There are quite a few options. There are some white granites, one called super white, although it may not be as available anymore. The best thing to do is to visit your local stone and granite suppliers where you can see whole slabs, depending on where you live. They would be more knowledgeable than me.

Quartz would be a good option too. Torquay by Cambria, London Sky by Zodiaq is pretty convincing along with a lot of new introductions from several companies this year. I always recommend seeing a whole slab when it comes to Quartz countertops - you can't tell much from a small sample - it just gives a glimpse but is useful for coordinating color.

Liz, Can you please tell me more about the refrigerator with cabinet front in this photo? Is it difficult to design? What kind of frig? I think this looks fantastic.

Thank you Lori! This is a Sub-Zero refrigerator, part of their Integrated series. There are other brands that have "Panel-Ready" refrigerators too. Each manufacturer has their own specifications for how the panels are built so it requires a custom cabinet line or a custom cabinetry shop to fabricate them. Sub-Zero has excellent guidelines and they are true cabinet depth refrigerators, meaning the door and box of the refrigerator are about 26" deep.
