So glad you posted this. I will have to see if it is available here in Austin yet as I've been wanting something that looks like white marble (but is tougher) for my bathrooms. I'll post a picture if they have anything larger than one of those tiny little tiles that I can look at. Even if all they have is a tiny tile, I'll try to let you know whether I think it looks similar enough to white marble to "pass" or just looks sort of cheesy. I'm using Silestone in the Amarillo Palmira color in my kitchen and will probably stick with that there b/c I don't think DH would like white countertops in the kitchen. Again, thanks for the heads-up!

I live in California. Most granite/marble/quartz here is 2cm although 3cm can be found. Cabinets have to be level no matter what. I have Caesarstone on my perimeter counters that are 3cm with no laminated edge. My island is 2cm marble with a mitered edge that doubled it to 4cm. My butcherblock counter is about 1 1/2" thick (a little less than 4cm). So all counters are a different thickness and I don't even notice the difference in thicknesses. I think the thinner edge is slightly more contemporary looking, but it's really up to what you like. Plywood with metal supports on the island before the marble was installed: 3cm Caesarstone (Arctic White), 2cm marble, 1.5" butcherblock:

I just wanted to follow up on the countertop I chose. I loved the look of shiny white marble but knew that our family would ruin it. I ordered a sample of okite, as I mentioned above, and the veining was very green. I happened to see another sample at Ikea that had no green veining. I asked whether I could see a full slab and they told me the name of the company that supplied Ikea's product. I went to their plant and asked to see the slabs. For some reason, they did not want to show quartzite slabs, but only wanted to show granite slabs. It must have something to do with the commission. When I insisted, they let me see the slabs. Some had green veining, some had a lot of black veining but some had a very white background and a small amount of black veining, just like marble. I chose the slab and they were installed about 9 months ago. I LOVE THEM. They are stain-proof, etch-proof and beautiful. The veining does not look as authentic as marble, but it is close enough for me. I will post a picture later (my kids took my camera) Thought you might want to know to look for Zodiaq/Okite Bianco Carrera

I personally don't think that Ceasarstone and Silestone look anything like marble but I guess there are a lot of kinds of marble so I wouldn't know. I think that the two products are virtually the same and the choice comes down to color, availability and price. Depending on where you live, you may have better selection with one or the other, a good fabricator, or not.
