Sheet Plywood as flooring?

[diyplumber1980]

Is it possible to use sheet plywood as flooring? I'm thinking of using exterior grade plywood to replace half the flooring in a batghroom, where it has been water damaged. It currently has floorboards, several of these have sunk in due to a long term water leak, so was thinking of removing these 4 or five rows of boards and replace it was exterior plywood. If this is ok to do, what size should i use, 12mm or 18mm?

thanks in advance

Yes it's okay, 18mm will match your existing closer, they may still need packing out.

You can use ply, the size will depend on what size your floor boards are surely but I would not go less than 18mm.
