Coachmen: Shower Leaking

[DRosedale]

I have a 2011 Coachmen Concord 300TS, with a shower leak. I have determined that the leak is in the right front corner of shower where the wall panel meets the shower pan. I removed the silicone, cleaned and dried the area and replaced the silicone, slowed the leak, but it continues. I talked to tech at dealership and he recommended pulling the wall out a little and filling with silicone, did this and still leaks. Tech has now recommended sealing the entire shower where the wall meets the shower pan. He said water must be getting on the ledge between the wall and shower pan, then running around to the corner and leaking out. He said the factory sometimes cuts down the corners of the pan to get the pan to fit right in the shower stall. As information I checked the drain and it is tight, poured water down it and watched from the inspection hole under the shower. I then poured water in the right front corner and it poured out from under the shower, so I know it's coming out at this location. Any suggestions would be appreciated and what are your thoughts about sealing the entire shower as suggested by the tech.

Thanks in advance for any help and suggestions.

When you pour water in the right front corner, does water leak on the floor, or under the floor into the basement? It is beginning to sound like a crack in the shower base itself. You may want to plug the drain hole, and slowly pour water into the shower in small increments to locate the exact level of the crack or hole.

I had a shower leak that was difficult to find. This may not be your situation but mine leaked because when someone was actually in the shower, the p trap would hit the bottom of the pan and bend to the side creating a gap at the drain and shower floor connection. The dealer installed a shorter p trap which seems to have solved the problem.
