A drain protector includes a basket and a wiper. The basket includes a basket body having first water openings. The basket body includes a seal at an upper first end and a retention member at a lower second end. The basket body is sized to be received in an associated drain, the seal for directly sealingly engaging an outer surface of the associated drain, and the retention member for directly engaging an inner surface of the associated drain. The wiper includes a wiper body having second water openings. The wiper body is removably mounted within the basket body for entrapping debris within water and removing the debris from within the basket body.

A drain guard device for preventing particulates from entering a drain. The drain guard device includes a ring member having an outer circumference and an inner circumference. A groove extends radially along the entire inner circumference. The groove is dimensioned to removably receive a strainer. The ring member is a flexible flat annular ring having a uniform width between the outer circumference and the inner circumference. In use, the drain guard rests over a drain, wherein the lower side of the ring member is configured to frictionally engage an upper side of a surface, such as a floor or sink. The lower side of the ring member is configured to form a suction seal with the upper side of the surface, wherein both the strainer and ring member can be easily removed from the surface by hand when desired.

The present disclosure relates to popup drain stopper and popup drain stopper assemblies. The popup drain stopper includes a debris trap having a plurality of bristle arranged to trap debris flowing into a drainpipe in which the stopper is positioned. Popup drain stopper assemblies include the popup drain stopper with the debris trap and the ability to remove the drain stopper from the drainpipe without disassembly. The stopper includes a cylindrical shaped bristle body having the bristles and which is removable from the stopper assembly.

Shower drain assemblies and their components are disclosed. In examples, a shower drain assembly may include a receptor, a threaded flange, an optional hair strainer, a plate, and a protective cover. The receptor may include an upper portion and a lower portion. A portion of a threaded flange is receivable into the upper portion. An internal diameter of the lower portion may be less than any internal diameter of the threaded portion. A membrane may be coupled to an interior cavity of the threaded flange for pressure testing the drain assembly. The threaded flange may also include a tab to facilitate coupling of the threaded flange to the receptor and/or securing of a hair strainer inside the interior cavity of the threaded flange. A top surface of the threaded flange may include an inset to facilitate removal of a plate. The protective cover may protect the plate from damage.
