Where is the drain stopper located on this faucet

Our faucet doesn\'t come with the drain assembly and there is no place on this faucet for the drain & stopper. You may purchase the pop up drain separately from us, which can be open or closed simply by pressing the top of the drain mechanism up or down. Please check the Faucet Accessories category to order. According to your sink with or without overflow, please choose the drain with or without overflow.
