Replace damaged wood subfloor

Once the rotten wood is removed, the wood should be replaced with new plywood. This step should also include prepping the subfloor for the new bathroom flooring. The subfloor should be level and thick enough for the new floor. Most subfloors should be two layers thick; ask a flooring pro for the required subfloor thickness under the new floor.
