What is the best material to use to replace sub flooring in my mobile home? Also, what kind should I use in the bathroom?
By Lorraine from Bristol, CT
When we redid an older mobile home, we used 3/4 inch regular plywood in the bedrooms, living room, and waterproof 3/4 inch ply in the bathrooms and kitchen. It does cost a little more, but there was already particle board there, and it was worn out and sagging.
We're with fatboyslimsmom, you really have to use that 3/4 waterproof plywood in the bathroom or kitchen, wherever there's plumbing or the possibility of moisture. The DH and his father redid the floors in my father-in-law's mobile home and they're still holding strong eight years later, as opposed to the nasty particle board that had been in place beforehand.
If you're also having wall problems ( soft spots, moisture issues) in the bathroom and need to re-do them, also make sure to use green board rather than regular sheetrock.
Is insulation mandatory in replacing the sub-floor in a mobile home bedroom? If so what type of material, vapor barrier, etc. is best?
Sorry for a delayed answer but if you have not completed the job here are some suggestions. I would never consider using anything other than plywood. Added insulation is always a good idea but not mandatory.
Here is a link that has some very, very clear and easy to understand instructions to help do this type of job.
