I like the look, feel and durability of concrete counter tops. This video goes into considerable detail on how to make your own mold from readily available material, how to mix and pour the concrete and how to install the finished product on a standard bathroom vanity base. There are companies, like the one mentioned above, that will custom make a concrete countertop for you. However it you have the do-it-youself spirit and love the idea of trying this, then you'll find this video particularly helpful.
