Even if you're a DIY master, you may want to leave wall-mount faucets in the hands of a plumber, because installation is a little trickier than with a regular faucet. Sink-mounted faucets connect to exposed plumbing lines that run up behind the sink and stay tucked behind the vanity. But since wall-mounted faucets aren't attached to the sink, the plumbing lines are installed in the wall.
It's not a bad idea to ask your plumber to install an access panel in case you need to get in there again to fix a leak -- that way you won't have to rip your wall apart. Another consideration when installing a wall-mount faucet is the basin that the water will flow into. Ideally, the faucet should run right into the drain in the middle of the sink. If you choose a sink that's too shallow or the faucet is mounted too low, you're going to have to deal with a lot of water on your floor and countertops.
