A new bathroom faucet. (Moen / March 17, 2014)

It's not the largest feature in a bathroom but a faucet can go a long way to update a vanity or sink. If you have an old single-handle faucet, you can replace it with a new one designed specifically for do-it-yourselfers. There is a nice array of finishes in single-handle faucets, so you'll be able to find one that matches your bathroom accessories.

Faucets designed with the DIYer in mind are easy to install because you do most of the work above the countertop -- so you don't have to lay on your back with your head in a dark cabinet trying to see what you're doing. Faucet manufacturers have figured out a way to pre-assemble the unit, eliminating the daunting task of making all the parts fit together. You have to empty the cabinet (it probably needs a good cleaning, anyway) so you can reach inside to hold the faucet while you tighten it. For tools, the bare minimum is required, just an adjustable wrench and a screwdriver.

A plumber will charge $304 to remove an old single-control faucet and replace it with a top quality new one, but you can buy a new one for $170 and install it yourself, saving 47 percent. The replacement gets more complicated and expensive if the existing faucet is very old or has two handles, which usually requires a different type of faucet.

Tip: Don't forget to turn off the water supply lines under the sink before you begin this or any faucet project.
