Having carpet replaced and have a soft spot in shower area. the installers are concerned about sub floor. Is it simply plywood? It is a National Tradewinds. Suggestions appreciated, thanks.
Just a suggestion...I recently replaced a totally rotten floor in the basement compartment where all the plumbing is located. I used a sheet of HDPE which is hard plastic sheet. It was easy to cut and work with. Sort of expensive but you'll never have to worry about rot, soft spots, etc.
