Does anyone know if I can place my new 48" double vanity directly on the AquaTough FiberRock backerboard or should a lay a piece of wood down? The backerboard is already over wood subflooring.

Thanks!

Why would you think there might be a problem doing that? It's just sittin there.

How did you install the board? What are you installing on it?

I followed the manufacturer's instructions for installing it over wood subflooring. The backerboard seems like it can dent almost as easily as drywall, so I wasn't sure I should put a big heavy thing right on it. My vacuum made a few marks on it so I lost some confidence in its durability. I thought the vanity might sink a little over time and become unlevel.

If tiling, tile it, then set the vanity, no cutting around it then.

Yes, you should install the tiles first. Why not, or are you doing something different?

I will install the tiles first. I guess I was going by the old vanity which was directly on the wood subflooring, but that just didn't seem right for backerboard.

Thanks everyone!
