Abstract: An odor dispersion assembly for dispersing an odor from a receptacle to an external exhaust through an existing structure and at least one existing pipe. The assembly is operable to suck the odors at a proximal point to their discharge. A receptacle receives a discharge. The receptacle includes a seat for providing a surface for a user to sit for performing the discharge. The seat include at least one aperture that receives and directs the odor to a cavity within the seat. A pressure differential portion sucks the odor from the cavity. The odors passes through a dispersion tube behind the toilet, and through an existing barrier. The dispersion tube joins with at least one existing pipe and tubing behind the existing barrier. The existing pipes carries the odor to an exhaust portion. Existing pipes and structures are used to minimize costs.
