For some reason they make different interior parts. I had to change my soap bottle holder to make mine work, and you know what? It works well. I see no reason why they shouldn't be common. Remember that you must order the exact product that fits. I have shared dispensers in different locations and need to replace a few. The internals come out with a few small screws on the back.
