Houzz is the new way to design your home.
Epoxy grout. It is more expensive, unwieldy to work with and stinks. But epoxy grout has a big benefit over its sanded and nonsanded cousins: It makes it difficult for mildew to grow, and liquids have a hard time penetrating it. We have been installing it frequently in master showers and at kitchen backsplashes (where food and grease can splatter) with great results.
For this in bath I selected the model "Campus" tiles of 3X6 beveled form the incredible Waterworks store in Miami. The floor is white thassos slab purchased in Eurostone in Houston Texas. The "Twiggy" lamp was a decision to create a hip style, from Foscarini. The washstand was selected from the same Waterworks store.
A wall-mounted vanity will give you some undersink storage while visually opening up your bathroom space, since you can see the floor all the way back. If storage isn't such a huge issue, but the feeling of being crowded is what's bothering you in your small bathroom, this solution is still better than a pedestal sink because of the storage space. And it isn't any harder than hanging wall cabinets in the kitchen.
