bathroom vanity unit

here is a image of a bathroom vanity unit my brother built , we both share similarities in trends and styles within design ,which in turn I incorporate this into the interior side as he does with architecture. here he has used walnut and a concrete work top,to achieve this colour he used normal builder sand if you are unaware what this is it looks like the ( sand you see at the beach), but to achieve a more grey tone you use sharpe builder sand which has more grit in it. we both believe that the concrete compliments the walnut and allows it to be come more rich in design. the concrete is a simple method and achieves a very durable look with certain materials and is also cheap and easy to produce and the final look is very impressive as you can see.
