheaper. The only reason he wants you to order through him is so he makes money off of you. If he is honest, he will tell you if you need to order any accessories and what they are. If you need an extended flange, Insinkerator makes one to fit their disposers. They also make an air switch. I don't know anything about the filter, however.

I was the one that had the major issues with all the pieces working together. I haven't been on GW in awhile, and missed this thread. I started the "Lose my Mind" thread about it. Long story short: YES you can use the ISE OR the Rohl extended flange with the Shaw sink. They are EXACTLY the same in design (I bought both- don't ask). I used the Rohl because the finish was real chrome (to match my faucet) which the ISE is a "polished" stainless steel. The color isn't really the same, and the ISE has the logo on the rim. I originally purchased a Waste King. This DID not fit with the sink/extended flange, even though thier website says it does. DON't get it. It will not fit. I bought the ISE Evolution (1 HP- the top of the line for ISE). I have been very happy with it. BTW- anyone want the above mentioned ISE extended flange- super cheap? I tried to sell it on Ebay, but is such a specialized part. Hope that helps!!

I have an Artisan stainless undermount sink with soapstone. The guys who installed the soapstone added wood supports to the sides of my sink cabinet. The sink rests on the supports. The soapstone was placed over the sink and then silicone caulk was used to seal it. I don't remember if they also used an adhesive. I did not want my seam in the middle of the sink, so it was placed to the left of the sink (you can see where the seam will be in the first picture.) This shows the wood support on the left side of the sink cabinet Here's the installed sink. And finally, the soapstone
