Shower leaks onto bedroom carpet

I have a 2007 Winnebago Sightseer and recently picked up a new problem. When someone showers the carpet between the bed and the bathroom gets quite wet. As far as I can tell water is traveling from the shower along the floor under the carpet and pooling in a spot just behind the toilet area and the bet.
Had it checked at an RV shop and was assured it is not the toilet leaking (which was my first thought). RV place did not come up with a solution but it seems to happen only after showering.
I checked all the water lines I could access but was very limited in what lines I could trace.
There has been no back up from the gray water and the problem exists whether the tanks are empty or partially full.
Any ideas as to what might have all of a sudden happened to cause this leaking?

There should be an access panel behind the shower control valve, you can check for leaks. It is also possible to leak at the shower head in the wall. Contact Winnebago for a plumbing schematic. Water leaks are a pain in the neck, good luck.

Most likely the pan drain, Some pans flex quite a bit when someone is showering and the seal between the pan and drain pipe will leak,

You could also have a leak in the drain piping under the raised shower pan. You probably have a vent cover over the access hole to look under the shower pan. That is a cramped area and possibly the tech that installed it may not have done a good job of gluing and sealing the plastic piping. If you look under there with a flashlight while the shower is running, and feel the piping with your fingers, you will find out. (I had a small leak there on mine.) The water ran onto the floor, to the rear of the shower.
If at first you don't succeed, skydiving is not for you.

Our shower appears to be 2 piece, the pan and the surround. May be leaking where they meet.

On my Gulf Stream, I found the Shower Drain Line had broken off the piping under the bathroom Vanity. I took the opportunity to redo the complete bathroom. I replaced the Shower Drain Line with a Hepvo inline Trap Hepvo Waterless Valve, replaced the stand the toilet mounted on and installed new Vinyl Flooring. I repaired the broken line under the Vanity with a Fernco Coupling so the line now has a little give to reduce the strain on the couplings and provided proper support for the line. If I could have got the one piece Tub & Surround combination out of the bathroom proper I would have been able to place the Vinyl all the way across the bathroom floor and cleaned up some more minor problems. I believe Gulf Stream installed the Tub assembly and then built the remainder of the bathroom walls.

We had that problem after nearly a year of living in the RV. Turned out that the faucet portion wasn't sealed properly and water was getting behind that and running down the backside of the shower.

The leak is only when you use the shower? If so the line leading from the valve to the shower head is only pressured when you have the water running. If you did not drain the water out before winter completely water will sit in this pipe and swell and break the line. So it only leaks when you shower. Remove the access panel behind the shower or you might have to cut the wall. Don't see the pan leaking this bad this fast.

How's the caulking around the seams? Is the door sweep in good shape? Lot easier fixes than drains, faucets, etc. I'd try them first.

Here on iRV2 do a search on "shower leaks" or "shower drains". This subject has been talked about before and some excellent responses have been posted.

I'll have to agree with GreggOK80, I thought for sure my leak was surround, not previously winterized well, leaked when the shower was running, not pouring out. I didnt have access on the back wall, the valve come out thru the front and low and behold a hair line crack, not saying thats it but after I resiliconed mine still leaked, Good luck
