Faucet leaks when we turn the water on. We just replaced our tile around the tub. The tile man didn't put the faucet or handles back on when he was finished. Are we missing a step? We just used an Allen wrech to tighten it back on and sealed around it. It is leaking beneath the tub under the faucet.

Hopefully you have access to the underside and can check to see if the supply lines are connected properly. Many installations do not consider leaving access to replace faucets. Kohler makes frequent changes to their products which sometimes makes finding parts difficult. Some use valve stems, and others use cartridges; but they all should have a nut under the handle that keeps them secure. You could have a leak there. Simply tightening them slightly may do the trick; however, the rubber seal might be damaged and needs to be replaced. If this isn't helpful, a picture could help make a better answer.
