We are planning to renovate one of the bathrooms in a 20 year old double-wide. The room is on the 'join', and the floor feels uneven and maybe soft under the carpet. I'm curious what we'll find when we pull up the carpet, and how hard it is to replace the subfloor? or whatever it is under there. Does anyone have an idea what we might find? Is replacing something like that within the capabilities of a rookie DIY'er?? Thanks for any help or tips.
