Try the furniture guild or porcelanosa. I think Furniture guild is a stone based while porcelanosa is corian like but they both have tops with offset sinks. See page 13 in the attached link for the Kole sink. I would recommend Duravit but their options leave you with their vanities as an option. They are ceramic and I think the only offset sink is the Scola. Another option is just to have a countertop fabricator make you an offset cutout for a sink of your choice. Good luck.

What's holding you back from buying local? I would be afraid of the counter cracking during shipping if bought online. Local stone yards sometimes have remnant pieces that are discounted. But with you needing two sink cutouts, there's some work to be done on the fabricating side (work = $$). I have a 72" vanity alcove. Everything online I found for the countertop was 73" (because the top usually hangs slightly over the sides of the vanity) but in my case, my vanity is between two walls so I had to go local to find exactly a 72" top. Granite was about $800, Quartz was $1050. Both of those prices were for remnants. Cambria quoted me $1600! NO WAY was I paying that. Good luck! HomeDepot has tops but I don't know if they offer what you're looking for. I'd suggest looking local.

Thanks! Agree about the floor and windows being too much. Consensus seems to be do the windows and not the floor. Budget and practicality may make me choose one over the other (ie I must change the floor but need not change the window). You can just see the windows in this picture (the two windows through the arched doorway). (This was the LR/DR will become master bedroom and ensuite): Everyone seems to prefer the look of the second vanity, so I will focus on doing something similar. My head was turned by the beauty of the first, but I will let it go and move on now. nosoccermom, I will have the trough, rain shower overhead and separate handheld. Haven't turned my mind to tile or solid surface in the shower, I'd love solid surface but I'm thinking I should do tile? I love the vanity you posted, it would be great in my current house but for this place it is too sleek. I still want modern, but with more texture/age I guess. I have to mix the feel of the new-Georguan house with my minimalist/modern aesthetic. Black or bronzed fixtures? Any pros and cons? I think brass and gold would be too shiny, but I've seen some nice weathered brass.

Go to the better tile showrooms in your area; they will have plenty of options and sizes for your project. Once you start liking a tile line, it's easy enough to pull the rest of the elements together; but you need to see what's appealing to you in person.
