Abstract
A drain flange cover is provided for covering and hiding a drain flange in a sink or bathtub, which includes a drain cap and which may or may not include a longitudinal shaft and/or a strainer. The longitudinal shaft can be a perforated tube that serves as a strainer. Strainers can be cylindrical, regular-funnel shaped and inverted-funnel shaped. A drain stopper includes an open-close mechanism, a strainer and a drain flange cover. A drain stopper with a push-push mechanism can rest on a cross-member in a drain pipe, allowing easy removal to clean the strainer.
