That depends on the type of spigot and the access you have to the plumbing. Most are easy if you can get to the bottom of the sink with your tools. (Plumbers have tools that most people don't have handy to reach those hard to get at places). I've replaced several in bathrooms and kitchens with no problems. I've seen a few that I wouldn't even consider trying. Look it over and make sure you have the proper tools as well as enough space to properly use your tools in that space. You should be able to find D.I.Y videos on Youtube for almost any brand or style.

Nope. These videos will walk you through it in no time.

Hubby and I have replaced many faucets. Just make sure you get the faucets that go with the holes in the sink. If you have more than one hole, you should be able to get the plate that covers the other holes if you get one that uses only one hole. If you only have one hole, you need one for only one hole. Remember to turn the water off to that sink and have something handy to catch any water that still may be in the pipe when you loosen the faucet.

No one mentioned that you need to be able to get into the cabinet, lay on your back, and work with the tools. If you can do that (use a blanket or a pillow under you to prevent bruises), you are on your way!

I replaced one in my bathroom pedistal sink and I have a new respect for why plumbers charge what they do. Never again!
