All you need is a set of drill bits, a screwdriver and a cordless drill. I masked the drill holes to avoid chipping when the drill went through the other side, used a small drill after marking and punching the holes with the metal bracket pieces for the back of the door. Each hole was drilled three times in ascending order. Once the holes were drilled it took 60 seconds to install, so easy. It is very durable and looks great.
