<p>An adjustable drain apparatus (10, 100) includes a drain base (20, 104) received within a floor. A flange (18, 24, 116) is coupled to the drain base. A ring (26, 124) is disposed in a flange cavity (19, 25, 120) and selectively movable therein. A grate (12, 108) is coupled to the ring. At least one retainer (140, 142) is coupled to the flange to retain the ring in the flange cavity. Preferably, two opposite rings (140, 142) selectively secure the ring in the flange. The flange has two different orientations with respect to the drain base to selectively position the grate at two different elevations with respect to the drain base.</p> |
