  • It has been recognized that it would be advantageous to develop a shower drain adapter that will allow a tile installer to utilize a bondable waterproof membrane with a conventional two-piece drain system (or “shower pan drain system”).

    The present invention provides a shower drain adapter system configured to allow use of a bondable waterproof membrane with a shower pan drain system, including a drain body and an integrated bonding flange extending upwardly from the drain body. The integrated bonding flange can be operable to be sealably attached to a bondable waterproof membrane to provide a substantially waterproof seal between the membrane and the adapter. A lower mating flange can be separable from the drain body, the lower mating flange operable to mate with a component of a shower pan drain system installable on a waste pipe. The lower mating flange can include a substantially rigid frame, and a pliable gasket disposed at least partially about the frame. The pliable gasket can have an inner diameter sized to correspond to an outer diameter of a portion of the drain body.

  • In accordance with another aspect of the invention, a lower mating flange for use in a shower drain adapter system is provided, including a substantially rigid frame having a plurality of fastener openings formed therein and having a drain body receiving opening formed in a center thereof. A pliable gasket can be disposed at least partially about the frame. The pliable gasket can have an inner bearing surface and a lower drain fitting bearing surface, and can be operable to: provide a seal between a drain body and the lower mating flange when a drain body is inserted into the drain body receiving opening; and provide a seal between the lower mating flange and a component of a shower pan drain system when the lower mating flange is coupled to the component of the shower pan drain system.

    In accordance with another aspect of the invention, a method of adapting at least one component of a shower pan drain system for use with a bondable waterproof membrane is provided, including: coupling a lower mating flange to an upper portion of a component of the shower pan drain system, the lower mating flange having a pliable gasket attached thereto that is sized to receive a drain body of a shower drain adapter therein, the drain body of the shower drain adapter having an integrated bonding flange extending upwardly therefrom; orienting the drain body within an opening in the pliable gasket; and positioning the integrated bonding flange by moving the drain body within the opening in the pliable gasket.

  • In accordance with another aspect of the invention, a method of adapting at least one component of a shower pan drain system for use with a bondable waterproof membrane is provided, including: coupling a lower mating flange to an upper portion of a component of the shower pan drain system, the lower mating flange having a pliable gasket attached thereto having an opening that is sized to receive a drain body of a shower drain adapter therein, the drain body of the shower drain adapter having an integrated bonding flange extending upwardly therefrom; and orienting an object having an outside diameter substantially the same as the outside diameter of the drain body within the opening in the pliable gasket; positioning the object by moving the object within the pliable gasket.

illustrates, in a partially sectioned view (taken along section 1-1 of the assembly of ), a shower drain assembly with which a shower drain adapter in accordance with the present invention is incorporated. The drain assembly 10 generally includes a lower drain fitting 12 (not shown in sectioned view) of the type well known in the art for use with a two-piece shower drain system (or a “shower pan drain system”) that conventionally incorporates a shower pan (not shown). A shower drain adapter 14 can be coupleable to or over the drain fitting 12 and can include a drain body 16 and a lower mating flange 18.
