Embodiments of the present invention address deficiencies of the art in respect to bottle traps and provide a bottle trap with an integral gas seal. In an embodiment of the invention, a bottle trap can include a body with both an inlet at a top portion of the body adapted to receive a tailpiece from a sink, and an outlet at a side portion of the body adapted to receive a horizontal drain pipe. The bottle trap further can include an integral metallic gas seal disposed within the body and defining two chambers of the body. The integral metallic gas seal can include a metallic wall being rigidly and non-removably coupled to an interior portion of the body at one end of the metallic wall and having an unattached distal end opposite to the top portion of the interior wall so as to permit passage of fluid from one of the chambers to another of the chambers. Optionally, the unattached distal end of the metallic wall can include a rounded tip.
