Tiling bathroom floor and countertop: Backerboard needed?

digexpressions

I will be tiling my bathroom floor as well as the countertop. I have installed hardibacker on the floor and am ready for the tile. Is it necessary to put the cement board on the counter as well, or is plywood okay?

The backerboard helps promote adhesion to the tile and substrate. The backer is going to be more rigid than the plywood and should not allow the top to flex and break. If you are wanting it to look nice, build it to last.

We've always installed the cement-board on counters that we have done tile on. Seal edges with silicone.

Example (tile backsplash installed later on):
