I have a small cabin (20x24) located in an area with sandy soil. The
foundation is wood as is the floor of the basement which is 3/4" plywood
(presumably treated) over 2x8 floor joists.

I'm installing radiant tubing in the building including in the basement.

There appears to be no rot or weakness in the plywood flooring.

Looking for options for floorcovering: bamboo, ceramic

Any thoughts, suggestions or potential problems? One issue is IF plywood
ever needs replacing, perhaps I need something removable.

Building is about 20 years old and there appears to be no moisture issues
(yet).
