Shower floor crack

[chrisinkanata]

The floor of the shower in our 28' Laredo has what appears to be a crack in it. I can't see that any water is leaking out when we use it but it certainly will get to that point sooner rather than later. We recently had a leak in the fresh water tank that was removed and 'plastic welded'. Works perfectly now. Any idea if these shower floor pans can be repaired like this or has anyone else had this issue?

Thanks,

Chris
