A clawfoot tub faucet replacement is actually fairly simple since all the plumbing for a clawfoot tub is on the outside.
Here are a few simple steps to get you started.
Step 1 - Choose the New Faucet
There are several retailers and etailers that specialize in new plumbing that looks vintage, just like the typical clawfoot tub. These faucets incorporate all the new technologies but retain the vintage look and feel that you love.
Remember that any standard faucet will not do for a clawfoot tub. You’ll need specialized faucets.
Step 2 - Prepare
Turn off the water to the entire house or at the water shutoff valves in the floor, depending on your tub setup. Put a drop cloth down on the floor.
Step 3 - Remove the Supply Risers
Use an adjustable wrench and loosen all the slip nut connections. Your faucet kit may come with new risers leading from the floor supply pipes to the new faucet. If not, take care to preserve the old ones if possible. You may need to remove the drain as well so you have room to work.
Step 4 - Remove the Faucet
An adjustable wrench on the back of the tub allows you to remove the locknuts that attach the faucet securely to the tub. Using care, get a putty knife and scrape away the old putty from around the tub.
Step 5 - Install the New Faucet
Remember to use plumber's putty again to be sure the faucet doesn’t leak. If the supply risers are corroded, replace them as well.
