Replace Flooring After a Toilet Leak

Fixing an RV toilet


I own a 1999 Holiday Rambler Endeavor and am wondering how I replace the tile and sub-floor around a toilet after a toilet leak? I am a do-it-yourself RV owner.

Typically the floor of your RV is a sandwich design of wood panel, block foam insulation with framework, and an upper 1/2” plywood sheet. Some manufactures did put an additional thin subfloor for tile while others did not.

You should be able to remove the tile with a strong putty knife or wood chisel and get a good look at what is underneath. If you let it dry really good, you may not need to replace the sub-floor at all.

My folks had water lines burst on their Class A several years ago and we peeled the carpet back, let it dry, and it was good for years. If the wood is rotten, you can cut out the damaged section and replace it with the same thickness wood and re-tile.

Hope this helps,

    The air conditioning/heating unit shorted out when another camper plugged in to the electric pole I was using. Is there a reset button that I am not finding. I’m not seeing the make and model of the unit but I would bet that it is as old as the camper. Thank you in advance

    I'm trying to install 4mm plywood around the windows of our Bus and same with on the ceiling. I am having problems with measuring the half moons of windows and air vent. Whenever I seem to measure and cut and put it to fit it always seems out of whack. Any solutions on how to get the plywood properly installed around windows so it sits nice and flush

    I can't find a main electrical shut off switch inside the unit. It's a pain to disconnect batteries in storage.

    I bought a camper that needs a complete interior/exterior re-do and I have never done this. How do I install the floor so it is attached to the aluminum siding of the camper. Currently I can see gaps between the walls and the rotting floor.
