I'm doing a remodel in my small guest bathroom. I've pulled up the existing flooring (vinyl sheet on 1/4" underlayment) and put down additional 5/8" plywood to bring the subfloor up to snuff. Next I will be installing Ditra, and finally 12" ceramic tiles on point.
Do I need to do anything special to seal the subfloor off to protect from a leaky toilet or tub/toilet overflows? I'm looking at the cutout around the toilet flange and thinking that if the toilet seal ever leaks, I will have water under the tile which seems really bad. Also, if the tub or toilet ever overflow and it gets to the wall it could do the same thing.
