Depending on your use of your bathroom sink, you may or may not need the option of keeping water in the sink. If you don’t want your bathroom sink to keep water in, get an open grid sink drain. These drains only let the water down and are particularly recommended if your sink is not equipped with an overflow system.
A pop up drain, or a touch down drain, or a finger touch drain, allow you to open and shut the sink drain with the touch of a finger. Based on your sink, choose whether your bathroom sink drain has an overflow or not. Another rarer, sink drain system is the lift and turn sink drain, which you must screw in and unscrew by hand.
For the gutsiest consumers, there is a wide selection of exotic sink drains, in a variety of different shapes and colors, that serve as the top of the pop up sink drains systems and will certainly turn heads.
