Renderings floors with environments

I have had pretty good success rendering medium table top products on a reflective surface with shadows with PV360.

I now need to render a large device , 10 foot x 8 foot x 3 foot. It is made of reflective material and I want an environment to be reflected in it.

I also want a tile floor under it with reflections and shadows. I Can't seem to get both??? I get the environment reflection (factory environ) but if I add

a surface for the floor it seems to block the environment affects. Any ideas? Thanks all and Happy Holidays
