A one-way drain hole plug that affords for easy, quick, and proper installation into a panel having drain hole. The one-way drain hole plug includes a seal portion made from a first material and a hollow bulb portion made from a second material that is harder and/or stronger than the first material. The hardness or strength of the second material prevents the hollow bulb portion and the base attached thereto from collapsing during installation of the one-way drain hole plug into the drain hole. However, the first material is soft or pliable enough to allow sufficient deformation of the drain hole insert as it is pushed through the drain hole and provide a liquid-tight fit with the panel.
