Shower leaking under shower on floor

[Rvretired]

We have a new Cedar Creek cottage 40cck. Have had it 3 months. Noticed a line of water on the floor at the bottom of the shower unit. Checked caulking and seals, cleaned the shower door tracks and dried everything. Tried it again and more water. Installed a shower curtain. Used shower. No water on doors and no water on inner most track in door assembly but still water on the floor. What could it be?

Take a close look at the seal around the drain.

We lifted the screw down drain cover off and checked the seal. Looked okay but we poured some water around it and then stepped into the shower to see if any of the water leeched out and it didn't. ⁉️

We had something similar to this in our 38FL shortly after taking delivery. I ended up re-caulking the door frame for the sliding door both inside and outside. I eventually cured it, after several attempts, by pulling out the old sealant from the interior corners at the bottom of the sliding door frame (actually in the runners for the doors) and re-sealing them.

We'd also re-sealed the drain after a few months because I found a small amount of water leaking out after I'd gone in to the inspection door looking for something else.

I had also found a hairline crack in the corner of the shower floor - apparently a frequent problem with the CC showers caused when they are installed (according to the dealer). FR paid for that to be heat treated by a specialist company who work with fibreglass. Now, looking at it, you would never know the crack had been there.

Thanks Hutch,
We are going to try everything you mentioned but I am still so confused. I dried the tracks, used the shower curtain, and when I got out the shower doors were dry. However the outside door track had water in it and then the water started coming out at the floor again. Doesn't even seem possible.

Is there a small access panel on the front of the shower pan?

Water seepage is extremely difficult to source. Ask any big boater! Re seal everything and as mentioned get a magnifying glass, put pressure on the shower floor and look for hairline crack. Got to be coming from some place!

Hopefully you have access to the underside, it sounds like the drain nut needs to be tightened.

[Rvretired]

Thanks Telstar! I will check to see if we can get to that. It has to have something to do with the drain or the fiberglass bottom of the shower because everything else is dry. Thanks again.

My issue was the P-trap was loose and water would run into the kitchen floor and basement floor. I pulled down the storage wall and found that the plastic piece coming from the shower drain was loose plus it was cut too short. I suppose with the road twisting and general movement it worked loose.
I bought a new straight piece and cut it about 3" longer to go into the P-trap then hand tightened everything as well as I could. It's a bitch getting your fat hand into the saw cut hole accessing the shower drain. I was about to cut out a bigger hole but ended up just leaving the wall down for my next trip. Luckily all is well and no leaks now. I've since felt confident enough to reinstall the wall.

I had exactly the same problem last year in a 2005 Class C rental unit I bought. Was able to reach through and tighten it, and expect to have to redo that yearly.

Mine leaked anytime water was draining from the kitchen/bathroom sinks as they all go through that location to get to the grey water tank.

I dont have an access door in the coach and I haven't slid under to see what I might have access to there. No water on the concrete under the coach though. Seems like that is a positive. I cant thank all of you enough.

They don't use a ptrap on that model has a flapper but should be able to access from utility door

Dear edt,
Where is utility door located? Outside?

[florabama]

Had the same problem on a motorhome and it was the faucet. The water was leaking out the back of the faucet, bad valve or seal. Changed faucet and problem fixed.

On our old Sandpiper, it was the drain leaking. When you stepped in the shower, the koan would give a bit letting the drain leak. Upon inspection, they used no plumbers putty between the flange and the tub. I fixed it the way it should have been done. No leaks are acceptable.

Not sure on the location for the Cottage but on my 5er there is a small lockable door on the outside of the rig very close to the location of the shower. If the access is like most there is only a very small space (and usually at a completely obscure angle) in which to do anything. You almost have to be double jointed.

We have a 2015 REV RB. The entire panel below the shower door can be removed with a few screws. Also if you have any vents there, such as heat duct vent, try removing that to be able to look in. We have a glass shower door and the aluminum frame leaked where it was sealed to the shower.

It really made a difference if one of the corners of the coach was lower. The front passenger corner lower, made it leak at the front of the shower.
