A floor waste drain deodorizer apparatus (10), which is used with a floor grille (12) of a waste drain, has a container (14) having a perforated base (16) and a sidewall (18) extending upwardly from the base to define an open top (20). There are engagement means in the form of first and second holes (24, 26) formed in the sidewall (18) of the container (14) which are adapted to respectively engage first and second projections (28, 30) formed on the grille (12) so as to releasably engage the underside of the floor grille. This allows, in use, the container (10) to hang from the grille (12) and be surrounded by the drain adjacent the grille. A deodorizing preparation, which is an air freshening or scented substance in the form of a tablet (22), is located within the container for concealing odours.
