you could do a wood-look porcelain tile http://www.porcelanosa-usa.com/products/tile/parker-porcelain-wood-look-tile/ascot-grey.html

I like your vanity very pretty. There are some beautiful faux marble porcelains now that would look lovely with your dove grey vanity. I used a light grey long thin LFT layed in a herrigbone pattern that I love too. I think you should take a door of your vanity with you to a tile show room there are so many great tiles out there. Good luck!

Do you like patterns? The cement tile has tons of options and there are some porcelain tiles at Home Depot. The vanity is lovely!

Be careful when looking at the merola tile I feel in love with one they showed in a bathroom but when looking at the specs most had a DCOF of less than .42 which is not safe when wet... The one linked above has a DOCF of less than .42 so like ice after a shower... But pretty!

Check out this tile, we used it in our master bathroom and it looks great with the grays. It would look very good with your vanity top too. The pictures online don't do it justice it's much nicer in person and it's perfect for the floor not slippery at all. I got mine at lowes, it comes in lots of shapes and sizes.

Not a good picture at all, taken during installation. But gives you an idea of the color. I have it vertically in the shower in a different size. It is grays with whites no brown, on my monitor it looks brownish. It's not.
