Abstract: A cover assembly for undersink piping is presented having cover pieces for the various piping sections of an undersink P-trap drain assembly. The pieces are configured to cover the various pipe sections of the P-trap and have integral, flexible collars at the ends thereof which overlap the junctures and fastening mechanisms between the different pipe sections. The invention further includes a cover piece for an offset grid drain which is used with a P-trap having a longitudinal slit, a flexible collar on one end, and a band which is placed over the slit cover piece and moved up along the cover piece to hold the slit piece together while the flexible collar is folded downwardly to cover the pipe juncture between the offset grid drain and a P-trap. In one embodiment, the band is removably attached to the integral cover.
