There was a leak somewhere in the yucky back window....it cause a small amount of rot in the bathroom floor. Not anywhere near as bad as the front floor, but it still had to be addressed.

Out came the toilet (Duane had already removed the "black water" tank and plumbing underneath the bathroom floor).  No visible sign of rot here - but the floor felt "spongy".

Out came the plumbing and cabinet (that you've seen me re-finishing) and vinyl flooring to expose the rotted area.  Note that you can see to the outside of the trailer thru the floorboard near the tub - it was that rotten.

The under layer of the floor was mostly structurally sound.  He did have to replace some structural boards at the top left side of the photo, just like we did around the entire front of the trailer.  He treated this flooring with a rot-stabilizer made by Minwax and called it good. 

New flooring and support boards going back in place.

A little foam to fill the void space.

And the top layer to finish it all out! I know areas look kindof water-stained, but it's all sturdy and will be covered with brand new flooring eventually.   The hole for the toilet will be cut later as he re-installs the plumbing and black water tank.  Yum.
