My bathtub faucet leaks, but is the leak originating from the spigot
from a bad gasket, or is it coming form the faucet handle? Maybe a bad
gasket or seat? Just want to make sure before i start taking things
If it is a mixer tap, the spigot has no replaceable parts, and cannot leak
Very likely one of the two faucet washers, or the valve seats are worn. Best
case is that the seats are fine, and you just need new washers. Best to
change them both, before the washers wear through, and metal-to-metal
grinding begins to groove the seats.
Some are rather tricky to take apart. IT is not the spigot as at most
all it has is the diverter. Since you indicated that it was a single handle
unit you will need a rebuild kit from the hardware store and it will likely
include instructions and maybe even a tool to help you dissemble the thing.
You can try to check out the manufacturer's web site and see if you can find
the model number so you can get the right rebuild kit.
Note: The idea of having everyone shower and start the project in the
morning is a good idea, likely from someone who has been there and done
