I have a Kohler (sp) faucet in my master bath that's come loose. I've looked underneath for some kind of bolt to tight, but I don't see anything there to tighten. I'm wondering if it was fitted badly and the means to tighten it lays between the plywood and the granite top. Thoughts?
there has to be a large nut under both the hot and cold water taps. you need a basin wrench to tighten them. get a basin wrench, crawl under the sink and tighten the nuts.
Because you'll NEVER get a standard wrench up in there (I've tried, trust me), you'll have to pick up a cheap basin wrench at your local hardware store. See below link for pic.
