+1 for Porcelanosa
Worth checking out Mosaic Tile. (Dianne there is great). Tile is well priced, though perhaps less interesting than Procelanosa. Mosaic does have vanities to purchase, though some of the quality is mixed.
For vanities, you can also look at Fergusons to see if anything is to your liking.
Custom is great--what we did in master. But far more expensive, as you are paying for cabinets, pulls, tops separate, rather than as all-in-one units.
