There are restrictions for the use of frost-protected shallow foundations. What is the foundation of the existing building? Will the edge of the new addition abut an unheated space or foundation (like an unheated basement, crawl space, garage or porch)? Will the addition ever be unheated?

We used Eurostone Craft in Chantilly as fabricator for our new build. I worked with Meg. The entire experience was fantastic. I visited all of the suppliers joaniepoanie listed. Our white fantasy came from Marble Systems and our carrara came from NSI. Marbles Systems was great - make an appointment for better service. NSI was not nearly so pleasant, but I loved the stone, so what can I say? Eurostone's fabrication and installation was flawless. Eurostone has lots of slabs in stock, but not exactly what I was looking for.

I checked the websites you provided, and only Bramiti showed Jet Mist (same thing?). I sent them an email to inquire about it. I've asked about it at many granite "stores" in the area, and my KD and tile guy have been trying to find it also. Rock Tops in Owings Mills told me they would go directly to the mine to inquire about it, so we'll see. I need to find a slab large enough to do my island, or else I either have to revise my design (do not want a seam in the island) or go with corian that doesn't show seams. Since this affects my design, I need to know if I can get this in the slab size I need. I also need to know if this is a bad choice for me - I am not a great housekeeper and have 2 teenagers who are great kids but they're still teenagers.

I don't know so can't elaborate on why you are confused since it might confuse you futhur. Drain rough in is 2" pvc standing an extra 4 to 6 inches higher than required for final trim. Tile installer cuts pipe to match his planed installation then furnishes and installs finish trim and strainer. I don't see any trim or strainer so yea,it certainly was poorly installed. When origional tile is demoed,tile installer either works to height of drain as already in place or busts it out and starts over.
