We have finished our Masterbath countertop. It's been a long time coming. In an attempt to fix a leaking faucet almost a year ago, I cracked the marble countertop. We have been washing our face, shaving and brushing our teeth with the kids in their bathroom. I decided to attempt to make my own Concrete countertop and it worked. New under mount sinks, faucets, knobs on the cabinets, lights, tile and next venetian plaster on the walls. Now we're back in business.
