Stool placement, vinyl covering, yellow wax & core
I thought about my last comment on this subject. Its probably not either viable or in your scope to start tearing out a bathroom subfloor down to the joists and replacing it with something else. How about this: if the particle board floor is not too bad looking, can you lay down a 1/4 inch plywood floor on top of it? I guess they sell an exterior grade in that width and its made with a better glue for moisture.Then you can put down whatever topping you want, be it sheet vinyl (which is my choice)or vinly squares (not self-stick, they'lll never stay on the bathroom floor) or ceramic (aeh?!) I realize you have to take the toilet and the wash basin stand out to put this down,but it shouldn't take too long. I don't know if you have another bathroom in the meantime. When thats all down, then you just reset the toilet and you might need two wax rings etc because of the new height and all the rest, but at least you don't have to worry about putting your foot through the floor when your done. And instead of wax ring,,Theres a new type of connection out on the market now which is a pvc type of collar/pipe that ties in the toilet to the floor drain. You should see it at the hardware store. They say its a lot better than the wax. Just read the instructions carefully.
