A drain stopper and/or strainer comprises a stem, a cap preferably detachably attached to an upper end of the stem, a bristle strainer sleeve having a plurality of bristles removably received on the stem, and retaining means preferably detachably attached to the lower end of the stem for holding the bristle strainer sleeve on the stem. Retaining means include a two-prong fork that engages a pivot or ball rod between the forks, a plate having one or more holes for receiving a pivot or ball rod and an object that does not connect to anything other than the stem. A cap seal is included for stopper and strainer functionality and is omitted for strainer-only functionality. The bristle strainer sleeve may be designed to engage an inside wall of a drain pipe for holding the stopper and/or strainer in a desired position.
