I know it may be the same as any other models that have the full sunken shower in them. The P-Trap is leaking under the shower and I need to replace it. The guy before me put a ton of plumbers puddy around the flange thinking he was fixing the problem and that just was a bandaid. The coupling is plastic and I want to just go to lowes and replace it with something real. If I have to modify it I will but need to fix this leak before my floors need to be replaced.
