My bathtub faucet is leaking. I do not know what type of manufacturer made the faucet. A plumber wants to charge me to remove the tile and replace all the plumbing work, but he never really tried to determine what type of faucet it is. Is this necessary to do this work or can I remove the steam a bring it to a plumbing store so they can figure out what type of brand it is.

The plumber wants to charge you for a new faucet and the labor of installation for a simple leak? Don't use him again. He's packing the service call.
I take it this isn't a one handled valve and that it's leaking from the spout and not the srem. Why are you taking the stem into a plumbing shop? You don't have to even know the brand name to change a faulty washer. I would shut the water off and remove the stem. Now run your finger around the seat to check for nicks or rough spots. If you find any replace the seat as well Go down to the hardware store and purchase a assortment of faucet washers and a new seat if necessary. One of the washers is sure to fit the stem. Replace the washer in the stem and reinstall the assembly. Good luck, Tom

A picture would be great here! If you can post one under go advanced when you post again we can tell you more. Maybe someone here will recognize it and be able to help you order parts... heck, some parts are under a lifetime warranty... depending on faucet, so see if you can get us a pic. Or two.
