An air channel device is disclosed for spas or bath units which is mat-like and has a plurality of openings therein to permit the entry of air into a heated bath. The air channel mat is mounted to the interior of the spa bath unit at any desired location including the foot and seat areas. It is secured to the interior surface of the spa by interlocking retainers which seal the periphery of the air channel to the interior of the spa. Air is blown into the spa beneath the air channel mat and then escapes into the bath through the perforations in the mat. The air channel device of the present invention eliminates prior U-shaped exterior air channels which were susceptible to cracking and breakage. The present air channel provides a cushioning effect in the foot and seat areas and also permits uniform aeration for the heated bath.
