Some do and some don’t. It all depends on the manufacturer if they include them or not. If one is not included, we recommend you purchase one from the same manufacturer as the faucet to guarantee the finish matches. You will also need to determine what type of drain you need. The most commonly used drains are either a grid drain or a pop-up drain. A grid drain will not allow you to stop up the sink whereas a pop-up drain will allow you to do so.
