There are way too many variables for anyone to give you an worthwhile estimate here. You need to sketch out what you want and contact three or more local contractors to give you their estimates based on local building codes and other constraints (of which there may be many).

Ladeda -- Our fabricator was Alpha Granite. We were on the verge of having them install Caesarstone but when I went to pick up C'stone samples from their office I saw some pieces of soapstone from Dorado sitting out on the counter. My husband and I had been to Dorado earlier and loved the soapstone we saw but couldn't find a fabricator from the list Dorado gave us (I called a bunch of them and they all tried to talk me into granite!). In any case, Alpha gave us a great deal on the fabrication because they had just decided to start using Dorado as a supplier and needed to get some soapstone installs under their belt. Sorry -- probably more information than you need. The bottom line is that they did a good job. We only have one seam and it's fine. I've always wondered what it would look like if a more experienced soapstone installer had done it but it's not bad. Just a bit more noticable than I had hoped for. I can take a picture of it if you'd like to see it. And, as far as finish, I don't think they did anything to the stone once they got it from Dorado. At least it didn't seem any different to me. Our install was done nearly 2 years ago so they probably have more experience with soapstone now and maybe can give you names of other customers you could check with. Or maybe Dorado has a better list of fabricators now. In any case, we love our stone. It's probably my favorite part of the new kitchen (or maybe the dishwasher . . . ). Good luck.

Are your cabinets going all the way to the ceiling? 10' is very tall. Did you account for crown molding if any? We have a 10' ceiling in our kitchen and took our cabinets only up to 9'. Even at 9' the top cabinets are inaccessible except via step stool/ladder. The top shelves in our lower cabinets are similarly inaccessible. If your broom closet is made by the cabinet maker and is considered part of that bank of cabinets I would consider putting false panel details on the side that faces into your kitchen for aesthetic reasons. I would also try and make sure the three doors above your appliance garage are equal width. It does not show this way in your drawing but I'm assuming it's not accurate. Personally, I would not care for your kitchen island. IMO there should space on either side of a range surface. A minor aesthetic nit pick is that the circular counter top section does not blend smoothly into the sink-side edge of the island, I think this is because the radius of the circle is a little too large.

Mama, I have the old style mechanical SQ TL and it is fine. But, I wanted to tell you about my experience with my Bosch Nexxt FL. It sounds as if you are having a similar issue. It worked intermittently. Sometimes it was fine. Sometimes it wouldn't spin dry just drain. I just never knew when it would work or not work. This behavior became more and more frequent until one day it wouldn't spin at all and ceased to work. I did some research on my particular unit at GW. Because it was out of warranty I called for service. Armed with my GW information, I insisted that the service tech do a computer diagnostic. Just to be thorough he checked one or two other possible mechanical issues. The barrel spun freely with no problems. After he did the diagnostic, we determined the control board needed to be replaced. He also said the barrel bearings were in the process of wearing out, I had too much play in the barrel and it would go bad in the near future. Between both costs, I decided to replace the washer with the SQ TL manual. The reason I tell you this is your repairman can replace every item in the machine and that control board still won't work. Until he does a diagnostic on the electronic control board, you won't have an answer. Insist that he do it. Aside from the miserable customer service at the appliance store, you've got a repairman issue. This shouldn't have been that hard to fix. Have someone with the right equipment check the control board. I still contend that you need a replacement unit. Go for the TL manual basic. It's a good product.
