Unless otherwise stated, all plumbing products made by Kohler come with a one-year limited warranty. This covers the products against workmanship defects and manufacturing faults; if your faucet's parts are missing, faulty, or not performing at the expected level, Kohler will replace them speedily. Some Kohler products have a longer warranty period. The limited lifetime warranty, found on some products across Kohler's ranges, is valid for as long as the original purchaser owns their home. This provides long-lasting peace of mind if you're a homeowner in North America (the US, Canada, and Mexico) with a Kohler faucet installed.
