Good morning, thank you for your interest in our products! We use a standard size drain of 1 1/4 " for this sink. As it is a standard size drain, any drain will be able to work with this sink. We do not recommend a specific drain. If you have any further questions or concerns please feel free to reach out to us and we would be happy to assist you. Have a wonderful day!
