Water on the bathroom floor

Hey,

This is a strange one. 
Woke up to pop to the loo and on stepping on the carpet/mat in the shower-room of my 1993 VW Clubman GL, I found the mat to be wet. I must admit it has rained a lot recently, however I checked all over the interior of the room and can not fathom the source of the water!

Haven’t noticed the wet in there at all previously. Used the toilet last night and the mat was dry. Window isn’t open, flush is working normally, and like I said- nothing else in the room is wet at all- just the half of the mat nearest the door. It’s like someone poured a pint of water on it! It’s wet right through- just on the one side.

The ONLY thing I can think of is that there could be a problem with emptying the sink in the normal way- tipping it up- Then again, have done that only once since getting the van a fortnight ago. And not noticed any wet till now. 

Any ideas?
Thanks
Clare

Any chance that water is coming  up the shower drain? Is the  plug in? Friends of ours who had a 1993 Clubman said that the shower did not drain well due to odd plumbing. We had a wet floor outside the bathroom and that was due to a slight .leak where the sink tap and pipes joined. Best of luck tracing the source

The problem with tip up basins is that they can spill water down the wall and consequently onto the floor if you either tip them too quickly, or if the drain hole into which the water pours becomes blocked.

If you remove the basin itself, you will see the funnel shaped drain and be able to clear it if necessary. If it’s not blocked, try tipping it very slowly next time you use it.

Our previous (non-AS) motorhome had a tip up sink and we found that using normal bar soap tended to make the small drain hole block quite quickly; when we changed to using liquid soaps that eliminated the problem.

Thanks folks, will look into these and let you know.
