Leaky Bath Faucet - Attempt to Repair or Call a Plumber?

Pretty easy to do but does require a few specialty tools to pull the valve stems out and either change out the parts or simply buy new stems and replace the old ones. It takes a pretty deep socket type tool to reach into the faucet body to access the stems and any big box store will have that set of stem remover tools.

Depending on what faucet you have, you may be able to find new stems at a big box store, but it is best to take the stems to a real plumbing supply place so you can get exactly what you need.

First things first is to turn off the water coming into the house or once you remove the stems you're shooting water everywhere.

"I am not very self sufficient with home repairs"

Just call a plumber.

There are tons of different valve stems that you have to match up. And you need to know how to shut off the main water supply, etc.

It’s not that complicated if you have the right replacement part, but if you screw it up your water will be shut off until you get a plumber over to fix it.

If you can't get the bonnet nut off by twisting with average force, don't try to use your muscle to untighten it. Either call a plumber, or get a large set of slip joints to bend it or crack it free, then replace the trim kit.

Trust me. Otherwise you can break the copper supply lines and end up with a shower remodel on your hands. Or so someone told me...
