Plywood as a subfloor material traditionally exterior grade plywood has been the subfloor material of choice for many bathroom flooring projects. For hardwood tongue and groove cdx plywood rated ac with a 1 2 to 3 4 inch thickness is best.
Subfloor plywood is extremely strong and can support most floor types including plywood and treated plywood.
Best wood for bathroom subfloor. Plywood is made from glued thin strips of wood veneer called plies that are layered at alternating 90 degree angles and placed in a hot press. Plywood is familiar to most people it is a sheet material made from layers of wood oriented in opposite directions from layer to layer. The resulting cross laminated and layered material.
It provides a foundation that supports the top layer and protects it from damage. Consider what the top layer of the bathroom flooring will be since some types of plywood are better suited for different flooring. Older homes may have boards laid diagonally across the floor joists.

Plywood is made by gluing alternating layers of wood veneer. Cdx plywood is like other laminate plywoods but the outer layers of laminate are grades c and d which means they are cosmetically rough and contain many imperfections thus lowering their cost. The best type of subflooring to install depends on what type of finished floor you plan to have on top of it.
While osb is the most popular structural panel cdx plywood is the most popular type of traditional or veneer plywood. Most subflooring in wood frame construction today is either oriented strand board osb or plywood. Cdx plywood in particular is used often because it has a high level of resistance to moisture and humidity.
When building a new home or remodelling a structure a subfloor is the ideal base for a new floor.
