For that kind of money, you would think they would be proud enough to put their name on it. I bet its there somewhere, just have to look everywhere on the handle/s, trim plate, spout, even the back side of the spout it its a sink faucet (a mirror helps here). If tub/shower fuacet, it may even say it on the shower head. Other than that, post a couple pics here and we will see what we can come up with. Hope its a Moen, Delta, American Standard, or Kohler, as they have good warrantys, Moen and possibly even some of the others have lifetime warranty. Good luck, and let us know.
