Leaking shower tray

tombeaux

These cracks recently showed up around our shower drain. Subsequently, we have small amounts of water on the ground under our 320S after showering. I’m confident these cracks are the culprit. There are dozens of YouTube entries outlining various RV fixes for dealing with the cracks and reinforcing the floor to prevent the flexing that caused the cracks. 

Can anyone share suggestions on access? It looks like going from underneath (removing the corrugated black panel that covers this are and the tanks) is the only option. Am I right?

The shower pan is above the TaB floor, the only thing coming out the bottom is the pipe to the gray tank.  Your best bet is to replace the shower drain pan assembly, or patch this one with an epoxy based material.  This issue has come up before, try doing a search here to find the,previous discussions.

Yeah, somebody cracked their pan (not by the drain) and used a fiberglass patching system and it sounds like it worked. For yours you might be able to remove the drain grate assembly and patch it without having to remove the entire pan. I'm not sure how easy it is to access the underside of the pan on a 320 but on a 400 you can get ok access through the panel below the pan.
