Marble Systems, Dorr Avenue in Merrifield, VA (off route 50W)

I went all over NoVA, especially to many of the big importers farther west, but to me at least, the selection held at Marble Systems was better. High turnover.

Also recommend Dominion Granite and Marble for outstanding (laser) fabrication. Rated #1 in NoVA. They actually negotiate with Marble Systems for the slab purchase. Odd, I know but all do it this way. I had my marble acid washed by Dominion and it's holding up very well as a surface for 3 years with use.

We are heading out to VA tomorrow for some errands and in connection with our kitchen remodel, want to start thinking about countertops. What's the best/largest showroom to get an idea of availability and of price points? We are not looking for purchasing yet and don't want to waste the time of a salesperson since our contractor might direct us to another vendor. But i'd love a place where i can just walk up and down aisles and look at every type of stone available where it also tells you price point, so we can start thinking ahead. (This existed in our old state! Maybe not in DC?)
